[This is the first released version of the Lesser GPL. It also counts as the successor of the GNU Library Public License, version 2, hence the version number 2.1.] Preamble The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public Licenses are intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This license, the Lesser General Public License, applies to some specially designated software packages--typically libraries--of the Free Software Foundation and other authors who decide to use it. You can use it too, but we suggest you first think carefully about whether this license or the ordinary General Public License is the better strategy to use in any particular case, based on the explanations below. When we speak of free software, we are referring to freedom of use, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish); that you receive source code or can get it if you want it; that you can change the software and use pieces of it in new free programs; and that you are informed that you can do these things. To protect your rights, we need to make restrictions that forbid distributors to deny you these rights or to ask you to surrender these rights. These restrictions translate to certain responsibilities for you if you distribute copies of the library or if you modify it. For example, if you distribute copies of the library, whether gratis or for a fee, you must give the recipients all the rights that we gave you. You must make sure that they, too, receive or can get the source code. If you link other code with the library, you must provide complete object files to the recipients, so that they can relink them with the library after making changes to the library and recompiling it. And you must show them these terms so they know their rights. We protect your rights with a two-step method: (1) we copyright the library, and (2) we offer you this license, which gives you legal permission to copy, distribute and/or modify the library. To protect each distributor, we want to make it very clear that there is no warranty for the free library. Also, if the library is modified by someone else and passed on, the recipients should know that what they have is not the original version, so that the original author's reputation will not be affected by problems that might be introduced by others. Finally, software patents pose a constant threat to the existence of any free program. We wish to make sure that a company cannot effectively restrict the users of a free program by obtaining a restrictive license from a patent holder. Therefore, we insist that any patent license obtained for a version of the library must be consistent with the full freedom of use specified in this license. Most GNU software, including some libraries, is covered by the ordinary GNU General Public License. This license, the GNU Lesser General Public License, applies to certain designated libraries, and is quite different from the ordinary General Public License. We use this license for certain libraries in order to permit linking those libraries into non-free programs. When a program is linked with a library, whether statically or using a shared library, the combination of the two is legally speaking a combined work, a derivative of the original library. The ordinary General Public License therefore permits such linking only if the entire combination fits its criteria of freedom. The Lesser General Public License permits more lax criteria for linking other code with the library. We call this license the "Lesser" General Public License because it does Less to protect the user's freedom than the ordinary General Public License. It also provides other free software developers Less of an advantage over competing non-free programs. These disadvantages are the reason we use the ordinary General Public License for many libraries. However, the Lesser license provides advantages in certain special circumstances. For example, on rare occasions, there may be a special need to encourage the widest possible use of a certain library, so that it becomes a de-facto standard. To achieve this, non-free programs must be allowed to use the library. A more frequent case is that a free library does the same job as widely used non-free libraries. In this case, there is little to gain by limiting the free library to free software only, so we use the Lesser General Public License. In other cases, permission to use a particular library in non-free programs enables a greater number of people to use a large body of free software. For example, permission to use the GNU C Library in non-free programs enables many more people to use the whole GNU operating system, as well as its variant, the GNU/Linux operating system. Although the Lesser General Public License is Less protective of the users' freedom, it does ensure that the user of a program that is linked with the Library has the freedom and the wherewithal to run that program using a modified version of the Library. The precise terms and conditions for copying, distribution and modification follow. Pay close attention to the difference between a "work based on the library" and a "work that uses the library". The former contains code derived from the library, whereas the latter must be combined with the library in order to run. GNU LESSER GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. This License Agreement applies to any software library or other program which contains a notice placed by the copyright holder or other authorized party saying it may be distributed under the terms of this Lesser General Public License (also called "this License"). Each licensee is addressed as "you". A "library" means a collection of software functions and/or data prepared so as to be conveniently linked with application programs (which use some of those functions and data) to form executables. The "Library", below, refers to any such software library or work which has been distributed under these terms. A "work based on the Library" means either the Library or any derivative work under copyright law: that is to say, a work containing the Library or a portion of it, either verbatim or with modifications and/or translated straightforwardly into another language. (Hereinafter, translation is included without limitation in the term "modification".) "Source code" for a work means the preferred form of the work for making modifications to it. For a library, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the library. Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running a program using the Library is not restricted, and output from such a program is covered only if its contents constitute a work based on the Library (independent of the use of the Library in a tool for writing it). Whether that is true depends on what the Library does and what the program that uses the Library does. 1. You may copy and distribute verbatim copies of the Library's complete source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and distribute a copy of this License along with the Library. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 2. You may modify your copy or copies of the Library or any portion of it, thus forming a work based on the Library, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: a) The modified work must itself be a software library. b) You must cause the files modified to carry prominent notices stating that you changed the files and the date of any change. c) You must cause the whole of the work to be licensed at no charge to all third parties under the terms of this License. d) If a facility in the modified Library refers to a function or a table of data to be supplied by an application program that uses the facility, other than as an argument passed when the facility is invoked, then you must make a good faith effort to ensure that, in the event an application does not supply such function or table, the facility still operates, and performs whatever part of its purpose remains meaningful. (For example, a function in a library to compute square roots has a purpose that is entirely well-defined independent of the application. Therefore, Subsection 2d requires that any application-supplied function or table used by this function must be optional: if the application does not supply it, the square root function must still compute square roots.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Library, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Library, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Library. In addition, mere aggregation of another work not based on the Library with the Library (or with a work based on the Library) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 3. You may opt to apply the terms of the ordinary GNU General Public License instead of this License to a given copy of the Library. To do this, you must alter all the notices that refer to this License, so that they refer to the ordinary GNU General Public License, version 2, instead of to this License. (If a newer version than version 2 of the ordinary GNU General Public License has appeared, then you can specify that version instead if you wish.) Do not make any other change in these notices. Once this change is made in a given copy, it is irreversible for that copy, so the ordinary GNU General Public License applies to all subsequent copies and derivative works made from that copy. This option is useful when you wish to copy part of the code of the Library into a program that is not a library. 4. You may copy and distribute the Library (or a portion or derivative of it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange. If distribution of object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place satisfies the requirement to distribute the source code, even though third parties are not compelled to copy the source along with the object code. 5. A program that contains no derivative of any portion of the Library, but is designed to work with the Library by being compiled or linked with it, is called a "work that uses the Library". Such a work, in isolation, is not a derivative work of the Library, and therefore falls outside the scope of this License. However, linking a "work that uses the Library" with the Library creates an executable that is a derivative of the Library (because it contains portions of the Library), rather than a "work that uses the library". The executable is therefore covered by this License. Section 6 states terms for distribution of such executables. When a "work that uses the Library" uses material from a header file that is part of the Library, the object code for the work may be a derivative work of the Library even though the source code is not. Whether this is true is especially significant if the work can be linked without the Library, or if the work is itself a library. The threshold for this to be true is not precisely defined by law. If such an object file uses only numerical parameters, data structure layouts and accessors, and small macros and small inline functions (ten lines or less in length), then the use of the object file is unrestricted, regardless of whether it is legally a derivative work. (Executables containing this object code plus portions of the Library will still fall under Section 6.) Otherwise, if the work is a derivative of the Library, you may distribute the object code for the work under the terms of Section 6. Any executables containing that work also fall under Section 6, whether or not they are linked directly with the Library itself. 6. As an exception to the Sections above, you may also combine or link a "work that uses the Library" with the Library to produce a work containing portions of the Library, and distribute that work under terms of your choice, provided that the terms permit modification of the work for the customer's own use and reverse engineering for debugging such modifications. You must give prominent notice with each copy of the work that the Library is used in it and that the Library and its use are covered by this License. You must supply a copy of this License. If the work during execution displays copyright notices, you must include the copyright notice for the Library among them, as well as a reference directing the user to the copy of this License. Also, you must do one of these things: a) Accompany the work with the complete corresponding machine-readable source code for the Library including whatever changes were used in the work (which must be distributed under Sections 1 and 2 above); and, if the work is an executable linked with the Library, with the complete machine-readable "work that uses the Library", as object code and/or source code, so that the user can modify the Library and then relink to produce a modified executable containing the modified Library. (It is understood that the user who changes the contents of definitions files in the Library will not necessarily be able to recompile the application to use the modified definitions.) b) Use a suitable shared library mechanism for linking with the Library. A suitable mechanism is one that (1) uses at run time a copy of the library already present on the user's computer system, rather than copying library functions into the executable, and (2) will operate properly with a modified version of the library, if the user installs one, as long as the modified version is interface-compatible with the version that the work was made with. c) Accompany the work with a written offer, valid for at least three years, to give the same user the materials specified in Subsection 6a, above, for a charge no more than the cost of performing this distribution. d) If distribution of the work is made by offering access to copy from a designated place, offer equivalent access to copy the above specified materials from the same place. e) Verify that the user has already received a copy of these materials or that you have already sent this user a copy. For an executable, the required form of the "work that uses the Library" must include any data and utility programs needed for reproducing the executable from it. However, as a special exception, the materials to be distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. It may happen that this requirement contradicts the license restrictions of other proprietary libraries that do not normally accompany the operating system. Such a contradiction means you cannot use both them and the Library together in an executable that you distribute. 7. You may place library facilities that are a work based on the Library side-by-side in a single library together with other library facilities not covered by this License, and distribute such a combined library, provided that the separate distribution of the work based on the Library and of the other library facilities is otherwise permitted, and provided that you do these two things: a) Accompany the combined library with a copy of the same work based on the Library, uncombined with any other library facilities. This must be distributed under the terms of the Sections above. b) Give prominent notice with the combined library of the fact that part of it is a work based on the Library, and explaining where to find the accompanying uncombined form of the same work. 8. You may not copy, modify, sublicense, link with, or distribute the Library except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense, link with, or distribute the Library is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. 9. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Library or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Library (or any work based on the Library), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Library or works based on it. 10. Each time you redistribute the Library (or any work based on the Library), the recipient automatically receives a license from the original licensor to copy, distribute, link with or modify the Library subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties with this License. 11. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Library at all. For example, if a patent license would not permit royalty-free redistribution of the Library by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Library. If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply, and the section as a whole is intended to apply in other circumstances. It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. 12. If the distribution and/or use of the Library is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Library under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. 13. The Free Software Foundation may publish revised and/or new versions of the Lesser General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Library specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Library does not specify a license version number, you may choose any version ever published by the Free Software Foundation. 14. If you wish to incorporate parts of the Library into other free programs whose distribution conditions are incompatible with these, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. NO WARRANTY 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. END OF TERMS AND CONDITIONS How to Apply These Terms to Your New Libraries If you develop a new library, and you want it to be of the greatest possible use to the public, we recommend making it free software that everyone can redistribute and change. You can do so by permitting redistribution under these terms (or, alternatively, under the terms of the ordinary General Public License). To apply these terms, attach the following notices to the library. It is safest to attach them to the start of each source file to most effectively convey the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found. Copyright (C) This library is free software; you can redistribute it and/or modify it under the terms of the GNU Lesser General Public License as published by the Free Software Foundation; either version 2 of the License, or (at your option) any later version. This library is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU Lesser General Public License for more details. You should have received a copy of the GNU Lesser General Public License along with this library; if not, write to the Free Software Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA Also add information on how to contact you by electronic and paper mail. You should also get your employer (if you work as a programmer) or your school, if any, to sign a "copyright disclaimer" for the library, if necessary.

src/modules/sdl/consumer_sdl_preview.c: Make mlt_consumer_purge() more thorough. (SF-187) This is applied to SDL consumers only at the moment since that is what most applications are using. Needs to be extended to other consumers. 2013-04-12 Dan Dennedy * configure, src/framework/mlt_version.h: Set interim version 0.8.9. 2013-04-07 Brian Matherly * src/modules/gtk2/producer_count.yml, src/modules/oldfilm/filter_dust.yml, src/modules/oldfilm/filter_grain.yml, src/modules/oldfilm/filter_oldfilm.yml: Misc YAML fixes 2013-04-06 Dan Dennedy * src/framework/mlt.vers, src/framework/mlt_service.c, src/framework/mlt_service.h, src/mlt++/MltService.cpp, src/mlt++/MltService.h, src/mlt++/mlt++.vers: Add mlt_service_move_filter() and Mlt::Service::move_filter(). 2013-04-04 Brian Matherly * src/modules/gtk2/Makefile, src/modules/gtk2/factory.c, src/modules/gtk2/producer_count.c, src/modules/gtk2/producer_count.yml: Add new count producer 2013-03-21 Dan Dennedy * src/modules/avformat/factory.c, src/modules/avformat/filter_avresample.c: Restore avresample filter when build against FFmpeg. This provides a LGPL audio resampler, but it is using deprecated APIs. Support for swresample or libav avresampler is another project. 2013-03-20 Dan Dennedy * src/modules/avformat/consumer_avformat.c, src/modules/avformat/producer_avformat.c: Add support for libavformat and libavcodec major version 55. 2013-03-18 Dan Dennedy * src/modules/avformat/Makefile, src/modules/avformat/configure, src/modules/avformat/consumer_avformat.c, src/modules/avformat/factory.c, src/modules/avformat/filter_avcolour_space.c, src/modules/avformat/filter_avdeinterlace.c, src/modules/avformat/filter_avresample.c, src/modules/avformat/filter_swscale.c, src/modules/avformat/producer_avformat.c: Drop support for FFmpeg v0.5 and v0.6 and require swscale.

Instead of passing an int cast as pointer. 2013-03-21 Dan Dennedy * src/modules/frei0r/factory.c, src/modules/frei0r/frei0r_helper.c, src/modules/frei0r/param_name_map.yml: Add a frei0r param name mapping system. For apps that set frei0r parameters by their name, this provides backwards compatibility when a frei0r parameter name changes. 2013-03-17 Dan Dennedy * src/modules/frei0r/factory.c, src/modules/frei0r/frei0r_helper.c: Switch to indexed propery names for frei0r params. Properties supplied by frei0r param name are supported for backwards compatibility. 2013-03-13 Dan Dennedy * src/modules/core/loader.dict, src/modules/core/producer_loader.c: Tell loader how to use WebVfx. With my latest (merged) patches to WebVfx, one can load plain old HTML and QML files. They do not need webvfx script to initialize rendering - with some caveats about the meaning of document-loaded. However, without this loader change, plain resources need to prefaced with "plain:". The loader producer can now do that and instead "webvfx:" is needed to tell webvfx to wait for script in the content to call WebVfx.renderReady(true) (unless you use "webvfx:plain:..."). Also, WebVfx can also now load HTML over HTTP. This is especially handy if your content is updating itself with data from a web service. Otherwise, you will run into cross-site-scripting errors. 2013-03-07 Dan Dennedy * src/modules/opengl/filter_movit_crop.cpp, src/modules/opengl/filter_movit_opacity.cpp, src/modules/opengl/filter_movit_resample.cpp, src/modules/opengl/filter_movit_resize.cpp, src/modules/opengl/transition_movit_mix.cpp, src/modules/opengl/transition_movit_overlay.cpp: Add locking to opengl services for thread protection. * src/modules/opengl/filter_glsl_manager.cpp, src/modules/opengl/glsl_manager.h: Make opengl filters support attach, detach, and disable. 2013-03-03 Dan Dennedy * src/framework/mlt.vers, src/framework/mlt_service.c, src/framework/mlt_service.h, src/mlt++/MltService.cpp, src/mlt++/MltService.h, src/mlt++/mlt++.vers: Add mlt_service_filter_count and Mlt::Service::filter_count. 2013-02-25 Brian Matherly * src/modules/avsync/Makefile, src/modules/avsync/consumer_blipflash.c, src/modules/avsync/consumer_blipflash.yml, src/modules/avsync/factory.c, src/modules/avsync/producer_blipflash.c, src/modules/avsync/producer_blipflash.yml: Add new avsync module 2013-02-24 Dan Dennedy * src/framework/mlt_frame.c, src/modules/core/consumer_multi.c: Let qglsl multi consumer work with more consumers.

I don't like the idea of versioning the melt binary. But kdenlive is the main user of MLT and it expects the same formats support from both the libmltX it is linked to, and the melt binary it uses to do the actual work. 2013-01-20 Dan Dennedy * Doxyfile, configure, docs/melt.1, src/framework/mlt_version.h, src/melt/melt.c: Set version to 0.8.8. 2012-12-31 Dan Dennedy * src/modules/avformat/consumer_avformat.c, src/modules/avformat/producer_avformat.c: Fix build against FFmepg 0.5 and 0.6. 2012-12-26 Niv Sardi * src/modules/gtk2/producer_pixbuf.c, src/modules/gtk2/producer_pixbuf.yml: pixbuf producer: loop option to loop sequence selectively 2012-12-22 Dan Dennedy * src/framework/mlt_consumer.c, src/framework/mlt_frame.c, src/framework/mlt_types.h, src/modules/avformat/consumer_avformat.c, src/modules/avformat/producer_avformat.c, src/modules/core/filter_audiochannels.c, src/modules/core/filter_audioconvert.c, src/modules/core/filter_channelcopy.c, src/modules/core/filter_mono.c: Add mlt_audio_u8 (sourceforce-182).

An app can register a mlt_log callback, trap errors, and do something more graceful than abort as perhaps some of these are not really as fatal as they claim to be (a different patch can change the levels as needed). 2012-11-14 Dan Dennedy * Doxyfile, NEWS, configure, docs/melt.1, src/framework/mlt_version.h: Set version to 0.8.6 2012-11-13 Dan Dennedy * Doxyfile, configure, docs/melt.1, src/framework/mlt_version.h, src/modules/avformat/configure: Set version to 0.8.4 2012-11-11 Dan Dennedy * src/modules/core/factory.c, src/modules/normalize/Makefile, src/modules/normalize/factory.c, src/modules/normalize/filter_audiolevel.c, src/modules/normalize/filter_audiolevel.yml: Add audiolevel filter. * src/modules/avformat/producer_avformat.c, src/modules/avformat/producer_avformat.yml, src/modules/core/filter_resize.c: More fixes for force_full_luma (kdenlive-2799). This change lets the image converter downstream of the avformat producer perform utilize the range as-needed. Then, when the rescale filter sees that the force_full_range is set on the frame but has not yet been applied, forces a conversion to RGB to enforce it. In addition, the recently added force_full_luma property on the avformat producer is removed because it is redundant with AVOption color_range=2. * presets/consumer/avformat/Sony-PSP,

This is a major change from the previous model of moving work items (frames) from one queue to another. This new model improves the behavior of realtime mode and performance overall. In the new model, a single queue is used along with an is_processed flag on the frame. Also, there is an index into the queue (process_head) that indicates from which point should a worker consider fetching the next unprocessed frame. There are situations in realtime mode where the processing of a frame takes longer than the queue (or from head to its fetch index). Over extended periods of this heavy processing, the video frame in the consumer may never be updated (rendered=1)! To remedy this, the consumer detects this and automatically moves the process_head towards the tail, but even this may not be good enough. The only real remedy is to increase buffers and suffer with poor latency. If lower latency is preferred, then it may be better to not use realtime mode and permit audio discontinuity. * src/framework/mlt_deque.c, src/framework/mlt_deque.h: Add mlt_deque_peek() with index. 2010-06-14 Dan Dennedy * src/framework/mlt_consumer.c, src/framework/mlt_frame.c, src/framework/mlt_tractor.c, src/modules/core/filter_imageconvert.c, src/modules/sdl/consumer_sdl.c: Fix image format consistency and conversion. 2010-06-11 Dan Dennedy * src/framework/mlt_consumer.c, src/framework/mlt_tractor.c: Remove the tractor service locking. This completely inhibited parallelism, but removing it also exposes more race conditions that require resolution. 2010-03-04 Dan Dennedy * .../motion_est/filter_autotrack_rectangle.c, src/modules/motion_est/filter_crop_detect.c, src/modules/motion_est/filter_motion_est.c, src/modules/normalize/filter_volume.c, src/modules/oldfilm/filter_dust.c, src/modules/oldfilm/filter_lines.c, src/modules/plus/filter_affine.c, src/modules/plus/transition_affine.c, src/modules/qimage/producer_kdenlivetitle.c, src/modules/qimage/producer_qimage.c, src/modules/sox/filter_sox.c, src/modules/vorbis/producer_vorbis.c: Add service locks for parallelism. * src/modules/avformat/filter_avresample.c, src/modules/avformat/filter_swscale.c, src/modules/avformat/producer_avformat.c, src/modules/core/filter_data_show.c, src/modules/core/filter_luma.c, src/modules/core/filter_watermark.c, src/modules/core/producer_colour.c, src/modules/core/transition_composite.c, src/modules/core/transition_luma.c, src/modules/core/transition_region.c, src/modules/effectv/filter_burn.c, src/modules/frei0r/filter_frei0r.c, src/modules/frei0r/producer_frei0r.c, src/modules/frei0r/transition_frei0r.c, src/modules/gtk2/producer_pango.c, src/modules/gtk2/producer_pixbuf.c, src/modules/kdenlive/filter_freeze.c, src/modules/kdenlive/producer_framebuffer.c, src/modules/resample/filter_resample.c: Add service locks for parallelism. RGB filters and transitions from frei0r and burningtv are still not safe enough. * src/framework/mlt_consumer.c, src/framework/mlt_consumer.h: Add parallelism to mlt_consumer. To use set real_time greater than 1 for frame-dropping or less than -1 for no frame-dropping. It works better with a liberal buffer size. You can still set prefill less than buffer size, but it must be at least the same number as real_time, preferably a little higher to help with frame ordering. 2010-02-20 Dan Dennedy * src/framework/mlt_deque.c, src/framework/mlt_deque.h: Add mlt_deque_insert(). 2010-02-16 Dan Dennedy * src/framework/mlt_consumer.c, src/framework/mlt_consumer.h: Qualify queue, mutex, and cond vars with frame_queue_. 2011-01-23 Dan Dennedy * configure, src/framework/mlt_version.h: Move to an interim version number. 2011-01-17 Dan Dennedy * src/modules/sdl/consumer_sdl.c, src/modules/sdl/consumer_sdl_still.c: SDL tweaks for Windows discovered when embedded. * src/framework/Makefile, src/mlt++/Makefile, src/mlt++/config.h: On Windows install .def and version-less DLLs to let apps build against us. * src/framework/mlt_factory.c, src/modules/avformat/configure, src/modules/frei0r/factory.c, src/modules/jackrack/plugin_mgr.c: On Windows locate plugins and data by directory relative to current directory. lib\mlt lib\frei0r-1 lib\ladspa share\mlt share\ffmpeg 2010-12-31 Dan Dennedy * src/modules/xml/consumer_xml.c, src/modules/xml/producer_xml.c: Cleanup libxml changes for MinGW. * src/modules/jackrack/configure, src/modules/jackrack/jack_rack.c: Fix JackRack build on MinGW. * src/modules/qimage/Makefile, src/modules/qimage/configure, src/modules/qimage/producer_qimage.c, src/modules/qimage/qimage_wrapper.cpp, src/modules/qimage/qimage_wrapper.h: Fix qimage build for MinGW. 2010-12-30 Dan Dennedy * src/modules/xml/consumer_xml.c, src/modules/xml/producer_xml.c: Fix libxml2 build on MinGW. * src/modules/gtk2/Makefile, src/modules/gtk2/consumer_gtk2.c, src/modules/gtk2/producer_pixbuf.c: Fix gtk2 build on mingw. 2010-12-15 Dan Dennedy * src/melt/Makefile, src/melt/io.c, src/melt/melt.c, src/modules/sdl/consumer_sdl.c: Fix SDL and keyboard input on Win32. 2010-12-03 Dan Dennedy * configure, src/framework/Makefile, src/melt/Makefile, src/melt/io.c, src/mlt++/Makefile, src/mlt++/MltFactory.cpp, src/mlt++/MltFactory.h, src/mlt++/config.h, src/mlt++/configure, src/modules/avformat/Makefile, src/modules/core/Makefile, src/modules/core/producer_loader.c, src/modules/kino/configure, src/modules/motion_est/Makefile, src/modules/sdl/Makefile, src/modules/sdl/consumer_sdl.c, src/modules/sdl/consumer_sdl_audio.c, src/modules/sdl/consumer_sdl_preview.c, src/modules/sdl/consumer_sdl_still.c, src/win32/fnmatch.c, src/win32/fnmatch.h, src/win32/win32.c: Initial port to Windows using MinGW. Much of the credit goes to Michael Zenov. 2011-01-23 Dan Dennedy * Doxyfile, configure, docs/melt.1, src/framework/mlt_version.h: Set version to 0.6.2. 2011-01-16 Till Theato * src/modules/rotoscoping/Makefile, src/modules/rotoscoping/cJSON.c, src/modules/rotoscoping/cJSON.h, src/modules/rotoscoping/filter_rotoscoping.c: Rotoscoping: Add support for simple keyframes - current limits: - number of points has to be equal for all keyframes - points have to be in "correct" order (1. point in 1. kf will be moved to 1. point in 2. kf, ...) - the parameter "polygon" is now formated using json: - no keyframes: polygon="[[x,y], [x,y], ...]" - keyframes: polygon= '{ "framepos1" : [[x,y], [x,y], ...], "framepos2" : [[x,y], [x,y], ...], ...}' 2011-01-15 Till Theato * src/modules/rotoscoping/Makefile, src/modules/rotoscoping/factory.c, src/modules/rotoscoping/filter_rotoscoping.c: Add rotoscoping filter (WIP): It hides everything not in the polygon defined by the vertices given through the "polygon" parameter 2011-01-11 Dan Dennedy * configure, src/mlt++/configure, src/modules/avformat/configure, src/modules/kino/endian_types.h, src/modules/kino/riff.cc, src/modules/qimage/configure, src/modules/sox/configure: Enable build on NetBSD (3090684) * src/modules/kino/Makefile, src/modules/qimage/Makefile: Use CXX rather than CC for linking C++ (3090682) * src/modules/sdl/consumer_sdl_audio.c, src/modules/sdl/consumer_sdl_preview.c: Fix undefined bahavior in SDL module (3066195). The standard says the post-increment can have effect at any point between the previous and the next sequence point (or something similar), so the behavior of "this->refresh_count = this->refresh_count ++" is undefined. Patch by Cristian Morales Vega 2011-01-10 Dan Dennedy * src/modules/plus/interp.h, src/modules/plus/transition_affine.c: Add geometry opacity interpretation to affine. Also, fixes interpolation method selection and removes a redundant bounds test. 2011-01-10 j-b-m * src/modules/gtk2/producer_pixbuf.c, src/modules/qimage/producer_qimage.c: Add force_aspect_ratio to image producers. 2011-01-10 Dan Dennedy * configure, src/framework/mlt_version.h: Move to an interim version. 2011-01-01 Dan Dennedy * Doxyfile, configure, docs/melt.1, src/framework/mlt_version.h: set version to 0.6.0 * src/modules/feeds/NTSC/etv.properties, src/modules/feeds/PAL/etv.properties: Make etv data feeds same and scalable between NTSC and PAL. * demo/mlt_attributes, src/modules/feeds/NTSC/data_fx.properties, src/modules/feeds/NTSC/etv.properties: Make feeds consistent between NTSC and PAL.

