Hi Dmitry, How about this: -init_hw_device qsv=vad:hw_any,child_device=/dev/dri/renderD128 Unfortunately I do not have one of the new Intel discrete GPUs so I wasn't able to test, but the above parameter is working at least in a way that it fails when the specified child_device is wrong (e.g. Nvidia GPU)). Kind regards, softworkz _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-devel To unsubscribe, visit link above, or email ffmpeg-devel-requ...@ffmpeg.org with subject "unsubscribe".
