video error

### Steps to reproduce

I configured the self-deployed jitis video service and applied config.json on the desktop client,
but after starting the call, I added rooms to different accounts on multiple devices to test.
Only the voice was normal, while the video and screen were not transmitted,
which was present in the element scene (beta version video room, Widget Windows, pop-up web pages).
I tried calling again on the self-deployed jitis web page and everything worked.
What happened? What should I do?
