Sascha,

FYI:
I was hoping v9 will fix green screen issue i see when video player wants to 
draw to nv12 capable drm plane.
It look issue is still present :-(

You can easily reproduce with modetest utility:

modetest -P 43@67:1920x1080@NV12 

gives green screen.

however if you do:

modetest #43 (green screen)
modetest #49  (ok)

then

modetest #43 

gives expected result ("rainbow" picture on screen)

let me know if i can do any extra tests helping you to fix issue
