FFmpeg crashed on HD mode.
Great Plugin, 


The issue is that whenever I set the camera stream to HD.

```
                    "hksvConfig": {
                        "source": "-i rtsp://some@192.168.0.25:554/stream1",
                        "audio": true
                    }
```

Logs returned with below

```
[6/2/2022, 12:51:18 AM] [CameraUI]  ERROR  Main Door Camera: FFmpeg recording process exited with error! (null)
```

At the same time, another camera with the same make is working fine on the same network, same Homebridge setup.

I am using TP-link Tapo C200.

Thank you.
