Stream interruption on connection changes and front camera switch

[arkadiyo]

Hello.
We had the following problem when using the library.
We broadcast from the iOS application to the nginx-rtmp server. In most cases, it have no problems. However, we are faced with two issues that we cannot resolve yet:

1. If during a broadcast via Wifi, switch the phone to a mobile network (turn off WiFi), the video stream is interrupted in wrong way (rmtp-server does not raise the necessary events for the correct completion of the broadcast).
   Is it possible to continue an interrupted broadcast or, for example, use a buffer which can help do stream more stable on connection problems?

2. On some old devices, such as the iPhone 5s, if we are trying to switch to front camera, the video stream is also interrupted incorrectly. The audio continues to be transmitted but have no video. Sometimes it can "slow down" stream (and device i think) for a few seconds, but then it is also interrupted. On more modern devices (iPhone SE and above), switching the camera does not cause problems.
   Can you help us to solve this issue? Or give some advice what we should try?

Thank you.

1. If during a broadcast via Wifi,

You can get "NetConnection.Connect.Closed" event.

rtmpConneciton.addEventListener(Event.RTMP_STATUS, selector: #selector(rtmpStatusEvent), observer: self)

    @objc func rtmpStatusEvent(_ status: Notification) {
        let e: Event = Event.from(status)
        guard
            let data: ASObject = e.data as? ASObject,
            let code: String = data["code"] as? String,
            let streamName: String = streamName else {
            return
        }
        switch code {
        case RTMPConnection.Code.connectClosed.rawValue:
            stream.publish(streamName)
        default:
            break
        }
    }

2. On some old devices, such as the iPhone 5s

I have no iPhone5s. I can't help you.

Thanks.