The new Producer::pause contains the wait for consumer-sdl-paused. 2010-12-22 Dan Dennedy * src/framework/mlt_frame.c, src/framework/mlt_frame.h: Add mlt_frame_write_ppm to visualize debugging. 2010-12-19 Dan Dennedy * src/modules/sdl/consumer_sdl.c, src/modules/sdl/consumer_sdl_preview.c: Increase the speed of switching between sdl_still and sdl. Based on patch from Jonathan Thomas. It does this by not calling the SDL_InitSubSystem( SDL_INIT_AUDIO ) and SDL_QuitSubSystem( SDL_INIT_AUDIO ) methods every time it switches, but rather when the SDL Preview consumer is started and stopped. 2010-12-16 Dan Dennedy * src/framework/Makefile, src/framework/mlt.h, src/framework/mlt_version.c, src/framework/mlt_version.h, src/swig/mlt.i: Add mlt_version API. Contributed by Jonathan Thomas. 2010-12-15 Dan Dennedy * src/mlt++/MltProducer.cpp, src/modules/sdl/consumer_sdl_preview.c: Synchronize Producer.set_speed(0) with sdl_preview. This also helps prevent deadlock while waiting for consumer-sdl-paused event. Not 100% yet, but 100% requires script (swig) apps to handle the event asynchronously via an event listener, which is not available yet for most - only ruby. Furthermore, they would really like to be able to pass opaque data to the asynchronous handler, which is not yet available in the framework. A good example here is pausing playback prior to seeking to a specific frame. The app should be able to make a consumer-paused event handler to which it can pass the new position, so it can properly seek after the pause has officially occurred. Without the ability to pass opaque data, it must save the new position as an instance variable to use within the handler - once it has support for event listeners that is. 2010-12-09 Dan Dennedy * src/mlt++/MltProperties.cpp, src/mlt++/MltProperties.h: Added Mlt::Properties::wait_for(string). * src/framework/mlt_log.c, src/melt/melt.c, src/modules/avformat/consumer_avformat.c: Add consumer-fatal-error event to avformat consumer. This addresses Kdenlive bug 1894. When the avformat consumer has a fatal error, it will fire an event. Melt intercepts the event and exits with failure. 2010-12-08 Dan Dennedy * configure, src/framework/mlt_consumer.c, src/framework/mlt_consumer.h, src/framework/mlt_types.h, src/melt/melt.c, src/mlt++/MltConsumer.cpp, src/mlt++/MltConsumer.h: Add mlt_consumer_position (Mlt::Consumer::position). 2010-11-30 Dan Dennedy * demo/mlt_swf_variables, demo/txtField.swf: Add example of using SWF with variables. 2010-11-07 Dan Dennedy * src/modules/core/loader.dict, src/modules/swfdec/Makefile, src/modules/swfdec/producer_swfdec.c: Add swfdec producer. No audio or variables/parameters yet. 2010-11-06 Dan Dennedy * src/modules/decklink/DeckLinkAPI.h, src/modules/decklink/DeckLinkAPIDispatch.cpp, src/modules/decklink/LinuxCOM.h, src/modules/decklink/Makefile, src/modules/decklink/consumer_decklink.cpp: Add Blackmagic Design DeckLink consumer. 2010-10-20 Dan Dennedy * src/framework/mlt_tokeniser.c, src/modules/frei0r/frei0r_helper.c: Add support for frei0r string parameter. 2010-10-17 j-b-m * src/modules/qimage/kdenlivetitle_wrapper.cpp, src/modules/qimage/producer_kdenlivetitle.c: Fix serializing xmldata in kdenlivetitle (kdenlive-1841). Patch below fixes an issue with the kdenlivetitle producer. Basically, the problem was that when loading a kdenlivetitle from a file, all the properties were serialized and passed to the xml consumer. The problem became more obvious with the "embeded" images in titles, which then caused images to be embedded inside the kdenlive project file, causing problems like reported in this issue: http://kdenlive.org/mantis/view.php?id=1841 With the patch, titles loaded from a file will not copy the xmldata. 2010-10-17 Dan Dennedy * src/modules/sdl/consumer_sdl.c, src/modules/sdl/consumer_sdl_audio.c, src/modules/sdl/consumer_sdl_preview.c, src/modules/sdl/consumer_sdl_still.c: Fix including SDL headers (3087522). 2010-10-13 Dan Dennedy * src/melt/melt.c, src/modules/avformat/producer_avformat.c: Add colorspace to auto-profile. * src/modules/xml/consumer_xml.c, src/modules/xml/producer_xml.c: (De)serialize colorspace in profile. * src/modules/avformat/consumer_avformat.c, src/modules/avformat/producer_avformat.c: Fix version support for AVCodec:colorspace. 2010-10-07 Dan Dennedy * src/melt/melt.c, src/modules/core/producer_consumer.c, src/modules/core/producer_loader.c, src/modules/melt/producer_melt.c, src/modules/xml/producer_xml.c: Move logic for when to auto-insert consumer producer. Move it into the loader producer so apps other than melt can use it too. To use it, an app must set the profile to explicit. * src/framework/mlt_profile.c, src/framework/mlt_profile.h: Add mlt_profile_clone(). 2010-08-28 Dan Dennedy * src/melt/melt.c, src/modules/melt/producer_melt.c: Add an automatic profile feature to melt. Here are the main use cases this feature provides: - Given a regular (non-mlt-xml) media file, melt reads the media attributes and generates an equivalent MLT profile. This makes it easier to transcode without changing or specifying resolution, aspect, and framerate. - Given a MLT XML file containing a profile attribute or element, melt loads the specified profile. A composition typically contains profile- without you having to remember. - Given a MLT XML containing a profile but also specifying a -profile option, melt automatically uses the 'consumer' producer with the requested profiles. This is similar to the above case, but when explicitly choosing a profile different than the composition one should use the consumer producer. This just makes melt smarter and more automatic. * src/modules/xml/consumer_xml.c, src/modules/xml/mlt-xml.dtd, src/modules/xml/producer_xml.c: Add (de)serialization of profile to XML. In addition to the 'profile' element, one can also set the 'profile' attribute of the root element to a named profile. 2010-10-04 Dan Dennedy * src/modules/avformat/configure, src/modules/avformat/consumer_avformat.c: Add support for short-hand vpre to avformat consumer. For example, when vcodec=libx264, you can use vpre=medium as shorthand for $prefix/share/ffmpeg/libx264-medium.ffpreset. * src/modules/avformat/audioconvert.h, src/modules/avformat/configure, src/modules/avformat/consumer_avformat.c, src/modules/avformat/factory.c, src/modules/avformat/filter_avcolour_space.c, src/modules/avformat/filter_avdeinterlace.c, src/modules/avformat/filter_avresample.c, src/modules/avformat/filter_swscale.c, src/modules/avformat/producer_avformat.c, src/modules/avformat/vdpau.c: FFmpeg build improvements (3078007). Handle --avformat-svn-version=0.5. Fix building without swscale. Fix compiling new colorspace stuff against FFmpeg <= v0.5. FFmpeg libs are increasing; only support contemporary header layout. 2010-09-28 Dan Dennedy * src/modules/sdl/consumer_sdl.c, src/modules/sdl/consumer_sdl_audio.c, src/modules/sdl/consumer_sdl_preview.c, src/modules/sdl/consumer_sdl_still.c: Fix race conditions in SDL (kdenlive-1711). Contributed patch by 'jem' - thanks! 2010-09-26 Dan Dennedy * src/modules/avformat/filter_avcolour_space.c, src/modules/avformat/producer_avformat.c: Set default colorspace (from profile) on frames.

Frame property "force_full_luma" controls this and can be set via producer property "set.force_full_luma." However, it is not really ready for use until libswscale can respect its full_range parameter in a RGB to YUV conversion. 2010-09-13 Dan Dennedy * src/modules/avformat/filter_avcolour_space.c, src/modules/avformat/producer_avformat.c: Rename yuv_std to colorspace. 2010-08-24 Dan Dennedy * src/framework/mlt_profile.h, src/modules/avformat/filter_avcolour_space.c, src/modules/avformat/producer_avformat.c: Add input YUV colorspace (601 vs 709) handling. Still need to work on the output side including normalization and setting the encoder. * src/framework/mlt_frame.c, src/framework/mlt_types.h, src/modules/avformat/filter_avcolour_space.c, src/modules/avformat/filter_swscale.c, src/modules/gtk2/producer_pixbuf.c, src/modules/qimage/producer_qimage.c, src/modules/sdl/producer_sdl_image.c: Revert new image types. I think we can just use frame properties. * src/modules/avformat/filter_avcolour_space.c, src/modules/avformat/producer_avformat.c: Get initial skipping of luma scaling to work. When the avformat producer property skip_luma_scale is set to 1, then we do not scale the luma on the first YCbCr to RGB conversion. This is only done once because swscale always downscales luma when converting RGB to YCbCr, and we need to keep the conversions symmetrical to prevent luma contraction (loss of contrast). 2010-08-23 Dan Dennedy * src/framework/mlt_frame.c, src/framework/mlt_profile.h, src/framework/mlt_types.h, src/modules/avformat/filter_avcolour_space.c, src/modules/avformat/filter_swscale.c, src/modules/avformat/producer_avformat.c, src/modules/gtk2/producer_pixbuf.c, src/modules/qimage/producer_qimage.c, src/modules/sdl/producer_sdl_image.c: Improve colorspace handling (work in progress) Trying to add support for non-scaling luma between YCbCr and RGB conversions as well as support for ITU Rec. 709 luma conversion for HD formats. 2010-09-13 Dan Dennedy * Doxyfile, configure, docs/melt.1, src/framework/mlt.h: Set version to 0.5.10. 2010-09-12 Dan Dennedy * configure, src/modules/core/producer_loader.c: Enable filter avcolor_space on OS X. It works now! * Doxyfile, NEWS, configure, docs/melt.1, src/framework/mlt.h: Set version to 0.5.8. * src/modules/avformat/filter_avcolour_space.c, src/modules/core/filter_imageconvert.c: Enhance image conversion logging. 2010-09-10 Dan Dennedy * src/modules/core/filter_crop.c, src/modules/core/filter_resize.c: Validate alpha channel size before cropping and padding it. Eventually, I need to add mlt_frame_get_alpha() that returns a size and mlt_frame_set_alpha() encapsulates handling of the alpha channel. 2010-09-07 Dan Dennedy * src/modules/avformat/consumer_avformat.c, src/modules/avformat/filter_avcolour_space.c, src/modules/avformat/filter_swscale.c, src/modules/avformat/producer_avformat.c: Revert 3a419b4 (Use caching for swscale contexts). This was just making it too unstable (bug 3060324). 2010-09-05 Dan Dennedy * src/modules/avformat/filter_avcolour_space.c, src/modules/core/filter_imageconvert.c: Apply alpha on frame to rgba image (kdenlive-1786). 2010-08-22 Dan Dennedy * src/modules/avformat/consumer_avformat.c, src/modules/avformat/filter_avcolour_space.c, src/modules/avformat/filter_swscale.c, src/modules/avformat/producer_avformat.c: Use caching for swscale contexts. 2010-08-21 Dan Dennedy * src/modules/avformat/consumer_avformat.c, src/modules/avformat/filter_avcolour_space.c, src/modules/avformat/filter_swscale.c, src/modules/avformat/producer_avformat.c: Enable swscale CPU flags. For FFmpeg builds that use runtime CPU detection. This should make things faster and it seems to be same quality as C routines. * demo/mlt_slideshow2, src/modules/core/filter_luma.c: Enhance luma filter to work with animated filters. Previously, in a slideshow the luma filter would apply the dissolve or wipe repeatedly over a slide. For example, with a slide duration of 75 frames and a luma period of 25 (expressed as 24), the wipe occurs 3 times. However, since the slides were static, you did not notice it until the transition at the beginning of a new slide - when you do want to see it. However, upon adding an affine filter to animate a smooth pan/zoom, you do notice the extra repetitions - the slides appear to blend with one another when they are not transitioning. This change fixes that with new properties 'cycle' and 'duration'. Cycle is basically a replacement for 'period' that fixes the semantics to properly represent a duration. Where you would previously express, for example, period=24, you now say cycle=25. The 'duration' property prevents the repeating and expresses that the transition should only occur within the first N frames of the cycle. See demo/mlt_slideshow2 for an example of using it in conjunction with the affine filter! 2010-08-20 Dan Dennedy * src/modules/gtk2/producer_pixbuf.c, src/modules/qimage/qimage_wrapper.cpp: Fix distorted frame in slideshow transitions. Applies to the .all.ext slideshow approach. May also apply to image sequences with mixed resolutions. 2010-08-19 Dan Dennedy * src/modules/core/Makefile, src/modules/core/factory.c, src/modules/core/filter_audiowave.c: Add audiowave filter. This replaces the video with the audio waveform. Currently, it only works on producers that also provide video. 2010-08-18 Dan Dennedy * src/framework/mlt_frame.c, src/swig/mlt.i, src/swig/python/waveforms.py: Fix waveform generation. It was not obtaining a valid fps. Also, changed rendering to something more expected - negative as negative and channels stacked. Also, add a Python binding to this call to return 8-bit grayscale image as a Python string. Finally, add a Python example. 2010-08-16 Dan Dennedy * src/modules/core/Makefile, src/modules/core/factory.c, src/modules/core/filter_panner.c: Add a panning filter. This does a simple left/right balance when channel=-1 (default). When channel >= 0, you can adjust an individual channel's left/right position. Whereas the simple balance will not cause one channel to appear in another channel, the individual channel does. The start/end properties are floats in the range [-1.0, 1.0]. A start property alone makes it constant over the duration of the filter. There is some handling for more than 2 channels by providing front/rear fade and ganging (balance front and rear together or fade left and right together). 2010-08-15 Dan Dennedy * src/modules/core/factory.c, src/modules/core/filter_channelcopy.c: Add filter channelswap. It is a permutation of channelcopy that can be used from channelcopy as well by setting swap=1. 2010-08-14 Dan Dennedy * src/modules/avformat/consumer_avformat.c, src/modules/avformat/filter_avcolour_space.c, src/modules/avformat/filter_swscale.c, src/modules/avformat/producer_avformat.c: Improve quality of libswscale conversions and scaling. 2010-08-12 Dan Dennedy * src/framework/mlt_frame.h, src/modules/core/filter_imageconvert.c, src/modules/core/producer_colour.c, src/modules/vmfx/filter_chroma.c, src/modules/vmfx/filter_chroma_hold.c: Cleanup existing native color space conversions. This change clarifies that the existing conversions are according to the ITU 601 standard and scaled to and from full gamut RGB. Also, adjust 2 coefficients according to Charles Poynton's matrices. This does not yet attempt to make any substantial improvements. Finally, it replaces the verbose logic and redundancy in the image conversion routine with a concise function dispatch table. 2010-08-08 Dan Dennedy * src/modules/gtk2/producer_pixbuf.c, src/modules/qimage/qimage_wrapper.cpp: Make libexif include compatible with more systems/versions. 2010-08-07 Dan Dennedy * src/modules/core/transition_luma.c, src/modules/frei0r/transition_frei0r.c, src/modules/plus/transition_affine.c: Fix scaling method on B frames of some transitions. 2010-08-04 Dan Dennedy * src/modules/avformat/consumer_avformat.c, src/modules/dv/consumer_libdv.c, src/modules/linsys/consumer_SDIstream.c, src/modules/sdl/consumer_sdl.c, src/modules/sdl/consumer_sdl_still.c: Move firing consumer-frame-show to after done with image. 2010-07-29 j-b-m * src/modules/gtk2/producer_pixbuf.c, src/modules/qimage/qimage_wrapper.cpp: Cleanup & fix memleak modified: gtk2/producer_pixbuf.c modified: qimage/qimage_wrapper.cpp 2010-07-28 j-b-m * src/modules/gtk2/Makefile, src/modules/gtk2/configure, src/modules/gtk2/producer_pixbuf.c, src/modules/qimage/Makefile, src/modules/qimage/configure, src/modules/qimage/qimage_wrapper.cpp, src/modules/qimage/readexif.h: Use libexif to read exif orientation in images modified: src/modules/gtk2/Makefile modified: src/modules/gtk2/configure modified: src/modules/gtk2/producer_pixbuf.c modified: src/modules/qimage/Makefile modified: src/modules/qimage/configure modified: src/modules/qimage/qimage_wrapper.cpp deleted: src/modules/qimage/readexif.h 2010-07-27 j-b-m * src/modules/gtk2/producer_pixbuf.c, src/modules/qimage/qimage_wrapper.cpp, src/modules/qimage/readexif.h: Read EXIF info inside MLT, based on jpegexiforient modified: src/modules/gtk2/producer_pixbuf.c modified: src/modules/qimage/qimage_wrapper.cpp new file: src/modules/qimage/readexif.h 2010-07-20 j-b-m * src/modules/gtk2/producer_pixbuf.c, src/modules/qimage/qimage_wrapper.cpp: Fix exif rotation angle modified: src/modules/gtk2/producer_pixbuf.c modified: src/modules/qimage/qimage_wrapper.cpp 2010-07-14 Dan Dennedy * configure, src/modules/avformat/producer_avformat.c: Fix crash when repeating frames after failure to decode video. 2010-06-20 Dan Dennedy * Doxyfile, configure, docs/melt.1, src/framework/mlt.h: Set version to 0.5.6. * src/modules/avformat/Makefile, src/modules/avformat/configure, src/modules/avformat/factory.c: Fixup local ffmpeg build.

