ffmpeg: can't select device on multi gpu systems #39

Closed dvrogozh closed 4 years ago

dvrogozh commented 4 years ago

Current way for device selection (w/ -hwaccel qsv -hwaccel_device ) does not actually works. See https://github.com/Intel-Media-SDK/MediaSDK/wiki/FFmpeg-QSV-Multi-GPU-Selection-on-Linux for proper device selection break down.

Fix for measure-perf is in #36.
