Andreas Rheinhardt	3b67ab85ee	avcodec/mpegvideo_enc: Only keep what is used from MECmpContext A MECmpContext is quite big (792B here) and given how ff_update_duplicate_context() works, it is (unfortunately) copied quite frequently when using slice threading. Therefore keep only what is needed from MECmpContext and remove MECmpContext from MpegEncContext. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>	7 months ago
Martin Storsjö	dc55e63578	x86: Don't hardcode the height to 8 in sad8_xy2_mmx The height is hardcoded in some of the me_cmp functions, but not in all of them. But in the case of all other functions, it's hardcoded in the same place in SIMD functions as in the C reference functions, while this one function differs from the behaviour of the C code. (Before `542765ce3e`, there were a couple other sad8_*_mmx functions with similar hardcoded height.) Signed-off-by: Martin Storsjö <martin@martin.st>	2 years ago
Andreas Rheinhardt	abb85429f3	avcodec/me_cmp: Constify me_cmp_func buffer parameters Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>	3 years ago
Andreas Rheinhardt	542765ce3e	avcodec/x86/me_cmp: Remove obsolete MMX(EXT) functions 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>	3 years ago
Andreas Rheinhardt	645f705d6a	av(codec\|device): Don't cast pointers to int C99/C11 6.3.2.3 5: "Any pointer type may be converted to an integer type. [...] If the result cannot be represented in the integer type, the behavior is undefined." So stop casting pointers to int; use uintptr_t instead.

James Almer	33c752be51	x86/me_cmp: port mmxext vsad functions to yasm Also add mmxext versions of vsad8 and vsad_intra8, and sse2 versions of vsad16 and vsad_intra16.

Diego Biurrun	19e30a58fc	Deprecate obsolete XvMC hardware decoding support XvMC has long ago been superseded by newer acceleration APIs, such as VDPAU, and few downstreams still support it.
