Michael Niedermayer	fa6fa2162b	avcodec/cabac: support UNCHECKED_BITSTREAM_READER = 0 Fixes overreads in HEVC Fixes Ticket3070 Also fixed remaining issues from Ticket3075 and Ticket3076 Some lines of code taken from 0c5f839693da2276c2da23400f67a67be4ea0af1:libavcodec/x86/cabac.h and 0c5f839693da2276c2da23400f67a67be4ea0af1:libavcodec/cabac_functions.h Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Ronald S. Bultje	960490c0b2	avcodec/x86/videodsp: Small speedups in ff_emulated_edge_mc x86 SIMD. Don't use word-size multiplications if size == 2, and if we're using SIMD instructions (size >= 8), complete leftover 4byte sets using movd, not mov. Both of these changes lead to minor speedups.

Ronald S. Bultje	cd86eb265f	avcodec/x86/videodsp: fix a bug in a %if statement where we used '%%' instead of '&&'. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Michael Niedermayer	41efb8d9a7	avcodec/x86/cabac: include get_cabac_bypass_sign_x86() under #if !BROKEN_COMPILER this might fix Ticket2999 as well as some fate clients untested as the original patch submitter no longer has the environment to test this should be reverted if it does not fix the issues Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Ronald S. Bultje	1b3a7e1f42	avcodec/x86/videodsp: Properly mark sse2 instructions in emulated_edge_mc x86 simd as such. Should fix crashes or corrupt output on pre-SSE2 CPUs when they were using SSE2-code (e.g. AMD Athlon XP 2400+ or Intel Pentium III) in hfix or hvar single-edge (left/right) extension functions.

Michael Niedermayer	c35d29a9c8	avcodec/x86/dsputil_init: move ff_idct_xvid_mmxext init This decreases the diff to libav Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago

Henrik Gramner	bbe4a6db44	x86inc: Utilize the shadow space on 64-bit Windows Store XMM6 and XMM7 in the shadow space in functions that clobbers them. This way we don't have to adjust the stack pointer as often, reducing the number of instructions as well as code size. Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>	12 years ago
Diego Biurrun	ce1e8045e0	x86: fdct: Employ more specific ifdefs This avoids building mmxext and sse2 code when disabled by configure.	12 years ago
Diego Biurrun	2ddb35b911	x86: dsputil: Separate ff_add_hfyu_median_prediction_cmov from dsputil_mmx The function does not depend on MMX and compilation without MMX enabled fails if the function is compiled conditional on MMX availability.	12 years ago

Ronald S. Bultje	f1548c008f	Full-pixel MC functions. Decoding time of ped1080p.webm goes from 11.3sec to 11.1sec.	12 years ago
Ronald S. Bultje	c07ac8d467	VP9 MC (ssse3) optimizations. Decoding time of ped1080p.webm goes from 20.7sec to 11.3sec.	12 years ago
Ronald S. Bultje	face578d56	Rewrite emu_edge functions to have separate src/dst_stride arguments. This allows supporting files for which the image stride is smaller than the max. block size + number of subpel mc taps, e.g. a 64x64 VP9 file or a 16x16 VP8 file with -fflags +emu_edge.	12 years ago
Ronald S. Bultje	c341f734e5	Convert multiplier for MV from int to ptrdiff_t. This prevents emulated_edge_mc from not undoing mvy*stride-related integer overflows. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Martin Storsjö	ede42109e7	x86: Add an xmm clobbering wrapper for avcodec_encode_video2 This is required since `187105ff8` when we started trying to wrap this function as well. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago

Hendrik Leppkes	a06a5b78e2	mathops/x86: work around inline asm miscompilation with GCC 4.8.1 The volatile is not required here, and prevents a miscompilation with GCC 4.8.1 when building on x86 with --cpu=i686 Signed-off-by: Michael Niedermayer <michaelni@gmx.at> Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>	12 years ago
Michael Niedermayer	2ffead98dd	avcodec: add emuedge_linesize_type Currently all uses of the emu edge code as well as the code itself assume int linesize changing some but not changing all would introduce a security issue once all use this typedef a simple search and replace can be done to switch them all to ptrdiff_t Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago

Diego Biurrun	8506ff97c9	vp56: Mark VP6-only optimizations as such. Most of our VP56 optimizations are VP6-only and will stay that way. So avoid compiling them for VP5-only builds.	12 years ago
