* avcodec/h264chroma: Constify src in h264_chroma_mc_funcAndreas Rheinhardt2022-08-05

* all: Replace if (ARCH_FOO) checks by #if ARCH_FOOAndreas Rheinhardt2022-06-15
| | | | | | | | | | | | | | | | | | This is more spec-compliant because it does not rely on dead-code elimination by the compiler. Especially MSVC has problems with this, as can be seen in https://ffmpeg.org/pipermail/ffmpeg-devel/2022-May/296373.html or https://ffmpeg.org/pipermail/ffmpeg-devel/2022-May/297022.html This commit does not eliminate every instance where we rely on dead code elimination: It only tackles branching to the initialization of arch-specific dsp code, not e.g. all uses of CONFIG_ and HAVE_ checks. But maybe it is already enough to compile FFmpeg with MSVC with whole-programm-optimizations enabled (if one does not disable too many components).

* avcodec/vc1: Introduce fast path for unescaping bitstream bufferBen Avison2022-04-01

* vc1dsp: Change remaining stride parameters to ptrdiff_tMartin Storsjö2022-03-30
| | | | | | | | | | | 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>
* configure: Use a separate config_components.h header for $ALL_COMPONENTSMartin Storsjö2022-03-16
| | | | | | | | This avoids unnecessary rebuilds of most source files if only the list of enabled components has changed, but not the other properties of the build, set in config.h. Signed-off-by: Martin Storsjö <martin@martin.st>

* avcodec/vc1: fix overlap filter for frame interlaced picturesJerome Borsboom2018-06-29
| | | | | | | | | | The overlap filter is not correct for vertical edges in frame interlaced I and P pictures. When filtering macroblocks with different FIELDTX values, we have to match the lines at both sides of the vertical border. In addition, we have to use the correct rounding values, depending on the line we are filtering. Signed-off-by: Jerome Borsboom <jerome.borsboom@carpalis.nl>

| | | | | | | | | | | | | | | | | | | | | | | | 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>
