Hi list, I recently decided to try the following setup: mpd is running on my NAS machine with jack audio outputs and ympd as web interface. The jack server uses the dummy backend but has the netmanager loaded. The problem is that mpd sometimes deletes its jack ports and created a new pair. And since the number and names of the connected net slaves varies, I thought a classic session manager might not fit (admitting that I didn't really try it). So I created a small program that registers as slave without ports but watches for new port registrations. If a pair of out- and input ports matches their regular expressions specified on the command line, they are connected. I used Qt to solve the problem that ports cannot be connected in the same thread that the notification-callback is executed. Using the QueuedConnection, the SLOT (reaction to a SIGNAL event) is executed in the receiver's thread. To solve the challenge I'm using this command now: jack_autoconnect "Music Player Daemon:left" ".*:to_slave_1" "Music Player Daemon:right" ".*:to_slave_2" The system is working pretty well. The music and playlists can be controlled from any device with webbrowser and multiple playout machines connect via NetJack to the NAS. And the synchronization between all of them is just perfect! The code is on github: https://github.com/kripton/jack_autoconnect Comments are welcome :D A big "Thank you!" too everyone who makes all of this possible!
