I'm trying to have omxplayer displaying a video on a
display_rotate=1 screen, on a 3b+ with raspbian .
I was using the omxplayer node from nodered, but the problem is here with commandline omxplayer.
When the screen is not rotated, the mp4 plays perfectly with the audio, it also plays fine with
--orientation 90, but with
display_rotate=1, it gives me a green screen flickering, with audio playing.
I suspected it was this problem, but since the
--orientation 90 option works fine it feels different.
the screen is a standard desktop one, apt-get is upgraded & updated.
