Proscan is greatWell worth buying ProScan - do it...
Does that happen when VLC is running or when VLC shuts down? VLC should be sending a keep-alive packet about every 20 seconds and a TEARDOWN command when VLC shuts down. My ProScan and free RadioFeed detects the condition and can recover the audio by sending a MSM,1 command provided the scanner Ethernet/LAN is communicating.The bug with the scanner not realizing the RTSP connection has gone away, so it never drops it internally and resets to accept any future RTSP connections without resetting the scanner, is annoying though. I hope @JoeBearcat has that on The List.

Also the RTSP protocol doesn't permit 2 or more connections at the same time to the same scanner. So if using VLC then don't use ProScan/RadioFeed at the same time or visa versa Throwing that out there just in case. Also don't use AVG antivirus software, if you are, as that program will interrupt the TCP packets.When I've seen it, I've had VLC up for a while on a tablet and the audio stream has stopped for some unknown reason. The network has been up the whole time, no problems other than if the VLC stops (and it can go a very long time before it does usually), it won't recover. I can exit the VLC process on the tablet an restart it, and that won't help. I haven't tried to enter anything in the command interface on the LAN port to reset it, I should try that. I might also set up a sniffer and watch the Ethernet traffic on the RTSP port to see what's going on there as well.
But to answer your question, it happens when VLC is up and VLC is still running, but the audio just stops and can't be restarted without restarting the SDS unit. I might be better off if I can use ProScan as a proxy for this anyway though, I should look into that. Because if your software, on the server side, is multi-threaded so it can accept multiple concurrent connections, that would probably solve the whole problem.
I wasn't aware of the multiple licenses purchased so I would use ProScan.Maybe I'll give RadioFeed a shot and see how that goes. I didn't know that about RTSP; thanks for that info! I still need to get the remote control/remote listening features of ProScan figured out, that would actually be best (I actually bought multiple ProScan licenses so I'm all set there, just need to figure out the remote scanning/listening things--I seem to have some problem getting my audio connection to work so far when I try it). But knowing what you said about RTSP only allowing one connection because of the protocol spec is very helpful and I can now understand some of the problems I've likely been running into, so that'll help me sort this out I think.
