Zhao Zhili	e18b46d95f	swscale/aarch64: Fix rgb24toyv12 only works with aligned width Since `c0666d8b`, rgb24toyv12 is broken for width non-aligned to 16. Add a simple wrapper to handle the non-aligned part. Co-authored-by: johzzy <hellojinqiang@gmail.com> Signed-off-by: Zhao Zhili <zhilizhao@tencent.com>	4 months ago

Ramiro Polla	d8848325a6	swscale/aarch64/rgb2rgb: add deinterleaveBytes neon implementation A55 A76 deinterleave_bytes_c: 70342.0 34497.5 deinterleave_bytes_neon: 21594.5 ( 3.26x) 5535.2 ( 6.23x) deinterleave_bytes_aligned_c: 71340.8 34651.2 deinterleave_bytes_aligned_neon: 8616.8 ( 8.28x) 3996.2 ( 8.67x)	4 months ago
Martin Storsjö	e0604d508e	swscale: aarch64: Add a NEON implementation of interleaveBytes This allows speeding up format conversions from yuv420 to nv12.

Janne Grunau	3956a5e0ea	aarch64: NEON vorbis_inverse_coupling From the ARMv7 NEON version. 16 times faster as the C version, overall more than 12% faster vorbis decoding on Apple's A7.	11 years ago
Diego Biurrun	c9f933b5b6	Add av_cold attributes to arch-specific init functions	12 years ago
Ronald S. Bultje	1768e43ceb	vorbisdsp: change block_size type from int to intptr_t. This saves one instruction in the x86-64 assembly.	12 years ago
Ronald S. Bultje	fef906c77c	Move vorbis_inverse_coupling from dsputil to vorbisdspcontext. Conveniently (together with Justin's earlier patches), this makes our vorbis decoder entirely independent of dsputil.	12 years ago
Mans Rullgard	d526c5338d	ARM: allow runtime masking of CPU features This allows masking CPU features with the -cpuflags avconv option which is useful for testing different optimisations without rebuilding. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Diego Biurrun	3dde147ff9	cosmetics: Consistently place static, inline and av_cold attributes/keywords.	13 years ago

Måns Rullgård	2ed6f39944	Replace many includes of libavutil/common.h with what is actually needed This reduces the number of false dependencies on header files and speeds up compilation. Originally committed as revision 22407 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago

Måns Rullgård	544f5a922f	Optimise av_log2 with clz when available 10% faster flac decoding on x86 and ARM. Originally committed as revision 21217 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Stefano Sabatini	987903826b	Globally rename the header inclusion guard names. Consistently apply this rule: the guard name is obtained from the filename by stripping the leading "lib", converting '/' and '.' to '_' and uppercasing the resulting name. Guard names in the root directory have to be prefixed by "FFMPEG_". Originally committed as revision 15120 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
Måns Rullgård	3540b950ec	add missing #include "common.h" to libavutil headers Originally committed as revision 12502 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago

Diego Biurrun	b78e7197a8	Change license headers to say 'FFmpeg' instead of 'this program/this library' and fix GPL/LGPL version mismatches. Originally committed as revision 6577 to svn://svn.ffmpeg.org/ffmpeg/trunk	19 years ago
Diego Biurrun	04d7f60143	Add official LGPL license headers to the files that were missing them. Originally committed as revision 6219 to svn://svn.ffmpeg.org/ffmpeg/trunk	19 years ago
