When trying to start playing several of my recent AV1 encoded videos, the Ugoos AM8 Pro crashes. If I disable AV1 hardware decoding, no problems.

Another issue with AV1 HW decoding is the HBO logo with heavy static noise. When starting playback, the screen stays black and audio continues normally. Then after a long time, video playback resumes. Video playback sometimes also starts to work when jumping back 10 seconds or so.

One thing I noticed while testing this: when the playback starts and screen stays black, the ‘O’ menu shows 1280x720p video. If I jump back and video playback resumes, 1280x720i is what it shows. My clips are progressive so I don’t know where it gets the ‘i’ there.
Disabling hardware decoding also fixes this issue (and libdav1d shows 1280x720p).
