I tested 4k@60 (YUV420 not HDR, "bbb-3840x2160-cfg02.mkv") with mpi_dec test. HDR ("LG Chess 4K Demo.mp4") and HLG ("LG Cymatic Jazz 4K Demo.ts") test are decoded ~60FPS but output only with 4k@30 output (forced in extlinux.conf) to LG TV OLED without problem. Check actual output chain with:
Code:
# cat /sys/kernel/debug/dw-hdmi/status
# cat /sys/kernel/debug/dri/0/summary
I left this community in Aug 2019 due to PINE64 refusal to produce/deliver ROCK64-1G version 3 after more than one year of changing statuses to "planning", "evaluating", "releasing", "availability", "estimated availability" and finally "no schedule" . ROCK64 is dead platform without any advantage. Buy Raspberry PI 4 !
