chewitt The constructions made by your github repository are better.
LibreELEC-AMLGX.arm-9.80.9-box constructions.
I tried the constructions of LibreELEC master amlogic: I have problems with synchronization between audio and video, locks on the kodi when changing channels, small tremors on the screen in HD reeds.
SD channels do not open anything, neither image nor audio, sometimes a green screen.
On the other hand I used your constructions from your amlogic github: Synchronization between audio and video works well, small shakes on the screen in HD reeds.
SD channels only receive green screen but receive audio. Even the blue screen with audio.
I have no locks on the kodi, sometimes the channel change takes a while.
Tests were done using the tbs5520se on both patched constructions.
I also did tests with streaming and got the same results.
I noticed that both constructions have different mesa versions.
