SOLVED: Codec issues - Hardware Accelaration

[TheDreadPirate]

For the record, 4:2:0 is not the same as 10-bit HEVC. 4:2:0 is the chroma subsampling which is separate from bit depth. The 1070 supports 10-bit HEVC (I have one).

The log you provided doesn't have enough info and you also did not provide the symptom and circumstances. I don't see transcoding, or much of anything. Usually when playback happens there is more info that what was provided in your log.

Is that the whole thing? Were there any ffmpeg logs? From what was provided it looked like it direct played (no transcoding).
