Errors finding drm plane with fitting format. rk3588

[Fredrum]

Hello!

I'm trying to render decoded video frames to screen using drm planes under tty. (no x11, no GL)
I got an accepted crtc.
The frames are getting decoded with hevc_rkmpp.
But when I try to render them I get errors when trying to match the AV_PIX_FMT_DRM_PRIME or DRM_FORMAT_NV12 frames with the planes from drmModeGetPlane(); (using #include <xf86drm.h>)

How can I get a good plane-to-format matchup to do drm render straight to screen?

I am using Armbian and,

Cheers!
