Moved to new Mac with M1 chip, video not loading
<!-- You must use the issue template below -->

**Describe The Problem:**
I just moved my Homebridge install to a new Mac Studio with an M1 Ultra chip. The streams that worked on my previous machine don't work now.

It seems M1 chips install ffmpeg in a different location, so I updated the plugin, but am still seeing errors.

**To Reproduce:**
Run a stream from a camera on an M1 Mac with ffmpeg installed in a different location than default.

**Logs:**
