Hey @itramkumar.78

Thanks for using the dev forum!

Sometimes, the state of the meeting can update the video streams and the video stream can become interrupted.

Can you provide the code of setting up your preview video? Usually when this issue occurs, the preview setup code just needs to be moved to another spot in the code.

Thanks!
Michael