Some early revisions of 0.7.1 would cause garbage on last column of image with non-even width. 2010-04-08 Dan Dennedy * src/swig/configure, src/swig/csharp/build, src/swig/csharp/play.cs, src/swig/csharp/play.sh: Add C# bindings. Thank you to Steeve Descarpentries for the initial contribution. 2010-04-07 Dan Dennedy * src/modules/linsys/consumer_SDIstream.c, src/modules/linsys/sdi_generator.c, src/modules/linsys/sdi_generator.h: Add automatic driver configuration to sdi consumer. This uses the MLT profile to determine the configuration values: video buffer size, audio buffer size, video frame mode (resolution, frame rate), video data mode (8 bit or v210), number of audio channels, audio sampling rate, audio sample size. It does _not_ set the clock source or the number of buffers for audio and video. 2010-03-10 Dan Dennedy * Doxyfile, configure, docs/melt.1, src/framework/mlt.h: Set version to 0.5.2. * src/modules/linsys/consumer_SDIstream.c, src/modules/linsys/sdi_generator.c, src/modules/linsys/sdi_generator.h: Improve performance of sdi consumer (patch from BCE). consumer_SDIstream.c - convertYCBCRtoRGB: different calculation sdi_generator.h - SDIAUDIO transmitter event definitions sdi_generator.c - pack changed to pack8 instead of packv210 - Transmitter events are checked only once a frame - create_HD_SDI_Line and create_SD_SDI_Line do not calculate the current position in the video_buffer for each sample. Now it is done once a line. * src/mlt++/Makefile, src/mlt++/MltFilteredProducer.cpp, src/mlt++/MltFilteredProducer.h: Fix MltFilteredProducer not building. 2010-02-28 Dan Dennedy * src/modules/avformat/filter_avcolour_space.c, src/modules/avformat/filter_swscale.c, src/modules/core/producer_loader.c: Add resolution as init arg to libswscale filters. * src/framework/mlt_frame.c, src/modules/effectv/filter_burn.c: Fix a couple of compile warnings. 2010-02-25 Dan Dennedy * src/modules/avformat/filter_avcolour_space.c, src/modules/core/producer_loader.c: Make FFmpeg the primary image converter if available. Except on OS X. 2010-02-24 Dan Dennedy * src/modules/xine/Makefile, src/modules/xine/yadif.c: Fix build on --disable-sse(2) or non-sse(2) architectures. 2010-02-22 Dan Dennedy * configure, src/modules/sdl/consumer_sdl_preview.c: Fix video glitches when switching still and normal sdl consumers. 2010-02-15 Dan Dennedy * Doxyfile, configure, docs/melt.1, src/framework/mlt.h: Set version to 0.5.0. * NEWS, src/modules/avformat/configure: Add v0.5.0 release notes. 2010-02-11 Dan Dennedy * src/modules/linsys/consumer_SDIstream.c, src/modules/linsys/sdi_generator.c, src/modules/linsys/sdi_generator.h: Add HD-SDI support to Linsys SDI module. This has only been tested with the VidPort. At this time, you must run the linsys sdiaudiocfg and sdivideocfg utilities to configure your card. In time, we hope to remove this step. * src/modules/linsys/Makefile, src/modules/linsys/configure: Add --linsys-with-jpeg configure option. 2010-02-10 Dan Dennedy * profiles/atsc_1080i_50, profiles/atsc_1080i_5994, profiles/atsc_1080i_60, profiles/atsc_1080p_2398, profiles/atsc_1080p_24, profiles/atsc_1080p_25, profiles/atsc_1080p_2997, profiles/atsc_1080p_30, profiles/atsc_720p_2398, profiles/atsc_720p_24, profiles/atsc_720p_25, profiles/atsc_720p_2997, profiles/atsc_720p_30, profiles/atsc_720p_50, profiles/atsc_720p_5994, profiles/atsc_720p_60, profiles/hdv_1080_25p, profiles/hdv_1080_30p, profiles/hdv_1080_50i, profiles/hdv_1080_60i, profiles/hdv_720_25p, profiles/hdv_720_30p, profiles/hdv_720_50p, profiles/hdv_720_60p, profiles/qcif_15, profiles/quarter_15, profiles/quarter_ntsc, profiles/sdi_486i_5994, src/framework/mlt_profile.c: Revise Hz->fps in profiles and add more ATSC profiles. 2010-02-04 Dan Dennedy * src/modules/sdl/consumer_sdl.c, src/modules/sdl/consumer_sdl_audio.c, src/modules/sdl/consumer_sdl_preview.c: Default SDL to use the onefield deinterlace filter. The previous default in the deinterlace filter was linearblend. The new default is yadif. However, onefield is faster is gives cleaner results than linearblend where preserving most resolution is not a factor. Since most usess of SDL are applications with preview windows smaller than actual resolution, it makes sense to use onefield by default in the SDL consumers. * src/modules/xine/Makefile, src/modules/xine/deinterlace.h, src/modules/xine/filter_deinterlace.c, src/modules/xine/vf_yadif_template.h, src/modules/xine/yadif.c, src/modules/xine/yadif.h: Add YADIF methods in deinterlace filter. 2010-02-03 Dan Dennedy * src/framework/mlt_frame.h, src/framework/mlt_service.c, src/framework/mlt_service.h: Hide need_previous_next property from serialization. 2010-02-02 Dan Dennedy * src/framework/mlt_filter.h, src/framework/mlt_frame.h, src/framework/mlt_service.c, src/framework/mlt_service.h: Add fetching previous and next frames in producers. This is only enabled when the property need-previous-next is set true on the producer. This also adds firing a service-changed event on the filter when it gets attached so the filter can set this property on the producer to which it is attached. These frame references are set as "previous frame" and "next frame" properties on the current frame. It is also important to note that these frames do not have ANY filters applied to them, which is important for YADIF and telecide filters, which process before all other filters. 2010-01-21 Dan Dennedy * src/modules/avformat/producer_avformat.c, src/modules/avformat/vdpau.c: Let environment variable MLT_NO_VDPAU=1 disable VDPAU. 2010-01-19 Dan Dennedy * src/modules/avformat/configure, src/modules/avformat/factory.c, src/modules/avformat/producer_avformat.c: Add support for libavdevice (v4l/v4l2). Thanks to hints from Volodymyr M. Lisivka. LD_PRELOAD=/usr/lib/libv4l/v4l2convert.so is required to get some formats to work. * src/framework/mlt_frame.c, src/modules/core/filter_rescale.c, src/modules/gtk2/producer_pango.c, src/modules/gtk2/producer_pixbuf.c, src/modules/qimage/producer_qimage.c: Return and handle errors on failure to produce image (kdenlive-1312). 2010-01-16 Dan Dennedy * Doxyfile, src/framework/mlt_frame.c, src/framework/mlt_frame.h, src/framework/mlt_service.h: Add mlt_frame doxygen docs. 2010-01-10 Dan Dennedy * src/modules/avformat/producer_avformat.c, src/modules/xine/filter_deinterlace.c: Fix setting progressive property on repeated frames (kdenlive-1335). 2010-01-06 Marco Gittler * src/modules/oldfilm/filter_oldfilm.c, src/modules/oldfilm/filter_oldfilm.yml: user array with 100 values yml file updated 2009-12-16 Dan Dennedy * src/framework/mlt_service.c, src/framework/mlt_service.h, src/modules/gtk2/producer_pixbuf.c, src/modules/qimage/producer_qimage.c: Add mlt_service_cache_purge and remove purge in mlt_service_close. The avformat producer holds references to cache items within frame objects. This means mlt_service_close can not purge the cache because frames may be closed after the producer. 2009-12-14 Dan Dennedy * configure, src/framework/mlt.h: Bump to unreleased version. * src/modules/sdl/consumer_sdl.c, src/modules/sdl/consumer_sdl_preview.c, src/modules/sdl/consumer_sdl_still.c: Revert a bunch of changes made to SDL for VDPAU. This set of changes conflicted with Kdenlive, which requires two consumers that need to release SDL on stop. Now, VDPAU support does not need SDL as it gets its own X11 Display pointer. * src/modules/avformat/Makefile, src/modules/avformat/configure, src/modules/avformat/vdpau.c: Make VDPAU independent of SDL X11 Display. This prevents VDPAU from crashing on calls to SDL_Quit() and allows it to be used with non-SDL consumers! (Still requires an X11 session.) 2009-12-13 Dan Dennedy * src/modules/avformat/factory.c, src/modules/avformat/producer_avformat.c: Add producer variant avformat-novalidate. The purpose of this is to increase the speed of loading playlists with known good files. Use with care. This assumes a few properties have been set, in particular "length." This was only tested thus far by modifying the output of consumer xml to change mlt_service from "avformat" to "avformat-novalidate". 2009-12-12 Dan Dennedy * src/modules/avformat/producer_avformat.c, src/modules/avformat/vdpau.c: Add cache support to avformat producer. This also includes a change to make VDPAU work on some versions of FFmpeg beyond Sept 15, 2009 (do not know exactly when). * src/framework/mlt_service.c, src/framework/mlt_service.h: Add mlt_service_cache_set_size() to limit the cache size. * src/framework/mlt_cache.c, src/framework/mlt_cache.h: Add mlt_cache_set_size() to limit the amount of caching. 2009-11-28 Dan Dennedy * src/modules/avformat/Makefile, src/modules/avformat/configure, src/modules/avformat/producer_avformat.c, src/modules/avformat/vdpau.c: Add support for decoding H.264 with VDPAU. This applies to all H.264 at the moment unless novdpau=1 is set on the producer. Also, this can only handle up to about 10 - 15 clips using VDPAU in the project at the moment until the avformat producer is changed to use mlt_cache. * src/framework/mlt_consumer.c, src/modules/sdl/consumer_sdl.c, src/modules/sdl/consumer_sdl_preview.c, src/modules/sdl/consumer_sdl_still.c: Make the SDL consumer cooperate with VDPAU. This moves the SDL_Quit calls from the consumer_stop to the consumer_close functions. Also, it exports the X11 Display pointer to the mlt_environment and the global SDL mutex to the consumer class. 2009-12-08 Dan Dennedy * Doxyfile, NEWS, configure, docs/melt.1, src/framework/mlt.h: Set version to 0.4.10 and update release notes. * configure, src/framework/mlt.h, src/modules/avformat/producer_avformat.c: Fix underlinking libm by removing math function. 2009-12-07 Dan Dennedy * Doxyfile, configure, docs/melt.1, src/framework/mlt.h: Set version to 0.4.8. * src/modules/core/loader.ini, src/modules/core/producer_loader.c: Fix some cases image and audio formats not converting (kdenlive-1259). 2009-11-29 Marco Gittler * src/modules/oldfilm/filter_vignette.c, src/modules/oldfilm/filter_vignette.yml: use float for vignette effect fixed also bug in wrong y center * src/modules/oldfilm/filter_vignette.c, src/modules/oldfilm/filter_vignette.yml: use extra paramters for vignette settings 2009-10-10 Dan Dennedy * configure, src/framework/mlt.h: Bump the version to 0.4.7. * src/modules/linsys/consumer_SDIstream.c, src/modules/linsys/sdi_generator.c: Convert some printfs to mlt_log. * src/modules/linsys/consumer_SDIstream.c, src/modules/linsys/sdi_generator.c: Cleanup unused parameters. * src/modules/linsys/consumer_SDIstream.c, src/modules/linsys/sdi_generator.c: Add support for >2 audio channels to Linsys SDI consumer. This does not yet have any remapping support. 2009-10-07 Dan Dennedy * AUTHORS, Doxyfile, NEWS, configure, docs/melt.1, src/framework/mlt.h: Set version to 0.4.6 and update release notes. * src/modules/avformat/Makefile, src/modules/avformat/configure: Add configure option --avformat-svn-version. Also update recommended version to Sept 15, 2009 and other cleanup. 2009-10-04 j-b-m * src/modules/qimage/kdenlivetitle_wrapper.cpp, src/modules/qimage/producer_kdenlivetitle.c: Fix behaviour of title clips when in and out points are given modified: src/modules/qimage/kdenlivetitle_wrapper.cpp modified: src/modules/qimage/producer_kdenlivetitle.c 2009-09-20 Dan Dennedy * src/mlt++/MltField.cpp, src/mlt++/MltField.h, src/mlt++/MltProducer.cpp, src/mlt++/MltProducer.h, src/mlt++/MltProperties.cpp, src/mlt++/MltProperties.h, src/mlt++/MltRepository.cpp, src/mlt++/MltRepository.h, src/mlt++/MltTractor.cpp, src/mlt++/MltTractor.h, src/mlt++/MltTransition.cpp, src/mlt++/MltTransition.h, src/swig/mlt.i: Update bindings. 2009-09-19 Dan Dennedy * src/mlt++/MltProperties.cpp, src/mlt++/MltProperties.h: Add Properties constructor from opaque pointer. 2009-09-15 Dan Dennedy * src/swig/Makefile, src/swig/java/build, src/swig/lua/build, src/swig/perl/build, src/swig/php/build, src/swig/python/build, src/swig/ruby/build, src/swig/tcl/build: Fix distclean make target under swig and cleanup object files. 2009-09-13 Dan Dennedy * src/modules/core/factory.c, src/modules/core/producer_loader.c, src/modules/kdenlive/producer_framebuffer.c: Invert position of normalization filters with framebuffer producer. Previously, the framebuffer producer loaded a normalized producer, which can give undesired results with things like crop and really any time you want to filter the unpadded images of the speed-altered video. Now, the framebuffer uses the new "abnormal" producer to load the clip without normalization filters and sets appropriate frame properties to allow the normalizing filters attached to the framebuffer to act appropriately. This new abnormal filter is simply an alias to the existing loader filter, which uses the name by which it is invoked to toggle the behaviour of whether to attach normalizing filters. 2009-09-10 Dan Dennedy * Makefile, src/swig/Makefile, src/swig/configure: Improve swig build with help from Michael Forney. 2009-08-26 Dan Dennedy * src/modules/sdl/Makefile, src/modules/sdl/consumer_sdl_audio.c,

= value [value, ...] # For lists items can also be appended using: # TAG += value [value, ...] # Values that contain spaces should be placed between quotes (" ") #--------------------------------------------------------------------------- # Project related configuration options #--------------------------------------------------------------------------- # This tag specifies the encoding used for all characters in the config file # that follow. The default is UTF-8 which is also the encoding used for all # text before the first occurrence of this tag. Doxygen uses libiconv (or the # iconv built into libc) for the transcoding. See # http://www.gnu.org/software/libiconv for the list of possible encodings. DOXYFILE_ENCODING = UTF-8 # The PROJECT_NAME tag is a single word (or a sequence of words surrounded # by quotes) that should identify the project. PROJECT_NAME = MLT # The PROJECT_NUMBER tag can be used to enter a project or revision number. # This could be handy for archiving the generated documentation or # if some version control system is used. PROJECT_NUMBER = 0.9.0 # The OUTPUT_DIRECTORY tag is used to specify the (relative or absolute) # base path where the generated documentation will be put. # If a relative path is entered, it will be relative to the location # where doxygen was started. If left blank the current directory will be used. OUTPUT_DIRECTORY = docs # If the CREATE_SUBDIRS tag is set to YES, then doxygen will create # 4096 sub-directories (in 2 levels) under the output directory of each output # format and will distribute the generated files over these directories. # Enabling this option can be useful when feeding doxygen a huge amount of # source files, where putting all generated files in the same directory would # otherwise cause performance problems for the file system. CREATE_SUBDIRS = NO # The OUTPUT_LANGUAGE tag is used to specify the language in which all # documentation generated by doxygen is written. Doxygen will use this # information to generate all constant output in the proper language. # The default language is English, other supported languages are: # Afrikaans, Arabic, Brazilian, Catalan, Chinese, Chinese-Traditional, # Croatian, Czech, Danish, Dutch, Farsi, Finnish, French, German, Greek, # Hungarian, Italian, Japanese, Japanese-en (Japanese with English messages), # Korean, Korean-en, Lithuanian, Norwegian, Macedonian, Persian, Polish, # Portuguese, Romanian, Russian, Serbian, Serbian-Cyrilic, Slovak, Slovene, # Spanish, Swedish, and Ukrainian. OUTPUT_LANGUAGE = English # If the BRIEF_MEMBER_DESC tag is set to YES (the default) Doxygen will # include brief member descriptions after the members that are listed in # the file and class documentation (similar to JavaDoc). # Set to NO to disable this. BRIEF_MEMBER_DESC = YES # If the REPEAT_BRIEF tag is set to YES (the default) Doxygen will prepend # the brief description of a member or function before the detailed description. # Note: if both HIDE_UNDOC_MEMBERS and BRIEF_MEMBER_DESC are set to NO, the # brief descriptions will be completely suppressed. REPEAT_BRIEF = YES # This tag implements a quasi-intelligent brief description abbreviator # that is used to form the text in various listings. Each string # in this list, if found as the leading text of the brief description, will be # stripped from the text and the result after processing the whole list, is # used as the annotated text. Otherwise, the brief description is used as-is. # If left blank, the following values are used ("$name" is automatically # replaced with the name of the entity): "The $name class" "The $name widget" # "The $name file" "is" "provides" "specifies" "contains" # "represents" "a" "an" "the" ABBREVIATE_BRIEF = # If the ALWAYS_DETAILED_SEC and REPEAT_BRIEF tags are both set to YES then # Doxygen will generate a detailed section even if there is only a brief # description. ALWAYS_DETAILED_SEC = NO # If the INLINE_INHERITED_MEMB tag is set to YES, doxygen will show all # inherited members of a class in the documentation of that class as if those # members were ordinary class members. Constructors, destructors and assignment # operators of the base classes will not be shown.

