Michael Niedermayer	0398717356	passing avctx->flags so that grayscale only decoding works with mpeg1/2 too Originally committed as revision 678 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
Fabrice Bellard	ff4ec49e64	license/copyright change Originally committed as revision 599 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
Fabrice Bellard	fb4a4a5607	mpeg1/2 identifier - fixed frame rate for some bad mpeg1 streams Originally committed as revision 542 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
Fabrice Bellard	5bd12d1277	improved mpeg1/2 decoding speed Originally committed as revision 517 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
Juanjo	e0a3d744a0	- repeat_pict meaning changed, now it signals the extra delay for the decoded frame. - extra_delay = (repeat_pict / 2) * (1/fps) Originally committed as revision 496 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
Juanjo	c80340a4eb	- repeat_pict added to AVCodecContext to signal if the decoder must repeat frames from 3:2 pulldown sources. - repeat_pict honoured by MPEG-1/2 decoder. Originally committed as revision 486 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
Juanjo	bc6caae212	- MPEG-4 B frames coding option for ffmpeg.c - Warning fixes. Originally committed as revision 448 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
Michael Niedermayer	2417652e9f	export mbskip_table for direct rendering add hurry_up support Originally committed as revision 424 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
Michael Niedermayer	d7e9533aa0	fixed msmpeg4 infinite loop if buggy stream rewrote quantizer fixed bias (+10% compression/quality for h263 like codecs) qscale=1 support mpeg1 intra frames looks far less blocky added codec_id field Originally committed as revision 423 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.
