* avcodec/d3d12va_decode: enable reference-only modeAraz Iusubov2025-04-051-12/+152
| | | | | | | | | | | | | The Reference-Only feature in DirectX 12 is a memory optimization technique designed for video decoding scenarios. This feature requires that reference resources must be allocated with the D3D12_RESOURCE_FLAG_VIDEO_DECODE_REFERENCE_ONLY resource flag. Reference textures must also be separated from output textures. This feature is not supported in the current version of ffmpeg. Since AMD GPU uses this feature in Direct 12 decoder, ffmpeg does not support AMD GPU Direct 12 decoding. Signed-off-by: Tong Wu <wutong1208@outlook.com>

* avutil/common: Don't auto-include mem.hAndreas Rheinhardt2024-03-311-0/+1
| | | | | | | | | | | 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>

* lavc/d3d12va: Improve behaviour on missing decoder supportMark Thompson2024-02-041-4/+8
| | | | | | 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.
* avcodec/d3d12va_decode: check existance before assigning a new indexTong Wu2024-01-261-7/+7
| | | | | | | | | | | | | 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>

* avcodec/d3d12va_decode|dxva2: add a warning to replace assertionTong Wu2024-01-051-2/+1
| | | | | | | | 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>

* avcodec: add D3D12VA hardware accelerated H264 decodingWu Jianhua2023-12-211-0/+538
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>
