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Anton Khirnov	5cc0057f49	lavu: remove the custom atomic API It has been replaced by C11 stdatomic.h and is now unused.	8 years ago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	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

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
Diego Biurrun	a339e919ca	ea: Change type of array stride parameters to ptrdiff_t ptrdiff_t is the correct type for array strides and similar.	8 years ago
Diego Biurrun	ba479f3daa	hevc: Change type of array stride parameters to ptrdiff_t ptrdiff_t is the correct type for array strides and similar.	8 years ago
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

Diego Biurrun	b2939a7527	blockdsp: Change type of array stride parameters to ptrdiff_t ptrdiff_t is the correct type for array strides and similar.	8 years ago
Diego Biurrun	3281d823cd	intrax8: Change type of array stride parameters to ptrdiff_t ptrdiff_t is the correct type for array strides and similar. Also rename all such parameters to "stride" for consistency.	8 years ago
Diego Biurrun	92c5755a18	hpeldsp: arm: Update comments left behind in `25841dfe80`	8 years ago
Diego Biurrun	009adfd4fb	x86: fpel: Remove unnecessary sign extend	8 years ago
Mark Thompson	956a54129d	vaapi_h264: Set max_num_ref_frames to 1 when not using B frames	8 years ago
Mark Thompson	086e4b58b5	vaapi_encode: Sync to input surface rather than output While outwardly bizarre, this change makes the behaviour consistent with other VAAPI encoders which sync to the encode /input/ picture in order to wait for /output/ from the encoder. It is not harmful on i965 (because synchronisation already happens in vaRenderPicture(), so it has no effect there), and it allows the encoder to work on mesa/gallium which assumes this behaviour.	8 years ago
Mark Thompson	892bbbcdc1	vaapi_encode: Check packed header capabilities This improves behaviour with drivers which do not support packed headers, such as AMD VCE on mesa/gallium.	8 years ago
Mark Thompson	80a5d05108	vaapi_encode: Refactor initialisation This allows better checking of capabilities and will make it easier to add more functionality later. It also commonises some duplicated code around rate control setup and adds more comments explaining the internals.	8 years ago
Anton Khirnov	67d28f4a0f	examples/output: switch to the new encoding API	8 years ago
