Please try to follow these for any new contributions: * Code should not be wider than 79 columns. * A tab character should be displayed as 8 columns wide. * Indentations are 4 columns wide. * Braces are never alone on a line, instead they are on the same line as their associated control flow (if/then/else/while/for) statement. Functions are a special case, their opening and ending braces are alone on their own line, in the leftmost column. This is all standard K&R coding style. * Braces are optional. It's ok to skip them if there is only one statement in the block you'd put the braces around. * There is always a space separating the function name and the associated argument list i.e. f () * There is always a space separating an if/while/for control flow statement and the associated conditions i.e. if (x) * Function argument lists are of the form f (a, b, c) i.e. there is always a space between the arguments. * Pointers are declared with spaces both before and after the star. * There are no parenthesis around a return expression i.e. return x; * Non-static functions have names of the form mpeg2_* Here is a short example for reference: static int foo (int bar, int baz, int * quux) { if (bar == baz) return *quux; else do { bar += *quux; quux++; } while (bar != baz); return *quux + bar; } * For xemacs users, this is what I use: (defconst mpeg2-c-style '("gnu" (c-basic-offset . 4) (c-label-minimum-indentation . 0) (c-offsets-alist . ( (knr-argdecl-intro . +) (topmost-intro-cont . +) )) )) (c-add-style "mpeg2" mpeg2-c-style) Then to use that coding style, type M-x c-set-style mpeg2 * For emacs users, the following should work: (defun mpeg2-c-mode () "C mode with adjusted defaults for use with mpeg2dec." (interactive) (c-mode) (c-set-style "gnu") (setq c-basic-offset 4)) Then to use that coding style, type M-x mpeg2-c-mode * For vim users, the following might help: set noexpandtab set tabstop=8 set shiftwidth=4 libmpeg2-0.5.1/INSTALL0000644000175000017500000000346611035207165011201 00000000000000Unix build instructions ----------------------- ./configure make make install If you install from Subversion 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 libmpeg2-0.5.1/NEWS0000644000175000017500000001470011040124254010631 00000000000000libmpeg2-0.5.1 Fri Jul 18 16:28:49 CEST 2008 This bugfix release fixes issues with the installation of headers and pkgconfig files. libmpeg2-0.5.0 Fri Jun 11 23:42:12 CET 2008 This release brings libmpeg2 up to date with recent contributions, compilers and systems. New optimizations have been provided for SSE2 and ARM instruction sets, while a lot of warnings triggered by recent compiler changes have been fixed. A new function has been added to guess the aspect ratio of streams where it is not properly coded. Also it is now possible to retrieve the value of the MPEG-2 repeat_first_field flag, and to be notified when the sequence header of a stream changes (eg. aspect ratio on-the-fly changes). mpeg2dec-0.4.1 Wed Feb 15 17:08:28 CET 2006 This is a bugfix release. It is completely API and ABI compatible with version 0.4.0. The build system now supports newer versions of the autotools and can find them in weird places on FreeBSD and OS X systems. We also support x86 accelerations on the AMD64 CPU, including on FreeBSD. The AltiVec features are now better detected. Peter Gubanov found a bug in the 4:4:4 chroma handling, Nicolas Joly found a memory leak in the Xshm code on remote displays and Roberto Huelga found alignment issues in the sample3 and sample5 examples. Gildas Bazin contributed a patch for more tolerance for invalid sequence display extensions. There are also two new maintainers to help Michel in his task: Sam Hocevar and Christophe Massiot, from the VideoLAN project. mpeg2dec-0.4.0 Tue Dec 23 03:04:35 PST 2003 Jeez, it's been way too long since the last release. The big functionality that warrants a 0.4.x version number is that we added support for 4:2:2 for 4:4:4 chroma formats. Thanks to Peter Gubanov for starting the effort there. A large part of the development effort has been to fix corner cases that happen with bad or corrupted streams, concatenated streams, etc... Regis Duchesne created test cases for this, which was a huge help. Right now the situation is that we don't know how to make libmpeg2 crash even when we try hard. There is a new helper library for color conversion to common format (currently rgb and uyvy). The ABI between libmpeg2 and libmpeg2convert might change in the future, but source code compatibility will be preserved. In the past people were supposed to write their own color conversion routines which was a pain since the API was messy. David S. Miller contributed some very nice sparc VIS optimizations for the motion compensation. There are no VIS optimizations for the IDCT yet but the plan is to get these in for a future 0.4.1 release. New