2011-01-21Revert 2a1f431d38ea9c05abb215d70c7dc09cdb6888ab, it broke H264 lossless.Ronald S. Bultje
(cherry picked from commit 66c6b5e2a5e6376c4a5c65b1d96fd7a1580bdfcf)
2011-01-15H.264/SVQ3: make chroma DC work the same way as luma DCJason Garrett-Glaser
No speed improvement, but necessary for some future stuff. Also opens up the possibility of asm chroma dc idct/dequant. Originally committed as revision 26349 to svn://svn.ffmpeg.org/ffmpeg/trunk
2011-01-15Remove outdated comment in h264dsp.hJason Garrett-Glaser
Since we no longer have non-transposed scantables, the problem it warns about no longer exists. Originally committed as revision 26339 to svn://svn.ffmpeg.org/ffmpeg/trunk
2011-01-15H.264: split luma dc idct out and implement MMX/SSE2 versionsJason Garrett-Glaser
About 2.5x the speed. NOTE: the way that the asm code handles large qmuls is a bit suboptimal. If x264-style dequant was used (separate shift and qmul values), it might be possible to get some extra speed. Originally committed as revision 26336 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-04-20Remove explicit filename from Doxygen @file commands.Diego Biurrun
Passing an explicit filename to this command is only necessary if the documentation in the @file block refers to a file different from the one the block resides in. Originally committed as revision 22921 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-03-16Move H264 dsputil functions into their own structMåns Rullgård
This moves the H264-specific functions from DSPContext to the new H264DSPContext. The code is made conditional on CONFIG_H264DSP which is set by the codecs requiring it. The qpel and chroma MC functions are not moved as these are used by non-h264 code. Originally committed as revision 22565 to svn://svn.ffmpeg.org/ffmpeg/trunk
