I want to take a few RTSP cameras and put them into a mosaic, that I can then read from Home Assistant. So I was trying to set them up with rtp, have also tried multicast based on the wiki:
https://wiki.videolan.org/VLC_HowTo/Make_a_mosaic/
With rtp I managed for a while to get a display, but it was broken up, as though it was only showing the changes and never the key frames, just little squares of data. But correct data, in a mosaic.
With multicast I cannot get anything to happen, and wireshark captures show no data transmitted (>=224.0.0.0).
I have no problem playing the cameras using VLC, i.e. authentication and reachability is fine. There's also no performance issue, plus the frame rate from the cameras is only 4fps (but at 4k). I have the firewalls off on both computers for now just to ensure it is not the issue.
With rtp and reading via rtsp besides the broken video examples, I also mostly get a "access_realrtsp warning: only real/helix rtsp servers supported for now" when i try to play the mosaic via VLC, and nothing I've found online helped. Somewhere along the line of experimenting that crept in.
Telnet shows state of the background and channels says "playing". The logs show a ton of "mosaic debug: too late for picture" errors, which would at least seem to indicate it is trying.
This is what I've tried most recently, lifted more or less verbatim from the wiki example, except with different input.

Can someone give me a pointer? And a for-sure working example of producing an output I can read with rtsp?
