It is released under the terms of the GPL license. The A/52 standard is used in a variety of applications, including digital television and DVD. It is also known as AC-3. The main goals in liba52 development are: * Portability - Currently all of the code is written in C, and when we write platform-specific optimizations we will always keep a generic C routine to fall back on. * Reuseability - we do not want liba52 to include any project-specific code, but it should still include enough features to be used by very diverse projects. * Precision - We are trying to implement all of the A/52 standard, and to have a very precise output by doing all the calculations in floating point. We have a test suite that detects any deviation in the output when compared to previous versions. We do not have access to official A/52 test vectors though, so we have to use our judgement to ensure that such deviations are only intruduced when we fix bugs ! * Speed - liba52 is really fast, on any modern PC it should take only a few percent of CPU time. The project homepage is at http://liba52.sourceforge.net/ A52DEC a52dec is a test program for liba52. It decodes ATSC A/52 streams, and also includes a demultiplexer for mpeg-1 and mpeg-2 program streams. The liba52 source code is always distributed in the a52dec package, to make sure it easier for people to test it. The basic usage is to just type "a52dec file" where file is an ATSC A/52 file. The "-s" option must be used for multiplexed (audio and video) mpeg-2 files. These files are usualy found on the internet or on unencrypted DVDs. The "-o" option is used to select a given output layer. By default a52dec does a stereo downmix and outputs to your speakers, but you can try other choices using this option. This is also used for performance testing and conformance testing. The "-c" option is used to disable all optimizations (currently only djbfft). The "-r" option is used to disable the dynamic range compression. OTHER PROJECTS USING LIBA52 liba52 (and its ancestor libac3) is being used by various other projects, including: * xine (http://xine.sourceforge.net/) - started as a simple mpeg-2 audio and video decoder, but it since became a full-featured DVD and video media player. * MPlayer (http://www.MPlayerHQ.hu) - another good player, it is also very robust against damaged streams. * movietime (http://movietime.sourceforge.net/) - still quite young, but it looks very promising ! * ffmpeg (http://ffmpeg.sourceforge.net/) - a nice audio/video encoder and transcoder, uses liba52 for decoding A/52 streams. * Ogle (http://www.dtek.chalmers.se/groups/dvd/) - a good DVD player with menu support * a52decX (http://homepage1.nifty.com/~toku/software_en.html) - a graphical interface for a52dec in macintosh osX. * bd4go (http://denisx.dyndns.org/bd4go/) - another graphical interface for macintosh osX. * OMS (http://www.linuxvideo.org/oms/) * XMPS (http://xmps.sourceforge.net/) * GStreamer (http://www.gstreamer.net/) - a framework for streaming media; it has an A/52 decoding plugin based on liba52. * mpeglib (http://mpeglib.sourceforge.net/) - a video decoding library that usess liba52 when decoding A/52 streams. If you use liba52 in another project, let us know ! VideoLAN (http://www.videolan.org/) does not use liba52, but this is still a cool project :) TASKS There are several places where we could easily use some help: * Web design: This site sucks ! at the very least, we'd like to come up with a nicer background picture and a logo. * Testing: If you find any stream that does not decode right with liba52, let us know ! The best thing would be to mail to the liba52-devel mailing list. Also if you have access to encoders, we'd love to get test streams that would be free of rights - so that we can put them on this server. * Coding: you can have a look in the TODO file first ! The most important item is probably to make the code fully reentrant. * Porting: If you're porting to a new architecture, you might want to experiment with the compile flags defined in configure.in . When you figure out whats fastest on your platform, send us a patch ! REFERENCES The A/52 standard, as published by the ATSC, is available at http://www.atsc.org/standards/a_52a.pdf CVS SNAPSHOTS A daily snapshot is created using "make distcheck" every night and uploaded to http://liba52.sourceforge.net/files/a52dec-snapshot.tar.gz . It is easier to use than the CVS repository, because you do not need to have the right versions of automake, autoconf and libtool installed. It might be convenient when working on a liba52 port for example. CVS REPOSITORY The latest liba52 and a52dec source code can always be found by anonymous CVS: # export CVSROOT=:pserver:anonymous@cvs.liba52.sourceforge.net:/cvsroot/liba52 # cvs login (Just press Return when prompted for a password) # cvs checkout a52dec You can also browse the latest changes online at http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/liba52/a52dec/ The other CVS modules are ac3dec-livid for the CVS history of the project while it was still hosted on the linuxvideo.org servers, and ac3dec for the CVS history of the project while the linuxvideo.org servers were down and before the library switched its name to liba52. MAILING LISTS See the subscription information at http://liba52.sourceforge.net/lists.html liba52-devel This is the main mailing list for technical discussion about liba52. Anyone wanting to work on liba52, or maybe just stay informed about the development process, should probably subscribe to this list. liba52-checkins All liba52 checkins are announced there. This is a good way to keep track of what goes into CVS. liba52-announce This is a very low traffic mailing list, only for announcements of new versions of liba52. Only project administrators can post there. a52dec-0.7.4/AUTHORS0000644000175000017500000000200707520647445007332 Aaron Holtzman started the project and made the initial working implementation.

