Replying to [comment:4 eero-t]:
> Specifying qsv_device makes it work, as does unsetting $DISPLAY.
>
> As I need to specify device already for VA-API to work, it's fine for me
to do that also for QSV.
So, is it ok to close this ticket now?
> Before fixing the render node selection in code, please document
"qsv_device" usage (for multi-card use-cases) in FFmpeg QSV examples:

Good suggestion, will add it later. Thanks for remind.