Preamble The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This General Public License applies to most of the Free Software Foundation's software and to any other program whose authors commit to using it. (Some other Free Software Foundation software is covered by the GNU Library General Public License instead.) You can apply it to your programs, too. When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs; and that you know you can do these things. To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or to ask you to surrender the rights. These restrictions translate to certain responsibilities for you if you distribute copies of the software, or if you modify it. For example, if you distribute copies of such a program, whether gratis or for a fee, you must give the recipients all the rights that you have. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights. We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which gives you legal permission to copy, distribute and/or modify the software. Also, for each author's protection and ours, we want to make certain that everyone understands that there is no warranty for this free software. If the software is modified by someone else and passed on, we want its recipients to know that what they have is not the original, so that any problems introduced by others will not reflect on the original authors' reputations. Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that redistributors of a free program will individually obtain patent licenses, in effect making the program proprietary. To prevent this, we have made it clear that any patent must be licensed for everyone's free use or not licensed at all. The precise terms and conditions for copying, distribution and modification follow. GNU GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. This License applies to any program or other work which contains a notice placed by the copyright holder saying it may be distributed under the terms of this General Public License. The "Program", below, refers to any such program or work, and a "work based on the Program" means either the Program or any derivative work under copyright law: that is to say, a work containing the Program or a portion of it, either verbatim or with modifications and/or translated into another language. (Hereinafter, translation is included without limitation in the term "modification".) Each licensee is addressed as "you". Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running the Program is not restricted, and the output from the Program is covered only if its contents constitute a work based on the Program (independent of having been made by running the Program). Whether that is true depends on what the Program does. 1. You may copy and distribute verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and give any other recipients of the Program a copy of this License along with the Program. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 2. You may modify your copy or copies of the Program or any portion of it, thus forming a work based on the Program, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: a) You must cause the modified files to carry prominent notices stating that you changed the files and the date of any change. b) You must cause any work that you distribute or publish, that in whole or in part contains or is derived from the Program or any part thereof, to be licensed as a whole at no charge to all third parties under the terms of this License. c) If the modified program normally reads commands interactively when run, you must cause it, when started running for such interactive use in the most ordinary way, to print or display an announcement including an appropriate copyright notice and a notice that there is no warranty (or else, saying that you provide a warranty) and that users may redistribute the program under these conditions, and telling the user how to view a copy of this License. (Exception: if the Program itself is interactive but does not normally print such an announcement, your work based on the Program is not required to print an announcement.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Program, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Program, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Program. In addition, mere aggregation of another work not based on the Program with the Program (or with a work based on the Program) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 3. You may copy and distribute the Program (or a work based on it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you also do one of the following: a) Accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, b) Accompany it with a written offer, valid for at least three years, to give any third party, for a charge no more than your cost of physically performing source distribution, a complete machine-readable copy of the corresponding source code, to be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, c) Accompany it with the information you received as to the offer to distribute corresponding source code. (This alternative is allowed only for noncommercial distribution and only if you received the program in object code or executable form with such an offer, in accord with Subsection b above.) The source code for a work means the preferred form of the work for making modifications to it. For an executable work, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the executable. However, as a special exception, the source code distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. If distribution of executable or object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place counts as distribution of the source code, even though third parties are not compelled to copy the source along with the object code. 4. You may not copy, modify, sublicense, or distribute the Program except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense or distribute the Program is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. 5. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Program or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Program (or any work based on the Program), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Program or works based on it. 6. Each time you redistribute the Program (or any work based on the Program), the recipient automatically receives a license from the original licensor to copy, distribute or modify the Program subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties to this License. 7. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Program at all. For example, if a patent license would not permit royalty-free redistribution of the Program by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Program. If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply and the section as a whole is intended to apply in other circumstances. It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system, which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. 8. If the distribution and/or use of the Program is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Program under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. 9. The Free Software Foundation may publish revised and/or new versions of the General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Program specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of this License, you may choose any version ever published by the Free Software Foundation. 10. If you wish to incorporate parts of the Program into other free programs whose distribution conditions are different, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. NO WARRANTY 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. END OF TERMS AND CONDITIONS How to Apply These Terms to Your New Programs If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms. To do so, attach the following notices to the program. It is safest to attach them to the start of each source file to most effectively convey the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found. Copyright (C) This program is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation; either version 2 of the License, or (at your option) any later version. This program is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details. You should have received a copy of the GNU General Public License along with this program; if not, write to the Free Software Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA Also add information on how to contact you by electronic and paper mail. If the program is interactive, make it output a short notice like this when it starts in an interactive mode: Gnomovision version 69, Copyright (C) year name of author Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. This is free software, and you are welcome to redistribute it under certain conditions; type `show c' for details. The hypothetical commands `show w' and `show c' should show the appropriate parts of the General Public License. Of course, the commands you use may be called something other than `show w' and `show c'; they could even be mouse-clicks or menu items--whatever suits your program. You should also get your employer (if you work as a programmer) or your school, if any, to sign a "copyright disclaimer" for the program, if necessary. Here is a sample; alter the names: Yoyodyne, Inc., hereby disclaims all copyright interest in the program `Gnomovision' (which makes passes at compilers) written by James Hacker. , 1 April 1989 Ty Coon, President of Vice This General Public License does not permit incorporating your program into proprietary programs. If your program is a subroutine library, you may consider it more useful to permit linking proprietary applications with the library. If this is what you want to do, use the GNU Library General Public License instead of this License. mlt-0.9.0/GPLv3000066400000000000000000001045131215300731300131310ustar00rootroot00000000000000 GNU GENERAL PUBLIC LICENSE Version 3, 29 June 2007 Copyright (C) 2007 Free Software Foundation, Inc. Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. Preamble The GNU General Public License is a free, copyleft license for software and other kinds of works. The licenses for most software and other practical works are designed to take away your freedom to share and change the works. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change all versions of a program--to make sure it remains free software for all its users. We, the Free Software Foundation, use the GNU General Public License for most of our software; it applies also to any other work released this way by its authors. You can apply it to your programs, too. When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for them if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs, and that you know you can do these things. To protect your rights, we need to prevent others from denying you these rights or asking you to surrender the rights. Therefore, you have certain responsibilities if you distribute copies of the software, or if you modify it: responsibilities to respect the freedom of others. For example, if you distribute copies of such a program, whether gratis or for a fee, you must pass on to the recipients the same freedoms that you received. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights. Developers that use the GNU GPL protect your rights with two steps: (1) assert copyright on the software, and (2) offer you this License giving you legal permission to copy, distribute and/or modify it. For the developers' and authors' protection, the GPL clearly explains that there is no warranty for this free software. For both users' and authors' sake, the GPL requires that modified versions be marked as changed, so that their problems will not be attributed erroneously to authors of previous versions. Some devices are designed to deny users access to install or run modified versions of the software inside them, although the manufacturer can do so. This is fundamentally incompatible with the aim of protecting users' freedom to change the software. The systematic pattern of such abuse occurs in the area of products for individuals to use, which is precisely where it is most unacceptable. Therefore, we have designed this version of the GPL to prohibit the practice for those products. If such problems arise substantially in other domains, we stand ready to extend this provision to those domains in future versions of the GPL, as needed to protect the freedom of users. Finally, every program is threatened constantly by software patents. States should not allow patents to restrict development and use of software on general-purpose computers, but in those that do, we wish to avoid the special danger that patents applied to a free program could make it effectively proprietary. To prevent this, the GPL assures that patents cannot be used to render the program non-free. The precise terms and conditions for copying, distribution and modification follow. TERMS AND CONDITIONS 0. Definitions. "This License" refers to version 3 of the GNU General Public License. "Copyright" also means copyright-like laws that apply to other kinds of works, such as semiconductor masks. "The Program" refers to any copyrightable work licensed under this License. Each licensee is addressed as "you". "Licensees" and "recipients" may be individuals or organizations. To "modify" a work means to copy from or adapt all or part of the work in a fashion requiring copyright permission, other than the making of an exact copy. The resulting work is called a "modified version" of the earlier work or a work "based on" the earlier work. A "covered work" means either the unmodified Program or a work based on the Program. To "propagate" a work means to do anything with it that, without permission, would make you directly or secondarily liable for infringement under applicable copyright law, except executing it on a computer or modifying a private copy. Propagation includes copying, distribution (with or without modification), making available to the public, and in some countries other activities as well. To "convey" a work means any kind of propagation that enables other parties to make or receive copies. Mere interaction with a user through a computer network, with no transfer of a copy, is not conveying. An interactive user interface displays "Appropriate Legal Notices" to the extent that it includes a convenient and prominently visible feature that (1) displays an appropriate copyright notice, and (2) tells the user that there is no warranty for the work (except to the extent that warranties are provided), that licensees may convey the work under this License, and how to view a copy of this License. If the interface presents a list of user commands or options, such as a menu, a prominent item in the list meets this criterion. 1. Source Code. The "source code" for a work means the preferred form of the work for making modifications to it. "Object code" means any non-source form of a work. A "Standard Interface" means an interface that either is an official standard defined by a recognized standards body, or, in the case of interfaces specified for a particular programming language, one that is widely used among developers working in that language. The "System Libraries" of an executable work include anything, other than the work as a whole, that (a) is included in the normal form of packaging a Major Component, but which is not part of that Major Component, and (b) serves only to enable use of the work with that Major Component, or to implement a Standard Interface for which an implementation is available to the public in source code form. A "Major Component", in this context, means a major essential component (kernel, window system, and so on) of the specific operating system (if any) on which the executable work runs, or a compiler used to produce the work, or an object code interpreter used to run it. The "Corresponding Source" for a work in object code form means all the source code needed to generate, install, and (for an executable work) run the object code and to modify the work, including scripts to control those activities. However, it does not include the work's System Libraries, or general-purpose tools or generally available free programs which are used unmodified in performing those activities but which are not part of the work. For example, Corresponding Source includes interface definition files associated with source files for the work, and the source code for shared libraries and dynamically linked subprograms that the work is specifically designed to require, such as by intimate data communication or control flow between those subprograms and other parts of the work. The Corresponding Source need not include anything that users can regenerate automatically from other parts of the Corresponding Source. The Corresponding Source for a work in source code form is that same work. 2. Basic Permissions. All rights granted under this License are granted for the term of copyright on the Program, and are irrevocable provided the stated conditions are met. This License explicitly affirms your unlimited permission to run the unmodified Program. The output from running a covered work is covered by this License only if the output, given its content, constitutes a covered work. This License acknowledges your rights of fair use or other equivalent, as provided by copyright law. You may make, run and propagate covered works that you do not convey, without conditions so long as your license otherwise remains in force. You may convey covered works to others for the sole purpose of having them make modifications exclusively for you, or provide you with facilities for running those works, provided that you comply with the terms of this License in conveying all material for which you do not control copyright. Those thus making or running the covered works for you must do so exclusively on your behalf, under your direction and control, on terms that prohibit them from making any copies of your copyrighted material outside their relationship with you. Conveying under any other circumstances is permitted solely under the conditions stated below. Sublicensing is not allowed; section 10 makes it unnecessary. 3. Protecting Users' Legal Rights From Anti-Circumvention Law. No covered work shall be deemed part of an effective technological measure under any applicable law fulfilling obligations under article 11 of the WIPO copyright treaty adopted on 20 December 1996, or similar laws prohibiting or restricting circumvention of such measures. When you convey a covered work, you waive any legal power to forbid circumvention of technological measures to the extent such circumvention is effected by exercising rights under this License with respect to the covered work, and you disclaim any intention to limit operation or modification of the work as a means of enforcing, against the work's users, your or third parties' legal rights to forbid circumvention of technological measures. 4. Conveying Verbatim Copies. You may convey verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice; keep intact all notices stating that this License and any non-permissive terms added in accord with section 7 apply to the code; keep intact all notices of the absence of any warranty; and give all recipients a copy of this License along with the Program. You may charge any price or no price for each copy that you convey, and you may offer support or warranty protection for a fee. 5. Conveying Modified Source Versions. You may convey a work based on the Program, or the modifications to produce it from the Program, in the form of source code under the terms of section 4, provided that you also meet all of these conditions: a) The work must carry prominent notices stating that you modified it, and giving a relevant date. b) The work must carry prominent notices stating that it is released under this License and any conditions added under section 7. This requirement modifies the requirement in section 4 to "keep intact all notices". c) You must license the entire work, as a whole, under this License to anyone who comes into possession of a copy. This License will therefore apply, along with any applicable section 7 additional terms, to the whole of the work, and all its parts, regardless of how they are packaged. This License gives no permission to license the work in any other way, but it does not invalidate such permission if you have separately received it. d) If the work has interactive user interfaces, each must display Appropriate Legal Notices; however, if the Program has interactive interfaces that do not display Appropriate Legal Notices, your work need not make them do so. A compilation of a covered work with other separate and independent works, which are not by their nature extensions of the covered work, and which are not combined with it such as to form a larger program, in or on a volume of a storage or distribution medium, is called an "aggregate" if the compilation and its resulting copyright are not used to limit the access or legal rights of the compilation's users beyond what the individual works permit. Inclusion of a covered work in an aggregate does not cause this License to apply to the other parts of the aggregate. 6. Conveying Non-Source Forms. You may convey a covered work in object code form under the terms of sections 4 and 5, provided that you also convey the machine-readable Corresponding Source under the terms of this License, in one of these ways: a) Convey the object code in, or embodied in, a physical product (including a physical distribution medium), accompanied by the Corresponding Source fixed on a durable physical medium customarily used for software interchange. b) Convey the object code in, or embodied in, a physical product (including a physical distribution medium), accompanied by a written offer, valid for at least three years and valid for as long as you offer spare parts or customer support for that product model, to give anyone who possesses the object code either (1) a copy of the Corresponding Source for all the software in the product that is covered by this License, on a durable physical medium customarily used for software interchange, for a price no more than your reasonable cost of physically performing this conveying of source, or (2) access to copy the Corresponding Source from a network server at no charge. c) Convey individual copies of the object code with a copy of the written offer to provide the Corresponding Source. This alternative is allowed only occasionally and noncommercially, and only if you received the object code with such an offer, in accord with subsection 6b. d) Convey the object code by offering access from a designated place (gratis or for a charge), and offer equivalent access to the Corresponding Source in the same way through the same place at no further charge. You need not require recipients to copy the Corresponding Source along with the object code. If the place to copy the object code is a network server, the Corresponding Source may be on a different server (operated by you or a third party) that supports equivalent copying facilities, provided you maintain clear directions next to the object code saying where to find the Corresponding Source. Regardless of what server hosts the Corresponding Source, you remain obligated to ensure that it is available for as long as needed to satisfy these requirements. e) Convey the object code using peer-to-peer transmission, provided you inform other peers where the object code and Corresponding Source of the work are being offered to the general public at no charge under subsection 6d. A separable portion of the object code, whose source code is excluded from the Corresponding Source as a System Library, need not be included in conveying the object code work. A "User Product" is either (1) a "consumer product", which means any tangible personal property which is normally used for personal, family, or household purposes, or (2) anything designed or sold for incorporation into a dwelling. In determining whether a product is a consumer product, doubtful cases shall be resolved in favor of coverage. For a particular product received by a particular user, "normally used" refers to a typical or common use of that class of product, regardless of the status of the particular user or of the way in which the particular user actually uses, or expects or is expected to use, the product. A product is a consumer product regardless of whether the product has substantial commercial, industrial or non-consumer uses, unless such uses represent the only significant mode of use of the product. "Installation Information" for a User Product means any methods, procedures, authorization keys, or other information required to install and execute modified versions of a covered work in that User Product from a modified version of its Corresponding Source. The information must suffice to ensure that the continued functioning of the modified object code is in no case prevented or interfered with solely because modification has been made. If you convey an object code work under this section in, or with, or specifically for use in, a User Product, and the conveying occurs as part of a transaction in which the right of possession and use of the User Product is transferred to the recipient in perpetuity or for a fixed term (regardless of how the transaction is characterized), the Corresponding Source conveyed under this section must be accompanied by the Installation Information. But this requirement does not apply if neither you nor any third party retains the ability to install modified object code on the User Product (for example, the work has been installed in ROM). The requirement to provide Installation Information does not include a requirement to continue to provide support service, warranty, or updates for a work that has been modified or installed by the recipient, or for the User Product in which it has been modified or installed. Access to a network may be denied when the modification itself materially and adversely affects the operation of the network or violates the rules and protocols for communication across the network. Corresponding Source conveyed, and Installation Information provided, in accord with this section must be in a format that is publicly documented (and with an implementation available to the public in source code form), and must require no special password or key for unpacking, reading or copying. 7. Additional Terms. "Additional permissions" are terms that supplement the terms of this License by making exceptions from one or more of its conditions. Additional permissions that are applicable to the entire Program shall be treated as though they were included in this License, to the extent that they are valid under applicable law. If additional permissions apply only to part of the Program, that part may be used separately under those permissions, but the entire Program remains governed by this License without regard to the additional permissions. When you convey a copy of a covered work, you may at your option remove any additional permissions from that copy, or from any part of it. (Additional permissions may be written to require their own removal in certain cases when you modify the work.) You may place additional permissions on material, added by you to a covered work, for which you have or can give appropriate copyright permission. Notwithstanding any other provision of this License, for material you add to a covered work, you may (if authorized by the copyright holders of that material) supplement the terms of this License with terms: a) Disclaiming warranty or limiting liability differently from the terms of sections 15 and 16 of this License; or b) Requiring preservation of specified reasonable legal notices or author attributions in that material or in the Appropriate Legal Notices displayed by works containing it; or c) Prohibiting misrepresentation of the origin of that material, or requiring that modified versions of such material be marked in reasonable ways as different from the original version; or d) Limiting the use for publicity purposes of names of licensors or authors of the material; or e) Declining to grant rights under trademark law for use of some trade names, trademarks, or service marks; or f) Requiring indemnification of licensors and authors of that material by anyone who conveys the material (or modified versions of it) with contractual assumptions of liability to the recipient, for any liability that these contractual assumptions directly impose on those licensors and authors. All other non-permissive additional terms are considered "further restrictions" within the meaning of section 10. If the Program as you received it, or any part of it, contains a notice stating that it is governed by this License along with a term that is a further restriction, you may remove that term. If a license document contains a further restriction but permits relicensing or conveying under this License, you may add to a covered work material governed by the terms of that license document, provided that the further restriction does not survive such relicensing or conveying. If you add terms to a covered work in accord with this section, you must place, in the relevant source files, a statement of the additional terms that apply to those files, or a notice indicating where to find the applicable terms. Additional terms, permissive or non-permissive, may be stated in the form of a separately written license, or stated as exceptions; the above requirements apply either way. 8. Termination. You may not propagate or modify a covered work except as expressly provided under this License. Any attempt otherwise to propagate or modify it is void, and will automatically terminate your rights under this License (including any patent licenses granted under the third paragraph of section 11). However, if you cease all violation of this License, then your license from a particular copyright holder is reinstated (a) provisionally, unless and until the copyright holder explicitly and finally terminates your license, and (b) permanently, if the copyright holder fails to notify you of the violation by some reasonable means prior to 60 days after the cessation. Moreover, your license from a particular copyright holder is reinstated permanently if the copyright holder notifies you of the violation by some reasonable means, this is the first time you have received notice of violation of this License (for any work) from that copyright holder, and you cure the violation prior to 30 days after your receipt of the notice. Termination of your rights under this section does not terminate the licenses of parties who have received copies or rights from you under this License. If your rights have been terminated and not permanently reinstated, you do not qualify to receive new licenses for the same material under section 10. 9. Acceptance Not Required for Having Copies. You are not required to accept this License in order to receive or run a copy of the Program. Ancillary propagation of a covered work occurring solely as a consequence of using peer-to-peer transmission to receive a copy likewise does not require acceptance. However, nothing other than this License grants you permission to propagate or modify any covered work. These actions infringe copyright if you do not accept this License. Therefore, by modifying or propagating a covered work, you indicate your acceptance of this License to do so. 10. Automatic Licensing of Downstream Recipients. Each time you convey a covered work, the recipient automatically receives a license from the original licensors, to run, modify and propagate that work, subject to this License. You are not responsible for enforcing compliance by third parties with this License. An "entity transaction" is a transaction transferring control of an organization, or substantially all assets of one, or subdividing an organization, or merging organizations. If propagation of a covered work results from an entity transaction, each party to that transaction who receives a copy of the work also receives whatever licenses to the work the party's predecessor in interest had or could give under the previous paragraph, plus a right to possession of the Corresponding Source of the work from the predecessor in interest, if the predecessor has it or can get it with reasonable efforts. You may not impose any further restrictions on the exercise of the rights granted or affirmed under this License. For example, you may not impose a license fee, royalty, or other charge for exercise of rights granted under this License, and you may not initiate litigation (including a cross-claim or counterclaim in a lawsuit) alleging that any patent claim is infringed by making, using, selling, offering for sale, or importing the Program or any portion of it. 11. Patents. A "contributor" is a copyright holder who authorizes use under this License of the Program or a work on which the Program is based. The work thus licensed is called the contributor's "contributor version". A contributor's "essential patent claims" are all patent claims owned or controlled by the contributor, whether already acquired or hereafter acquired, that would be infringed by some manner, permitted by this License, of making, using, or selling its contributor version, but do not include claims that would be infringed only as a consequence of further modification of the contributor version. For purposes of this definition, "control" includes the right to grant patent sublicenses in a manner consistent with the requirements of this License. Each contributor grants you a non-exclusive, worldwide, royalty-free patent license under the contributor's essential patent claims, to make, use, sell, offer for sale, import and otherwise run, modify and propagate the contents of its contributor version. In the following three paragraphs, a "patent license" is any express agreement or commitment, however denominated, not to enforce a patent (such as an express permission to practice a patent or covenant not to sue for patent infringement). To "grant" such a patent license to a party means to make such an agreement or commitment not to enforce a patent against the party. If you convey a covered work, knowingly relying on a patent license, and the Corresponding Source of the work is not available for anyone to copy, free of charge and under the terms of this License, through a publicly available network server or other readily accessible means, then you must either (1) cause the Corresponding Source to be so available, or (2) arrange to deprive yourself of the benefit of the patent license for this particular work, or (3) arrange, in a manner consistent with the requirements of this License, to extend the patent license to downstream recipients. "Knowingly relying" means you have actual knowledge that, but for the patent license, your conveying the covered work in a country, or your recipient's use of the covered work in a country, would infringe one or more identifiable patents in that country that you have reason to believe are valid. If, pursuant to or in connection with a single transaction or arrangement, you convey, or propagate by procuring conveyance of, a covered work, and grant a patent license to some of the parties receiving the covered work authorizing them to use, propagate, modify or convey a specific copy of the covered work, then the patent license you grant is automatically extended to all recipients of the covered work and works based on it. A patent license is "discriminatory" if it does not include within the scope of its coverage, prohibits the exercise of, or is conditioned on the non-exercise of one or more of the rights that are specifically granted under this License. You may not convey a covered work if you are a party to an arrangement with a third party that is in the business of distributing software, under which you make payment to the third party based on the extent of your activity of conveying the work, and under which the third party grants, to any of the parties who would receive the covered work from you, a discriminatory patent license (a) in connection with copies of the covered work conveyed by you (or copies made from those copies), or (b) primarily for and in connection with specific products or compilations that contain the covered work, unless you entered into that arrangement, or that patent license was granted, prior to 28 March 2007. Nothing in this License shall be construed as excluding or limiting any implied license or other defenses to infringement that may otherwise be available to you under applicable patent law. 12. No Surrender of Others' Freedom. If conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot convey a covered work so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not convey it at all. For example, if you agree to terms that obligate you to collect a royalty for further conveying from those to whom you convey the Program, the only way you could satisfy both those terms and this License would be to refrain entirely from conveying the Program. 13. Use with the GNU Affero General Public License. Notwithstanding any other provision of this License, you have permission to link or combine any covered work with a work licensed under version 3 of the GNU Affero General Public License into a single combined work, and to convey the resulting work. The terms of this License will continue to apply to the part which is the covered work, but the special requirements of the GNU Affero General Public License, section 13, concerning interaction through a network will apply to the combination as such. 14. Revised Versions of this License. The Free Software Foundation may publish revised and/or new versions of the GNU General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Program specifies that a certain numbered version of the GNU General Public License "or any later version" applies to it, you have the option of following the terms and conditions either of that numbered version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of the GNU General Public License, you may choose any version ever published by the Free Software Foundation. If the Program specifies that a proxy can decide which future versions of the GNU General Public License can be used, that proxy's public statement of acceptance of a version permanently authorizes you to choose that version for the Program. Later license versions may give you additional or different permissions. However, no additional obligations are imposed on any author or copyright holder as a result of your choosing to follow a later version. 15. Disclaimer of Warranty. THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 16. Limitation of Liability. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. 17. Interpretation of Sections 15 and 16. If the disclaimer of warranty and limitation of liability provided above cannot be given local legal effect according to their terms, reviewing courts shall apply local law that most closely approximates an absolute waiver of all civil liability in connection with the Program, unless a warranty or assumption of liability accompanies a copy of the Program in return for a fee. END OF TERMS AND CONDITIONS How to Apply These Terms to Your New Programs If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms. To do so, attach the following notices to the program. It is safest to attach them to the start of each source file to most effectively state the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found. Copyright (C) This program is free software: you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation, either version 3 of the License, or (at your option) any later version. This program is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details. You should have received a copy of the GNU General Public License along with this program. If not, see . Also add information on how to contact you by electronic and paper mail. If the program does terminal interaction, make it output a short notice like this when it starts in an interactive mode: Copyright (C) This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'. This is free software, and you are welcome to redistribute it under certain conditions; type `show c' for details. The hypothetical commands `show w' and `show c' should show the appropriate parts of the General Public License. Of course, your program's commands might be different; for a GUI interface, you would use an "about box". You should also get your employer (if you work as a programmer) or school, if any, to sign a "copyright disclaimer" for the program, if necessary. For more information on this, and how to apply and follow the GNU GPL, see . The GNU General Public License does not permit incorporating your program into proprietary programs.

Special thanks to Mikko Rapeli who provided many of the Coverity fixes. Version 0.8.0 - June 1, 2012 The minor version is increased due to the addition of time properties! The soname version increased in the process because some mlt_property functions changed; however, very few if any apps actually directly use mlt_property preferring to use mlt_properties instead. In addition: * improve seek speed on AVCHD when using FFmpeg v0.9.1+ (NOT Libav!) * composite and dissolve speed improvements on x86-64 * improve performance of caching in image producers * add device enumeration to decklink producer and consumer Special thanks go to contributors Maksym Veremeyenko and Ed Rogalsky.

Since FFmpeg forked and there were a few releases, there is no recommended version at this time. With that said, there were changes to accomodate the API changes with some moderate testing of the 0.6, 0.7, and 0.8 series releases of both FFmpeg and Libav. Version 0.7.2 - May 1, 2011 This is a minor release to fix a few things between the 0.7.0 release and the release of Kdenlive 0.8. I recommend Kdenlive v0.8 users to upgrade to this version of Mlt. Beyond that there are some exciting additions to the Blackmagic Design DeckLink plugin! Framework * Added mlt_profile_list(). Modules * Added decklink producer (i.e. capture, live encoding). * Added keyer output for decklink consumer. * Added AVOptions to the avformat service metadata. * Added support for new major API versions (53) of FFmpeg. Melt * Added '-query profile' option. * Added '-query formats', '-query audio_codecs' and '-query video_codecs'. The recommended version of FFmpeg for use with this release is 0.6.1. Version 0.7.0 - March 27, 2011 This is a major new release due to signficant additions to API, framework, and build. Build * Added support for Windows via MinGW. * Enabled linsys module by default. * Disabled VDPAU by default and added --avformat-vdpau to enable it. * Added support for swfdec 0.7. Framework: * Added parallelism to mlt_consumer when 'real_time' > 1 or < -1. * Added mlt_deque_insert() and mlt_deque_peek(). * Added mlt_profile parameter to mlt_producer_new(). * Let transitions with no out point run forever. * Added mlt_frame_unique_properties(). * Added mlt_frame_set_image() and mlt_frame_set_alpha(). * Added mlt_image_format_size() and mlt_audio_format_size(). * Added mlt_filter_get_length() and mlt_transition_get_length(). * Added mlt_filter_get_progress(), mlt_transition_get_progress(), and mlt_transition_get_progress_delta(). * Added mlt_filter_get_position() and mlt_transition_get_position(). * Added mlt_properties_lock() and mlt_properties_unlock(). Modules * Added rotoscoping filter. * Improve libavdevice support (V4L2, ALSA, libdc1394). * Added support for new FFmpeg metadata API. * Various fixes, refactoring, and improvements. The recommended version of FFmpeg for use with this release is 0.6.1. Version 0.6.2 - January 23, 2011 This is just a minor release to address a few things prior to introducing major changes from other branches. * Added force_aspect_ratio property to pixbuf and qimage producers. * Added opacity handling in geometry property of the affine filter and transition. * Added use_normalised property to affine filter. * Added always_active property to affine transition. * Fix building on NetBSD. The recommended version of FFmpeg for use with this release is 0.6.1. Version 0.6.0 - January 1, 2011 The recommended version of FFmpeg for use with this release is 0.6.1. There were quite a few enhancements and changes including a minor interface change. Therefore, this release gets a jump in the versioning. Framework * mlt_profile - Added (Y'CbCr) colorspace attribute. - Added mlt_profile_clone(). * Added mlt_consumer_position() and Mlt::Consumer::position(). * Added Mlt::Properties::wait_for(string). * Added a version API: mlt_version_get_int() and others. * Added Mlt::Producer::pause(). * Added mlt_frame_write_ppm() for debugging. Melt * Added automatic detection of profile from first input when profile not specified. * Now exits with error result when consumer fails fatally. Modules * Added swfdec producer for Flash files including variables support. (Does not support audio.) * Added consumer for Blackmagic Design DeckLink SDI and Intensity HDMI. * Added Y'CbCr colorspace conversion and option to use full luma range. * Added (de)serialization of profile to XML. * Added support for #frame# variable to the data_show filter. * Added support for frei0r string parameters. * Make FFmpeg formats and codecs available as properties (not just stderr). * Try to load .xml file as MLT XML. * Added a consumer-sdl-paused event to sdl_preview. * Added a consumer-fatal-error event to avformat. * Change composite transition to default to progressive rendering; field- based rendering available only explicitly. Version 0.5.10 - September 13, 2010 This is a quick followup to the 0.5.8 release to address an issue I want to address immediately. I noticed an extra unconditional colorspace conversion to and from RGB was added for all YCbCr (YUV) video sources. In addition, I have enabled the avcolor_space filter on OS X since it works now. Version 0.5.8 - September 12, 2010 The recommended version of FFmpeg for use with this release is 0.6. This is a maintenance release to address some bugs that appeared thus far in the 0.5.x series. Beyond that is a few enhancements: * Added EXIF-based auto-rotation of images to pixbuf and qimage producers. * Improved quality of libswscale-based image conversion and scaling. * Added channelswap and panner audio filters; panner also does balance. * Improve audio waveform and add audiowave video filter. * Enhanced luma filter to work with animated filters such as affine. * Automatically crop 8 bottom lines of 1088 source in a 16:9 project (common in Canon EOS digital cameras). * Added support for inline images in kdenlivetitler. Version 0.5.6 - June 20, 2010 The recommended version of FFmpeg for use with this release is 0.6. This is a maintenance release to address some bugs that appeared this far in the 0.5.x series. Beyond that it a few enhancements: * Added interpolation to the affine transition and filter. * Added multi-track audio encoding to avformat consumer. * Added interlaced field rendering to kdenlivetitle producer. Version 0.5.4 - April 19, 2010 The recommended version of FFmpeg for use with this release is SVN r21322. This is another maintenance release to address some bugs that appeared this far in the 0.5.x series. Beyond that it adds two things that only very specific users will see: * Added C# (ECMA CLR) binding (not enabled by default). * Linsys SDI consumer now configures itself from MLT profile. Version 0.5.2 - March 10, 2010 The recommended version of FFmpeg for use with this release is SVN r21322. This is a minor maintenance release, but it is interesting because it now enables usage of libswscale as the default choice for image scaling, image format conversion, and color space conversion. That gives better quality and performance. In addition, there are some improvements in the sdl_preview consumer to make it suitable for use in OpenShot 1.1. Other things: * Fixed mlt++/MltFilteredProducer * Fixed playing to the end in Kdenlive (mantis bug 1207) * Fixed crash load uncompressed video * Fixed compiling yadif for non-sse2 builds Version 0.5.0 - February 15, 2010 The recommended version of FFmpeg for use with this release is SVN r21322.

In particular, this adds support for VDPAU, YADIF, and HD-SDI technologies! configure: added --disable-sse2 framework: * mlt_cache: added mlt_cache_set_size() * mlt_filter: added data property "service" - set when attached * mlt_frame: - added Doxygen docs - added "previous frame" and "next frame" data properties - available when its producer has _need_previous_next=1 * mlt_playlist: added support for negative out point same as length-1 * mlt_service: - added mlt_service_cache_purge() - added "_need_previous_next" handling in mlt_service_get_frame() - added firing event "service-changed" in mlt_service_attach() modules: * avformat producer: - added decoding H.264 with NVIDIA VDPAU Requires FFmpeg built with vdpau. This is automatically detected and enabled. You can disable this by setting environment variable MLT_NO_VDPAU=1 or property novdpau=1. - added caching of FFmpeg contexts and decoded images This allows large numbers of clips in a project avoiding limitations with number of threads and file descriptors permitted per process. You can disable image caching with property noimagecache=1. - added variant of producer named avformat-novalidate - restored support for video4linux(2) * avformat consumer: added apre, fpre, and vpre preset properties * crop filter: added center_bias integer property * deinterlace filter: added the excellent YADIF as a method * kdenlivetitle producer: added text outlining * linsys/sdi consumer: - added support for HD-SDI - changed name from "linsys_sdi" to just "sdi" * oldfilm filter: added "uneven development" effect * xml producer: add support for unspecified out points profiles: * added several missing ATSC (HD) profiles * change descriptions from using Hz to fps Version 0.4.10 - December 8, 2009 The recommended version of FFmpeg for use with this release is SVN r19873.

