loglevel error (+verbose)
- plugin v3.1.4

The line above is generating an error with the loglevel, enabling debug in homebridge i saw this :

`-loglevel level+verbose -progress pipe:1`

ffmpeg requires something like "-loglevel verbose" without that "+" sign.

I changed:
`ffmpegArgs += ' -loglevel level' + (this.videoConfig.debug ? '+verbose' : '') +
' -progress pipe:1';`
to
`ffmpegArgs += ' -loglevel ' + (this.videoConfig.debug ? 'verbose' : '') +
' -progress pipe:1';`

and now works like a charm
