Notes
Since the AMD AMF decoder has not yet been implemented in FFmpeg, we have used the D3D11VA decoder as an alternative. But this will bring greater performance loss compared to NVDEC/NVENC.
It is recommended to use a multi-core CPU and a discrete graphics card for better performance. And turn off AMF hardware decoding during tonemapping.
If you want to promote the implementation of AMD AMF decoder in FFmpeg, please let their staff know at the link below.
