FFmpeg exited with code 1
I keep getting the problem with that the homebridge-camera-ffmpeg package camera stream won’t start (keeps loading and eventually times out) and outputs the error: FFmpeg exited with code 1 in the logs. 

FYI, I'm using the debian release on my Synology NAS

I added it to the PACKAGES=ffmpeg list, but no success.
I didn’t do anything special in the setup. Homebridge literally consists of this camera accessory and nothing else. Is it working for anyone?
