* avcodec/h264chroma: Constify src in h264_chroma_mc_funcAndreas Rheinhardt2022-08-051-4/+4

* avcodec/x86/vc1dsp_init: Remove obsolete 3dnow, MMX(EXT) functionsAndreas Rheinhardt2022-06-221-26/+14
| | | | | | | | | | | x64 always has MMX, MMXEXT, SSE and SSE2 and this means that some functions for MMX, MMXEXT and 3dnow are always overridden by other functions (unless one e.g. explicitly disables SSE2) for x64. So given that the only systems that benefit from these functions are truely ancient 32bit x86s they are removed. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* vc1dsp: Change remaining stride parameters to ptrdiff_tMartin Storsjö2022-03-301-8/+8
| | | | | | | | | | | The existing x86 assembly for loop filters uses the stride as a full register without clearing/sign extending the upper half of the registers on x86_64. This avoids crashes if the caller would have passed nonzero bits in the previously undefined upper 32 bits of the parameters. Signed-off-by: Martin Storsjö <martin@martin.st>
* build: Generalize yasm/nasm-related variable namesDiego Biurrun2017-06-211-4/+4
| | | | | | | | None of them are specific to the YASM assembler. (Cherry-picked from libav commit 39e208f4d4756367c7cd2d581847e0c1b8a429c1) Signed-off-by: James Almer <jamrial@gmail.com>
* avcodec/x86/vc1dsp_init: Fix build failure with --disable-optimizations and ↵Michael Niedermayer2017-04-271-2/+4
| | | | | | | | | clang compilers doing DCE at -O0 do not necessarily understand "complex" boolean expressions Build succeeds with this change, this was the only failure Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>

| * h264chroma: Change type of stride parameters to ptrdiff_tDiego Biurrun2016-09-291-5/+5
| | | | | | | | | | This avoids SIMD-optimized functions having to sign-extend their stride argument manually to be able to do pointer arithmetic.

* | x86: vc1dsp_mmx: Move yasm initiation steps to vc1dsp_initTimothy Gu2015-10-191-11/+25
| | | | | | | | | | That's where all yasm initiation steps are. Also removes the overlap between the two files.

* | vc1dsp: introduce cases for 8x8 and 16x16Christophe Gisquet2014-04-201-1/+21
| | | | | | | | | | | | | | | | | | | | | | | | This allows further unrolling the DSP implementation where possible. x86 and ARM DSP modified by simply moving the multiple calls from vc1dec to the DSP code. Decoding improvements should only occurs because of the compiler actually able to unroll more. Decoding time: ~8.80s -> 8.64s (ie around 2%) Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