Also, please create clips clip1.dv, clip2.dv, clip3.dv, clip1.mpeg, clip2.mpeg, clip3.mpeg, and music1.ogg. Please make sure clips are at least 500 frames duration. These notes explain the the concepts presented in each demonstration and what details to look for. First, a note on consumers. When you start the script, the main menu asks you to choose a consumer. A consumer is like a viewer, but it could also write to a stream/file. The "SDL" consumer is the popular Simple DirectMedia Layer audio and video output. The "xml" consumer generates an XML representation of the service network. That can be played directly due to the XML producer plugin. See docs/mlt-xml.txt for more information. "/dev/dv1394/0" refers to a device file for transmitting DV over FireWire using the Linux dv1394 kernel module. These examples assume the numeric locale LC_NUMERIC decimal separator is a period. Therefore, the demo script sets LC_NUMERIC=C for you, but if you are running these manually or learning from them, remember to use the appropriate separator for your locale. And now the demos... All clips Simply builds a playlist containing each video clip, and you can transport between them using j and k keys. Filter in/out A video filter can be applied to a portion of a producer (clip, playlist, or multitrack). This examples shows the greyscale filter. Watermark A graphic can overlay video in realtime with support for alpha channel. This example uses a PNG file with an alpha channel. Distortion is explicitly enabled here so the otherwise circular graphic is scaled to fill the compositing region. By default, compositing honours the aspect ratio of the overlay. My name is... Titles are very easy to composite in realtime. The titler uses Pango with the FreeType2 rendering backend. This means it supports high quality scalable font rendering with anti-aliasing, unicode (UTF-8), and Pango markup capabilities. The compsiting here respects the aspect ratio of the rendered title in the first two title pieces but distorts the final one. This demo also shows the motion and scaling capabilities of the compositor in conjunction with honouring aspect. The compositor is doing field-based rendering. So, when displayed non-progressively with SDL, you can see motion artifacts during animation. A composite transition The compositor also handles video over video as demonstrated in this usage of the compositor to create a special transition. This demonstration also crossfades the audio during the transition! Progressive rendering is explicitly enabled on the compositor due to the poor results that would otherwise occur due to scaling an interleaved video frame and moving the video in a reverse direction horizontally. Fade in and out A simple series of transitions betwen 3 clips using dissolves and audio crossfades. This is easy :-). Clock in and out Wipe transitions are very easy and highly extensible as they are generated using a very convenient lookup table based upon the luma of an image. This image can be a 16 bit PGM (grayscale bitmap) or the luma channel of any video producer. A number of high quality wipes can be downloaded from http://mlt.sf.net/. It also performs field rendering. The second wipe demonstrates the ability to control the direction of the wipe as well. Obscure A popular requirement in news production is to obscure a face, obscenity, or trademarked logo. This demonstrates using a simple rectangular obscure filter applied to a region of the image. The second example is more advanced and shows using the "region" filter to select the image area and a property of the region filter to "shape" the region using the alpha channel of another image (circle.png) and another property to "filter" the region using the obscure filter. Audio Stuff A music bed sound track can be mixed with a video. The sound track of the video clip has a "floating" amplitude normalisation filter applied. Typically, audio normalisation applies a constant gain factor across the entire duration of an audio segment from a single source where the gain factor is automatically determined by anaylsing the maximum "power" or peak levels. However, in news production, a popular requirement is to to dynamically boost the amplitude in soft areas and reduce the amplitude in louder areas. Thus, the gain analysis is performed using a "sliding window" approach. This example also applies a constant gain factor of 0.5 (50%) to the normalised audio of the video clip (to get a nicer mix level). Audio and Video Levels Audio can be normalised by setting a target amplitude level in decibels. A gamma curve can be applied to the luma channel of video. Shadowed Title and Watermark Two instances of the titler are used to create a shadow effect. The aspect ratio of the watermark in this example is not distorted. Since the original image is a circle with square pixels--a computer-generated image--and ITU BT.601 video is not composed of square samples. Therefore, the compositor normalises the pixel aspect ratio of the overlay to the destination image, and the circular image remains circular on the analog video output. Finally, a greyscale filter is applied to the watermark while its opacity is set at 30%. Station Promo into Story? Here is fun demo that might show using a still graphic with some music to introduce a show. A luma wipe with an audio crossfade transitions from the show title or station promotional material. Voiceover 2 clips with title A common news production requirement to have a "voiceover" audio track to a clip or even multiple clips as demonstrated here. Likewise, it is common to place a title caption on the video at the same time! This demo has a little fun with the titler at the sake of practicality :-) The foreground of the title is transparent while the opacity of the background is reduced to blend with the video. Meanwhile, the compositor stretches the image to fill the bottom slice of the video--not suitable for overscan displays ;-) Also, pay close attention to the mixing levels of the audio tracks. The audio of the video fades out as the voiceover track (just music in this demo) fades in. Then, the voiceover remains mixed with the ambient audio at a 60% level. Finally, the voiceover fades out smoothly from the 60% level to nothing. GJ-TTAvantika title This demo requires a special TrueType font called Avantika. If you have the font, register it with fontconfig using the fc-cache utility. This demonstrates i18n capabilities of the titler and the alignment capabilities of both the titler and the compositor. The titler centre aligns the two lines of text, and the compositor centre aligns the title horizontally on the frame. Title over graphic You can superimpose a title over a graphic over video! Also, you can apply a luma wipe to the compositor! Slideshow This demo requires any number of JPEG images with the extension ".jpg" in a subdirectory named "photos." Bouncy, Bouncy The "watermark" filter encapsulates the compositor, and you have full control over the compositor properties. Who says a watermark can not also be a video?! Bouncy, Bouncy Ball A variation on the above Bouncy, Bouncy demo that applies a shape, or alpha producer, to the the compositing region. Breaking News This demonstrates layout capabilities of the compositor. Squeeze Transitions This demonstrates a distorting barndoor-like wipe. J Cut A J cut is an edit where the audio cuts before the video. It gets its name from the way it looks on a NLE timeline user interface. When the audio cuts over, it does an audio crossfade over the duration of one frame. This makes the audio cut slightly less abrupt and avoids any "click" due to mismatched sample levels at the edit point. The video edit is a hard cut. L Cut An L cut is an edit where the video cuts before the audio. It gets its name from the way it looks on a NLE timeline user interface. This demo shows a very quick dissolve over 5 frames for a soft video cut. Like the J Cut demo, an audio crossfade for the duration of one frame makes an audio edit nearly instantaneous while being slightly softened and avoiding aberrations. Fade from/to black/silence Of course, it is possible using MLT to fade from black on video and silence on audio as well fade to black and silence. Push wipe A push wipe is a somewhat fancier transition than most standard wipes because it involves motion. The new video clip "pushes" the old video clip off one edge. If you can preview on an analog monitor you will notice how smooth the motion is due to field-based rendering. Ticker tape A very minimal reverse crawling title neard the bottom of the screen. The goal of the demo is show fluid motion of the field-based rendering of the compositor when viewed on an analog monitor using a DV or BlueFish444 consumer. The demo also shows the potientional for using and extending the existing set of services for a full blown news ticker implementation. Pango Keyframed Markup You can create timed text and subtitles using a .mpl file, which is a properties format file. A properties file contains key=value pairs on separate lines. For .mpl the key is a frame number and the value is Pango Markup Language. A tilde is interpreted as a new line. This example also demonstrates using the watermark and the alignment properties of its encapsulated composite transition where halign is the horizontal, valign is the vertical, c is for center, and m is for middle. mlt-0.9.0/demo/circle.png000066400000000000000000000121671215300731300152110ustar00rootroot00000000000000‰PNG  IHDR,,y}ŽusBIT|dˆ.IDATxœíÝa°\eyÀñÿ½×$0BbÃ$”(HDef ¥¥kÇi;¥N?8µ¢V«vô›ŽÎtª3N¿´ú¡VeTÀ©Ž #&à@'VˆB 4$&!q’÷Þ~xö&››Ý½gwÏ9ï9gÿ¿™göÆ{÷œGö=ϼï»ïyÏÒéÎÖ‹%­/™õó"à `0¿ Ú^Ç£ÀËÀñÖëÌÏÇ€CÀ~àÅÖkûÏ€­K'Œ¥N@IŒ—«Z¯«3S%6ËQàIài`wëuð8ð0*1¥aÁj¾¥ÀeÀ[Ú^×R¢4¨£ÀvàQà‘¶×R&¥bY°šgð.`#p-p~ÒlÊ÷ p/° ø ð\Òl”+ Vý-6´b#1÷¤“vÅks+ö¥MGð`ÕÏbàN¨µø9f5M #g Ø}Ä¿j†^}cÀ DqÚ¬#¾Ó𦀭DñÚÜùÒ@Ö_ö‘Q|ìmý7_—áó‘FÞJàSÀc¤¿xG=k}+{~bÒˆ9 ¸ø10Iú Õ85&[ŸÍ-­ÏJ9ÀõÀ׀ä¿(lq¸õ™]ßú ¥F»øÎK5!ö¶>Ë‹‘fp;ùš“­ÏÖ‰zÕÞzà‡Ä×ç©/,£Ø˜j}Öë‘jæ:bmOê‹ÈH›‰6 UÖp°…ôŒQØB´ h«2&€ÛHÕŒmDñ›E%3ø °ƒô„QØA´™yH%ÚHl$—ú0껈6$ê<àÒ7x£qѦ¤\Í#î+;BúFn4+ŽmËa¢rq-±‡Rê†m4;¶mMÈràë¸èÓ(/¦ˆ6·)£ à£ÀAÒ7`c4ã Ñ]¡ž®"v LÝ` cšh‹W!Í2ø,ÿŒêÅÑ6”Wpò¡œ†QÕx‚h«a&È™º1F–8J´Y˜…À·Hß cøцGÎ(ÞE¾ŽøÀW§NDÂ“Ä Õ[S'R¦QûÚôV¢X-Kˆ4¤ß!n¤>üOÚT”·EÀwHß•7Œ"â;Do¼Q^Iôª.LˆT §ˆ!⃩)R“‡„cÀÇ€Û€¥‰s‘Š¶ø à% |²äsJ*ÆZ`%.u(sHx1oåÞVRs#æ³.ãde¬…Dö¦f©yv À ŸÏ*kHøeàú’Î%©\Kˆ§ï|¿è•ÑúŠØŒ/õ"UIÅ™"6ýÛRäIŠ.XÀωù+IÍö0ðv`²¨=$¼øË‚Ï!©Î^¤ÀUðEö°– ò!Òè8¼x¾ˆƒ9¯ôÏX¬¤Q³ˆ¸ö QTëZ`SÇ—T]ÓÀFàÞ¼\DA™ü‚¸«[Òhú%ðVà•<ZĤûßRÀq%ÕÇRà·Ä’¦ÜäÝÃ:¨¬¯Íù¸’êç·ÄHëÙ¼˜÷¤û±XI ¯%jBnòìa½‡xð¢$µ»øQÊ«`7@º?»¤Ùž"6>˜ö@y oÁb%©³ ‰1´ÃCtÁ$© ž%özN-XK™µæA’*`qoó)CÂËÒä"I=¨Míë- ‘¤¹œ¨Mö°$U=,Iµq¢6ÍLºO‡3“¤#IÝÎ&gzX«±XIª¦3‰ubHø¦t¹HÒœÞ' Öª„‰HÒ\VÁÉ‚uAº<$iN€=,Iõ`KRm\'—5¼D|m(IUtX8œCëÆBIª°¥ã´mÝ Ivþ8ðúÔYHR¯–¤ÎB’2X2NÌaIRÕcKR],±`Iª ‡„’jÃ!¡¤ÚX2¼.u’”ÁëÆ©³¤ X°$ÕÅ‚q`~ê,$)ƒù,Iu1ß!¡¤ºpH(©6æ¯Ï%”¤*›Ÿûo$©Æã©“¤ Ž/§ÎB’2xÙ–¤º°‡%©6^¶`Iª ‡„’jã¸KR]¦ÎB’288ìO…$e°x1u’”Á‹ö°$ÕÅ~ –¤ºpH(©6JªýãÀÞÔYHR{Lj'?¿:IšÃÒ±Ö/g§ÌD’z8 ,œÙqô鄉HÒ\ž†ØqôÄ?$©¢ž†“kwº<$iN»Á–¤zxìaIª‡SzX¿J˜ˆ$ÍåW3Ë&ˆ¯ ÏL–Ž$uv”XvuâAª“ÀötùHRWÛ‰Eû“ŸM“‹$õt¢6µ¬G$"Is9Q›ìaIªºµi¬í\ ì+?Iêi­ Ú{X/Ï&IG’:{–¶ÝdÆgýrs¹¹HRO§Ô¤ÙkS‰‰HÒ\N©Ic³~ùJªŽó€_Ïücvë×ÀÎRÓ‘¤ÎvÒV¬àô‚ %UÃiµ¨SÁrâ]RœV‹fÏaA¬yx¾Ëï$© ÓÀrf­ íÔÃÚ‡7BKJk;²w*Xà<–¤´:Ö nËy,I)u¬AÝæ©Ëá' KG’:›$îm>0ûÝzX€‡‹ÌH’ºx˜Å º,pX()®µ§WÁº§€D$i.]kO¯µV¯ž#ÖeIRö+€W;ý²WëUà¶"2’¤.n£K±‚Þ àkùæ"I=õ¬9Yn¿y X›O.’ÔÕvàͽþ`®Àæ“‹$õ4g­ÉÒÃZ ÇÅ òYü9AlIÇ’ÔL³É|ß`'yìÓ> |>‡ãHj®Ï3d±‚ün¯'nŠ¾0§ãIjŽ§ˆ›œ§†=P^O™nÍéX’šåVr(V~„;9H:ÕDmÈEÞ;.œüxmÎÇ•T?¿.žÍë€y¨å1±v]ÎÇ•T?Ÿ~˜ç‹ØÓj±˜ôÒŽ-©~I,}%σñøùW€0ä1Iµ5MÔ€\‹S° ¶øfAÇ–Tmߤ í§ŠÜæx9°XTà9$UË!àÀóE<ïI÷vGˆo ÞSà9$UË'ME¼èIL?®(ø<’Ò{x;9Ü‚ÓMQsX3&¿&§U®’*kŠ¸Ö +VP|Á‚Ø•ô«%œGR:_%®õB•õlÁ…ij ×”t>IåÙI¼Bªƒ§€uÄ ÎI¤˜Ãjw糤:˜™·JV¬ ÝV»ÿ%&ïÜÕAª®ßMDê!a»;€÷¥NBÒiîþ(uP­‚5ø>ÀBª’{ˆ»S^NT«`œ l&¤IJë!`p8u"3ªV°–÷ãÎRJ;«}©iWÅ‚° x87u"ÒÚ¬v§Nd¶Ô˺ÙM|k˜ô+Ti"®½Ê+¨nÁØü!î¡%•åqÍmKH7U.X÷JÁûDKb’¸ÖîKH/UX8:—Äæ7¥NDj°ßHÄ\êP° ¾^"¾b•”¯Ï_LDu)X?–ïHˆÔ ÿ üCê$²ªSÁ¸ XAÜ1.i8_>L§N$«º¬ibÃ{‡‡Òp>|‚+¨_ÁšñSbqÛTÿ›N©J&‰ öZÌYÍVÕ•îYÝ |8#u"R #–.$ß&fPu/X×ûK/JˆTa‡ˆE¡•^g5—&,€Ë὇R'{ˆÛm*»‚=«¦,ˆ¦ïÆ]¤v;¨è½ýjÒ„õnb;Œ‡R'"UÄCÄ5шbÍ*X{÷l vI”FÙ=ĵP©ý¬†Õ´‚±;âÀ÷R'"%ò=â¨ÌN¡yibÁxx/ð7ø1ŽãD›/q 4N“&Ý»¹ø>¬UÍöñÜÀS'R¤¦ö°Ú=HÜ{x{êD¤‚ÜN´ñF«Qt+±ÚwÚ0Lj6=2FaH8Û:bˆ¸:u"Òž$†€[S'R¦Qζ•xîá·S'" èÛD©b¥¸ký(é»ö†‘%ŽmV#ì à Ò7FÃèOmUbðYbcÀÔ Ó0ÚcŠh›óf¹Š˜HÝH cšh‹W!õ0|8HúkŒf$Ú`]wV˯ã0Ñ(/¦ˆ6·i@×ÛIߘfÇv¢­IC›| 8Bú†m4+ŽmËIuåî<àÒ7r£qѦ¤Bmv‘¾ÁõŒ]D’J3ø °ƒô€QØA´‡Jf‚¸ ué/£š±h#.SPeŒ7[HÕˆ-D›Å]QT#×›IÁib3ѤZYüŸŽBLµ>ëõH57³Eó$é/,#ߘääÅR£\ |ØKú Í.ö¶>Ë‹‘n¸øñì¸ÔŸ‘-·>³ëñ?¨³€[€㱊1Ùúlni}V’ZV÷•=Fú uÔã±Ög±²ç'& ˆIÜ/á|W™±·õßÜ ôŠrA[õ7÷žm .¦Q|ÚQ¦ˆ]=7›€»‰Â¥Š²`ÕÏbà¢xmÖâç˜Õ4±ïÔ&¢HÝHš‘úbC¯¿eDñš)`kÒ¦S9;9Y 6ûÒ¦£aX°šgð.¢x] œŸ4›ò=ÜK©ŸÏ%ÍF¹²`5ßRà2à-m¯k3S&•ƒ£ÄðîQà‘¶×R&¥bY°FÓ±Bûà"à`Uëu5Õ)fG'§Ý­×]Àãœ|ø­FˆKœCÌ…-–´þ½dÖÏ‹€3€ÀüV,h{' ÎËÀñÖëÌÏÇ€CÀ~àÅÖkûψ¹§‹þ?ªzùK¸„¡8eÇIEND®B`‚mlt-0.9.0/demo/circle.svg000066400000000000000000000001251215300731300152130ustar00rootroot00000000000000 mlt-0.9.0/demo/consumers.ini000066400000000000000000000004741215300731300157570ustar00rootroot00000000000000SDL Default sdl SDL Half D1 sdl:360x288 rescale=nearest resize=1 SDL High Latency sdl buffer=12 rescale=none SDL Progressive sdl progressive=1 XML to Terminal xml XML to File xml: libdv to /dev/dv1394/0 libdv:/dev/dv1394/0 rescale=nearest buffer=25 DeckLink decklink DeckLink Prog LL decklink progressive=1 buffer=1 mlt-0.9.0/demo/demo000077500000000000000000000040171215300731300141070ustar00rootroot00000000000000#!/bin/bash export MLT_PROFILE=dv_pal export LC_NUMERIC=C function show_consumers( ) { awk -F '\t' '{ printf( "%d. %s\n", ++ i, $1 ); }' < consumers.ini } function get_consumer( ) { option=$1 [ "$option" != "" ] && [ $option -gt 0 ] && sed 's/\t\+/\t/g' < consumers.ini | cut -f 2 | head -n $option | tail -n -1 } function show_menu( ) { sed 's/\t\+/\t/g' < demo.ini | awk -F '\t' '{ printf( "%2d. %-30.30s", ++ i, $2 ); if ( i % 2 == 0 ) printf( "\n" ); } END { if ( i % 2 == 1 ) printf( "\n" ); }' } function check_dependencies( ) { option=$1 if [ $option -gt 0 ] then deps=`sed 's/\t\+/\t/g' < demo.ini | cut -f 3 | head -n $option | tail -n -1` if [ "$deps" != "" ] then echo "$deps" | tr ',' '\n' | while read dep do ls $dep > /dev/null 2>&1 val=$?