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.

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.

The entire frame is checksummed before playback. ac3dec-0.5.6 Tue Nov 16 00:37:34 EST 1999 -Irix support -Alpha fixes -Minor performance enhancements to downmix and imdct -OpenBSD fixes -extract_ac3 can now read from stdin -Change output_linux to block on write instead of using the ring buffer. Let me know if this causes/fixes any problems ac3dec-0.5.5 Wed Aug 25 15:36:44 EDT 1999 -Fixed a cut and paste bug (argh!) in parse.c which potentially screwed up delta bit allocation info. -Martin Mueller informed me that I was missing some corrections from the AC-3 errata document. It turns out that I used an earlier version of the errata when I initially wrote ac3dec. Fortunately the errata fix the outstanding bugs that I was pulling my hair out on for a long time. Woohoo! Thanks Martin. Kudos to Dolby Labs for keeping their documentation up to date as well. -stereo downmixing (downmix.c) is now in. Matrix encoded surround (Dolby Prologic Surround) should work too. -clipping due to high level signals has been fixed. We normalize a block of samples by its maximum absolute value if the max exceeds the %100 digital level. This shouldn't be a problem, but for some reason some channels have a dynamic range that exceeds [-1.0,1.0]. I blame the encoder :) -Multiple track support in extract_ac3. Simply just give it the track number you want [1,8] after the filename. ac3dec-0.5.4 Thu Jul 29 16:55:10 PDT 1999 -Fixed a stupid bug with the coupling channel that was causing high frequencies to be attenuated. -Re-wrote the extract_ac3 tool. -Added to a tool to verify the checksums on a given AC3 stream. (tools/verify_ac3) ac3dec-0.5.3 Mon Jul 12 10:45:56 PDT 1999 -Fixed problems related to streams with coupling channel enabled. -Minor performance enhancements ac3dec-0.5.2 Sun Jul 4 12:00:25 PDT 1999 -output_linux.c patch provided by Michael Holzt ac3dec-0.5.1 Wed Jun 30 17:48:52 PDT 1999 -Compiles and dies gracefully under Linux now. ac3dec-0.5.0 Wed Jun 23 11:06:06 EDT 1999 -First public release of ac3dec. a52dec-0.7.4/INSTALL0000644000175000017500000000345707462446310007316 Unix build instructions ----------------------- ./configure make make install If you install from CVS you'll have to run ./bootstrap first Building for win32 ------------------ There are at least three ways to do it: - natively on Windows using Microsoft VC++ and the vc++ project included in this distribution. - natively on Windows using MSYS + MINGW (www.mingw.org) (MSYS is a minimal build environnement to compile unixish projects under windows. It provides all the common unix tools like sh, gmake...) - or on Linux, using the mingw32 cross-compiler Building using MSYS + MINGW on windows -------------------------------------- First you will need to download and install the latest MSYS (version 1.0.7 as of now) and MINGW. The installation is really easy. Begin with the MSYS auto-installer and once this is done, extract MINGW into c:\msys\1.0\mingw. You also have to remember to remove the make utility included with MINGW as it conflicts with the one from MSYS (just rename or remove c:\msys\1.0\mingw\bin\make.exe). http://prdownloads.sourceforge.net/mingw/MSYS-1.0.7-i686-2002.04.24-1.exe http://prdownloads.sourceforge.net/mingw/MinGW-1.1.tar.gz Then you can build the package using: # ./configure # make Building using the mingw32 cross-compiler ----------------------------------------- You need to install mingw32 first. For Debian GNU/Linux users, there is a mingw32 package. Otherwise you might get it from the mingw site at http://www.mingw.org/download.shtml. The videolan project also keeps precompiled mingw32 binaries at http://www.videolan.org/vlc/windows.html . If you install these, you'll have to set your PATH accordingly to include /usr/local/cross-tools/bin too. The build should then proceed using something like: # CC=i586-mingw32msvc-gcc ./configure --host=i586-mingw32msvc # make a52dec-0.7.4/Makefile.am0000644000175000017500000000013307407226401010301 SUBDIRS = autotools include doc liba52 libao src vc++ test EXTRA_DIST = HISTORY bootstrap a52dec-0.7.4/NEWS0000644000175000017500000000244007520664774006766 a52dec-0.7.4 Sat Jul 27 20:44:00 PDT 2002 The library is now fully reentrant. Added win32 output module, al file output, gain control. A few additional portability enhancements. a52dec-0.7.3 Wed Feb 20 23:38:22 PST 2002 Performance enhancements, from 40% to 80% depending on streams. Fixed a few embarassing bugs in liba52: one memory corruption issue and a few minor portability problems. Several new output modules, and fixes in the existing .wav file output. a52dec-0.7.2 Sun Dec 16 14:39:56 PST 2001 Minor bugfixes, performance and portability enhancements. Also added wav format output, and reduced the demux buffer size which makes it easier to use a52dec as a pipe. a52dec-0.7.1 Thu Aug 30 02:13:23 PDT 2001 Minor release for bugfixes. Looks like 0.7.0 was a bit rushed