functions have been added to set the buffer stride and to reset the decoder (typically after seeking thru a file). There is some very basic documentation in doc/* - it's still quite limited though. My good resolution for 2004 is to write better documentation :) In the mean time feel free to ask on mpeg2dec-devel or on irc.freenode.net channel #livid The speed has not changed much since last release - we tend to be about 1% faster. That's not too bad considering we have new features. mpeg2dec-0.3.1 Fri Dec 13 22:15:36 PST 2002 This is mainly a maintainance release. On the API side, libmpeg2 now includes some CPU detection code - so it will by default automatically use whatever features are available on the CPU it runs on. There is a function to override this, mainly for testing purposes. There has been a few speed improvements too - there is now some alpha specific code that makes the library more than twice faster on these machines, and the C IDCT has also been improved which translates to about 6% speed improvement for people who use this code. Finally, a few bugs have been fixed, most notably some memory leaks and sparc/HPPA/IA64 build issues. mpeg2dec-0.3.0 Wed Nov 27 23:23:23 PST 2002 The main goal of this release is to preview the new libmpeg2 API. The old API was not flexible enough for most users, as a result various projects (xine, mplayer etc...) ended up rewriting their own versions of decode.c. The goal with this new API is that it will be flexible enough for people to actually use it instead of rolling their own :) In many respects, this code is less mature than the 0.2.x codebase was. There will probably be a few changes in future versions regarding color conversion and CPU detection, to cite a few. The goal is to get a release out and then add the missing features in future 0.3.x releases. In addition to the new API, there are a few new features already too. For example, we now have improved the error handling, which should help applications who do seeking for example. Also a few minor speed improvements (about 7%) and SIMD optimizations now enabled in the VC++ port too. mpeg2dec-0.2.1 Sun Mar 17 23:24:04 PST 2002 Two major new features: First, a much higher tolerance to corrupted streams. Instead of just segfaulting, we should now be able to keep going after errors. There is no test suite for this feature yet though. Second, the altivec optimizations provide a huge speedup (more than 2.5x) on ppc g4 machines. High definition video streams are now supported. There is also native support for compiling using VC++. And, the libvo interface has been slightly extended so people can more easily make use of the various mpeg flags. mpeg2dec-0.2.0 Thu Feb 15 20:12:34 PST 2001 The most important new feature is the support for field pictures. mpeg2dec is now able to display any conformant "main profile @ main level" mpeg-2 stream. This means any stream you should actually encounter in practice :) We also added some more accelerations for motion compensation and color conversion - 3Dnow and SSE. Non-x86 accelerations would be welcome - patches anyone ? libmpeg2 and libvo are now fully reentrant. This will enable other projects to reuse the mpeg2dec codebase without patches. For the same reason we added support for "make install" Libvo has been switched to a new API. The immediate advantage is that it allowed us to get rid of the "HACK_MODE" setting - you really dont want to know. In the future this will also help a lot with the implementation of synchro. Portability enhancements - including support for win32 DLLs. This was done to get into the hearts of a few more developpers :) mpeg2dec-0.1.7 Thu Nov 2 21:38:33 PST 2000 First release since march ! Lots of new features : improved performance, mpeg-1 and mpeg-2 support, integrated demuxer, standards compliance. The major missing feature is mpeg-2 field pictures, this is planned for mpeg2dec-0.2.0 libmpeg2-0.5.1/.auto/0000777000175000017500000000000011040127537011251 500000000000000libmpeg2-0.5.1/.auto/depcomp0000755000175000017500000004271311040125664012550 00000000000000#! /bin/sh # depcomp - compile a program generating dependencies as side-effects scriptversion=2007-03-29.01 # Copyright (C) 1999, 2000, 2003, 2004, 2005, 2006, 2007 Free Software # Foundation, Inc. # 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, 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.

The OPTS string is a list of characters which are recognized option letters, optionally followed by colons, specifying that that letter takes an argument, to be placed in `optarg'. If a letter in OPTS is followed by two colons, its argument is optional. This behavior is specific to the GNU `getopt'. The argument `--' causes premature termination of argument scanning, explicitly telling `getopt' that there are no more options.

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.

