Toggle camera slowing down ui

[markmark1]

Ui gets slowed down a bit noticeably while the camera is toggled what is the solution to this as uiviews cant be manipulated in the background thread? thanks a lot for an amazing library

Switch the camera asynchronously? I did something like this:

- (IBAction)changeBroadcasterCamera:(id)sender {

    switch (_session.cameraState) {
        case VCCameraStateFront:
        {
            dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_BACKGROUND, 0), ^{
                _session.cameraState = VCCameraStateBack;
            });
            break;
        }

        case VCCameraStateBack:
        {
            dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_BACKGROUND, 0), ^{
                _session.cameraState = VCCameraStateFront;
            });
            break;
        }

        default:
            break;
    }
}

Josh it becomes very responsive but the view flips to horizontal orientation for a second before going back to portrait looks bad

Is there any alternative to fix that thanks

I know of that issue, thought there was an open bug for it. Search around, otherwise feel free to open a new issue. Are you using the latest version of classes in the repo?
