Okay. The Color-Blank-Screen is solved for now. The new strange behaivour is like the video below. omx or the whole pi crashed at opening all rtsp streams.

I simply run this script below to show 4 Cams as RTSP on RPi4B 8GB

#!/bin/sh

#4ER VIEW
screen -dmS left_top sh -c 'omxplayer --win "0 0 960 540" -b --live rtsp://user:pass@127.0.0.1:554/stream0/mobotix.mjpeg -n -1'
screen -dmS right_bot sh -c 'omxplayer --win "960 540 1920 1080" -b --live rtsp://user:pass@127.0.0.1:554/stream0/mobotix.mjpeg -n -1'

I've uploaded to a temp plattform streamable: https://streamable.com/sffgu9

After pkill "omx" the display comes back to the normal desktop.

This are the log results for WARNING only. I have no entries for "ERROR".

Absolutley Strange. The last 5 Kernel Version have the same problem. Now, after I upgrade to the latest version; I have the problem from #777 again and no more the problem from #779 (this case).

Any Ideas @popcornmix ?

Now, in a fresh installed RaspberryPi OS image I had the same problem as from the video (https://streamable.com/sffgu9). The only thing what I've changed was

  1. ip address from system
  2. memory-split to 256MB
