[AVCaptureSession startRunning] startRunning crash

[badarovska]

Sometimes when publishing a stream, I am getting the following error:

[AVCaptureSession startRunning] startRunning may not be called between calls to beginConfiguration and commitConfiguration

I have not found specific steps to reproduce it. It is not often, but it is happening on my production app as well. In the live app I am using Opentok 2.24.1, but I upgraded to 2.24.2 locally and the issue remains.

• iOS SDK version: Opentok 2.24.1, Opentok 2.24.2
• OS and version: iOS 14, iOS 15, iOS 16

Thanks, @badarovska, for letting us know about this issue.

We've been able to reproduce. We're working on a fix now: https://jira.vonage.com/browse/VIDCS-13.

Just wanted to share another update. We hope this will be fixed in the upcoming 2.25.0 release.
