Unable to view feed or snapshot - FFmpeg exited with code: 1 and signal: null (Error)
**Describe The Problem:**
When using an RTSP camera on a local network, I am unable to view the live feed or snapshots of a camera. This camera is a Wyze Cam v3 that is visible using the Wyze app. 

**To Reproduce:**
Using the Hyper-V ISO running Homebridge 1.5.0 and homebridge-camera-ffmpeg v3.1.4 with a non-custom install of ffmpeg.

**Logs:**
