Issue seen after improvemnt work with framerate and resolution for publisher. earlier it was working fine but video quality was not good

[ManojCommscope]

look like calling of camera from different thread

[ManojCommscope]

look like got the root cause.

the very first time there is no exception showing in log.

but once we end the call and start the call again we see this exception.

From OpenTok not closing the camera or not closing properly when we end the call and when user join or connect the session again from OpenTok closing and opening again.

CameraCaptureSession: Session 0: Exception while stopping repeating: android.hardware.camera2.CameraAccessException: CAMERA_DISCONNECTED (2): checkPidStatus:2047: The camera device has been disconnected

Please fix this issue or let me know if any workaround from app side.

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

To clarify, can you please tell us what the steps to reproduce are? Also, does this affect all Android phones? Or, just some? Thanks!
