[Bug]: [Doorbell] [Video Process] FFmpeg exited with code: 0 and signal: null (Expected) on Live Streaming
### What happened?

This is probably less of an issue with this plugin, but the Doorbell will not stream video in the home app, all the other Eufy cameras work fine with this just not the doorbell. 

I enabled debugging and ffmpeg debugging.  I see this in the logs if thats helpful
