I was trying to do some test and found that the installed HDR10 working app isn't able to keep audio and video in sync (while the file plays fine on my PC).
There are various walkaround, like using SD player that cut off the HDR10 structure (making the whole thing a lot less BORING to watch) but both the embedded player and MX Player (the other one that has Rockchip HW and HDR support) have the same problem, so it's probably linked to a driver / hardware bug somewhere.
Anyone knows what to do to fix the issue ?
