Justin Ruggles	78a9a77eac	add CODEC_CAP_SUBFRAMES to the FLAC decoder capabilities. also add a FIXME comment as a reminder that we can remove both capabilities once a parser is implemented. Originally committed as revision 19891 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	8313e17976	flacdec: change variable-length array to fixed length pred_order can never exceed 32, so always allocating that amount is safe and not very wasteful. Originally committed as revision 19669 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Ronald S. Bultje	ce863d7f36	Rename ff_log_missing_feature() to av_log_missing_feature(). Originally committed as revision 19294 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Stefano Sabatini	9106a698e7	Rename bitstream.h to get_bits.h. Originally committed as revision 18494 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.
