2011-05-04vc1: make overlap filter for I-frames bit-exact.Ronald S. Bultje
2011-05-04Revert "VC1: merge idct8x8, coeff adjustments and put_pixels."Ronald S. Bultje
This reverts commit f8bed30d8b176fa030f6737765338bb4a2bcabc9. The reason for this is that the overlap filter, which runs after IDCT, should run on unclamped values, and thus IDCT and put_pixels() cannot be merged if we want to attempt to be bitexact.

2011-02-21VC1: merge idct8x8, coeff adjustments and put_pixels.Ronald S. Bultje
Merging these functions allows merging some loops, which makes the results (particularly after SIMD optimizations) much faster.
2011-02-18dsputil: move VC1-specific stuff into VC1DSPContext.Ronald S. Bultje
2011-02-18VC1: transpose IDCT 8x8 coeffs while reading.Ronald S. Bultje
2010-08-26Remove duplicate definitions of fullpel MC functionsMåns Rullgård
This removes duplicated definitions of 8x8 and 16x16 fullpel MC functions with various names reducing dsputil.o by 8k on x86_64. Originally committed as revision 24933 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-06-23Improve some uses of ff_cropTbl with constant offsetMåns Rullgård
Originally committed as revision 23728 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
2010-03-07Move some VC1 dsp prototypes to dsputil.h; they are defined in dsputil.cMåns Rullgård
Also fix function definitions to match prototypes (missing const). Originally committed as revision 22263 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-01-13More av_cold for infrequently called functions.Zuxy Meng
Originally committed as revision 21179 to svn://svn.ffmpeg.org/ffmpeg/trunk
2009-06-16idct_dc for VC-1/WMV3 decoder; ~11% faster decoding overall.Jason Garrett-Glaser
Includes mmx2 asm for the various functions. Note that the actual idct still does not have an x86 SIMD implemtation. For wmv3 files using regular idct, the decoder just falls back to simple_idct, since simple_idct_dc doesn't exist (yet). Originally committed as revision 19204 to svn://svn.ffmpeg.org/ffmpeg/trunk

2009-02-01Use full internal pathname in doxygen @file directives.Diego Biurrun
