I can’t record screen with RepkayKit in iOS when livestream.

When I start camera preview only, it seem to be working.

But when I streaming (start gCoder),

1. I record with camera and microphone, the app still can record but when I saved to photo library video is nothing but white (full white).

2. I record only camera. This func not invoke

```auto

recorder.startCapture(handler: { (sample, bufferType, error) in

**// Not start in here**

**// handle record**

**}** , completionHandler: { error **in**

*print(error) => result nil*

})

```

1. When I start default app record in my iPhone. It can’t record.
