J. Dekker	d957ee34a6	lavc/aarch64: fix hevc sao band filter The SAO band filter can be called with non-multiples of 8, we round up to the nearest multiple of 8 to account for this. Signed-off-by: J. Dekker <jdek@itanimul.li>	3 years ago
Martin Storsjö	24b93022fe	aarch64: Disable ff_hevc_sao_band_filter_8x8_8_neon out of precaution While this function on its own passes all of fate-hevc, there's indications that the function might need to handle widths that aren't a multiple of 8 (noted in commit `f63f9be37c`, which later was reverted).

Reimar Döffinger	00c916ef61	lavc/aarch64: port HEVC add_residual NEON Speedup is fairly small, around 1.5%, but these are fairly simple. Signed-off-by: Josh Dekker <josh@itanimul.li>	4 years ago
Reimar Döffinger	30f80d855b	lavc/aarch64: port HEVC SIMD idct NEON Makes SIMD-optimized 8x8 and 16x16 idcts for 8 and 10 bit depth available on aarch64. For a UHD HDR (10 bit) sample video these were consuming the most time and this optimization reduced overall decode time from 19.4s to 16.4s, approximately 15% speedup. Test sample was the first 300 frames of "LG 4K HDR Demo - New York.ts", running on Apple M1. Signed-off-by: Josh Dekker <josh@itanimul.li>	4 years ago

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

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

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
