Hi, I’m using OpenVidu Ionic. And I’ve found out that the frameRate was set to 30 on the initPublisher function.

Is there a way to make it dynamic in such a way that the screen will be shared based on the number of participants?

At the moment, it left the screen blank when it one or fewer people connected.

Thank you for the wonderful job you’re doing here.

AFAIK you only can change bandwidth dynamically