As such, it provides a pluggable architecture for the inclusion of new audio/video sources, filters, transitions and playback devices. The framework provides the structure and utility functionality on which all of the MLT applications and services are defined. On its own, the framework provides little more than 'abstract classes' and utilities for managing resources, such as memory, properties, dynamic object loading and service instantiation. This document is split roughly into 3 sections. The first section provides a basic overview of MLT, the second section shows how it's used and the final section shows structure and design, with an emphasis on how the system is extended. Target Audience: This document is provided as a 'road map' for the framework and should be considered mandatory reading for anyone wishing to develop code at the MLT level. This includes: 1. framework maintainers; 2. module developers; 3. application developers; 4. anyone interested in MLT. The emphasis of the document is in explaining the public interfaces, as opposed to the implementation details. It is not required reading for the MLT client/server integration - please refer to libmvsp.txt and mvsp.txt for more details on this area. SECTION 1 - BASIC OVERVIEW -------------------------- Basic Design Information: MLT is written in C. The framework has no dependencies other than the standard C99 and POSIX libraries. It follows a basic Object Oriented design paradigm, and as such, much of the design is loosely based on the Producer/Consumer design pattern. It employs Reverse Polish Notation for the application of audio and video FX. The framework is designed to be colour space neutral - the currently implemented modules, however, are very much 8bit YUV422 oriented. In theory, the modules could be entirely replaced. A vague understanding of these terms is assumed throughout the remainder of this document. Structure and Flow: The general structure of an MLT 'network' is simply the connection of a 'producer' to a 'consumer': +--------+ +--------+ |Producer|-->|Consumer| +--------+ +--------+ A typical consumer requests MLT Frame objects from the producer, does something with them and when finished with a frame, closes it. /\ A common confusion with the producer/consumer terminology used here is /!!\ that a consumer may 'produce' something. For example, the libdv consumer \!!/ produces DV and the libdv producer seems to consume DV. However, the \/ naming conventions refer only to producers and consumers of MLT Frames. To put it another way - a producer produces MLT Frame objects and a consumer consumes MLT Frame objects. An MLT Frame essentially provides an uncompressed image and its associated audio samples. Filters may also be placed between the producer and the consumer: +--------+ +------+ +--------+ |Producer|-->|Filter|-->|Consumer| +--------+ +------+ +--------+ A service is the collective name for producers, filters, transitions and consumers. The communications between a connected consumer and producer or service are carried out in 3 phases: * get the frame * get the image * get the audio MLT employs 'lazy evaluation' - the image and audio need not be extracted from the source until the get image and audio methods are invoked. In essence, the consumer pulls from what it's connected to - this means that threading is typically in the domain of the consumer implementation and some basic functionality is provided on the consumer class to ensure realtime throughput. SECTION 2 - USAGE ----------------- Hello World: Before we go in to the specifics of the framework architecture, a working example of usage is provided. The following simply provides a media player: #include #include #include int main( int argc, char *argv[] ) { // Initialise the factory if ( mlt_factory_init( NULL ) == 0 ) { // Create the default consumer mlt_consumer hello = mlt_factory_consumer( NULL, NULL ); // Create via the default producer mlt_producer world = mlt_factory_producer( NULL, argv[ 1 ] ); // Connect the producer to the consumer mlt_consumer_connect( hello, mlt_producer_service( world ) ); // Start the consumer mlt_consumer_start( hello ); // Wait for the consumer to terminate while( !mlt_consumer_is_stopped( hello ) ) sleep( 1 ); // Close the consumer mlt_consumer_close( hello ); // Close the producer mlt_producer_close( world ); // Close the factory mlt_factory_close( ); } else { // Report an error during initialisation fprintf( stderr, "Unable to locate factory modules\n" ); } // End of program return 0; } This is a simple example - it doesn't provide any seeking capabilities or runtime configuration options. The first step of any MLT application is the factory initialisation - this ensures that the environment is configured and MLT can function. The factory is covered in more detail below. All services are instantiated via the factories, as shown by the mlt_factory_consumer and mlt_factory_producer calls above. There are similar factories for filters and transitions. There are details on all the standard services in services.txt. The defaults requested here are a special case - the NULL usage requests that we use the default producers and consumers. The default producer is "loader". This producer matches file names to locate a service to use and attaches 'normalising filters' (such as scalers, deinterlacers, resamplers and field normalisers) to the loaded content - these filters ensure that the consumer gets what it asks for. The default consumer is "sdl". The combination of loader and sdl will provide a media player. In this example, we connect the producer and then start the consumer. We then wait until the consumer is stopped (in this case, by the action of the user closing the SDL window) and finally close the consumer, producer and factory before exiting the application. Note that the consumer is threaded - waiting for an event of some sort is always required after starting and before stopping or closing the consumer. Also note, you can override the defaults as follows: $ MLT_CONSUMER=xml ./hello file.avi This will create a XML document on stdout. $ MLT_CONSUMER=xml MLT_PRODUCER=avformat ./hello file.avi This will play the video using the avformat producer directly, thus it will bypass the normalising functions. $ MLT_CONSUMER=libdv ./hello file.avi > /dev/dv1394 This might, if you're lucky, do on the fly, realtime conversions of file.avi to DV and broadcast it to your DV device. Factories: As shown in the 'Hello World' example, factories create service objects. The framework itself provides no services - they are provided in the form of a plugin structure. A plugin is organised in the form of a 'module' and a module can provide many services of different types. Once the factory is initialised, all the configured services are available for use. The complete set of methods associated to the factory are as follows: int mlt_factory_init( char *prefix ); const char *mlt_factory_prefix( ); char *mlt_environment( char *name ); mlt_producer mlt_factory_producer( char *name, void *input ); mlt_filter mlt_factory_filter( char *name, void *input ); mlt_transition mlt_factory_transition( char *name, void *input ); mlt_consumer mlt_factory_consumer( char *name, void *input ); void mlt_factory_close( ); The mlt_factory_prefix returns the path to the location of the installed modules directory. This can be specified in the mlt_factory_init call itself, or it can be specified via the MLT_REPOSITORY environment variable, or in the absence of either of those, it will default to the install prefix/shared/mlt/modules. The mlt_environment provides read only access to a collection of name=value pairs as shown in the following table: +------------------+------------------------------------+------------------+ |Name |Description |Values | +------------------+------------------------------------+------------------+ |MLT_NORMALISATION |The normalisation of the system |PAL or NTSC | +------------------+------------------------------------+------------------+ |MLT_PRODUCER |The default producer |"loader" or other | +------------------+------------------------------------+------------------+ |MLT_CONSUMER |The default consumer |"sdl" or other | +------------------+------------------------------------+------------------+ |MLT_TEST_CARD |The default test card producer |any producer | +------------------+------------------------------------+------------------+ These values are initialised from the environment variables of the same name. As shown above, a producer can be created using the 'default normalising' producer, and they can also be requested by name. Filters and transitions are always requested by name - there is no concept of a 'default' for these. Service Properties: As shown in the services.txt document, all services have their own set of properties than can be manipulated to affect their behaviour. In order to set properties on a service, we need to retrieve the properties object associated to it. For producers, this is done by invoking: mlt_properties properties = mlt_producer_properties( producer ); All services have a similar method associated to them. Once retrieved, setting and getting properties can be done directly on this object, for example: mlt_properties_set( properties, "name", "value" ); A more complete description of the properties object is found below. Playlists: So far, we've shown a simple producer/consumer configuration - the next phase is to organise producers in playlists. Let's assume that we're adapting the Hello World example, and wish to queue a number of files for playout, ie: hello *.avi Instead of invoking mlt_factory_producer directly, we'll create a new function called create_playlist. This function is responsible for creating the playlist, creating each producer and appending to the playlist. mlt_producer create_playlist( int argc, char **argv ) { // We're creating a playlist here mlt_playlist playlist = mlt_playlist_init( ); // We need the playlist properties to ensure clean up mlt_properties properties = mlt_playlist_properties( playlist ); // Loop through each of the arguments int i = 0; for ( i = 1; i < argc; i ++ ) { // Create the producer mlt_producer producer = mlt_factory_producer( NULL, argv[ i ] ); // Add it to the playlist mlt_playlist_append( playlist, producer ); // Close the producer (see below) mlt_producer_close( producer ); } // Return the playlist as a producer return mlt_playlist_producer( playlist ); } Notice that we close the producer after the append. Actually, what we're doing is closing our reference to it - the playlist creates its own reference to the producer on append and insert, and it will close its reference when the playlist is destroyed[*]. Note also that if you append multiple instances of the same producer, it will create multiple references to it. Now all we need do is to replace these lines in the main function: // Create a normalised producer mlt_producer world = mlt_factory_producer( NULL, argv[ 1 ] ); with: // Create a playlist mlt_producer world = create_playlist( argc, argv ); and we have a means to play multiple clips. [*] This reference functionality was introduced in mlt 0.1.2 - it is 100% compatable with the early mechanism of registering the reference and destructor with the properties of the playlist object. Filters: Inserting filters between the producer and consumer is just a case of instantiating the filters, connecting the first to the producer, the next to the previous filter and the last filter to the consumer. For example: // Create a producer from something mlt_producer producer = mlt_factory_producer( ... ); // Create a consumer from something mlt_consumer consumer = mlt_factory_consumer( ... ); // Create a greyscale filter mlt_filter filter = mlt_factory_filter( "greyscale", NULL ); // Connect the filter to the producer mlt_filter_connect( filter, mlt_producer_service( producer ), 0 ); // Connect the consumer to filter mlt_consumer_connect( consumer, mlt_filter_service( filter ) ); As with producers and consumers, filters can be manipulated via their properties object - the mlt_filter_properties method can be invoked and properties can be set as needed. The additional argument in the filter connection is an important one as it dictates the 'track' on which the filter operates. For basic producers and playlists, there's only one track (0), and as you will see in the next section, even multiple tracks have a single track output. Attached Filters: All services can have attached filters. Consider the following example: // Create a producer mlt_producer producer = mlt_factory_producer( NULL, clip ); // Get the service object of the producer mlt_producer service = mlt_producer_service( producer ); // Create a filter mlt_filter filter = mlt_factory_filter( "greyscale" ); // Create a playlist mlt_playlist playlist = mlt_playlist_init( ); // Attach the filter to the producer mlt_service_attach( producer, filter ); // Construct a playlist with various cuts from the producer mlt_playlist_append_io( producer, 0, 99 ); mlt_playlist_append_io( producer, 450, 499 ); mlt_playlist_append_io( producer, 200, 399 ); // We can close the producer and filter now mlt_producer_close( producer ); mlt_filter_close( filter ); When this is played out, the greyscale filter will be executed for each frame in the playlist which comes from that producer. Further, each cut can have their own filters attached which are executed after the producer's filters. As an example: // Create a new filter filter = mlt_factory_filter( "invert", NULL ); // Get the second 'clip' in the playlist producer = mlt_playlist_get_clip( 1 ); // Get the service object of the clip service = mlt_producer_service( producer ); // Attach the filter mlt_service_attach( producer, filter ); // Close the filter mlt_filter_close( filter ); Even the playlist itself can have an attached filter: // Create a new filter filter = mlt_factory_filter( "watermark", "+Hello.txt" ); // Get the service object of the playlist service = mlt_playlist_service( playlist ); // Attach the filter mlt_service_attach( service, filter ); // Close the filter mlt_filter_close( filter ); And, of course, the playlist, being a producer, can be cut up and placed on another playlist, and filters can be attached to those cuts or on the new playlist itself and so on ad nauseum. The main advantage of attached filters is that they remain attached and don't suffer from the maintenance problems associated with items being inserted and displacing calculated in/out points - this being a major issue if you exclusively use the connect or insert detached filters in a multitrack field (described below). Introducing the Mix: The mix is the simplest way to introduce transitions between adjacent clips on a playlist. Consider the following playlist: +-+----------------------+----------------------------+-+ |X|A |B |X| +-+----------------------+----------------------------+-+ Let's assume that the 'X' is a 'black clip' of 50 frames long. When you play this out, you'll get a 50 frames of black, abrupt cut into A, followed by an abrupt cut into B, and finally into black again. The intention is to convert this playlist into something like: +-+---------------------+-+------------------------+-+ |X|A |A|B |B| |A| |B| |X| +-+---------------------+-+------------------------+-+ Where the clips which refer to 2 clips represent a transition. Notice that the representation of the second playlist is shorter than the first - this is to be expected - a single transition of 50 frames between two clips will reduce the playtime of the result by 50 frames. This is done via the use of the mlt_playlist_mix method. So, assuming you get a playlist as shown in the original diagram, to do the first mix, you could do something like: // Create a transition mlt_transition transition = mlt_factor_transition( "luma", NULL ); // Mix the first and second clips for 50 mlt_playlist_mix( playlist, 0, 50, transition ); // Close the transition mlt_transition_close( transition ); This would give you the first transition, subsequently, you would apply a similar technique to mix clips 1 and 2. Note that this would create a new clip on the playlist, so the next mix would be between 3 and 4. As a general hint, to simplify the requirement to know the next clip index, you might find the following simpler: // Get the number of clips on the playlist int i = mlt_playlist_count( ); // Iterate through them in reverse order while ( i -- ) { // Create a transition mlt_transition transition = mlt_factor_transition( "luma", NULL ); // Mix the first and second clips for 50 mlt_playlist_mix( playlist, i, 50, transition ); // Close the transition mlt_transition_close( transition ); } There are other techniques, like using the mlt_playlist_join between the current clip and the newly created one (you can determine if a new clip was created by comparing the playlist length before and after the mix call). Internally, the mlt_playlist_mix call generates a tractor and multitrack as described below. Like the attached filters, the mix makes life very simple when you're inserting items into the playlist. Also note that it allows a simpler user interface - instead of enforcing the use of a complex multitrack object, you can do many operations on a single track. Thus, additional tracks can be used to introduce audio dubs, mixes or composites which are independently positioned and aren't affected by manipulations on other tracks. But hey, if you want a bombastic, confusing and ultimately frustrating traditional NLE experience, that functionality is provided too ;-). Practicalities and Optimisations: In the previous two sections I've introduced some powerful functionality designed to simplify MLT usage. However, a general issue comes into this - what happens when you introduce a transition between two cuts from the same bit of video footage? Anyone who is familiar with video compression will be aware that seeking isn't always without consequence from a performance point of view. So if you happen to require two frames from the same clip for a transition, the processing is going to be excessive and the result will undoubtedly be very unpleasant, especially if you're rendering in realtime... So how do we get round this? Actually, it's very simple - you invoke mlt_producer_optimise on the top level object after a modification and MLT will determine how to handle it. Internally, it determines the maximum number of overlapping instances throughout the object and creates clones and assigns clone indexes as required. In the mix example above, you can simply call: // Optimise the playlist mlt_producer_optimise( mlt_playlist_producer( playlist ) ); after the mix calls have be done. Note that this is automatically applied to deserialised MLT XML. Multiple Tracks and Transitions: MLT's approach to multiple tracks is governed by two requirements: 1) The need for a consumer and producer to communicate with one another via a single frame; 2) The desire to be able to serialise and manipulate a 'network' (or filter graph if you prefer). We can visualise a multitrack in the way that an NLE presents it: +-----------------+ +-----------------------+ 0: |a1 | |a2 | +---------------+-+--------------------------+-+---------------------+ 1: |b1 | +------------------------------+ The overlapping areas of track 0 and 1 would (presumably) have some kind of transition - without a transition, the frames from b1 and b2 would be shown during the areas of overlap (ie: by default, the higher numbered track takes precedence over the lower numbered track). MLT has a multitrack object, but it is not a producer in the sense that it can be connected directly to a consumer and everything will work correctly. A consumer would treat it precisely as it would a normal producer, and, in the case of the multitrack above, you would never see anything from track 1 other than the transitions between the clips - the gap between a1 and a2 would show test frames. This happens because a consumer pulls one frame from the producer it's connected to while a multitrack will provide one frame per track. Something, somewhere, must ensure that all frames are pulled from the multitrack and elect the correct frame to pass on. Hence, MLT provides a wrapper for the multitrack, which is called a 'tractor', and its the tractors task to ensure that all tracks are pulled evenly, the correct frame is output and that we have 'producer like' behaviour. Thus, a multitrack is conceptually 'pulled' by a tractor as shown here: +----------+ |multitrack| | +------+ | +-------+ | |track0|-|--->|tractor| | +------+ | |\ | | | | \ | | +------+ | | \ | | |track1|-|--->|---o---|---> | +------+ | | / | | | | / | | +------+ | |/ | | |track2|-|--->| | | +------+ | +-------+ +----------+ With a combination of the two, we can now connect multitracks to consumers. The last non-test card will be retrieved and passed on. The tracks can be producers, playlists, or even other tractors. Now we wish to insert filters and transitions between the multitrack and the tractor. We can do this directly by inserting filters directly between the tractor and the multitrack, but this involves a lot of connecting and reconnecting left and right producers and consumers, and it seemed only fair that we should be able to automate that process. So in keeping with our agricultural theme, the concept of the 'field' was born. We 'plant' filters and transitions in the field and the tractor pulls the multitrack (think of a combine harvester :-)) over the field and produces a 'bail' (sorry - kidding - frame :-)). Conceptually, we can see it like this: +----------+ |multitrack| | +------+ | +-------------+ +-------+ | |track0|-|--->|field |--->|tractor| | +------+ | | | |\ | | | | filters | | \ | | +------+ | | and | | \ | | |track1|-|--->| transitions |--->|---o---|---> | +------+ | | | | / | | | | | | / | | +------+ | | | |/ | | |track2|-|--->| |--->| | | +------+ | +-------------+ +-------+ +----------+ So, we need to create the tractor first, and from that we obtain the multitrack and field objects. We can populate these and finally connect the tractor to a consumer. In essence, this is how it looks to the consumer: +-----------------------------------------------+ |tractor +--------------------------+ | | +----------+ | +-+ +-+ +-+ +-+ | | | |multitrack| | |f| |f| |t| |t| | | | | +------+ | | |i| |i| |r| |r| | | | | |track0|-|--->| |l|- ->|l|- ->|a|--->|a|\| | | | +------+ | | |t| |t| |n| |n| | | | | | | |e| |e| |s| |s| |\ | | | +------+ | | |r| |r| |i| |i| | \| | | |track1|-|- ->| |0|--->|1|--->|t|--->|t|-|--o---> | | +------+ | | | | | | |i| |i| | /| | | | | | | | | |o| |o| |/ | | | +------+ | | | | | | |n| |n| | | | | |track2|-|- ->| | |- ->| |--->|0|- ->|1|/| | | | +------+ | | | | | | | | | | | | | +----------+ | +-+ +-+ +-+ +-+ | | | +--------------------------+ | +-----------------------------------------------+ An example will hopefully clarify this. Let's assume that we want to provide a 'watermark' to our hello world example. We have already extended the example to play multiple clips, and now we will place a text based watermark, reading 'Hello World' in the top left hand corner: mlt_producer create_tracks( int argc, char **argv ) { // Create the tractor mlt_tractor tractor = mlt_tractor_new( ); // Obtain the field mlt_field field = mlt_tractor_field( tractor ); // Obtain the multitrack mlt_multitrack multitrack = mlt_tractor_multitrack( tractor ); // Create a composite transition mlt_transition transition = mlt_factory_transition( "composite", "10%/10%:15%x15%" ); // Create track 0 mlt_producer track0 = create_playlist( argc, argv ); // Create the watermark track - note we NEED loader for scaling here mlt_producer track1 = mlt_factory_producer( "loader", "pango" ); // Get the length of track0 mlt_position length = mlt_producer_get_playtime( track0 ); // Set the properties of track1 mlt_properties properties = mlt_producer_properties( track1 ); mlt_properties_set( properties, "text", "Hello\nWorld" ); mlt_properties_set_position( properties, "in", 0 ); mlt_properties_set_position( properties, "out", length - 1 ); mlt_properties_set_position( properties, "length", length ); mlt_properties_set_int( properties, "a_track", 0 ); mlt_properties_set_int( properties, "b_track", 1 ); // Now set the properties on the transition properties = mlt_transition_properties( transition ); mlt_properties_set_position( properties, "in", 0 ); mlt_properties_set_position( properties, "out", length - 1 ); // Add our tracks to the multitrack mlt_multitrack_connect( multitrack, track0, 0 ); mlt_multitrack_connect( multitrack, track1, 1 ); // Now plant the transition mlt_field_plant_transition( field, transition, 0, 1 ); // Close our references mlt_producer_close( track0 ); mlt_producer_close( track1 ); mlt_transition_close( transition ); // Return the tractor return mlt_tractor_producer( tractor ); } Now all we need do is to replace these lines in the main function: // Create a playlist mlt_producer world = create_playlist( argc, argv ); with: // Create a watermarked playlist mlt_producer world = create_tracks( argc, argv ); and we have a means to play multiple clips with a horribly obtrusive watermark - just what the world needed, right? ;-) Incidentally, the same thing could be achieved with the more trivial watermark filter inserted between the producer and the consumer. SECTION 3 - STRUCTURE AND DESIGN -------------------------------- Class Hierarchy: The mlt framework consists of an OO class hierarchy which consists of the following public classes and abstractions: mlt_properties mlt_frame mlt_service mlt_producer mlt_playlist mlt_tractor mlt_filter mlt_transition mlt_consumer mlt_deque mlt_pool mlt_factory Each class defined above can be read as extending the classes above and to the left. The following sections describe the properties, stacking/queuing and memory pooling functionality provided by the framework - these are key components and a basic understanding of these is required for the remainder of the documentation. mlt_properties: The properties class is the base class for the frame and service classes. It is designed to provide an efficient lookup table for various types of information, such as strings, integers, floating points values and pointers to data and data structures. All properties are indexed by a unique string. The most basic use of properties is as follows: // 1. Create a new, empty properties set; mlt_properties properties = mlt_properties_new( ); // 2. Assign the value "world" to the property "hello"; mlt_properties_set( properties, "hello", "world" ); // 3. Retrieve and print the value of "hello"; printf( "%s\n", mlt_properties_get( properties, "hello" ) ); // 4. Reassign "hello" to "world!"; mlt_properties_set( properties, "hello", "world!" ); // 5. Retrieve and print the value of "hello"; printf( "%s\n", mlt_properties_get( properties, "hello" ) ); // 6. Assign the value "0" to "int"; mlt_properties_set( properties, "int", "0" ); // 7. Retrieve and print the integer value of "int"; printf( "%d\n", mlt_properties_get_int( properties, "int" ) ); // 8. Assign the integer value 50 to "int2"; mlt_properties_set_int( properties, "int2", 50 ); // 9. Retrieve and print the double value of "int2"; printf( "%s\n", mlt_properties_get( properties, "int2" ) ); Steps 2 through 5 demonstrate that the "name" is unique - set operations on an existing "name" change the value. They also free up memory associated to the previous value. Note that it also possible to change type in this way too. Steps 6 and 7 demonstrate that the properties object handles deserialisation from strings. The string value of "0" is set, the integer value of 0 is retrieved. Steps 8 and 9 demonstrate that the properties object handles serialisation to strings. To show all the name/value pairs in a properties, it is possible to iterate through them: for ( i = 0; i < mlt_properties_count( properties ); i ++ ) printf( "%s = %s\n", mlt_properties_get_name( properties, i ), mlt_properties_get_value( properties, i ) ); Note that properties are retrieved in the order in which they are set. Properties are also used to hold pointers to memory. This is done via the set_data call: uint8_t *image = malloc( size ); mlt_properties_set_data( properties, "image", image, size, NULL, NULL ); In this example, we specify that the pointer can be retrieved from properties by a subsequent request to get_data: image = mlt_properties_get_data( properties, "image", &size ); or: image = mlt_properties_get_data( properties, "image", NULL ); if we don't wish to retrieve the size. Two points here: 1) The allocated memory remains after the properties object is closed unless you specify a destructor. In the case above, this can be done with: mlt_properties_set_data( properties, "image", image, size, free, NULL ); When the properties are closed, or the value of "image" is changed, the destructor is invoked. 2) The string value returned by mlt_properties_get is NULL. Typically, you wouldn't wish to serialise an image as a string, but other structures might need such functionality - you can specify a serialiser as the last argument if required (declaration is char *serialise( void * )). Properties also provides some more advanced usage capabilities. It has the ability to inherit all serialisable values from another properties object: mlt_properties_inherit( this, that ); It has the ability to mirror properties set on this on another set of properties: mlt_properties_mirror( this, that ); After this call, all serialisable values set on this are passed on to that. mlt_deque: Stacks and queues are essential components in the MLT framework. Being of a lazy disposition, we elected to implement a 'Double Ended Queue' (deque) - this encapsulates the functionality of both. The API of the deque is defined as follows: mlt_deque mlt_deque_init( ); int mlt_deque_count( mlt_deque this ); int mlt_deque_push_back( mlt_deque this, void *item ); void *mlt_deque_pop_back( mlt_deque this ); int mlt_deque_push_front( mlt_deque this, void *item ); void *mlt_deque_pop_front( mlt_deque this ); void *mlt_deque_peek_back( mlt_deque this ); void *mlt_deque_peek_front( mlt_deque this ); void mlt_deque_close( mlt_deque this ); The stacking operations are used in a number of places: * Reverse Polish Notation (RPN) image and audio operations * memory pooling The queuing operations are used in: * the consumer base class; * consumer implementations may require further queues. mlt_pool: The MLT framework provides memory pooling capabilities through the mlt_pool API. Once initilialised, these can be seen as a straightforward drop in replacement for malloc/realloc/free functionality. The background behind this API is that malloc/free operations are notoriously inefficient, especially when dealing with large blocks of memory (such as an image). On linux, malloc is optimised for memory allocations less than 128k - memory blocks allocated of these sizes or less are retained in the process heap for subsequent reuse, thus bypassing the kernel calls for repeated allocation/frees for small blocks of memory. However, blocks of memory larger than that require kernel calls and this has a detrimental impact on performance. The mlt_pool design is simply to hold a list of stacks - there is one stack per 2^n bytes (where n is between 8 and 31). When an alloc is called, the requested size is rounded to the next 2^n, the stack is retrieved for that size, and an item is popped or created if the stack is empty. Each item has a 'header', situated immediately before the returned address - this holds the 'stack' to which the item belongs. When an item is released, we retrieve the header, obtain the stack and push it back. Thus, from the programmers point of view, the API is the same as the traditional malloc/realloc/free calls: void *mlt_pool_alloc( int size ); void *mlt_pool_realloc( void *ptr, int size ); void mlt_pool_release( void *release ); mlt_frame: A frame object is essentially defined as: +------------+ |frame | +------------+ | properties | | image stack| | audio stack| +------------+ The life cycle of a frame can be represented as follows: +-----+----------------------+-----------------------+---------------------+ |Stage|Producer |Filter |Consumer | +-----+----------------------+-----------------------+---------------------+ | 0.0 | | |Request frame | +-----+----------------------+-----------------------+---------------------+ | 0.1 | |Receives request | | | | |Request frame | | +-----+----------------------+-----------------------+---------------------+ | 0.2 |Receives request | | | | |Generates frame for | | | | |current position | | | | |Increments position | | | +-----+----------------------+-----------------------+---------------------+ | 0.3 | |Receives frame | | | | |Updates frame | | +-----+----------------------+-----------------------+---------------------+ | 0.4 | | |Receives frame | +-----+----------------------+-----------------------+---------------------+ Note that neither the filter nor the consumer have any conception of 'position' until they receive a frame. Speed and position are properties of the producer, and they are assigned to the frame object when the producer creates it. Step 0.3 is a critical one here - if the filter determines that the frame is of interest to it, then it should manipulate the image and/or audio stacks and properties as required. Assuming that the filter deals with both image and audio, then it should push data and methods on to the stacks which will deal with the processing. This can be done with the mlt_frame_push_image and audio methods. In order for the filter to register interest in the frame, the stacks should hold: image stack: [ producer_get_image ] [ data1 ] [ data2 ] [ filter_get_image ] audio stack: [ producer_get_audio ] [ data ] [ filter_get_audio ] The filter_get methods are invoked automatically when the consumer invokes a get_image on the frame. +-----+----------------------+-----------------------+---------------------+ |Stage|Producer |Filter |Consumer | +-----+----------------------+-----------------------+---------------------+ | 1.0 | | |frame_get_image | +-----+----------------------+-----------------------+---------------------+ | 1.1 | |filter_get_image: | | | | | pop data2 and data1 | | | | | frame_get_image | | +-----+----------------------+-----------------------+---------------------+ | 1.2 |producer_get_image | | | | | Generates image | | | +-----+----------------------+-----------------------+---------------------+ | 1.3 | |Receives image | | | | |Updates image | | +-----+----------------------+-----------------------+---------------------+ | 1.4 | | |Receives image | +-----+----------------------+-----------------------+---------------------+ Obviously, if the filter isn't interested in the image, then it should leave the stack alone, and then the consumer will retrieve its image directly from the producer. Similarly, audio is handled as follows: +-----+----------------------+-----------------------+---------------------+ |Stage|Producer |Filter |Consumer | +-----+----------------------+-----------------------+---------------------+ | 2.0 | | |frame_get_audio | +-----+----------------------+-----------------------+---------------------+ | 2.1 | |filter_get_audio: | | | | | pop data | | | | | frame_get_audio | | +-----+----------------------+-----------------------+---------------------+ | 2.2 |producer_get_audio | | | | | Generates audio | | | +-----+----------------------+-----------------------+---------------------+ | 2.3 | |Receives audio | | | | |Updates audio | | +-----+----------------------+-----------------------+---------------------+ | 2.4 | | |Receives audio | +-----+----------------------+-----------------------+---------------------+ And finally, when the consumer is done with the frame, it should close it. Note that a consumer may not evaluate both image and audio for any given frame, especially in a realtime environment. See 'Realtime Considerations' below. By default, a frame has the following properties: +------------------+------------------------------------+------------------+ |Name |Description |Values | +------------------+------------------------------------+------------------+ |_position |The producers frame position |0 to n | +------------------+------------------------------------+------------------+ |_speed |The producers speed |double | +------------------+------------------------------------+------------------+ |image |The generated image |NULL or pointer | +------------------+------------------------------------+------------------+ |alpha |The generated alpha mask |NULL or pointer | +------------------+------------------------------------+------------------+ |width |The width of the image | | +------------------+------------------------------------+------------------+ |height |The height of the image | | +------------------+------------------------------------+------------------+ |normalised_width |The normalised width of the image |720 | +------------------+------------------------------------+------------------+ |normalised_height |The normalised height of the image |576 or 480 | +------------------+------------------------------------+------------------+ |progressive |Indicates progressive/interlaced |0 or 1 | +------------------+------------------------------------+------------------+ |top_field_first |Indicates top field first |0 or 1 | +------------------+------------------------------------+------------------+ |audio |The generated audio |NULL or pointer | +------------------+------------------------------------+------------------+ |frequency |The frequency of the audio | | +------------------+------------------------------------+------------------+ |channels |The channels of the audio | | +------------------+------------------------------------+------------------+ |samples |The samples of the audio | | +------------------+------------------------------------+------------------+ |aspect_ratio |The sample aspect ratio of the image|double | +------------------+------------------------------------+------------------+ |test_image |Used to indicate no image available |0 or 1 | +------------------+------------------------------------+------------------+ |test_audio |Used to indicate no audio available |0 or 1 | +------------------+------------------------------------+------------------+ The consumer can attach the following properties which affect the default behaviour of a frame: +------------------+------------------------------------+------------------+ |test_card_producer|Synthesise test images from here |NULL or pointer | +------------------+------------------------------------+------------------+ |consumer_aspect_ |Apply this aspect ratio to the test |double | |ratio |card producer | | +------------------+------------------------------------+------------------+ |rescale.interp |Use this scale method for test image|"string" | +------------------+------------------------------------+------------------+ While most of these are mainly self explanatory, the normalised_width and normalised_height values require a little explanation. These are required to ensure that effects are consistently handled as PAL or NTSC, regardless of the consumers or producers width/height image request. The test_image and audio flags are used to determine when images and audio should be synthesised. Additional properties may be provided by the producer implementation, and filters, transitions and consumers may add additional properties to communicate specific requests. These are documented in modules.txt. The complete API for the mlt frame is as follows: mlt_frame mlt_frame_init( ); mlt_properties mlt_frame_properties( mlt_frame this ); int mlt_frame_is_test_card( mlt_frame this ); int mlt_frame_is_test_audio( mlt_frame this ); double mlt_frame_get_aspect_ratio( mlt_frame this ); int mlt_frame_set_aspect_ratio( mlt_frame this, double value ); mlt_position mlt_frame_get_position( mlt_frame this ); int mlt_frame_set_position( mlt_frame this, mlt_position value ); int mlt_frame_get_image( mlt_frame this, uint8_t **buffer, mlt_image_format *format, int *width, int *height, int writable ); uint8_t *mlt_frame_get_alpha_mask( mlt_frame this ); int mlt_frame_get_audio( mlt_frame this, int16_t **buffer, mlt_audio_format *format, int *frequency, int *channels, int *samples ); int mlt_frame_push_get_image( mlt_frame this, mlt_get_image get_image ); mlt_get_image mlt_frame_pop_get_image( mlt_frame this ); int mlt_frame_push_frame( mlt_frame this, mlt_frame that ); mlt_frame mlt_frame_pop_frame( mlt_frame this ); int mlt_frame_push_service( mlt_frame this, void *that ); void *mlt_frame_pop_service( mlt_frame this ); int mlt_frame_push_audio( mlt_frame this, void *that ); void *mlt_frame_pop_audio( mlt_frame this ); void mlt_frame_close( mlt_frame this ); mlt_service: The service base class extends properties and allows 0 to m inputs and 0 to n outputs and is represented as follows: +-----------+ - ->| |- -> - ->| Service |- -> - ->| | +-----------+ | properties| +-----------+ Descendents of service impose restrictions on how inputs and outputs can be connected and will provide a basic set of properties. Typically, the service instance is encapsulated by the descendent in order for it to ensure that its connection rules are followed. A service does not define any properties when constructed. It should be noted that producers, filters and transitions my be serialised (say, via the xml consumer), and care should be taken to distinguish between serialisable and transient properties. The convention used is to prefix transient properties with an underscore. The public interface is defined by the following functions: int mlt_service_init( mlt_service this, void *child ); mlt_properties mlt_service_properties( mlt_service this ); int mlt_service_connect_producer( mlt_service this, mlt_service producer, int index ); int mlt_service_get_frame( mlt_service this, mlt_frame_ptr frame, int index ); void mlt_service_close( mlt_service this ); Typically, only direct descendents of services need invoke these methods and developers are encouraged to use those extensions when defining new services. mlt_producer: A producer has 0 inputs and 1 output: +-----------+ | | | Producer |---> | | +-----------+ | service | +-----------+ A producer provides an abstraction for file readers, pipes, streams or any other image or audio input.

