Thank you for working on NV12 plane support. ChromeOS eagerly wants this feature to save power on Youtube. If it's landed soon, I'll really appreciate it.
Kristian is working on backporting it to the downstream ChromeOS kernel.
I tested it on my Apollo Lake chromebook, but there is blackscreen flickering. NOTE: RGBA, RGBX, BGRA, BGRX, YUYV works without flickering.
Best regards,
DS

shouldn't matter too much, as long as no one has based any userspace tests
on these since later versions will change how interpret fb->offsets[].
