I use this box since several months now and I like it very much.
In particular the AV1 hardware decoding is where I was focused on. Before I used a Odroid N2, which wasnt able to do that.
Now I discovered that sometimes there is problem in playback 4K HDR10 AV1 (SVT) encoded videos. When there is complete black scene, it sometimes stay with this, meaning the screen remains black although the video should show something.
I was able to contain the problem. Those problematic videos where encoded with tile rows = 0 and tile columns = 0.
When I encode with tile rows and tile columns >= 2, everything works fine.
I observed it on the latest 21.1.1.
Does someone discovered the same issue?
