2009-04-07Implement avcodec_decode_video2(), _audio3() and _subtitle2() which takes anThilo Borgmann
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
2009-03-02Call ff_fetch_timestamp() for mpeg1/2 when a picture start code is found insteadMichael Niedermayer
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
