On other SoCs i’m testing it gives expected results: diagonal colored stripes. There is single exception: rk356x with vop2 - where screen is green unless i „fix/enable” by playing with plane #69 > I did with "modetest -s 69@67:1920x1080 -d" and with this it works as > expected, I can't reproduce any green screen issue here. I see you are using plane #69. Why not #43? Is plane #43 working ok for you? I’m using plane #43 because: application (player) - at start - queries all planes and selects first plane offering format being within offered formats by provider (video decoder; NV12 from rk356x hantro video decoder). pls look on app log regarding planes discovery and election: https://pastebin.com/edAhbcvU Now - looking what VOP2 reports: https://pastebin.com/8ujkaV9n is see first plane accepting NV12 is #43 - so my app is electing this plane to use for displaying video. This strategy works well for all 13 platforms i’m supporting (only 13 i have in my testbed). If this approach is - by Yours VOP2 patches goal - is not supported - then OK. I understand this :-) But - if You want to support DRM features in the same way like other SOC are doing (and working well with KODI/MythTV/mpv/etc) - then i think: 1\ DRM plane #43 not supports NV12 - but code wrongly reports NV12 format is supported, or 2\ DRM plane #43 is supported - but code has bug resulting with green screen.
