"additionalCommandline": "-aspect 16:9" stopped working?
<!-- You must use the issue template below -->

**Describe The Problem:**
"additionalCommandline": "-aspect 16:9" stopped working. It used to override the aspect ratio coming from my camera to make the video fill my iPhone screen. Now the aspect ration is 4:3, has bars each side and video looks squashed. It worked fine until  recently and I haven't made any config changes but I have updated homebridge and the plugin.

**To Reproduce:**
add "additionalCommandline": "-aspect 16:9" to the config