In other enviroments dnl we can use the inet-types in which would define the dnl typedefs int8_t and u_int8_t respectivly. dnl dnl This macros will create a local "_stdint.h" or the headerfile given as dnl an argument. In many cases that file will just "#include " dnl or "#include ", while in other environments it will provide dnl the set of basic 'stdint's definitions/typedefs: dnl int8_t,uint8_t,int16_t,uint16_t,int32_t,uint32_t,intptr_t,uintptr_t dnl int_least32_t.. int_fast32_t.. intmax_t dnl which may or may not rely on the definitions of other files, dnl or using the AC_CHECK_SIZEOF macro to determine the actual dnl sizeof each type. dnl dnl if your header files require the stdint-types you will want to create an dnl installable file mylib-int.h that all your other installable header dnl may include. So if you have a library package named "mylib", just use dnl AX_CREATE_STDINT_H(mylib-int.h) dnl in configure.ac and go to install that very header file in Makefile.am dnl along with the other headers (mylib.h) - and the mylib-specific headers dnl can simply use "#include " to obtain the stdint-types. dnl dnl Remember, if the system already had a valid , the generated dnl file will include it directly.

It is released under the terms of the GPL license. The main goals in libmpeg2 development are: * Conformance - libmpeg2 is able to decode all mpeg streams that conform to certain restrictions: "constrained parameters" for mpeg-1, and "main profile" for mpeg-2. In practice, this is what most people are using. For streams that follow these restrictions, we believe libmpeg2 is 100% conformant to the mpeg standards - and we have a pretty extensive test suite to check this. * Speed - there has been huge efforts there, and we believe libmpeg2 is the fastest library around for what it does. Please tell us if you find a faster one ! With typical video streams as found on DVD's, and doing only decoding with no display, you should be able to get about 110 fps on a PIII/666, or 150 fps on an Athlon/950. This is less than 20 cycles per output pixel. In a real player program, the display routines will probably take as much time as the actual decoding ! * Portability - most of the code is written in C, and when we use platform-specific optimizations (typically assembly routines, currently used for the motion compensation and the inverse cosine transform stages) we always have a generic C routine to fall back on. This should be portable to all architectures - at least we have heard reports from people running this code on x86, ppc, sparc, arm and sh4. Assembly-optimized implementations are available on x86 (MMX) and ppc (altivec) architectures. Ultrasparc (VIS) is probably the next on the list - we'll see. * Reuseability - we do not want libmpeg2 to include any project-specific code, but it should still include enough features to be used by very diverse projects. We are only starting to get there - the best way to help here is to give us some feedback ! The project homepage is at http://libmpeg2.sourceforge.net/ MPEG2DEC mpeg2dec is a test program for libmpeg2. It decodes mpeg-1 and mpeg-2 video streams, and also includes a demultiplexer for mpeg-1 and mpeg-2 program streams. It is purposely kept simple : it does not include features like reading files from a DVD, CSS, fullscreen output, navigation, etc... The main purpose of mpeg2dec is to have a simple test bed for libmpeg2. The libmpeg2 source code is always distributed in the mpeg2dec package, to make it easier for people to test it. The basic usage is to just type "mpeg2dec file" where file is a demultiplexed mpeg video file. The "-s" option must be used for multiplexed (audio and video) mpeg files using the "program stream" format. These files are usualy found on the internet or on unencrypted DVDs. The "-t" option must be used for multiplexed (audio and video) mpeg files using the "transport stream" format. These files are usualy found in digital TV applications. The "-o" option is used to select a given output module - for example to redirect