RK3399 support?

[goraj]

Hi,

Thank you for your work!
Any chance you’d consider to add RK3399 support in the future?

Cheers

Which rk3399 board?

I've the nanopi m4v2. I'm especially curious if RKMPP would work for hardware en/decoding. (To use with jellyfin). I'm on armbian and can make some devices show up, but it's not working.

The status of where im at:

ls -l /dev | grep -E "mpp|rga|dri|dma_heap"
drwxr-xr-x 2 root root          80 Jan  1  1970 dma_heap
drwxr-xr-x 3 root root         120 May  5 00:55 dri
crw-rw---- 1 root video   241,   0 May  5 00:55 mpp_service
crw-rw---- 1 root video    10, 122 May  5 00:55 rga

device /dev/mali0 doesn't show up, idk if that matters.
