you can try to add deinterlacing filter in cingg? Do not forgot to set

so, h264/5 qsv in cingg works, but vp9/av1 not?

I'll add two more silly patches as attachment, they hopefully correct
hevc/h264 profiles and add remark about how they only usable with ext.
ffmpeg (for now).

Sorry about such extended debugging. Thanks for patience (over the years!)

you probably can play with p010 and profile=main10 for 10-bit encode but I
am not sure if it will work.
