Frigate Watcher

A quick and dirty script to handle No frames have been received, check error logs quick and dirty.

This script checks through the frigate stats if the ffmpeg process is still running. If the consecutive fails hit the treshold has been registered for your camera, this script will reboot frigate. The failure count is recorded at the MQTT topic frigate_watcher/[camrea_name]/failure_count. As soon as the ffmpeg pid of a camera is found in the stats, the counter is set to 0.

After a reboot, ffmpeg processes will spin up to restore the connection with your camera. If, for instance, the camera has been shut down, frigate_watcher will reboot frigate until the power is restored.

This script is not meant to run as a service, it could be a cron job for every x seconds.
