Måns Rullgård	94ca624fbc	Move ff_sqrt() to libavutil/intmath.h Originally committed as revision 22345 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	c26e58e32c	Add some missing #includes Originally committed as revision 22258 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	2c8077621b	Optimize ff_snow_horizontal_compose97i. this makes the 9/7 C wavelet at the decoder side 22% faster. The old code is changed to match the new in terms of the order of operations (which also makes it sligtly faster) Originally committed as revision 21132 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	233a8b3d6b	Merge vertical_compose53iL0*() 8% faster C 5/3 wavelet at the decoder side. Originally committed as revision 21131 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	2a84512a74	Optimize horizontal_compose53i() by inlining inv_lift() and optimizing the resulting code slightly. ~30% faster C 5/3 wavelet at the decoder side. Originally committed as revision 21130 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.