the output to a file. This is also used for performance testing and conformance testing. The "-c" option is used to disable all optimizations. OTHER PROJECTS USING LIBMPEG2 libmpeg2 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. * VideoLAN (http://www.videolan.org/) - video streaming over an ethernet network, can also be used as a standalone 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 ! * mpeg2decX (http://homepage1.nifty.com/~toku/software_en.html) - a graphical interface for mpeg2dec for macintosh osX. * TCVP (http://tcvp.sf.net) - video and music player for unix. * drip (http://drip.sourceforge.net/) - a DVD to DIVX transcoder. * PoMP (http://www.dmclab.hanyang.ac.kr/research/project/PoDS/PoDS_sw.htm) - a research player optimized to minimize disk power consumption. * OMS (http://www.linuxvideo.org/oms/) * XMPS (http://xmps.sourceforge.net/) * GStreamer (http://www.gstreamer.net/) - a framework for streaming media; it has an mpeg2 decoding plugin based on libmpeg2. * mpeglib (http://mpeglib.sourceforge.net/) - a video decoding library that usess libmpeg2 when decoding mpeg streams. * daphne (http://daphne.rulecity.com/) - a laserdisc arcade game simulator. * GOPchop (http://outflux.net/unix/software/GOPchop/) - a GOP-accurate editor for MPEG2 streams. If you use libmpeg2 in another project, let us know ! TASKS There are several places where we could easily use some help: * Documentation: libmpeg2 still has no documentation. Every project using it has had to figure things out by looking at the header files, at the mpeg2dec sample application, and by asking questions. Writing down a nice documentation would make the code more easily reuseable. * Testing: If you find any stream that does not decode right with libmpeg2, let us know ! The best thing would be to mail to the libmpeg2-devel mailing list. Also, it would be nice to build a stress test so we can make sure libmpeg2 never crashes on bad streams. * Coding: There is a small TODO list in the mpeg2dec package, you can have a look there ! Most items are pretty terse though. * 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 ! * Assembly optimizations: We only have x86 and altivec optimizations yet, it would be worthwhile writing routines for other architectures, especially those that have SIMD instruction set extensions ! Also the yuv2rgb x86 routines could probably be optimized a lot. SUBVERSION REPOSITORY The latest libmpeg2 and mpeg2dec source code can always be found by anonymous Subversion: $ svn checkout svn://svn.videolan.org/libmpeg2/trunk libmpeg2 You can also browse the latest changes online at https://trac.videolan.org/libmpeg2/browser MAILING LISTS See the subscription information at http://libmpeg2.sourceforge.net/lists.html libmpeg2-devel This is the main mailing list for technical discussion about libmpeg2. Anyone wanting to work on libmpeg2, or maybe just stay informed about the development process, should probably subscribe to this list. libmpeg2-checkins All libmpeg2 checkins are announced there. This is a good way to keep track of what goes into CVS. libmpeg2-announce This is a very low traffic mailing list, only for announcements of new versions of libmpeg2. Only project administrators can post there. libmpeg2-0.5.1/aclocal.m40000644000175000017500000102351711040125660012003 00000000000000# generated automatically by aclocal 1.10.1 -*- Autoconf -*- # Copyright (C) 1996, 1997, 1998, 1999, 2000, 2001, 2002, 2003, 2004, # 2005, 2006, 2007, 2008 Free Software Foundation, Inc. # This file 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. m4_ifndef([AC_AUTOCONF_VERSION], [m4_copy([m4_PACKAGE_VERSION], [AC_AUTOCONF_VERSION])])dnl m4_if(AC_AUTOCONF_VERSION, [2.61],, [m4_warning([this file was generated for autoconf 2.61.

In an in-source build this is usually # harmless because $srcdir is `.', but things will broke when you # start a VPATH build or use an absolute $srcdir. # # So we could use something similar to $top_srcdir/$ac_aux_dir/missing, # iff we strip the leading $srcdir from $ac_aux_dir.

