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 |