Directories ----------- The directory heirarchy is defined as follows: + demo - A selection of samples to show off capabilities. + docs - Location of all documentation + src - All project source is provided here + framework - The mlt media framework + modules - All services are defined here + avformat - libavformat dependent services + core - Independent MLT services + dv - libdv dependent services + gtk2 - pango and pixbuf dependent services + normalize - audio normalisation functions (**) + plus - throwaway silliness + resample - libresample dependent services (**) + sdl - SDL dependent services + vorbis - vorbis dependenent services + xml - XML (de)serialization services + xine - Xine-derived sources (**) + melt - A media playing test application (**) + tests - Reserved for regression and unit tests Additional subdirectories may be nested below those shown and should be documented in their parent. (*) Not posted to CVS due to licensing issues. (**) Contains GPL dependencies or code. Dependencies ------------ The MLT core is dependent on: * a C99 compliant C compiler * posix threading * standard posix libraries The MLT applications and libraries provided are all dependent on the core. The modules have the following dependencies: ----------- ---------------------------------------------------------- MODULE DESCRIPTION ----------- ---------------------------------------------------------- avformat Provided from ffmpeg CVS and compiled as a shared library. URL: http://ffmpeg.sf.net ----------- ---------------------------------------------------------- dv libdv 0.102 or later. URL: http://libdv.sf.net ----------- ---------------------------------------------------------- gtk2 GTK2 and associated dependencies. URL: http://www.gtk.org ----------- ---------------------------------------------------------- resample libsamplerate 0.15 or later URL: http://www.mega-nerd.com/SRC/ (GPL) ----------- ---------------------------------------------------------- sdl SDL 1.2 or later. URL: http://www.libsdl.org ----------- ---------------------------------------------------------- vorbis libvorbis 1.0.1 or later. URL: http://www.vorbis.com/ ----------- ---------------------------------------------------------- xml libxml2 2.5 or later. URL: http://www.xmlsoft.org/ ----------- ---------------------------------------------------------- Configuration ------------- Configuration is triggered from the top level directory via a ./configure script. Each source bearing subdirectory shown above have their own configure script which are called automatically from the top level. Typically, new modules can be introduced without modification to the configure script and arguments are accepted and passed through to all subdirectories. More information on usage is found by running: ./configure --help NB: This script must be run to register new services after a CVS checkout or subsequent update. Compilation ----------- Makefiles are generated during configuration and these are based on a per directory template which must be provided by the developer. Testing ------- To execute the mlt tools without installation, or to test a new version on a system with an already installed mlt version, you should run: . setenv NB: This applies to your current shell only and it assumes sh or bash. Installation ------------ The install is triggered by running make install from the top level directory. The framework produces a single shared object which is installed in $prefix/lib/ and public header files which are installed in $prefix/include/mlt/framework. The modules produce a shared object per module and update text files containing a list of modules provided by this build. These are installed in $prefix/share/mlt/modules. It is at the discretion of the module to install additional support files. To allow the development of external components, mlt-config and scripts are generated and installed in $prefix/bin. After install, only those modules listed are usable by the server. No module is loaded unless explicitly requested via server configuration or usage. External modules are also placed in this $prefix/share/mlt/modules, and the installation of those must modify the text file accordingly before they will be considered at runtime. Development ----------- All compilation in the project has {top-level-dir}/src on the include path. All headers are included as: #include All external modules have {prefix}/include/mlt on the include path. All headers should also be included as: #include This allows migration of source between external and internal modules. The configuration and Makefile template requirements will require attention though. mlt-0.9.0/docs/melt.1000066400000000000000000000057241215300731300142720ustar00rootroot00000000000000.\" DO NOT MODIFY THIS FILE!

It can be thought of as a powerful, if somewhat obscure, multitrack command line oriented video editor. The following details the usage of the tool and as a result, provides a lot of insight into the workings of the MLT framework. Usage: melt [options] [producer [name=value]* ]+ Options: -attach filter[:arg] [name=value]* Attach a filter to the output -attach-cut filter[:arg] [name=value]* Attach a filter to a cut -attach-track filter[:arg] [name=value]* Attach a filter to a track -attach-clip filter[:arg] [name=value]* Attach a filter to a producer -audio-track | -hide-video Add an audio-only track -blank frames Add blank silence to a track -consumer id[:arg] [name=value]* Set the consumer (sink) -debug Set the logging level to debug -filter filter[:arg] [name=value]* Add a filter to the current track -group [name=value]* Apply properties repeatedly -help Show this message -jack Enable JACK transport synchronization -join clips Join multiple clips into one cut -mix length Add a mix between the last two cuts -mixer transition Add a transition to the mix -null-track | -hide-track Add a hidden track -profile name Set the processing settings -progress Display progress along with the position -remove Remove the most recent cut -repeat times Repeat the last cut -query List all of the registered services -query "consumers" | "consumer"=id List consumers or show info about one -query "filters" | "filter"=id List filters or show info about one -query "producers" | "producer"=id List producers or show info about one -query "transitions" | "transition"=id List transitions or show info about one -query "profiles" | "profile"=id List profiles or show info about one -query "presets" | "preset"=id List presets or show info about one -query "formats" List audio/video formats -query "audio_codecs" List audio codecs -query "video_codecs" List video codecs -serialise [filename] Write the commands to a text file -silent Do not display position/transport help -split relative-frame Split the last cut into two cuts -swap Rearrange the last two cuts -track Add a track -transition id[:arg] [name=value]* Add a transition -verbose Set the logging level to verbose -version Show the version and copyright message -video-track | -hide-audio Add a video-only track General rules: 1. Order is incredibly important; 2. Error checking on command line parsing is weak; 3. Please refer to services.txt for details on services available; 4. The MLT framework, from which melt has inherited its naming convention, is very mlt-centric. Producers produce MLT frame objects and consumers consume MLT frame objects. The distinction is important - a DV producer does not produce DV, it produces MLT frames from a DV source, and similarly a DV consumer does not consume DV, it consumes MLT frames and produces DV frames. Terminology: 'Producers' typically refer to files but may also indicate devices (such as dv1394 input or video4linux). Hence, the more generic term is used [the more generic usage is out of scope for now...]. 'Filters' are frame modifiers - they always guarantee that for every frame they receive, they output *precisely* one frame. Never more, never less, ever. Nothing says that a filter cannot generate frames though 'Transitions' collect frames from two tracks (a and b) and output 1 modified frame on their 'a track', and 1 unmodified frame on their 'b track'. Never more, never less, ever. 'Consumers' collect frames from a producer, do something with them and destroy them. Collectively, these are known as 'services'. All services have 'properties' associated to them. These are typically defaulted or evaluated and may be overriden on a case by case basis. All services except consumers obey in and out properties. Consumers have no say in the flow of frames [though they may give the illusion that they do]. They get frames from a connected producer, use them, destroy them and get more. Basics: To play a file with the default SDL PAL consumer, usage is: $ melt file Note that 'file' can be anything that melt has a known 'producer' mapping for (so this can be anything from .dv to .txt). You can also specify the producer directly, for example: $ melt avformat:file.mpeg Would force the direct use of avformat for loading the file. Properties: Properties can be assigned to the producer by adding additional name=value pairs after the producer: $ melt file in=50 out=100 something="something else" Note that while some properties have meaning to all producers (for example: in, out and length are guaranteed to be valid for all, though typically, length is determined automatically), the validity of others are dependent on the producer - however, properties will always be assigned and silently ignored if they won't be used. Multiple Files: Multiple files of different types can be used: $ melt a.dv b.mpg c.png Properties can be assigned to each file: $ melt a.dv in=50 out=100 b.mpg out=500 c.png out=500 MLT will take care of 'normalising' the output of a producer to ensure that the consumer gets what it needs. So, in the case above, the mlt framework will ensure that images are rescaled and audio resampled to meet the requirements of your configuration (which, by default, will be PAL). See 'Appendix A: Normalisation Rules' below. Filters: Filters are frame modifiers - they can change the contents of the audio or the images associated to a frame. $ melt a.dv -filter greyscale As with producers, properties may be specified on filters too. Again, in and out properties are common to all, so to apply a filter to a range of frames, you would use something like: $ melt a.dv -filter greyscale in=0 out=50 Again, filters have their own set of rules about properties and will silently ignore properties that do not apply. Groups: The -group switch is provided to force default properties on the following 'services'. For example: $ melt -group in=0 out=49 clip* would play the first 50 frames of all clips that match the wild card pattern. Note that the last -group settings also apply to the following filters, transitions and consumers, so: $ melt -group in=0 out=49 clip* -filter greyscale is *probably not* what you want (ie: the greyscale filter would only be applied to the first 50 frames). To shed the group properties, you can use any empty group: $ melt -group in=0 out=49 clip* -group -filter greyscale Attached Filters: As described above, the -filter switch applies filters to an entire track. To localise filters to a specific clip on a track, you have to know information about the lengths of the clip and all clips leading up to it. In practise, this is horrifically impractical, especially at a command line level (and not even that practical from a programing point of view...). The -attach family of switches simplify things enormously. By default, -attach will attach a filter to the last service created, so: $ melt clip1.dv clip2.dv -attach greyscale clip3.dv would only apply the filter to clip2.dv. You can further narrow down the area of the effect by specifying in/out points on the attached filter. This might seem simple so far, but there is a catch... consider the following: $ melt clip1.dv -attach watermark:+hello.txt -attach invert The second attached filter is actually attached to the watermark. You might think, yay, nice (and it is :-)), but, it might not be what you want. For example you might want to attach both to clip1.dv. To do that, you can use: $ melt clip1.dv -attach-cut watermark:+hello.txt -attach-cut invert As you shall see below, there are still another couple of gotchas associated to -attach, and even another variant :-). Mixes: The -mix switch provides the simplest means to introduce transitions between adjacent clips. For example: $ melt clip1.dv clip2.dv -mix 25 -mixer luma -mixer mix:-1 would provide both an audio and video transition between clip1 and clip2. This functionality supercedes the enforced use of the -track and -transition switches from earlier versions of melt and makes life a lot easier :-). These can be used in combination, so you can for example do a fade from black and to black using the following: $ melt colour:black out=24 clip1.dv -mix 25 -mixer luma \ colour:black out=24 -mix 25 -mixer luma while this may not be immediately obvious, consider what's happening as the command line is being parsed from left to right: Input: Track ----------------------- ----------------------------------------------------- colour:black out=24 [black] clip1.dv [black][clip1.dv] -mix 25 [black+clip1.dv][clip1.dv] -mixer luma [luma:black+clip1.dv][clip1.dv] colour:black out=24 [luma:black+clip1.dv][clip1.dv][black] -mix 25 [luma:black+clip1.dv][clip1.dv][clip1.dv+black] -mixer luma [luma:black+clip1.dv][clip1.dv][luma:clip1.dv+black] Obviously, the clip1.dv instances refer to different parts of the clip, but hopefully that will demonstrate what happens as we construct the track. You will find more details on the mix in the framework.txt. Mix and Attach: As noted, -attach normally applies to the last created service - so, you can attach a filter to the transition region using: $ melt clip1.dv clip2.dv -mix 25 -mixer luma -attach watermark:+Transition.txt Again, nice, but take care - if you want the attached filter to be associated to the region following the transition, use -attach-cut instead. Splits, Joins, Removes and Swaps: COMPLEX - needs simplification.... Introducing Tracks and Blanks: So far, all of the examples have shown the definition of a single playlist, or more accurately, track. When multiple tracks exist, the consumer will receive a frame from the 'highest numbered' track that is generating a non-blank frame. It is best to visualise a track arrangement, so we'll start with an example: $ melt a.dv -track b.dv in=0 out=49 This can be visualised as follows: +------------------+ |a | +-------+----------+ |b | +-------+ Playout will show the first 50 frames of b and the 51st frame shown will be the 51st frame of a. This rule also applies to audio only producers on the second track, for example, the following would show the video from the a track, but the audio would come from the second track: $ melt a.dv -track b.mp3 in=0 out=49 To have the 51st frame be the first frame of b, we can use the -blank switch: $ melt a.dv out=49 -track -blank 49 b.dv Which we can visualise as: +-------+ |a | +-------+-------------------+ |b | +-------------------+ Now playout will continue as though a and b clips are on the same track (which on its own, is about as useful as reversing the process of slicing bread). Transitions: Where tracks become useful is in the placing of transitions. Here we need tracks to overlap, so a useful multitrack definition could be given as: $ melt a.dv out=49 \ -track \ -blank 24 b.dv \ -transition luma in=25 out=49 a_track=0 b_track=1 Now we're cooking - our visualisation would be something like: +-------+ |a | +---+---+--------------+ |b | +------------------+ Playout will now show the first 25 frames of a and then a fade transition for 25 frames between a and b, and will finally playout the remainder of b. Reversing a Transition: When we visualise a track definition, we also see situations like: +-------+ +----------+ |a1 | |a2 | +---+---+--------------+----+-----+ |b | +-----------------------+ In this case, we have two transitions, a1 to b and b to a2. In this scenario, we define a command line as follows: $ melt a.dv out=49 -blank 49 a2.dv \ -track \ -blank 24 b.dv out=99 \ -transition luma in=25 out=49 a_track=0 b_track=1 \ -transition luma in=100 out=124 reverse=1 a_track=0 b_track=1 Serialisation: Melt has a built in serialisation mechanism - you can build up your command, test it via any consumer and then add a -serialise file.melt switch to save it. The saved file can be subsequently used as a clip by melt or other MLT applications. Take care though - paths to files are saved as provided on the command line.... A more expressive serialisation can be obtained with the xml consumer - this will provide an xml document which can be used freely in melt and other MLT applications. See mlt-xml.txt for more information. Missing Features: Some filters/transitions should be applied on the output frame regardless of which track it comes from - for example, you might have a 3rd text track or a watermark which you want composited on every frame, and of course, there's the obscure filter.... melt only supports this in two invocations - as a simple example: $ melt a.dv -track -blank 100 b.dv -consumer xml:basic.mlt $ melt basic.mlt -filter watermark:watermark.png mlt-0.9.0/docs/mlt++.txt000066400000000000000000000404311215300731300147240ustar00rootroot00000000000000MLT++ ----- This mlt sub-project provides a C++ wrapping for the MLT library. Usage ----- Use the following definitions in a Makefile to compile and link with mlt++: CXXFLAGS=`pkg-config --cflags mlt-framework` -Wall LDFLAGS=-lmlt++ `pkg-config --libs mlt-framework` Include files for the classes can either be explicitly included, ie: #include etc Or you can include all using: #include All definitions are placed in an Mlt namespace, and adhere closely to the C naming convention. Mappings always follow the pattern: Factory methods: mlt_factory_init ==> Mlt::Factory::init mlt_factory_producer ==> Mlt::Factory::producer mlt_factory_filter ==> Mlt::Factory::filter mlt_factory_transition ==> Mlt::Factory::transition mlt_factory_consumer ==> Mlt::Factory::consumer mlt_factory_close ==> Mlt::Factory::close NB: Factory usage for service construction is optional. Types: mlt_properties ==> Mlt::Properties mlt_frame ==> Mlt::Frame mlt_service ==> Mlt::Service mlt_producer ==> Mlt::Producer mlt_filter ==> Mlt::Filter mlt_transition ==> Mlt::Transition mlt_consumer ==> Mlt::Consumer Methods: mlt_type_method ==> Mlt::Type.method ie: mlt_playlist_append ==> Mlt::Playlist.append Parent methods are available directly on children. Additionally, you can specify: using namespace Mlt; To avoid the enforced use of the Mlt:: prefix. Enumerators and macros are reused directly from the C library. Class Hierarchy --------------- The currently mapped objects are shown in the following hierarchy: Factory Properties Frame Service Consumer Field Filter Multitrack Producer Playlist Tractor Transition Special Cases ------------- Care should be taken with wrapper objects. Taking, as an example, the C function that returns the immediate consumer of a service: mlt_service mlt_service_consumer( mlt_service ); This maps to: Mlt::Service *Mlt::Service.consumer( ); Note that you get an object back - it is never the original c++ object, but a wrapping object. This is done to keep consistency with the C api which may instantiate C instances - therefore it cannot be assumed that a C++ object exists for all mlt service instances. As such, it is mandatory that you delete these objects. The original will not be affected. However, all other modifications (to properties or its state of connection) will be reflected in the original object. This approach excludes the use of RTTI to determine the real type of the object - this can only be done by parsing the objects properties. Objects may be invalid - always use the is_valid method to check validity before use. Limitations ----------- The mechanisms for the definition of new services are deliberately excluded from the C++ wrappings - this is done to ensure that service networks constructed can be serialised and used by existing applications which are based on the C API (such as melted). Hello World ----------- The mlt++ wrapper is a c++ wrapper for the mlt C library. As such, it provides clean C++ access to the underlying library. An example of use is as follows: #include using namespace Mlt; int main( void ) { Factory::init( ); Producer p( "pango:", "Hello World" ); Consumer c( "sdl" ); c.connect( p ); c.run( ); return 0; } This is a fairly typical example of mlt++ usage - create a 'producer' (an object which produces 'frames'), create a 'consumer' (an object which consumes frames), connect them together, start the consumer and wait until done (here we just wait for the user to close the window). In this case, we construct a window as a consumer using the 'sdl' consumer (SDL is a standard portable library which provides platform independent access to accelerated video display and audio) and use the 'pango' producer to generate frames with the words 'Hello World' (pango is a library from the gtk toolkit). The main point of this example is to show that mlt uses existing libraries to provide its functionality - this keeps the framework itself very small. Note that mlt is designed to be housed in GUI or server type applications - typically, applications don't wait around for the consumer to be stopped in the manner shown. So far, we've introduced the Producer and Consumer mlt classes. We'll cover each of these in more detail later in the tutorial, but for now, we'll briefly cover the remaining classes. Playlists --------- Another simple class is the Playlist - this is direct extension of Producer and it allows you to maintain a list of producer objects. As a simple example of the Playlist in action, we'll convert the example above into an application which plays multiple video or audio files. #include using namespace Mlt; int main( int argc, char **argv ) { Factory::init( ); Playlist list; for ( int i = 1; i < argc; i ++ ) { Producer p( argv[i] ); if ( p.is_valid( ) ) list.append( p ); } Consumer c( "sdl" ); c.connect( list ); c.run( ); return 0; } Now you can run the program as: ./player *.avi *.mp3 *.jpg etc In this case, we construct a playlist by simply appending producers to it. Notice that although the scope of the Producer is limited to the inner for loop, we can safely add it to the playlist - this is due to the fact that all mlt objects maintain reference counts and no object is really destroyed until all the references are gone. In this case, when the list object goes out of scope, all the producers we created will automatically be destroyed. Filters ------- So far, we've shown how you can load and play media. We've given a brief intro to the Playlist container, now it's time to start manipulating things... For the next example, I'll add a 'watermark' to the video - a watermark is used by broadcasters to brand the channel and normally consists of a logo of some sort. We'll just use some black text on a partially transparent red background. #include using namespace Mlt; int main( int argc, char **argv ) { Factory::init( ); Playlist list; for ( int i = 1; i < argc; i ++ ) { Producer p( argv[i] ); if ( p.is_valid( ) ) list.append( p ); } Filter f( "watermark", "pango:" ); f.set( "producer.text", "MLT++" ); f.set( "producer.fgcolour", "0x000000ff" ); f.set( "producer.bgcolour", "0xff000080" ); list.attach( f ); Consumer c( "sdl" ); c.connect( list ); c.run( ); return 0; } Notice that the watermark filter reuses the 'pango' producer we showed in the first example. In fact, you could use any producer here - if you wanted to use a graphic or a video, you would just construct the filter with a full path to that as the second argument. We manipulate the filter using the set method - this method was also shown in the first example. Finally, we attach the filter to the playlist. This ensure that all frames that are obtained from the playlist are watermarked. Cuts ---- When you add a clip to a playlist, the a cut object is created - this is merely a wrapper for the producer, spanning the specified in and out points. Whenever you retrieve a clip from a playlist, you will always get a cut object. This allows you to attach filters to a specific part of a producer and should the position of the cut in the playlist change, then the filter will remain correctly associated to it. A producer and a cut are generally identical in behaviour, but should you need to distinguish between them, you can use: if ( producer.is_cut( ) ) and to retrieve the parent of a cut, you can use: Producer parent = producer.parent_cut( ); Filters that are attached directly to a parent are executed before any filters attached to the cut. Tractor ------- A tractor is an object that allows the manipulation of multiple video and audio tracks. Stepping away from the player example we've been tinkering with for a minute, let's assume we want to do something like dub a video with some audio. This a very trivial thing to do: Tractor *dub( char *video_file, char *audio_file ) { Tractor *tractor = new Tractor( ); Producer video( video_file ); Producer audio( audio_file ); tractor->set_track( video, 0 ); tractor->set_track( audio, 1 ); return tractor; } That's all that needs to be done - you can now connect the returned object to a consumer, or add it to a playlist, or even apply it as a track to another tractor. Transition ---------- Let's now assume we want to mix the audio between two tracks - to do this, we need to introduce the concept of a transition. A transition in mlt is a service which combines frames from two producers to produce a new frame. Tractor *mix( char *video_file, char *audio_file ) { Tractor *tractor = new Tractor( ); Transition mix( "mix" ); Producer video( video_file ); Producer audio( audio_file ); tractor.set_track( video, 0 ); tractor.set_track( audio, 1 ); tractor.field.plant_transition( mix, 0, 1 ); return tractor; } The tractor returned will now mix the audio from the original video and the audio. Mix --- There is a convenience function which simplifies the process of applying transitions betwee adjacent cuts on a playlist. This is often preferable to use over the constuction of your own tractor and transition set up. To apply a 25 frame luma transition between the first and second cut on the playlist, you could use: Transition luma; playlist.mix( 0, 25, luma ); Events ------ Typically, applications need to be informed when changes occur in an mlt++ object. This facilitates application services such as undo/redo management, or project rendering in a timeline type widget and many other types of operations which an application needs. As an example, consider the following: class Xml { private: Consumer consumer; Tractor &tractor; public: Xml( MltTractor &tractor ) : tractor( tractor ), consumer( "xml" ) { consumer.connect( tractor ); tractor.listen( tractor, "producer-changed", ( mlt_listener )Xml::listener ); } static void listener( Properties *tractor, Xml *object ) { object->activate( ); } void activate( ) { consumer.start( ); } }; Now, each time the tractor is changed, the XML representation is output to stderr. That's All Folks... ------------------- And that, believe it or not, is a fairly complete summary of the classes you'll typically be interfacing with in mlt++. Obviously, there's a little more to it than this - a couple of intrisinc classes have been glossed over (notably, the Properties and Service base classes). The next section will cover all of the above, but in much more detail... DIGGING DEEPER -------------- The previous section was designed to give you a whistle stop tour through the major framework classes. This section will take you through the scenic route. Introducing Base Classes ------------------------ Services in mlt are the collective noun for Producers, Filters, Transitions and Consumer. A Service is also the base class from which all of these classes extend. It provides the basic connectivity which has been shown throughout the examples in the previous section. Properties are the main way in which we communicate with the Services - essentially, it provides get/set methods for named values. All services extend Properties. Properties ---------- Properties provide the general mechanism for communicating with Services - through the Properties interface, we are able to manipulate and serialise a services state. For example, to dump all the properties to stdout, you can use something like: void dump( Properties &properties ) { for ( int i = 0; i < properties.count( ); i ++ ) cout << Properties.get_name( i ) << " = " << Properties.get( i ) << endl; } Note that the properties object handles type conversion, so the following is acceptable: properties.set( "hello", "10.5" ); int hello_int = properties.get_int( "hello" ); double hello_double = properties.get_double( "hello" ); A couple of convenience methods are provide to examine or serialise property objects. For example: properties.debug( ); will report all serialisable properties on stderr, in the form: Object: [ ref=1, in=0, out=0, track=0, u=75, v=150, _unique_id=15, mlt_type=filter, mlt_service=sepia ] Services -------- Typically, all the services are constructed via the specific classes constructor. Often, you will receive Service objects rather than their specific type. In order to access the extended classes interface, you will need to create a reference. For example, given an arbitrary Service object, you can determine its type by using the type method - this will return a 'service_type' which has values of producer_type, filter_type etc. Alternatively, you can create a wrapping object and check on its validity. bool do_we_have_a_producer( Service &service ) { Producer producer( service ); return producer.is_valid( ); } Events ------ Servers and MLT XML Docs ------------------------ For various reasons, you might want to serialise a producer to a string. To do this, you just need to specify a property to write to: Consumer xml( "xml", "buffer" ); xml.connect( producer ); xml.start( ); buffer = xml.get( "buffer" ); You can use any name you want, and you can change it using the "resource" property. Any name with a '.' in it is considered to be a file. Hence, you can use a xml consumer to store multiple instances of the same MLT object - useful if you want to provide undo/redo capabilities in an editing application. Should you receive an XML document as a string, and you want to send it on to a server, you can use: Consumer client( "mvsp", "localhost:5250" ); client.set( "xml", buffer ); client.start( ); If you need to obtain an MLT object from a XML string: Producer producer( "xml-string", buffer ); The following shows a working example of an extended server: class ShotcutServer : public Melted { public: ShotcutServer( char *id, int port ) : Melted( id, port ) { } void set_receive_doc( bool doc ) { set( "push-parser-off", doc ); } // Reject all commands other than push/receive Response *execute( char *command ) { mvsp_response response = mvsp_response_init( ); mvsp_response_set_error( response, 400, "Not OK" ); return new Response( response ); } // Push document handler Response *received( char *command, char *doc ) { mvsp_response response = mvsp_response_init( ); // Use doc in some way and assign Response if ( doc != NULL ) mvsp_response_set_error( response, 200, "OK" ); return new Response( response ); } // Push service handler Response *push( char *command, Service *service ) { mvsp_response response = mvsp_response_init( ); // Use service in some way and assign Response if ( service != NULL ) mvsp_response_set_error( response, 200, "OK" ); return new Response( response ); } }; NB: Should you be incorporating this into a GUI application, remember that the execute, received and push methods are invoked from a thread - make sure that you honour the locking requirements of your GUI toolkit before interacting with the UI. mlt-0.9.0/docs/mlt-xml.txt000066400000000000000000000516701215300731300154030ustar00rootroot00000000000000MLT XML Schema Documentation Copyright (C) 2004-2009 Ushodaya Enterprised Limited Authors: Charles Yates Last Revision: 2009-05-08 MLT XML ------- Preamble: This is the MLT projects XML serialisation/deserialisation format - as such, it closely mirrors the internal structure of the MLT API. If you just want to go straight to the DTD, then see mlt/src/modules/xml/mlt-xml.dtd, which gets installed at $(prefix)/share/mlt/modules/xml/mlt-xml.dtd. Currently, the XML parser is non-validating. Introduction: A MLT XML document is essentially a list of 'producers' - a producer is an mlt object which generates mlt frames (images and associated audio samples). There are 3 types of producer: * Basic Producers - these are typically file or device oriented feeds; * Playlists - these are arrangements of multiple producers; * Multitracks - these are the fx encapsulators. In the mlt model, producers are created and attached to 'consumers' - consumers are software playback components (such as SDL), or wrappers for hardware drivers (such as sdi) or even the XML serialising consumer itself (the latter doesn't receive frames - it merely interrogates the connected producer for its configuration). Although MLT XML was defined as a serialisation mechanism for instantiated MLT components, this document will concentrate on the hand authoring of MLT XML documents. Rules: As shall become apparent through the remainder of this document, the basic tenet of MLT XML authoring is to organise the document in the following manner: 1) create producer elements for each unique media clip in the project; 2) create playlists for each track; 3) create a multitrack and specify filters and transitions; 4) adding global filters. While other uses of MLT XML exist, the approach taken here is to maximise efficiency for complex projects. Basic Producers: The simplest MLT XML document is: clip1.dv The XML wrapping is of course superfluous here - loading this document with MLT is identical to loading the clip directly. Of course, you can specify additional properties. For example, consider an MPEG file with multiple soundtracks - you could define a MLT XML document to ensure that the second audio track is loaded: clip1.mpeg 1 NB: This relies on the mpeg being handled by the avformat producer, rather than the mcmpeg one. See services.txt for more details. A more useful example comes with the pango producer for a text producer. TODO: pango example... Notes: 1) It is better not to specify in/out points when defining basic producers as these can be specified in the playlists. The reasoning is that in/out restricts the amount of the clip available, and could lead to the same clip being loaded multiple times if you need different regions of the clip elsewhere; 2) A MLT XML doc can be specified as a resource, so XML docs can naturally encapsulate other XML docs. Playlists: Playlists provide a 'collection' structure for producers. These can be used to define 'tracks' in the multitrack approach, or simple playlists for sequential, single track playout. As an example, the following defines two basic producers and a playlist with 3 items: clip1.dv clip2.dv Here we see how the playlist defines the in/out points of the basic producers. Notes: 1) All in/out points are absolute frame positions relative to the producer being appended to the playlist; 2) MLT XML documents are currently authored for a specific normalisation; 3) The last 'producer' in the document is the default for play out; 4) Playlists can reference the same producer multiple times. In/out regions do not need to be contiguous - duplication and skipping is acceptable. Interlude - Introducing Multitracks: So far we've defined basic producers and playlists/tracks - the tractor is the element that allows us to arrange our tracks and specify filters and transitions. Similarly to a playlist, a tractor is a container. Note that MLT doesn't see a filter or a transition as a producer in the normal sense - filters and transitions are passive when it comes to seeking. Internally, seeks are carried out on the producers. This is an important point - MLT does not follow a traditional graph oriented model. Visualising an MLT tractor and it's interaction with the consumer will assist here: +----------------------------------------------+ |tractor | | +----------+ +-+ +-+ +-+ +-+ | | |multitrack| |f| |f| |t| |t| | | | +------+ | |i| |i| |r| |r| | | | |track0|-|--->|l|- ->|l|- ->|a|--->|a|\ | | | +------+ | |t| |t| |n| |n| \ | | | | |e| |e| |s| |s| \ | | | +------+ | |r| |r| |i| |i| \ | +--------+ | | |track1|-|- ->|0|--->|1|--->|t|--->|t|-----|--->|consumer| | | +------+ | | | | | |i| |i| / | +--------+ | | | | | | | |o| |o| / | ^ | | +------+ | | | | | |n| |n| / | | | | |track2|-|- ->| |- ->| |--->|0|- ->|1|/ | | | | +------+ | | | | | | | | | | | | +----------+ +-+ +-+ +-+ +-+ | | +----------------------------------------------+ | ^ | | | +-----------+ | |APPLICATION|--------------------------------------------+ +-----------+ Internally, all frames from all tracks pass through all the filters and transitions - these are told which tracks to deal and which regions of the tracks to work on. Note that the application communicates with the producer - it can alter playback speed, position, or even which producer is connected to which consumer. The consumer receives the first non-blank frame (see below). It has no say in the order in which gets them (the sdl consumer when used with melt might appear to be an exception - it isn't - it simply has a route back to the application to allow the application to interpret key presses). Tractors: To create a multitrack XML, we can use two playlists and introduce a tractor. For the purposes of demonstration, I'll add a filter here too: clip1.dv clip2.dv 0 greyscale Here we see that blank frames are inserted into the first playlist and a blank is provided at the beginning of the second - this can be visualised in the traditional timeline widget as follows: +-------+ +-------------+ |a | |a | +-------+---+-------------+ |b | +---+ Adding the filter on the top track, gives us: +-------+ +-------------+ |a | |a | +-------+---+-------------+ |greyscale | --------+---+-------------+ |b | +---+ Note that it's only applied to the visible parts of the top track. The requirement to apply a filter to the output, as opposed to a specific track leads us to the final item in the Rules section above. As an example, let's assume we wish to watermark all output, then we could use the following: clip1.dv clip2.dv 0 greyscale watermark watermark1.png Here we employ another tractor and we define a single track (being the tractor we previously defined) and apply a watermarking filter there. This is simply provided as an example - the watermarking functionality could be better handled at the playout stage itself (ie: as a filter automatically placed between all producers and the consumer). Tracks act like "layers" in an image processing program like the GIMP. The bottom-most track takes highest priority and higher layers are overlays and do not appear unless there are gaps in the lower layers or unless a transition is applied that merges the tracks on the specifed region. Practically speaking, for A/B video editing it does not mean too much, and it will work as expected; however, as a general rule apply any CGI (graphic overlays with pixbuf or titles with pango) on tracks higher than your video tracks. Also, this means that any audio-only tracks that are lower than your video tracks will play rather than the audio from the video clip. Remember, nothing is affected like mixing or compositing until one applies a transition or appropriate filter. clip1.dv clip2.mpeg 0 1 luma 0 1 mix 0.0 1.0 A "luma" transition is a video wipe processor that takes a greyscale bitmap for the wipe definition. When one does not specify a bitmap, luma performs a dissolve. The "mix" transition does an audio mix, but it interpolates between the gain scaling factors between the start and end properties - in this example, from 0.0 (none of track B) to 1.0 (all of track B). Because the bottom track starts out with a gap specified using the element, the upper track appears during the blank segment. See the demos and services.txt to get an idea of the capabilities of the included transitions. Flexibility: The information presented above is considered the MLT XML "normal" form. This is the output generated by the xml consumer, for example, when used with melt. It is the output generated when you use the "XML to File" consumer in the demo script, which beginners will find most useful for learning to use MLT XML. This section describes alternative forms the xml producer accepts. First of all, the normal form is more of a linear format with producers and playlists defined prior to their usage in a multitrack. The producer also accepts a hierarchical format with producers as children of tracks or playlist entries and with playlists as children of tracks: clip1.dv Obviously, this example is meant to demonstrate hierarchy and not effective use of playlist or multitrack! Secondly, as part of error handling, the producer is forgiving if you fail to supply , , and where one can be understood. This affords an abbreviated syntax that is less verbose and perhaps less intimidating for a human to read and understand. One can simplify the above example as: clip1.dv Yes, filters and transitions can be added to the above example after the closing multitrack tag () because it is still enclosed within the mlt body tags. If you specify in and out on a producer and it has been enclosed within an or , then the edit points apply to the playlist entry and not to the producer itself. This facilitates re-use of media: clip1.dv In the above example, the producer attribute of the entry element is a reference to the preceding producer. All references must follow the definition. The edit points supplied on the producer above will not affect the entry that references it below because the producer knows the clip is a playlist entry and optimises this situation. The advantage is that one does not need to determine every clip to be included ahead of time and specify them outside the context of the mutlitrack timeline. This form of authoring will be easier for many to visualise as a non-linear editor's timeline. Here is a more complex example: clip2.mpeg clip3.mpeg Did you notice something different in the last example? Properties can be expressed using XML attributes on the element as well. However, only non-service-specific properties are supported in this way. For example, "mlt_service" is available to any producer, filter, or transition. However, "resource" is actually service-specific. Notice the syntax of the last property, on the last transition. The producer accepts property values using the "value" attribute as well as using element text. We have seen a few different ways of expressing property values. There are a couple more for properties that can accept XML data. For example, the GDK pixbuf producer with librsvg can handle embedded SVG, and the Pango producer can handle embedded Pango markup. You can enclose the embedded XML using a CDATA section: ... ]]> Please ensure the opening CDATA tag immediately follows the opening property tag and that the section closing tag immediately precedes the closing property tag. However, the producer can also accept inline embedded XML: Currently, there is no namespace handling so a conflict will occur only on any embedded XML that contains an element named "property" because the producer collects embedded XML until it reaches a closing property tag. Entities and Parameterisation: The MLT XML producer parser supports XML entities. An example: ]> pango &msg; If you are embedding another XML document into a property value not using a CNODE section, then any DOCTYPE section must be relocated before any of the xml elements to be well-formed. See demo/svg.mlt for an example. Entities can be used to parameterise MLT XML! Using the above example, the entity declared serves as the default value for &msg;. The entity content can be overridden from the resource property supplied to the xml producer. The syntax is the familiar, url-encoded query string used with HTTP, e.g.: file?name=value&name=value... There are a couple of rules of usage. The melted LOAD command and melt command line tool require you to preface the URL with "xml:" because the query string destroys the filename extension matching peformed by the auto-loader. Also, melt looks for '=' to tokenise property settings. Therefore, one uses ':' between name and value instead of '='. Finally, since melt is run from the shell, one must enclose the URL within single quotes to prevent shell filename expansion, or similar. Needless to say, the ability to parameterise MLT XML compositions is an extremely powerful tool. An example for you to play with is available in demo/entity.mlt. Try overriding the name from melt: melt 'xml:entity.mlt?name:Charlie' Technically, the entity declaration is not needed in the head of the XML document if you always supply the parameter. However, you run the risk of unpredictable behviour without one. Therefore, it is safest and a best practice to always supply an entity declaration. It is improves the readability as one does not need to search for the entity references to see what parameters are available. Tips and Technique: If one finds the above hierarchical, abbreviated format intuitive, start with a simple template and fill and extend as needed: ...add a playlist for each track... ...add filters and transitions... By using a playlist for each track, it is easier to iteratively add new clips and blank regions as you develop the project. You will not have to use or later add when necessary. A more advanced template that allows sequencing multitracks is: ...add a playlist for each track... ...add filters and transitions... ...add a playlist for each track... ...add filters and transitions... If you end up making a collection of templates for various situations, then consider using XML Entities to make the template more effective by moving anything that should parameterised into an entity. If you want to have a silent, black background for audio and video fades, then make the top track simply . Then, use composite and volume effects. See the "Fade from/to black/silence" demo for an example (demo/mlt_fade_black). If you apply the reverse=1 property to a transition like "luma," then be careful because it also inherently swaps the roles of A and B tracks. Therefore, you need to might need to swap the a_track and b_track values if it did not turn out the way you expected. See the "Clock in and out" for an example (demo/mlt_clock_in_and_out). mlt-0.9.0/mlt++.pc.in000066400000000000000000000002271215300731300141630ustar00rootroot00000000000000 Name: mlt++ Description: C++ API for MLT multimedia framework Version: ${version} Requires: mlt-framework Libs: -L${libdir} ${libs} Cflags: ${cflags} mlt-0.9.0/mlt-config-template000066400000000000000000000015061215300731300161040ustar00rootroot00000000000000export package=framework export field=0 while [ "$1" != "" ] do case $1 in --help ) field=0 ;; --version ) field=-1 ;; --prefix ) field=-2 ;; --prefix=* ) prefix="${i#--prefix=}" ;; --cflags ) field=2 ;; --libs ) field=3 ;; --list ) field=1; package="" ;; * ) package=$1 ;; esac shift done if [ "$field" = "0" ] then echo "Usage: mlt-config [ --version ] | [ --prefix=dir ] [ [ package ] [ --cflags ] [ --libs ] ]" elif [ "$field" = "-1" ] then echo $version elif [ "$field" = "-2" ] then config=`which mlt-config` dir=`dirname $config` dir=`dirname $dir` echo $dir elif [ -f "$prefix/share/mlt/packages.dat" ] then grep "^$package" $prefix/share/mlt/packages.dat | cut -f $field else echo mlt-config cannot find package $package. fi echo >&2 "mlt-config is deprecated.