There is no way to easily override this * behavior of the assembler that I am aware of. * * This totally defeats what libmpeg2 is trying to do which is allow a * single binary to be created, and then detect the availability of VIS * at runtime. * * I'm not saying that tainting the binary by default is bad, rather I'm * saying that not providing a way to override this easily unnecessarily * ties people's hands. * * Thus, we do the opcode encoding by hand and output 32-bit words in * the assembler to keep the binary from becoming tainted. */ #ifndef LIBMPEG2_VIS_H #define LIBMPEG2_VIS_H #define vis_opc_base ((0x1 << 31) | (0x36 << 19)) #define vis_opf(X) ((X) << 5) #define vis_sreg(X) (X) #define vis_dreg(X) (((X)&0x1f)|((X)>>5)) #define vis_rs1_s(X) (vis_sreg(X) << 14) #define vis_rs1_d(X) (vis_dreg(X) << 14) #define vis_rs2_s(X) (vis_sreg(X) << 0) #define vis_rs2_d(X) (vis_dreg(X) << 0) #define vis_rd_s(X) (vis_sreg(X) << 25) #define vis_rd_d(X) (vis_dreg(X) << 25) #define vis_ss2s(opf,rs1,rs2,rd) \ __asm__ __volatile__ (".word %0" \ : : "i" (vis_opc_base | vis_opf(opf) | \ vis_rs1_s(rs1) | \ vis_rs2_s(rs2) | \ vis_rd_s(rd))) #define vis_dd2d(opf,rs1,rs2,rd) \ __asm__ __volatile__ (".word %0" \ : : "i" (vis_opc_base | vis_opf(opf) | \ vis_rs1_d(rs1) | \ vis_rs2_d(rs2) | \ vis_rd_d(rd))) #define vis_ss2d(opf,rs1,rs2,rd) \ __asm__ __volatile__ (".word %0" \ : : "i" (vis_opc_base | vis_opf(opf) | \ vis_rs1_s(rs1) | \ vis_rs2_s(rs2) | \ vis_rd_d(rd))) #define vis_sd2d(opf,rs1,rs2,rd) \ __asm__ __volatile__ (".word %0" \ : : "i" (vis_opc_base | vis_opf(opf) | \ vis_rs1_s(rs1) | \ vis_rs2_d(rs2) | \ vis_rd_d(rd))) #define vis_d2s(opf,rs2,rd) \ __asm__ __volatile__ (".word %0" \ : : "i" (vis_opc_base | vis_opf(opf) | \ vis_rs2_d(rs2) | \ vis_rd_s(rd))) #define vis_s2d(opf,rs2,rd) \ __asm__ __volatile__ (".word %0" \ : : "i" (vis_opc_base | vis_opf(opf) | \ vis_rs2_s(rs2) | \ vis_rd_d(rd))) #define vis_d12d(opf,rs1,rd) \ __asm__ __volatile__ (".word %0" \ : : "i" (vis_opc_base | vis_opf(opf) | \ vis_rs1_d(rs1) | \ vis_rd_d(rd))) #define vis_d22d(opf,rs2,rd) \ __asm__ __volatile__ (".word %0" \ : : "i" (vis_opc_base | vis_opf(opf) | \ vis_rs2_d(rs2) | \ vis_rd_d(rd))) #define vis_s12s(opf,rs1,rd) \ __asm__ __volatile__ (".word %0" \ : : "i" (vis_opc_base | vis_opf(opf) | \ vis_rs1_s(rs1) | \ vis_rd_s(rd))) #define vis_s22s(opf,rs2,rd) \ __asm__ __volatile__ (".word %0" \ : : "i" (vis_opc_base | vis_opf(opf) | \ vis_rs2_s(rs2) | \ vis_rd_s(rd))) #define vis_s(opf,rd) \ __asm__ __volatile__ (".word %0" \ : : "i" (vis_opc_base | vis_opf(opf) | \ vis_rd_s(rd))) #define vis_d(opf,rd) \ __asm__ __volatile__ (".word %0" \ : : "i" (vis_opc_base | vis_opf(opf) | \ vis_rd_d(rd))) #define vis_r2m(op,rd,mem) \ __asm__ __volatile__ (#op "\t%%f" #rd ", [%0]" : : "r" (&(mem)) ) #define vis_r2m_2(op,rd,mem1,mem2) \ __asm__ __volatile__ (#op "\t%%f" #rd ", [%0 + %1]" : : "r" (mem1), "r" (mem2) ) #define vis_m2r(op,mem,rd) \ __asm__ __volatile__ (#op "\t[%0], %%f" #rd : : "r" (&(mem)) ) #define vis_m2r_2(op,mem1,mem2,rd) \ __asm__ __volatile__ (#op "\t[%0 + %1], %%f" #rd : : "r" (mem1), "r" (mem2) ) static inline void vis_set_gsr(unsigned int _val) { register unsigned int val asm("g1"); val = _val; __asm__ __volatile__(".word 0xa7804000" : : "r" (val)); } #define VIS_GSR_ALIGNADDR_MASK 0x0000007 #define VIS_GSR_ALIGNADDR_SHIFT 0 #define VIS_GSR_SCALEFACT_MASK 0x0000078 #define VIS_GSR_SCALEFACT_SHIFT 3 #define vis_ld32(mem,rs1) vis_m2r(ld, mem, rs1) #define vis_ld32_2(mem1,mem2,rs1) vis_m2r_2(ld, mem1, mem2, rs1) #define vis_st32(rs1,mem) vis_r2m(st, rs1, mem) #define vis_st32_2(rs1,mem1,mem2) vis_r2m_2(st, rs1, mem1, mem2) #define vis_ld64(mem,rs1) vis_m2r(ldd, mem, rs1) #define vis_ld64_2(mem1,mem2,rs1) vis_m2r_2(ldd, mem1, mem2, rs1) #define vis_st64(rs1,mem) vis_r2m(std, rs1, mem) #define vis_st64_2(rs1,mem1,mem2) vis_r2m_2(std, rs1, mem1, mem2) #define vis_ldblk(mem, rd) \ do { register void *__mem asm("g1"); \ __mem = &(mem); \ __asm__ __volatile__(".word 0xc1985e00 | %1" \ : \ : "r" (__mem), \ "i" (vis_rd_d(rd)) \ : "memory"); \ } while (0) #define vis_stblk(rd, mem) \ do { register void *__mem asm("g1"); \ __mem = &(mem); \ __asm__ __volatile__(".word 0xc1b85e00 | %1" \ : \ : "r" (__mem), \ "i" (vis_rd_d(rd)) \ : "memory"); \ } while (0) #define vis_membar_storestore() \ __asm__ __volatile__(".word 0x8143e008" : : : "memory") #define vis_membar_sync() \ __asm__ __volatile__(".word 0x8143e040" : : : "memory") /* 16 and 32 bit partitioned addition and subtraction.

