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
Xiaolei Yu	5a70e56f2f	avcodec: fix vc1dsp dependencies	8 years ago
Janne Grunau	f23d26a686	h264: avoid using uninitialized memory in NEON chroma mc Adapt commit `982b596ea6` for the arm and aarch64 NEON asm. 5-10% faster on Cortex-A9.	11 years ago
Mason Carter	b254490bda	vc1: arm: Add NEON no_rnd chroma MC Apply David Conrad's old patch to the modern codebase. http://ffmpeg.org/pipermail/ffmpeg-devel/2009-April/059877.html Signed-off-by: Martin Storsjö <martin@martin.st>	11 years ago
Thilo Borgmann	d814a839ac	Reinstate proper FFmpeg license for all files.	11 years ago
Diego Biurrun	f407856968	arm: h264chroma: Do not compile h264_chroma_mc* dependent on h264 decoder The functions are used by all codecs that enable the h264chroma component and the file is already compiled conditional on h264chroma being enabled.	11 years ago
Mans Rullgard	1846ddf0a7	ARM: fix overreads in neon h264 chroma mc The loops were reading ahead one line, which could end up outside the buffer for reference blocks at the edge of the picture. Removing this readahead has no measurable performance impact. Signed-off-by: Mans Rullgard <mans@mansr.com>	12 years ago
Michael Niedermayer	3b92075e6c	Revert "arm/h264: fix overreads in h264_chroma_mc8-and-h264_chroma_mc4" This reverts commit `d25f87f517`. This breaks decoding of some h264 files I have tested the original patch with fate but by mistake have forgotten to specify the fate samples so testing was limited to the internal regression tests.	12 years ago
bruce-wu	d25f87f517	arm/h264: fix overreads in h264_chroma_mc8-and-h264_chroma_mc4 Fixes Ticket1227	12 years ago
Mans Rullgard	998170913c	ARM: use standard syntax for all LDRD/STRD instructions The standard syntax requires two destination registers for LDRD/STRD instructions. Some versions of the GNU assembler allow using only one with the second implicit, others are more strict. Signed-off-by: Mans Rullgard <mans@mansr.com>	12 years ago
Justin Ruggles	94d2b0d2fd	ARM: Move asm.S from libavcodec to libavutil This will allow for easier implementation of ARM-optimized functions in libraries other than libavcodec.	13 years ago
Janne Grunau	f5c05b9aa5	rv40: NEON optimised chroma MC Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Mans Rullgard	f054a82727	ARM: move NEON H264 chroma mc to a separate file This allows sharing code with the rv40 version of these functions. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
