Having trouble getting started
**Describe the bug**

I have a functioning stream.  I've verified that I can connect to it via IPCams.  It works.   I cannot get Homebridge-camera-ui to recognize it.  

I keep getting the same Error

```
Front Porch: FFmpeg videoanalysis process exited with error! (null) - rtsp://sklass%40foo.com:ZLZJC4%3D@192.168.1.169:8554/10070891: Protocol not found Did you mean file:rtsp://sklass%40foocom:ZLZJC4%3D@192.168.1.169:8554/10070891? 
```

Challenges:

My username has an "@" symbol in it.  sklass@foo.com
My password ends withy a "=" ZLZJC4=

I suspected this was the issue.  I've tried the following
- double quoting the username and paswords
- double quoting the entire thing
- replace @ with %40 and = with %3D
- single quoting completely broke it.

I then suspected maybe my synlology needed ffmpeg so I installed ffmpeg5 with the same results.

I completely understand you are working on a new version.  But could you help another dev out?
