Dolby Vision for Minix U22X-J (Max) and Ugoos AM6+

Anyone want to try this build?
Really hope this is the ticket. Ideally you want refresh rate switching on start/stop, and 1920x1080 60hz (this allows HDR10+ to run for me!). cs/cd set to auto. Either LLDV or TV-led–your pick.

Some things I noticed:

  • When I play Dune, I no longer get any skipped frames. Not setting wait delay either (set to default of 2). Not sure if this is incorporating cpm’s new MEL detection, but I want to say probably not? But not sure… My prior fix attempt would switch to 12-bit then back to 8-bit. This new build doesn’t seem to do that.
  • Specifically LLDV on Dune no longer starts with distorted colors.
  • It also will not force your display to 4k @ 4:2:0 8-bit and should rely instead more on your TV’s EDID. I suspect this behavior was exacerbating the race condition present in the mode setting.
  • Hitting fullscreen no longer blanks out the screen (previously seemed to resemble refresh rate switch). Likely related to the previous issue.
  • Fixes, the 8-bit 4:4:4 4K @ 60hz that got set, which is problematic for HDR10. It’s now setting to 4:2:2 12-bit at 4K @ 60hz (specifically fractional).

Hope to eventually switch to CE 21 to try this, but for some reason FEL titles stall out on resume, and kills the playback on skipping chapters. So sticking with CE 20 for that stability while I try to iron out the bitrate setting issues.

Edited slight tweak, current with pull 36:
