After some services were recently quieted down by adjusting the log level for e.g ffmpeg. It would be nice if the user can easily adjust the log level again so that that they can investigate or debug a issue since output is not generated by default, so now the Livestream, Spectrogream and Birdnet Recording have a adjustable log levels to help with this.
