On a Pi 4 8GB running the latest version of Raspbian. GPU memory is at 512MB. I am attempting to run two instances of omxplayer with the following commands:

/usr/bin/omxplayer.bin --avdict rtsp_transport:tcp --win "515 5 1212 472" --live --no-osd --layer 0 --fps 10 -n -1 rtsp://user:[email protected]/live --dbus_name org.mpris.MediaPlayer2.omxplayer0

/usr/bin/omxplayer.bin --avdict rtsp_transport:tcp --win "1218 5 1915 472" --live --no-osd --layer 1 --fps 10 -n -1 rtsp://user:[email protected]/live --dbus_name org.mpris.MediaPlayer2.omxplayer1

When this happens, my screen continually flashes black, as if the HDMI is losing signal. But if I stack the second stream with:

/usr/bin/omxplayer.bin --avdict rtsp_transport:tcp --win "515 478 1212 955" --live --no-osd --layer 1 --fps 10 -n -1 rtsp://user:[email protected]/live --dbus_name org.mpris.MediaPlayer2.omxplayer1

The streams play just fine. I am out of ideas at this point.

I have added the -g flag to the second stream, and here is the log dump:

The display is composited in real time. The display scans out from top to bottom.
When videos are vertically stacked you only have to fetch one image per output line.
When videos are horizontally stacked you have to fetch both images per output line.

The latter case is roughly twice as hard. When composition fails to keep up you get display blanking out.

You can try adding dispmanx_offline=1 to config.txt which may help the blanking as we composite to an offscreen buffer which is then subsequently displayed, but it will harm overall framerate.

Thanks for looking into this. The dispmanx_offline=1 addition did not work. Interestingly, the streams work if they are catacorner, but if they overlap at all, the blanking issue returns.

I may try this with a fresh raspbian install to see what happens.

Is the issue fixed?
I got the same issue.

work (Assume it runs first)
omxplayer -n -1 --win "0 0 949 529" -r --aspect-mode Letterbox -b --live rtsp://user:pass@ip_1:port/onvif1
does not work
omxplayer -n -1 --win "950 0 1900 530" -r --aspect-mode Letterbox -b --live rtsp://user:pass@ip_2:port/onvif1

it only works if:
(1) when playing a video
omxplayer -n -1 --win "950 0 1900 530" -r --aspect-mode Letterbox video.mkv
(2) when playing a stream vertically
omxplayer -n -1 --win "0 530 949 1059" -r --aspect-mode Letterbox -b --live rtsp://user:pass@ip_2:port/onvif1
