Tong Wu	0faf2ca98a	avcodec/d3d12va_decode: remove extra spaces for declaration Signed-off-by: Tong Wu <tong1.wu@intel.com>	9 months ago
Andreas Rheinhardt	790f793844	avutil/common: Don't auto-include mem.h There are lots of files that don't need it: The number of object files that actually need it went down from 2011 to 884 here. Keep it for external users in order to not cause breakages. Also improve the other headers a bit while just at it. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>	9 months ago
Tong Wu	92ee7461c3	avcodec/d3d12va_decode: fix different 'const' qualifiers warning Signed-off-by: Tong Wu <tong1.wu@intel.com>	11 months ago
Mark Thompson	fa580a0f17	lavc/d3d12va: Improve behaviour on missing decoder support Distinguish between a decoder being entirely missing and a decoder which requires features which are not present in the incomplete implementation in libavcodec and therefore can't be used.	11 months ago
Tong Wu	8b41e9cfbe	avcodec/d3d12va_decode: check existance before assigning a new index Fixes #10759. It can happen in H.264, MPEG2, VC1 that the current frame resource memory is already in ref_resource. For example, for a interlaced frame, the same curr memory is passed twice. For the second time it could possibly reference itself. When this happens the curr is already given an index and in ref_resources. When the reference frame index is required, we should check the existance in the ref_resources first before assigning a new index for it. Signed-off-by: Tong Wu <tong1.wu@intel.com>	11 months ago

Wu Jianhua	94949d4770	avcodec/d3d12va_decode: don't change the resource state if the referenced frame is the same as the current frame This commit removes the follow warning and error: D3D12 WARNING: ID3D12CommandList::ResourceBarrier: Called on the same subresource(s) of Resource(0x000002236E0E00D0:'Unnamed ID3D12Resource Object') in separate Barrier Descs which is inefficient and likely unintentional.

Tong Wu	0f01581ccd	avcodec/d3d12va_decode\|dxva2: add a warning to replace assertion Previous assertion was not useful. Now a warning is added to replace it. For get_surface_index, we should return a zero index in case the index is not found. But a warning is necessary to notify. Signed-off-by: Tong Wu <tong1.wu@intel.com>	12 months ago

Martin Storsjö	327685bafe	d3d12va: Add a missing include for the declaration of ff_d3d12va_get_surface_index This fixes the following build error: src/libavcodec/d3d12va_decode.c:49:10: error: no previous prototype for function 'ff_d3d12va_get_surface_index' [-Werror,-Wmissing-prototypes] 49 \| unsigned ff_d3d12va_get_surface_index(const AVCodecContext *avctx, \| ^ Signed-off-by: Martin Storsjö <martin@martin.st>	1 year ago
Wu Jianhua	349ce30e4e	avcodec: add D3D12VA hardware accelerated H264 decoding The implementation is based on: https://learn.microsoft.com/en-us/windows/win32/medfound/direct3d-12-video-overview With the Direct3D 12 video decoding support, we can render or process the decoded images by the pixel shaders or compute shaders directly without the extra copy overhead, which is beneficial especially if you are trying to render or post-process a 4K or 8K video. The command below is how to enable d3d12va: ffmpeg -hwaccel d3d12va -i input.mp4 output.mp4 Signed-off-by: Wu Jianhua <toqsxw@outlook.com> Signed-off-by: Tong Wu <tong1.wu@intel.com>	1 year ago
