[Cin] QSV profile debuggin thread

So, Terje, can you run your usual working ffmpeg command encoding av1 via system fmmpeg/qsv but with added -loglevel debug ? and post full output here. Then we can set same loglevel in bin/ffmpeg/encode.opts so we hopefully will spot difference in parameters send down to line ... then we can try to make ffmpeg fail by adding say -profile=main to ffmpeg's command line and see more detailed error then hopefully we can tweak qsv_av1 profile back into usability. Repeat for vp9/h264.
