The release is only proven out for HEVC 4K with lossless (PCM or bitstream) audio, plenty wrong with other formats and not in plans to fix, sharing as many people asked.
There are now also other great build out there covering more formats and SoC (players)
Only test with my cpm.Estuary skin, other could be broken including builtin.
Many contributors to this, see repo, will post up more details later.