out. Now compiles with gcc 3.0, made sure mlib implementation works, and fixed a small bug in the a52dec test program. a52dec-0.7.0 Thu Aug 23 23:18:00 PDT 2001 First release since more than one year ! The most user-noticeable additions are the downmix to arbitrary speaker configurations, and the implementation of dynamic range compression. The speed has been improved by a factor of 2 to 3, the conformance and precision should be higher, and we also fixed a small bug when playing stereo rematrixed streams. a52dec-0.7.4/TODO0000644000175000017500000000067307456476371006767 * implement A/52a downmix extensions * use restrict pointers where appropriate * reduce size of delay buffer by 50% * get rid of globals in bitstream parsing * get rid of statics in imdct.c * avoid overflows, including reading the a52 stream !!! * make dither code faster (generate dither table in advance ?) * redo all bit allocation if previous frame had zero_snr_offsets * make dynrng work in dual-channel streams * update bitstream code a52dec-0.7.4/acinclude.m40000644000175000017500000000705607476315451010463 dnl AC_C_RESTRICT dnl Do nothing if the compiler accepts the restrict keyword. dnl Otherwise define restrict to __restrict__ or __restrict if one of dnl those work, otherwise define restrict to be empty.

A52_3F : 3 front channels (left, center, right) A52_2F1R : 2 front, 1 rear surround channel (L, R, S) A52_3F1R : 3 front, 1 rear surround channel (L, C, R, S) A52_2F2R : 2 front, 2 rear surround channels (L, R, LS, RS) A52_3F2R : 3 front, 2 rear surround channels (L, C, R, LS, RS) A52_LFE : Low frequency effects channel. Normally used to connect a subwoofer. Can be combined with any of the above channels. For example: A52_3F2R | A52_LFE -> 3 front, 2 rear, 1 LFE (5.1) Initialization -------------- sample_t * a52_init (uint32_t mm_accel); Initializes the A/52 library. Takes as a parameter the acceptable optimizations which may be used, such as MMX. These are found in the included header file 'mm_accel', along with an autodetection function (mm_accel()). Currently, the only accelleration implemented is MM_ACCEL_MLIB, which uses the 'mlib' library if installed. mlib is only available on some Sun Microsystems platforms. The return value is a pointer to a properly-aligned sample buffer used for output samples. Probing the bitstream --------------------- int a52_syncinfo (uint8_t * buf, int * flags, int * sample_rate, int * bit_rate); The A/52 bitstream is composed of several a52 frames concatenated one after each other. An a52 frame is the smallest independantly decodable unit in the stream. buf must contain at least 7 bytes from the input stream. If these look like the start of a valid a52 frame, a52_syncinfo() returns the size of the coded frame in bytes, and fills flags, sample_rate and bit_rate with the information encoded in the stream. The returned size is guaranteed to be an even number between 128 and 3840. sample_rate will be the sampling frequency in Hz, bit_rate is for the compressed stream and is in bits per second, and flags is a description of the coded channels: the A52_LFE bit is set if there is an LFE channel coded in this stream, and by masking flags with A52_CHANNEL_MASK you will get a value that describes the full-bandwidth channels, as one of the A52_CHANNEL...A52_3F2R flags. If this can not possibly be a valid frame, then the function returns 0. You should then try to re-synchronize with the a52 stream - one way to try this would be to advance buf by one byte until its contents looks like a valid frame, but there might be better application-specific ways to synchronize. It is recommended to call this function for each frame, for several reasons: this function detects errors that the other functions will not double-check, consecutive frames might have different lengths, and it helps you re-sync with the stream if you get de-synchronized. Starting to decode a frame -------------------------- int a52_frame (a52_state_t * state, uint8_t * buf, int * flags, sample_t * level, sample_t bias); This starts the work of decoding the A/52 frame (to be completed using a52_block()). buf should point to the beginning of the complete frame of the full size returned by a52_syncinfo(). You should pass in the flags the speaker configuration that you support, and liba52 will return the speaker configuration it will use for its output, based on what is coded in the stream and what you asked for. For example, if the stream contains 2+2 channels (a52_syncinfo() returned A52_2F2R in the flags), and you have 3+1 speakers (you passed A52_3F1R), then liba52 will choose do downmix to 2+1 speakers, since there is no center channel to send to your center speaker. So in that case the left and right channels will be essentially unmodified by the downmix, and the two surround channels will be added together and sent to your surround speaker. liba52 will return A52_2F1R to indicate this. The good news is that when you downmix to stereo you dont have to worry about this, you will