 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:
 https://trac.ffmpeg.org/wiki/Hardware/QuickSync

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