* vc-1: Add platform-specific start code search routine to VC1DSPContext.Ben Avison2014-08-04
| | | | | | | Initialise VC1DSPContext for parser as well as for decoder. Note, the VC-1 code doesn't actually use the function pointer yet. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
* vc1dsp: Add wrappers for {avg|put}_vc1_mspel_mc00_cDiego Biurrun2014-07-25
| | | | This avoids invoking the wrapped functions with too many arguments.
* dsputil: Split off quarterpel bits into their own contextDiego Biurrun2014-05-29
|
* Remove a number of unnecessary dsputil.h #includesDiego Biurrun2014-04-04
|
* aarch64: h264 chroma motion compensation NEON optimizationsJanne Grunau2014-01-15
| | | | | Since RV40 and VC-1 use almost the same algorithm so optimizations for those two decoders are easy to do and included.
* vc1: Add avg_no_rnd_vc1_chroma_mc4_c()Michael Niedermayer2014-01-13
| | | | | | Needed for proper interlaced support. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>

* dsputil: Separate h264chromaDiego Biurrun2013-02-06
|
* Drop DCTELEM typedefDiego Biurrun2013-01-22
| | | | | | It does not help as an abstraction and adds dsputil dependencies. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>
* x86: vc1: call ff_vc1dsp_init_x86() under if (ARCH_X86)Janne Grunau2012-10-08

* vc1dsp: mark put/avg_vc1_mspel_mc() always_inlineMans Rullgard2012-06-08
| | | | | | | | | | 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>
* Don't use ff_cropTbl[] for IDCT.Ronald S. Bultje2012-03-06
| | | | | | | | 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
* Remove extraneous semicolonsMans Rullgard2011-12-11
| | | | | | These semicolons cause invalid empty top-level declarations. Signed-off-by: Mans Rullgard <mans@mansr.com>
* vc1dec: interlaced stream decoding support 3/3Mashiat Sarker Shakkhar2011-10-10
| | | | | | Cosmetics: break some lines and reformat TODOs Signed-off-by: Anton Khirnov <anton@khirnov.net>

* vc1: make overlap filter for I-frames bit-exact.Ronald S. Bultje2011-05-04
|
* Revert "VC1: merge idct8x8, coeff adjustments and put_pixels."Ronald S. Bultje2011-05-04
| | | | | | | 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.
* Replace FFmpeg with Libav in licence headersMans Rullgard2011-03-19

* VC1: merge idct8x8, coeff adjustments and put_pixels.Ronald S. Bultje2011-02-21
| | | | | Merging these functions allows merging some loops, which makes the results (particularly after SIMD optimizations) much faster.
* dsputil: move VC1-specific stuff into VC1DSPContext.Ronald S. Bultje2011-02-17

* VC1: transpose IDCT 8x8 coeffs while reading.Ronald S. Bultje2011-02-17
|
* Remove duplicate definitions of fullpel MC functionsMåns Rullgård2010-08-25
| | | | | | | 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
* Improve some uses of ff_cropTbl with constant offsetMåns Rullgård2010-06-22
| | | | Originally committed as revision 23728 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Remove explicit filename from Doxygen @file commands.Diego Biurrun2010-04-20
| | | | | | | | 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
* Move some VC1 dsp prototypes to dsputil.h; they are defined in dsputil.cMåns Rullgård2010-03-06
| | | | | | Also fix function definitions to match prototypes (missing const). Originally committed as revision 22263 to svn://svn.ffmpeg.org/ffmpeg/trunk
* More av_cold for infrequently called functions.Zuxy Meng2010-01-13
| | | | Originally committed as revision 21179 to svn://svn.ffmpeg.org/ffmpeg/trunk
* idct_dc for VC-1/WMV3 decoder; ~11% faster decoding overall.Jason Garrett-Glaser2009-06-16
| | | | | | | | | 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

* Use full internal pathname in doxygen @file directives.Diego Biurrun2009-02-01
