[Question]: FFMPEG AV1 input = limited GPU processing without copying in Windows?

[pbaykalov]

-hwaccel amf has no interop with OpenCL: https://trac.ffmpeg.org/wiki/Hardware/AMF
-hwaccel d3d11va has no interop with OpenCL: https://trac.ffmpeg.org/wiki/HWAccelIntro#OpenCL
AV1 decoding with DXVA2 is not supported: https://trac.ffmpeg.org/wiki/HWAccelIntro#Decoding

Therefore, there are no efficient ways of processing AV1 on GPU except hwdownload,hwupload?
