Martin Storsjö	38b3bda18f	adpcm: Replace any of the leaf nodes in the heap By not looking for the exactly largest node, we avoid an O(n) seek through the leaf nodes. Just pick one (not the same one every time) and try replacing that node with the new one. For -trellis 8, this lowers the run time from 190 to 158 seconds, for a 30 second 44 kHz mono sample, on my machine.

Martin Storsjö	f82e8f3482	adpcm: Store the trellis nodes in a heap instead of a sorted array This avoids having to memmove the large parts of the array when inserting into it. For -trellis 8, this lowers the run time from 245 seconds to 190 seconds, for a 30 second 44 kHz mono sample, on my machine.

Diego Biurrun	ba87f0801d	Remove explicit filename from Doxygen @file commands.

Originally committed as revision 22921 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Stefano Sabatini	72415b2adb	Define AVMediaType enum, and use it instead of enum CodecType, which is deprecated and will be dropped at the next major bump. Originally committed as revision 22735 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	9f72b23c5c	Revert Revision: 21362 Log: Set CODEC_CAP_SUBFRAMES for adpcm decoders This makes ffmpeg stop printing millions of Multiple frames in a packet from stream 0 when decoding adpcm. Reason: adpcm has no subframes, the flag does not belong there Originally committed as revision 21481 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 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.
