I was experimenting with setting up SRT on vMix, created port forwarding rules, disengaged local WiFi and accessed
vMix input : Listener, port 9023, streamID : vmix1
using Larix Broadcaster on my iPhone. No problems.

Then I created another SRT
vMix input : Listener, port 9023, streamID : vmix2
and used SRTstreamer from GaraninApps.

The SRTstreamer took over the iPhone input and blocked it, but did not open in the dedicated Input I created with the vmix2 streamID.

Not until I changed the port number to 9024 in both the SRTstreamer and the new input, it released the iPhone vmix1 input, and became visible in the dedicated Input.

My question is therefore;
- Can't I use a single port number for multiple SRT streams coming into my vMix system and differentiate between them with streamID's??
