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
2011-01-15H.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
2011-01-14H.264: eliminate non-transposed scantable support.Jason Garrett-Glaser
It was an ugly hack to begin with and didn't give any performance. NOTE: this patch opens up some future simplifications to be made (such as removing some of the scantables from H264Context) but doesn't take advantage of them yet. Originally committed as revision 26329 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
2009-02-01Use full internal pathname in doxygen @file directives.Diego Biurrun
Otherwise doxygen complains about ambiguous filenames when files exist under the same name in different subdirectories. Originally committed as revision 16912 to svn://svn.ffmpeg.org/ffmpeg/trunk
