Juanjo	4b1f4f236b	- Versions defined for libav/libavcodec. - Bug fix in wav muxer for MP2 audio. - ffmpeg/libavcodec version in MPEG-4 user data. Originally committed as revision 400 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
Juanjo	10bb7023a2	- Added force_pts to av_write_packet() to be able to force PTS, this helps (and fix) stream copying. By now force_pts it's just honoured by the MPEG muxer. ASF could honour this also, but it should be fixed to use Tickers first. - MPEG audio decoder exports it's frame size in bytes. - Hope this fix the floating point exception found in ffserver. Originally committed as revision 382 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
Michael Niedermayer	27a3e2c5e0	another bitstream reader code (faster on intel cpus) - patch by Michael Niedermayer <michaelni@gmx.at> Originally committed as revision 252 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
