We have a setup where we receive IDTV streams on a server, from where they get bundled via an application and sent out on a multicast stream via a VLAN.
These video streams get played out on a big screen via VLC so we can monitor them.
Now the thing is this used to be working like a charm but all of the sudden, some streams are not sent out anymore and so the big screen with different streams is incomplete now.
I've created a mirror port on the switch where this device is located that runs the application to bundles the stream, sends it out on the network, and i can see different multicast streams are living on this particular VLAN from the switch perspective, but when i do a packet capture on the machine itself, i can't see these streams but only 1 and as a result, they are not visible on the TV where we monitor the streams, only 1 of them is available while there should be around 5 or 6 different streams.
I'm new to multicasting in general and have no idea how to troubleshoot.
We don't use multicast routing, the multicast video stream is passed onto a single VLAN.
Where and what to look after?
