OpenTok Video Call Issue when application goes from background state to foreground

Question

I have done video calling using OpenTok (Tokbox Sample for video calling among multiple users). I am facing a random issue in my application when my application enters in background mode and again application is sent to foreground.

Session remains connected but the video will not be displayed to other users(Black screen is displayed).

I have enabled publishvideo in publisher and subscribe to video for currentsubscriber. _publisher.publishVideo = YES; _currentSubscriber.subscribeToVideo = YES; Is there any way to fix this issue.

Any help is appreciable.
