I'm still getting loss of a/v sync in my el7 box, more noticeable in 
some recordings than others, but the fedora 30 system built at the same 
commit has not yet done the same, using either NVdec or ffmpeg decoding.

The OSD of playback data doesn't show any drift in the a/v sync value, 
even when an offset of over 1 s has developed.
