[FFmpeg-devel] [PATCH v2 2/9] avcodec: add D3D12VA hardware accelerated H264 decoding
Tong Wu
tong1.wu at intel.com
Wed May 31 06:07:15 EEST 2023
From: Wu Jianhua <toqsxw at outlook.com>
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