libmpeg2 changes. * get the official suite of mpeg2 torture tests at http://libmpeg2.sourceforge.net/files/mpeg2dec-streams.tar.gz or using SVN : # svn co svn://svn.videolan.org/libmpeg2/streams (OK, I did some reorganization work on the archive, so it is not really the official suite anymore) Then, * extract this archive at the same level as your mpeg2dec directory : in your working directory you should have subdirectories mpeg2dec and streams. * or, extract this archive where you want, but change the first line of the "tests" file to reflect that location. Do _not_ remove the pound (#) sign at the beginning of the line. Now run test/regression is the name of the test suite you want to use. For the official mpeg video conformance tests, just use "tests". is the type of IDCT you are using. If your machine supports MMX, choose "mmx".

Sorry about that, hope to write something better for the 0.4.1 release. For people migrating code from 0.3.x to 0.4.0, the biggest thing to note is that mpeg2_parse now returns a new state STATE_BUFFER when it needs more data. Version 0.3.x used to return a -1 constant for this - please update your code to replace that -1 with STATE_BUFFER. Otherwise 0.3.x code should mostly work with 0.4.0, hopefully. For people new to libmpeg2, it's best to start by looking at doc/sample1 and doc/sample2, which decode an mpeg2 elementary stream and output their individual pictures as yuv frames (sample1) or rgb frames (sample2). The main loop calls mpeg2_parse() which does some work and then returns a state indicating what it just did - STATE_BUFFER if it reached the end of the buffer and it needs a new one, STATE_SEQUENCE if it just parsed a sequence header, STATE_PICTURE if it just parsed a picture header, STATE_SLICE if it just decoded the slice information associated with a picture (now is a good time to save that decoded picture), etc... To make more complex buffer management (basically allocate your own buffers instead of letting the lib do it for you), look at sample3/sample4 (giving your buffers to the lib at init time but letting the lib chose a buffer for each picture) or sample5/sample6 (giving a new buffer to the lib for each picture). Color conversion has been moved to a new helper library, libmpeg2convert. The details of the mpeg2_convert_t type might change in the future, but what won't change is that you should just take one of the mpeg2_convert_t symbols exported from libmpeg2convert, and pass it to the mpeg2_convert() function, and voila, you now get your output buffers in the desired format. For example if you want rgb 32-bit samples, you just call mpeg2_convert (mpeg2dec, mpeg2convert_rgb32, NULL) and that's it. There is a new mpeg2_stride function too. By default libmpeg2 choses the smallest stride that will work for a given picture size, if you want a larger stride you can set it (after the sequence header has been decoded) by calling mpeg2_stride. There is also a new function mpeg2_reset which should hopefully do the right thing after skipping to a new position in the mpeg2 stream. If full_reset is zero the lib starts decoding at the next picture, if it's one the lib starts looking for the next sequence header. The mpeg2_pts function is gone, because people complained about not being to pass a 33-bit PTS thru it. So instead it's been replaced with mpeg2_tag_picture(), which is identical except that it allows you to pass two 32-bit values. You can use them to form a combined 64-bit time stamp, or two 32-bit PTS/DTS stamps, or whatever you please - libmpeg2 never uses these values, it just passes them around, hence the name "tag". The semantics are what you want for a PTS function though, i.e. the tags get associated to the next picture that starts after the tag was set, where the start of a picture is defined as the first byte of its picture start code. That's all I can think of - sorry for the lack of proper documentation, I'll try to help this before the 0.4.1 release.

