* Optimize ff_snow_horizontal_compose97i.Michael Niedermayer2010-01-11
| | | | | | | | 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
* Merge vertical_compose53iL0*()Michael Niedermayer2010-01-11
| | | | | | 8% faster C 5/3 wavelet at the decoder side. Originally committed as revision 21131 to svn://svn.ffmpeg.org/ffmpeg/trunk

| | | | | | | | | | | 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.
