[FFmpeg-user] Filter lut3d with GPU Accelaration?

[Rainer Fritz]

Dear All !

Thx for such a great tool ffmpeg is. I use the lut3d filter often and getting currently
on a MacbbokPro i7 about 12fps when transcoding from Prores4444 to DNxHD for example.

Is there a possibility to accelarate this filter by the GPU (openCL or openGL)? How much work will it be to implement
this? Who can be contacted regarding this?

THX