To get this handle (of type "mpeg2dec_t"), call "mpeg2_init()". Data is loaded into the decoder with "mpeg2_buffer" whenever "mpeg2_parse" is ready for more data (return state is STATE_BUFFER). Pictures are available whenever "mpeg2_parse"'s return state is STATE_SLICE or STATE_END. This means the *previous* picture is available, right? In other words, when STATE_SLICE is seen, that means that the *previous* picture is all done. Same thing for STATE_END. So if you want to see one frame at a time (without starting to fill the mpeg2 decoder with more data not from that picture) we'd have to inject something to make it report STATE_END? Basic Function Reference ------------------------ mpeg2dec_t * mpeg2_init() Initializes a memory space for mpeg2 decoding. This memory must be freed with a call to "mpeg2_close" when finished. Returns NULL on error (when system is out of memory) - Doesn't check if chunk_buffer is NULL? uint32_t mpeg2_accel(uint32_t accel) Sets the CPU acceleration type to be used for all decoders for the life of the program. YOU CAN SAFELY IGNORE THIS FUNCTION. By default, a call to mpeg2_accel is not needed, since the best available acceleration will be auto-detected. To override the default, this function must be called before any calls to "mpeg2_init". See mpeg2.h for a list of the available accelerations (prefix "MPEG2_ACCEL_..."). After a call to mpeg2_init, mpeg2_accel can be called to find out what the selected acceleration list is. Once the accelerations have been selected (through explicitly requesting one, or through auto-detection) the "accel" parameter will be ignored. Returns selected acceleration list. If the requested acceleration is not available, the function will auto-detect the best available accelerations and return that instead. - Cannot be undone! This should maybe be a part of the mpeg2 structure somehow? const mpeg2_info_t * mpeg2_info(mpeg2dec_t * handle) Gets structure for the mpeg2 decoder's "mpeg2_info_t" structure. This will let you do something (like display!) the decoded pictures with the mpeg2_info_t structure members: display_fbuf: memory area containing the rendered picture information. If this is NULL, no frame is available. display_fbuf->buf: YUV coded pixel data for the picture. display_picture: data structure describing the current picture. see mpeg2.h for more details. sequence: data structure describing the entire current picture sequence: width: picture width in pixels. height: picture height in pixels. see mpeg2.h for more details. user_data: handy place to attach things needed by your program. Must be detached before calling "mpeg2_close". there are more...check mpeg2.h int mpeg2_parse(mpeg2dec_t * handle) Parses available data and returns state of the decoder: STATE_BUFFER: ready for more data. decoder has finished reading the buffer sent with mpeg2_buffer. STATE_SEQUENCE: A sequence header has been found. STATE_SEQUENCE_REPEATED: A repeated sequence header has been found and processed. STATE_GOP: A GOP has been found. STATE_PICTURE: A picture header has been found. STATE_PICTURE_2ND: A second field picture header has been found. STATE_SLICE_1ST: First slice of a multi-field picture has been found. STATE_SLICE: Final slice (multi-field or not) of a picture has been found. Good time to update the display. STATE_END: End of the stream? Good time to update the display. STATE_INVALID: Filled the internal buffers without finding any start codes. Cannot continue: mpeg2_close must be called next. void mpeg2_buffer(mpeg2dec_t * handle, uint8_t * start, uint8_t * end) Makes data between "start" and "end" available for processing. If a subsequent call to "mpeg2_parse" doesn't find anything useful (returns STATE_BUFFER) then this data will be copied into the mpeg2 decoder's private data area. This process repeats until something useful is found with mpeg2_parse (returns something other than STATE_BUFFER), or the buffer fills up. void mpeg2_close(mpeg2dec_t * handle) Cleans up the memory associated with the mpeg2 decoder handle. - does not check for NULL frees!

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.
