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.

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.

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.

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.

documentation is currently a mess. 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. + + + + + + +I - simplest example + +explanation of sequence_t, picture_t fields + +II - w/ color conversion + +III - pts + +IV - app that preallocates buffers + +V - app that does its own buffer management + + + + + +Quick-and-dirty documentation for libmpeg2 0.3.1 +Kees Cook +2003-04-25 + + + +Basic Usage Pseudocode +---------------------- + + if (you need a certain acceleration) + mpeg2_accel(desired_acceleration); + handle=mpeg2_init(); + info=mpeg2_info(handle); + while (data_available) { + state=mpeg2_parse(handle); + switch (state) { + case STATE_BUFFER: + read some data + mpeg2_buffer(handle,data_start,data_end); + break; + case STATE_SLICE: + case STATE_END: + display the frame described in "info" + break; + case STATE_INVALID: + abort + break; + } + } + mpeg2_close(handle); + + +Basic Usage Explained +--------------------- + +libmpeg2 uses an opaque pointer which is the active "handle" to the mpeg2 +decoder. 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.

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.
