Not respecting config parameters
I have several config parameter setup with values greater than the default, but ffmpeg is being called with the default parameters. Here is my config:

                    "videoConfig": {
                        "source": "-re -i rtsp://user:pw@<ip>/live",
                        "stillImageSource": "-i rtsp://user:pw@<ip>/live",
                        "maxStreams": 2,
                        "maxWidth": 1920,
                        "maxHeight": 1080,
                        "maxFPS": 30,
                        "maxBitrate": 1200,
                        "vcodec": "copy",
                        "packetSize": 1316,
                        "audio": false,
                        "debug": false
                    }

Here is the output I see from ps:
```
ffmpeg -re -i rtsp://user:pw@<ip>/live -map 0:0 -vcodec copy -pix_fmt yuv420p -r 10 -f rawvideo -tune zerolatency -b:v 299k -bufsize 299k -maxrate 299k -payload_type 99 -ssrc 2154094 -f rtp -srtp_out_suite AES_CM_128_HMAC_SHA1_80 -srtp_out_params ukjECQnaBVr52tmMbojbZYhOqHdfptj8sOT+Guk+ srtp://<phone ip>:58842?rtcpport=58842&localrtcpport=58842&pkt_size=1316
```

Note: I removed private user/pw/ip

The problem i'm seeing is bad streaming quality. When debugging I'm seeing a lot of timeouts. This was working well about a month ago. 

Specifically the output from ps is showing -r 10 indicating 10 FPS when I specified 30. It also appears to be specifying 300kbit is several places when I specified 1200.