ALWAYS get a stereo output no matter what was coded in the stream. For more complex output configurations you will have to handle the case where liba52 couldnt give you what you wanted because some of the channels were not encoded in the stream though. Level, bias, and A52_ADJUST_LEVEL: Before downmixing, samples are floating point values with a range of [-1,1]. Most types of downmixing will combine channels together, which will potentially result in a larger range for the output samples. liba52 provides two methods of controlling the range of the output, either before or after the downmix stage. If you do not set A52_ADJUST_LEVEL, liba52 will multiply the samples by your level value, so that they fit in the [-level,level] range. Then it will apply the standardized downmix equations, potentially making the samples go out of that interval again. The level parameter is not modified. Setting the A52_ADJUST_LEVEL flag will instruct liba52 to treat your level value as the intended range interval after downmixing. It will then figure out what level to use before the downmix (what you should have passed if you hadnt used the A52_ADJUST_LEVEL flag), and overwrite the level value you gave it with that new level value. The bias represents a value which should be added to the result regardless: output_sample = (input_sample * level) + bias; For example, a bias of 384 and a level of 1 tells liba52 you want samples between 383 and 385 instead of -1 and 1. This is what the sample program a52dec does, as it makes it faster to convert the samples to integer format, using a trick based on the IEEE floating-point format. This function also initialises the state for that frame, which will be reused next when decoding blocks. Dynamic range compression ------------------------- void a52_dynrng (a52_state_t * state, sample_t (* call) (sample_t, void *), void * data); This function is purely optional. If you dont call it, liba52 will provide the default behaviour, which is to apply the full dynamic range compression as specified in the A/52 stream. This basically makes the loud sounds softer, and the soft sounds louder, so you can more easily listen to the stream in a noisy environment without disturbing anyone. If you do call this function and set a NULL callback, this will totally disable the dynamic range compression and provide a playback more adapted to a movie theater or a listening room. If you call this function and specify a callback function, this callback might be called up to once for each block, with two arguments: the compression factor 'c' recommended by the bitstream, and the private data pointer you specified in a52_dynrng(). The callback will then return the amount of compression to actually use - typically pow(c,x) where x is somewhere between 0 and 1. More elaborate compression functions might want to use a different value for 'x' depending wether c>1 or c<1 - or even something more complex if this is what you want. Decoding blocks --------------- int a52_block (a52_state_t * state, sample_t * samples); Every A/52 frame is composed of 6 blocks, each with an output of 256 samples for each channel. The a52_block() function decodes the next block in the frame, and should be called 6 times to decode all of the audio in the frame. After each call, you should extract the audio data from the sample buffer. The sample pointer given should be the one a52_init() returned. After this function returns, the samples buuffer will contain 256 samples for the first channel, followed by 256 samples for the second channel, etc... the channel order is LFE, left, center, right, left surround, right surround. If one of the channels is not present in the liba52 output, as indicated by the flags returned by a52_frame(), then this channel is skipped and the following channels are shifted so liba52 does not leave an empty space between channels. Pseudocode example ------------------ sample_t * samples = a52_init (mm_accel()); loop on input bytes: if at least 7 bytes in the buffer: bytes_to_get = a52_syncinfo (...) if bytes_to_get == 0: goto loop to keep looking for sync point else get rest of bytes a52_frame (state, buf, ...) [a52_dynrng (state, ...); this is only optional] for i = 1 ... 6: a52_block (state, samples) convert samples to integer and queue to soundcard a52dec-0.7.4/liba52/0000777000175000017500000000000007520665037007422 5a52dec-0.7.4/liba52/Makefile.in0000644000175000017500000002133107520665037011403 # Makefile.in generated automatically by automake 1.4-p5 from Makefile.am # Copyright (C) 1994, 1995-8, 1999, 2001 Free Software Foundation, Inc. # This Makefile.in is free software; the Free Software Foundation # gives unlimited permission to copy and/or distribute it, # with or without modifications, as long as this notice is preserved. # This program is distributed in the hope that it will be useful, # but WITHOUT ANY WARRANTY, to the extent permitted by law; without # even the implied warranty of MERCHANTABILITY or FITNESS FOR A # PARTICULAR PURPOSE.