 * tractor-type service, ie:
 *
 * Producer1 \
 * Producer2 - multitrack - { filters/transitions } - tractor - consumer
 * Producer3 /
 *
 * The get_frame of a tractor pulls frames from it's connected service on all tracks and
 * will terminate as soon as it receives a test card with a last_track property. The
 * important case here is that the mulitrack does not move to the next frame until all
 * tracks have been pulled.
 *
 * Reasoning: In order to seek on a network such as above, the multitrack needs to ensure
 * that all producers are positioned on the same frame. It uses the 'last track' logic
 * to determine when to move to the next frame.
 *
 * Flaw: if a transition is configured to read from a b-track which happens to trigger
 * the last frame logic (ie: it's configured incorrectly), then things are going to go
 * out of sync.
 *
 * See playlist logic too.

The logic is complex here. A transition is typically applied to frames on the a and b tracks specified in the connect method above and only if both contain valid info for the transition type (this is either audio or image). However, the fixed a_track may not always contain data of the correct type, eg: 
	+---------+                               +-------+
	|c1       |                               |c5     | <-- A(0,1) <-- B(0,2) <-- get frame
	+---------+                     +---------+-+-----+        |          |
	                                |c4         |       <------+          |
	         +----------+-----------+-+---------+                         |
	         |c2        |c3           |                 <-----------------+
	         +----------+-------------+
During the overlap of c1 and c2, there is nothing for the A transition to do, so this results in a no operation, but B is triggered. During the overlap of c2 and c3, again, the A transition is inactive and because the B transition is pointing at track 0, it too would be inactive. This isn't an ideal situation - it's better if the B transition simply treats the frames from c3 as though they're the a track. For this to work, we cache all frames coming from all tracks between the a and b tracks.

One form is a flat set of properties on this consumer that follows the pattern: = [.=]* For example, 0=sdl 0.rescale=bilinear 1=avformat 1.target=foo.dv ... To change the profile for a particular output set the property "mlt_profile." You can put these into a MLT properties file and supply that to this consumer. Another way is to create a separate properties list for each output and set that on the consumer with a numeric name starting with zero: = ... In this format, to specify the service, use the property name "mlt_service" and, again, to specify the profile, use "mlt_profile." You can put these into a YAML Tiny file and supply that to this consumer. This is also the recommended way for applications to interact with this consumer, which is how melt and the XML producer support multiple consumers. parameters: - identifier: argument title: File type: string description: > A properties or YAML file specifying multiple consumers and their properties. required: no mlt-0.9.0/src/modules/core/consumer_null.c000066400000000000000000000112061215300731300205270ustar00rootroot00000000000000/* * consumer_null.c -- a null consumer * Copyright (C) 2003-2004 Ushodaya Enterprises Limited * Author: Charles Yates * * This library is free software; you can redistribute it and/or * modify it under the terms of the GNU Lesser General Public * License as published by the Free Software Foundation; either * version 2.1 of the License, or (at your option) any later version. * * This library is distributed in the hope that it will be useful, * but WITHOUT ANY WARRANTY; without even the implied warranty of * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

I wrote it from scratch because I found the other Open Source code to be limited by their difficulty of reuse. COMPILE: To compile this module, you must supply these options to the root configure script: --enable-gpl --enable-motion-est EXAMPLES: Estimate the motion: > melt -filter motion_est To display the motion vectors as pretty arrows: > melt -filter motion_est -filter vismv If your using a movie file that contains a crop, you will get better results with this: > melt -filter crop_detect -filter motion_est -filter vismv If your computer is unable to do the above examples in real time, try this: > melt -filter motion_est -filter vismv -consumer melt real_time=0 If you'd like to see the motion vectors without the median denoising function, do this: > melt -filter motion_est denoise=0 -filter vismv To reconstruct each frame by applying the motion to the previous frame: > melt -filter motion_est show_reconstruction=1 To compare the reconstructed frame and the real frame (while paused): > melt -filter motion_est show_reconstruction=1 toggle_when_paused=1 To show the difference (residual) between the reconstructed frame the real frame: > melt -filter motion_est show_residual=1 To automatically track an object in the frame, try this: > melt -filter autotrack_rectangle:X,Y:WxH debug=1 (Where X,Y is the origin of the rectangle indexed from upper left and WxH is the dimensions of the rectangle.) To obscure that same object in the frame, try this: > melt -filter autotrack_rectangle:X,Y:WxH obscure=1 There is now a slow motion producer that does interpolation based on the motion vectors: > melt slowmotion: _speed=0.1 method=1 debug=1 NOTES (and deficiencies): 1. Ignore shot change detection when your using the autotrack_rectangle filter. 2. Don't assume motion vectors displayed while stepping backwards and forward are that same vectors that would be calculated while playing the footage from start to finish, nonstop. Stepping forward should be fine after a few frames, however. 3. SSE instructions are lazily assumed. MMX, Altivec, and SIMD-less would be good too. 4. Motion estimation is only performed in the luma color space. 5. Motion vectors should have sub-pixel accuracy. 6. Motion vectors are not serializable yet. 7. A diligent test suite is needed. (show_reconstruction & show_residual are a start) 8. Multithreaded code will see HUGE benefits on multi-CPU systems. Donations of a multi-core cpu or a multi-cpu system to the author will encourage development. 9. Macroblock sizes are not dynamic (Though settable at runtime.) 10. Notes (5), (7), and (9) would go a long ways to making this code suitable for a modern video encoder. 11. Shot change works well but arbitrarily chosen thresholds need to be tuned. 12. Given the documentation of other motion estimation code bases, I will GLADLY clarify and document any piece of code upon request. 13. Considerable effort has been put into the speed. I usually experience 10ms or less per frame for PAL on 2.8GHZ p4.

Gunderson license: GPLv2 language: en tags: - Video description: > Deconvolution Sharpen is a filter that sharpens by way of deconvolution (i.e., trying to reverse the blur kernel, as opposed to just boosting high frequencies), more specifically by FIR Wiener filters. It is the same algorithm as used by the (now largely abandoned) Refocus plug-in for GIMP, and I suspect the same as in Photoshop's “Smart Sharpen†filter. The effect gives generally better results than unsharp masking, but can be very GPU intensive, and requires a fair bit of tweaking to get good results without ringing and/or excessive noise. parameters: - identifier: matrix_size title: Matrix Size type: integer minimum: 0 maximum: 10 default: 5 mutable: yes - identifier: circle_radius title: Circle Radius type: float minimum: 0 default: 2 mutable: yes - identifier: gaussian_radius title: Gaussian Radius type: float minimum: 0 default: 0 mutable: yes - identifier: correlation title: Correlation type: float minimum: 0 default: 0.95 mutable: yes - identifier: noise title: Noise Level type: float minimum: 0 default: 0.01 mutable: yes mlt-0.9.0/src/modules/opengl/filter_glsl_manager.cpp000066400000000000000000000235541215300731300225470ustar00rootroot00000000000000/* * filter_glsl_manager.cpp * Copyright (C) 2011-2012 Christophe Thommeret * Copyright (C) 2013 Dan Dennedy * * This program is free software; you can redistribute it and/or modify * it under the terms of the GNU General Public License as published by * the Free Software Foundation; either version 2 of the License, or * (at your option) any later version. * * This program is distributed in the hope that it will be useful, * but WITHOUT ANY WARRANTY; without even the implied warranty of * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

Mathematically speaking, it is a bit unusual to look at gamma as a color, but it works pretty well in practice. The classic formula is: output = (gain * (x + lift * (1-x)))^(1/gamma). The lift is actually a case where we actually would _not_ want linear light; since black by definition becomes equal to the lift color, we want lift to be pretty close to black, but in linear light that means lift affects the rest of the curve relatively little. Thus, we actually convert to gamma 2.2 before lift, and then back again afterwards.
