Clément Bœsch	a692724c58	vp9lpf/x86: add x86 SSSE3/AVX SIMD for vp9_loop_filter_[vh]_16_16. Signed-off-by: Anton Khirnov <anton@khirnov.net>	8 years ago
Ronald S. Bultje	c935b54bd6	checkasm: add VP9 loopfilter tests. The randomize_buffer() implementation assures that "most of the time", we'll do a good mix of wide16/wide8/hev/regular/no filters for complete code coverage. However, this is not mathematically assured because that would make the code either much more complex, or much less random. Some fixes and improvements by Rodger Combs <rodger.combs@gmail.com> Signed-off-by: Anton Khirnov <anton@khirnov.net>	8 years ago
Ronald S. Bultje	a451324ddd	vp9: ignore reference segmentation map if error_resilience flag is set. Fixes ffvp9_fails_where_libvpx.succeeds.webm. Bug-Id: ffmpeg/3849. Signed-off-by: Anton Khirnov <anton@khirnov.net>	8 years ago

Vittorio Giovara	497c087939	avidec: Set palette alpha as fully opaque Palette format is always in RGBA.	8 years ago
Vittorio Giovara	bad4aad403	avidec: Do not special case palette on big-endian This simplifies the code a bit, does not change output data in any way.	8 years ago
Vittorio Giovara	310c55f179	pixfmt: Document alternative names for smpte 431 and 432	8 years ago
Mark Thompson	5a5df90d9c	vaapi_h265: Add main 10 encode support	8 years ago
Mark Thompson	eaaaabf6c9	hwcontext_vaapi: Enable P010 support This is required for 10-bit surfaces.	8 years ago
Mark Thompson	b8cac1e830	vaapi_h265: Fix buffering parameters A decoder may need this to be set correctly to output frames in the right order.	8 years ago
Mark Thompson	fc30a90898	vaapi_h265: Fix slice header writing This was not observed earlier because the only syntax element which it normally misses with the current setup is slice_qp_delta, but that is always going to be zero (in IDR frames QP isn't varied on the slice) which will always exp-golomb code as a single 1 bit. The immediately following part is the byte alignment, which is always a 1 bit followed by 0s which are ignored, so as long as the bitstream is never aligned at that point we will never notice because the only difference is that an ignored bit is a 1 instead of a 0.	8 years ago
Mark Thompson	ec17ab381e	vaapi_h264: Write bitstream restriction fields	8 years ago
Mark Thompson	17a0f9481c	vaapi_h264: Fix CFR mode with frame_rate set in AVCodecContext	8 years ago
Mark Thompson	314b421dd8	vaapi_encode: Decide on GOP setup before initialising sequence parameters This was always too late; several fields related to it have been incorrectly zero since the encoder was added.	8 years ago
Anton Khirnov	5cc0057f49	lavu: remove the custom atomic API It has been replaced by C11 stdatomic.h and is now unused.	8 years ago

Anton Khirnov	64a31b2854	pthread_frame: use atomics for PerThreadContext.state	8 years ago
Anton Khirnov	db2733256d	pthread_frame: use a thread-safe way for signalling threads to die Current code uses a plain int in a racy way, which is UB.	8 years ago
Anton Khirnov	8385ba53f1	mmaldec: convert to stdatomic	8 years ago
Anton Khirnov	3a165c187d	v4l2: convert to stdatomic	8 years ago
Anton Khirnov	27079a426c	buffer: convert to stdatomic	8 years ago

Anton Khirnov	13f5d2bf75	configure: check for stdatomic.h Since this is a C11 feature, it requires -std=c11. Not actually used for anything yet, that will be added in the following commits.	8 years ago
Luca Barbato	b015872c0d	huffyuvdsp: Enable the altivec code for PPC little-endian as well Confirmed to work by checkasm.	8 years ago
Luca Barbato	1d25a86902	huffyuvdsp: Reenable PPC optimizations	8 years ago
Alexandra Hájková	22c3ab1864	checkasm: Add test for huffyuvdsp add_bytes Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	8 years ago
Anton Khirnov	27085d1b47	avconv: only retry decoding on actual decoding errors Errors during decoding are currently considered non-fatal and do not terminate transcoding, so even if parts of the data are corrupted, the rest may be decodable. However, that should apply only to the actual decoding calls, not to the failures elsewhere (e.g. configuring filters).	8 years ago
Anton Khirnov	f6772e9bf8	avconv: make sure the filtergraph is freed on init failure The filtergraph's existence is used in several places to mean that the filtergraph is fully configured. This causes problems if it's allocated, but the initialization fails (e.g. if a non-existent filter is specified).	8 years ago
Anton Khirnov	d10102d23c	avconv: set the encoding framerate when the output is CFR	8 years ago
Anton Khirnov	5bf2454e7c	h264dec: support broken files with mp4 extradata/annex b data Bug-Id: 966	8 years ago
Anton Khirnov	2124711b95	hwcontext_vaapi: add a quirk for the missing MemoryType attribute The Intel binary iHD driver does not support the VASurfaceAttribMemoryType, so surface allocation will fail when using it.	8 years ago
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	a9ba59591e	ac3dsp: Add some special-case handling for the C downmix function This is about 200% faster for in-decoder downmixing of 5.0 and 5.1 content. 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
Anton Khirnov	8ea35af762	avio: add a new flag for marking streams seekable by timestamp	8 years ago
Anton Khirnov	75c1db6152	avio: cosmetics, prettify AVIO_SEEKABLE_NORMAL Move the doxy above the definition, change the value itself to the (1 << n) pattern, which is more readable for flags.	8 years ago
Anton Khirnov	83548fe894	lavf: fix usage of AVIOContext.seekable It is supposed to be a flag. The only currently defined value is AVIO_SEEKABLE_NORMAL, but other ones may be added in the future. However all the current lavf code treats this field as a bool (mainly for historical reasons). Change all those cases to properly check for AVIO_SEEKABLE_NORMAL.	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	15b4f494fc	mss*: Change type of array stride parameters to ptrdiff_t ptrdiff_t is the correct type for array strides and similar.	8 years ago
