Own video is black. After changing the view, own video is shown

I have a problem with displaying my own camera video in the web app.

When I start the meeting, my own video is just black with my name in it.
When I change the view from speakeer view to grid view or vice versa, the camera view is “activated” and I can see myself.

Other participants of the meeting can see me all the time, even when my own video is shown black at my web app.

Which Web Client SDK version?

To Reproduce(If applicable)
Steps to reproduce the behavior:


Device (please complete the following information):

  • Device: PC
  • OS: Win 10
  • Browser: Chrome
  • Browser Version 90.0.4430.85

Hi, @MZL,

Thank you for posting in the Developer Forum–happy to help! Do you see any errors in the browser console? If so, can you share a screenshot of the error that is shown ?

Looking forward to your response.


I´m getting two errors. But these errors occur before I start the camera.

Don´t mind the first screenshot with the broken CSS.
I fixed the error:

But still the same error on multiple different devices with Chrome.
In Firefox, there is no problem.
