Michael Niedermayer	483aad717e	slif aka "SoftLab MPEG-2 I-frames Codec" support. Flipping one bit still is popular it seems as a means to create a new codec. fixes issue1469. Originally committed as revision 20679 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	52069c4d3c	Move "slice below image" check from mpeg_decode_slice to its caller. Should fix issue1277. Originally committed as revision 20676 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago

Michael Niedermayer	078cdecf9e	Set mb_y in mpeg2 field pictures like h264 does. This fixes -vismv & -debug 16384 with field pictures. Originally committed as revision 20670 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	ab8c48de8c	Start decoding from seq/gop too, not just I frames. Possibly fixes issue1124. Originally committed as revision 20667 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago

Baptiste Coudurier	a4a750d3b2	Rename alloc_picture to ff_alloc_picture and move its definition in mpegvideo.h to avoid including mpegvideo_common.h in mpeg12.c, because it contains motion code. Originally committed as revision 18968 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago

Thilo Borgmann	7a00bbad21	Implement avcodec_decode_video2(), _audio3() and _subtitle2() which takes an AVPacket argument rather than a const uint8_t *buf + int buf_size. This allows passing of packet-specific flags from demuxer to decoder, such as the keyframe flag, which appears necessary to playback corePNG P-frames. Patch by Thilo Borgmann thilo.borgmann googlemail com, see also the thread "Google Summer of Code participation" on the mailinglist. Originally committed as revision 18351 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Michael Niedermayer	a4c7a5ea27	Call ff_fetch_timestamp() for mpeg1/2 when a picture start code is found instead of calling it at the end of a frame with a large negative offset. This significantly reduces the maximal distance in container packets between the point where the first byte of the "access unit" was stored and where we call ff_fetch_timestamp() thus reducing the constraints on our parser. Also change the parser from next_frame_offset to cur, this is needed because now the reference is from container packet start instead of frame start. (i previously misinterpreted this as bug) Originally committed as revision 17731 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