This mode of operation is selected by either setting the environment variable POSIXLY_CORRECT, or using `+' as the first character of the list of option characters. PERMUTE is the default. We permute the contents of ARGV as we scan, so that eventually all the non-options are at the end. This allows options to be given in any order, even with programs that were not written to expect this. RETURN_IN_ORDER is an option available to programs that were written to expect options and other ARGV-elements in any order and that care about the ordering of the two. We describe each non-option ARGV-element as if it were the argument of an option with character code 1. Using `-' as the first character of the list of option characters selects this mode of operation. The special argument `--' forces an end of option-scanning regardless of the value of `ordering'.

If an element of ARGV starts with '-', and is not exactly "-" or "--", then it is an option element. The characters of this element (aside from the initial '-') are option characters. If `getopt' is called repeatedly, it returns successively each of the option characters from each of the option elements. If `getopt' finds another option character, it returns that character, updating `optind' and `nextchar' so that the next call to `getopt' can resume the scan with the following option character or ARGV-element. If there are no more option characters, `getopt' returns -1. Then `optind' is the index in ARGV of the first ARGV-element that is not an option. (The ARGV-elements have been permuted so that those that are not options now come last.) OPTSTRING is a string containing the legitimate option characters. If an option character is seen that is not listed in OPTSTRING, return '?' after printing an error message. If you set `opterr' to zero, the error message is suppressed but we still return '?'. If a char in OPTSTRING is followed by a colon, that means it wants an arg, so the following text in the same ARGV-element, or the text of the following ARGV-element, is returned in `optarg'. Two colons mean an option that wants an optional arg; if there is text in the current ARGV-element, it is returned in `optarg', otherwise `optarg' is set to zero. If OPTSTRING starts with `-' or `+', it requests different methods of handling the non-option ARGV-elements. See the comments about RETURN_IN_ORDER and REQUIRE_ORDER, above. Long-named options begin with `--' instead of `-'. Their names may be abbreviated as long as the abbreviation is unique or is an exact match for some defined option. If they have an argument, it follows the option name in the same ARGV-element, separated from the option name by a `=', or else the in next ARGV-element. When `getopt' finds a long-named option, it returns 0 if that option's `flag' field is nonzero, the value of the option's `val' field if the `flag' field is zero. The elements of ARGV aren't really const, because we permute them. But we pretend they're const in the prototype to be compatible with other systems. LONGOPTS is a vector of `struct option' terminated by an element containing a name which is zero. LONGIND returns the index in LONGOPT of the long-named option found. It is only valid when a long-named option has been found by the most recent call. If LONG_ONLY is nonzero, '-' as well as '--' can introduce long-named options. */ int _getopt_internal (argc, argv, optstring, longopts, longind, long_only) int argc; char *const *argv; const char *optstring; const struct option *longopts; int *longind; int long_only; { int print_errors = opterr; if (optstring[0] == ':') print_errors = 0; optarg = NULL; if (optind == 0 || !__getopt_initialized) { if (optind == 0) optind = 1; /* Don't scan ARGV[0], the program name. */ optstring = _getopt_initialize (argc, argv, optstring); __getopt_initialized = 1; } /* Test whether ARGV[optind] points to a non-option argument.
