* 4:4:4 H.264 decoding supportJason Garrett-Glaser2011-06-13
| | | | Note: this is 4:4:4 from the 2007 spec revision, not the previous (now deprecated) 4:4:4 mode in H.264.
* Roll back 4:4:4 H.264 for nowJason Garrett-Glaser2011-06-13
| | | | Needs some ARM/PPC asm modifications.

* Add ff_ prefix to data symbols of encoders, decoders, hwaccel, parsers, bsf.Diego Elio Pettenò2011-01-26
| | | | | | | None of these symbols should be accessed directly, so declare them as hidden. Signed-off-by: Mans Rullgard <mans@mansr.com>
* snow: remove unused parameter to mc_block()Måns Rullgård2010-06-23
| | | | Originally committed as revision 23746 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Define AVMediaType enum, and use it instead of enum CodecType, whichStefano Sabatini2010-03-30
| | | | | | is deprecated and will be dropped at the next major bump. Originally committed as revision 22735 to svn://svn.ffmpeg.org/ffmpeg/trunk

| | | | Originally committed as revision 22523 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Separate DWT from snow and dsputilMåns Rullgård2010-03-14
| | | | | | | | This moves the DWT functions from snow.c and dsputil.c to a file of their own. A new struct, DWTContext, holds the function pointers previously part of DSPContext. Originally committed as revision 22522 to svn://svn.ffmpeg.org/ffmpeg/trunk

* 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
* Optimize horizontal_compose53i() by inlining inv_lift() and optimizing theMichael Niedermayer2010-01-11
| | | | | | 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

* Implement avcodec_decode_video2(), _audio3() and _subtitle2() which takes anThilo Borgmann2009-04-07
| | | | | | | | | | | 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.
