Lynne	9f9534f5b6	vulkan_decode: fix typo when setting AV1 capabilities All pNext chained structs in Vulkan are defined as void *, so it doesn't help catch this.	1 year ago
Dawid Kozinski	637afea88e	avcodec: MPEG-5 EVC codec registration Added prerequisites that must be met before providing support for the MPEG-5 EVC codec - Added new entry to codec IDs list - Added new entry to the codec descriptor list - Bumped libavcodec minor version - Added profiles for EVC codec Signed-off-by: Dawid Kozinski <d.kozinski@samsung.com> Signed-off-by: James Almer <jamrial@gmail.com>	1 year ago
Lynne	e71cd18049	vulkan_decode: do not align the image dimensions According to Dave Airlie: > <airlied> but I think ignoring it should be fine, I can't see any > other way to get the imaeg extents correct for other usage > <Lynne> what width/height should be used for the images? > the final presentable dimensions, or the coded dimensions? > <airlied> if you don't want noise I think the presentable dims > <airlied> the driver should round up the allocations internally, > but if you are going to sample from the images then w/h have to be > the bounds of the image you want > <airlied> since otherwise there's no way to stop the sampler from > going outside the edges Apparently, the alignment values are informative, rather than mandatory, but the spec's wording makes it sound as if they're mandatory.	1 year ago

James Almer	fe103ee61f	avcodec/vulkan_dec: use PRId64 specifier for an int64_t Fixes warnings on x86-32 and Windows. Signed-off-by: James Almer <jamrial@gmail.com>	1 year ago
Lynne	bae92361ed	vulkan_decode: check if yuv_sampler exists before freeing it This prevents multiple NULL accesses - if yuv_sampler exists, then everything required for it to be destroyed also exists.	1 year ago
Lynne	58f82fc26a	vulkan: replace usage of %lu with %"SIZE_SPECIFIER"	1 year ago
Michael Niedermayer	988fd5743d	avcodec/kbdwin: Remove low precision intermediate in ff_kbd_window_init_fixed() Previously floats where scaled up to 32bit int, but floats do not have 32bits in their mantisse so a quarter of the bits where nonsense. It seems no fate test is affected by this change, which is interresting Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	1 year ago

Lynne	f3795e1857	APIchanges: add AVHWAccel changes and bump lavc minor	1 year ago
Lynne	f701f088f4	vulkan_h264: reject end_frame being called without valid session parameters When seeking through MBAFF-coded H264, this can happen. Decoding calls end_frame without calling start_frame. We are unable to decode this, as no frame state has been set. Happens for both VAAPI and Vulkan. Could be an issue elsewhere, hence the individual commit.	1 year ago

Dave Airlie	e49b8b48cd	av1: set skip mode frames properly There are circumstances where the flag isn't set but the skip mode frames are. So don't use the inferred bit which has other inputs when deciding to pass the skip mode frames to the device. This fixes some decoding bugs on intel av1	1 year ago

Lynne	20de09a6de	h264_ps: expose scaling_matrix_present_mask Vulkan requires it. It technically also requires use_default_scaling_matrix_mask, but we can just be explicit and give it the matrix we fill in as-non default.	1 year ago

Anton Khirnov	a4611e3170	lavc/decode: pass AVHWAccel instead of AVCodecHWConfigInternal to hwaccel_init() The only thing besides the hwaccel that this function uses from AVCodecHWConfigInternal is the pixel format, which should always match the hwaccel one. Will be useful in following commits.	1 year ago
