Justin Ruggles	b57e38f52c	ac3dsp: x86: Replace inline asm for in-decoder downmixing with standalone asm Adds a wrapper function for downmixing which detects channel count changes and updates the selected downmix function accordingly. Simplification and porting to current x86inc infrastructure by Diego Biurrun. Signed-off-by: Diego Biurrun <diego@biurrun.de>	8 years ago
Justin Ruggles	43717469f9	ac3dsp: Reverse matrix in/out order in downmix() Also use (float *) instead of (float ()[2]). This matches the matrix layout in libavresample so we can reuse assembly code between the two. Signed-off-by: Diego Biurrun <diego@biurrun.de>	8 years ago
Hendrik Leppkes	8d1267932c	x86/h264_weight: use appropriate register size for weight parameters This fixes decoding corruption on 64 bit windows. Signed-off-by: Martin Storsjö <martin@martin.st>	8 years ago
Diego Biurrun	2caa93b813	mpegaudiodsp: Change type of array stride parameters to ptrdiff_t This avoids SIMD-optimized functions having to sign-extend their stride argument manually to be able to do pointer arithmetic.	8 years ago
Diego Biurrun	e4a94d8b36	h264chroma: Change type of stride parameters to ptrdiff_t This avoids SIMD-optimized functions having to sign-extend their stride argument manually to be able to do pointer arithmetic.	8 years ago
Diego Biurrun	2ec9fa5ec6	idct: Change type of array stride parameters to ptrdiff_t ptrdiff_t is the correct type for array strides and similar.	8 years ago

Anton Khirnov	683da86aab	audiodsp: reorder arguments for vector_clipf This will make the x86 asm simpler. ARM conversion by Martin Storsjö <martin@martin.st> and Janne Grunau <janne-libav@jannau.net>	8 years ago
Anton Khirnov	eea9857bfd	blockdsp: drop the high_bit_depth parameter It has no effect, since the code is supposed to operate the same way for any bit depth.	8 years ago
Anton Khirnov	75d98e30af	audiodsp/x86: clear the high bits of the order parameter on 64bit Also change shl to add, since it can be faster on some CPUs. CC: libav-stable@libav.org	8 years ago
Anton Khirnov	1d6c76e11f	audiodsp/x86: fix ff_vector_clip_int32_sse2 This version, which is the only one doing two processing cycles per loop iteration, computes the load/store indices incorrectly for the second cycle. CC: libav-stable@libav.org	8 years ago
Diego Biurrun	de452e5037	pixblockdsp: Change type of stride parameters to ptrdiff_t This avoids SIMD-optimized functions having to sign-extend their line size argument manually to be able to do pointer arithmetic. Also adjust parameter names to be "stride" everywhere.	9 years ago
Diego Biurrun	721d57e608	vp56: Separate VP5 and VP6 dsp initialization VP5 has no arch-specific optimizations (nor will it get some in the future), so it makes no sense to try to share dsp init code with VP6.	9 years ago
Diego Biurrun	3fd22538bc	prores: Change type of stride parameters to ptrdiff_t This avoids SIMD-optimized functions having to sign-extend their line size argument manually to be able to do pointer arithmetic. Also adjust parameter names to be "linesize" everywhere.	9 years ago

Ronald S. Bultje	9790b44a89	vp9mc/x86: sse2 MC assembly. Also a slight change to the ssse3 code, which prevents a theoretical overflow in the sharp filter. Signed-off-by: Anton Khirnov <anton@khirnov.net>	9 years ago
