I have run this on my box but I'm dissapointed because I get better 1080P youtube with mainline kernel. I think the problem is that this repo is focused in rk3588 with uses mali driver with GBM, and seems that panfrost has not it. I can run 4K video with poor results and that means MPP is enabled (checked with dmesg). I have better video with vendor android.
Don't waste your time, I will do it for you O:)
