[BUG] - ERROR: FFmpeg exited with code 1
I've an Raspberry Pi 3 B+that hosts Homebridge and installed plugin on it. Whenver I try to use livestream from Home app, it doesn't work and I get the message `[Dafang] ERROR: FFmpeg exited with code 1` in the logs.

When I try to check the stream from another machine, it works just fine from VLC on Mac. You can see part of my configs below:

````
"cameraName": "Xiaomi Dafang",
                    "cameraRTSPStreamUrl": "rtsp://USERNAME:PASSWORD@10.0.100.106:8554/unicast",
                    "videoConfig": {
                        "source": "-rtsp_transport tcp -i rtsp://USERNAME:PASSWORD@10.0.100.106:8554/unicast",
                        "stillImageSource": "-rtsp_transport http -i rtsp://USERNAME:PASSWORD@10.0.100.106:8554/unicast -vframes 1 -r 1",
                        "maxStreams": 5,
                        "maxWidth": 1280,
                        "maxHeight": 720,
                        "maxFPS": 25,
                        "debug": true,
                        "audio": true
                    },

In addition, I have two more cameras which has Motioneyeos and Motioneye server running on same Raspberry Pi. I've them in my Homebridge as well with `homebridge-camera-ffmpeg` plugin and live stream for them is also working fine.

What might be wrong with my configurations? Do I need to enable/disable some services from Dafang web interface?
