Encoding Discussion Megathread (ffmpeg, Handbrake, AV1, etc...)

[bitmap]

This is somewhat helpful for a number of reasons, but I tried several iterations and was unsuccessful. I'm not sure I fully understand the syntax of the filter_complex (as I always get an error there if I'm not doing something like in the snippet you provided: overlaying subs). I tried a regular filter with deriving the ocl device, then ending with hwmap for qsv and that didn't work. Added format, no dice. Even tried vpp_qsv to set the format.

I guess I'm not wrapping my head around the ffmpeg side of things...I want to QSV decode --> OpenCL filter --> QSV encode. Seems like it should be possible, but I dunno. Not interested in chasing ghosts, though...
