[openob-users] Re: multiple sends

One openob receiver will listen to only one transmitter at a time. In the unicast mode one transmitter only talks to one receiver for the session. in the multicast mode one transmitter can talk to several receivers at a time. You can run several openob receivers and transmitters on the same computer and internet connection if you have the bandwidth.

You can have one receiver listen to a number of identically configured transmitters, but only ONE AT A TIME. You only need one redis server no matter how many links you have.

You should NOT expose an redis server on the internet as it has no authentication. There is a very good workaround at: http://spipe.sourceforge.net/#description There may also be another vulnerability because the openob audio connection is not encrypted, but I have not figured that out.

If you are sure that the one programmer will disconnect before another one connects, one receiver should do.   If they stay connected, they will block any additional connections.

If someone stays connected past their scheduled time any noise that they send would be added into the mix.

you could use a cron job (Or have your automation kick off a shell or .bat script.) the script would open a new instance of openob receiver shortly before each show is scheduled to open with its own link name,  and  the script could sleep until the first  show ends, and then kill the original openob receiver. After starting the new instance of openob, You could also  pipe the standard output of the new openob receiver to grep looking for "INFO - Receiving stereo audio transmission"wait until that is received, then kill the old instance of openob receiver when the new show is scheduled.  That would will maintain an active link open until after the new one actually starts. (a fallback in the case that a programmer fails to connect.) Openob closes its Jack port when it disconnects.  I usually put up a meterbridge -dpm  that listens to each openob link  receiver before any mixing so you can see whether it has audio.  You can sum the outputs of meterbridge, as they stay up continuously, whether openob receivers are connected or not.
