Janne Grunau	71617884a2	aarch64: h264 chroma motion compensation NEON optimizations Since RV40 and VC-1 use almost the same algorithm so optimizations for those two decoders are easy to do and included.	11 years ago
Michael Niedermayer	6d98959c8a	vc1: Add avg_no_rnd_vc1_chroma_mc4_c() Needed for proper interlaced support. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	11 years ago

Diego Biurrun	88bd7fdc82	Drop DCTELEM typedef It does not help as an abstraction and adds dsputil dependencies. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	12 years ago

Mans Rullgard	bc92214e27	vc1dsp: mark put/avg_vc1_mspel_mc() always_inline This ensures that these functions are inlined into the per-position entry points, allowing constant propagation as needed for proper optimisation. 18% faster VC1 decoding on Cortex-A9. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Ronald S. Bultje	c23acbaed4	Don't use ff_cropTbl[] for IDCT. Results of IDCT can by far outreach the range of ff_cropTbl[], leading to overreads and potentially crashes. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org	13 years ago

Ronald S. Bultje	7d2e03afc8	vc1: make overlap filter for I-frames bit-exact.	14 years ago
Ronald S. Bultje	18b6a69ce9	Revert "VC1: merge idct8x8, coeff adjustments and put_pixels." This reverts commit `f8bed30d8b`. 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.	14 years ago
Mans Rullgard	2912e87a6c	Replace FFmpeg with Libav in licence headers Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Ronald S. Bultje	6a786b15c3	VC1: merge idct8x8, coeff adjustments and put_pixels. Merging these functions allows merging some loops, which makes the results (particularly after SIMD optimizations) much faster. (cherry picked from commit `f8bed30d8b`)	14 years ago

Måns Rullgård	3d1b1caa6b	Remove duplicate definitions of fullpel MC functions 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	15 years ago
Måns Rullgård	8fbd4f51a8	Improve some uses of ff_cropTbl with constant offset Originally committed as revision 23728 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Diego Biurrun	ba87f0801d	Remove explicit filename from Doxygen @file commands. 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	15 years ago
Måns Rullgård	4f602a0415	Move some VC1 dsp prototypes to dsputil.h; they are defined in dsputil.c Also fix function definitions to match prototypes (missing const). Originally committed as revision 22263 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Zuxy Meng	0752cd39d2	More av_cold for infrequently called functions. Originally committed as revision 21179 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Jason Garrett-Glaser	4f717c69ed	idct_dc for VC-1/WMV3 decoder; ~11% faster decoding overall. 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).

Diego Biurrun	bad5537e2c	Use full internal pathname in doxygen @file directives. 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	16 years ago
