Feature request: Raspberry Pi CM4 hardware transcoding support
<!-- BUG REPORTS THAT ARE NOT FILLED OUT COMPLETELY WILL BE CLOSED AUTOMATICALLY WITHOUT WARNING AND WILL NOT RECEIVE A RESPONSE. THE FORM IS HERE FOR A REASON. :). -->
<!-- Please ensure you read the documentation before creating a support request, especially the Troubleshooting page. -->
<!-- BUG REPORTS ABOUT BETA VERSIONS OF UNIFI / UBIQUITI FIRMWARE OR EARLY-ACCESS/BETA HARDWARE WILL BE CLOSED WITHOUT A RESPONSE. ALL BETA RELEASES FROM UBIQUITI ARE UNSUPPORTED -->

**Describe The Problem:**
When I check the "Use hardware-accelerated transcoding when available (Apple Macs, Intel Quick Sync Video-enabled CPUs, Raspberry Pi 4)." setting and restart homebridge, I don't see the "Hardware accelerated decoding and transcoding" message when running on a [raspi CM4](https://www.raspberrypi.com/products/compute-module-4/).

My guess is that:
- The CM4 isn't being detected as a raspi4? 
- The CM4 doesn't support hardware decoding
- I need to change some additional ffmpeg setting.

**To Reproduce:**
<!-- Steps to reproduce the behavior. -->
Run this plugin on a CM4 and enable hardware transcoding.

**Logs:**
<!-- In order to be helpful, include the relevant logs from Homebridge, if applicable. -->
