Hi, this is not really a VMix question specifically but there is a lot of expertise here and others may have done this.
We use VMix to livestream our church services from our rented meeting venue in a school (morning and evening on Sundays). The morning service goes to a single stream but the evening service is a combination of several churches meeting together so that is streamed to 3 different channels (for each church).
For various reasons we have had unreliability in the streaming PC which causes the stream to stop being sent (I won't bore you with the details but things like mains power failing, bluescreen on the PC, random disconnect from school wifi).
Youtube allows the incoming data to drop for about 60 seconds before they end the stream and you have to start a new event, which is quite time consuming (especially for the triple stream) and viewers have to go find the new event. While we chase down all the gremlins I would like to setup a fallback solution which continues to send data to Youtube - maybe just a static caption - to keep the stream events active and viewers online while we get the main stream going again.
Question is, is there an automatic way to do this by sending a backup stream from another laptop (could be just a static caption). If you send a backup stream to youtube's backup ingest there doesn't seem to be a way to control which one gets used, and we'd need the main stream to be sent by default. We could just have a laptop running VMix standing ready, which we manually click "Stream" on, if the main PC falls over for some reason, it's a bit hacky but this is my current idea to try.
Thanks for any good ideas...

Thanks for any good ideas... Have a second stream go to the same key/event when the first one goes out the second should take over

If you send both at the same time, you can't control which one youtube uses (as far as I can work out). So if one is a backup graphic, that can get broadcast even if the main stream is still healthy.

When I tested, it seems unpredictable. I don't want it swapping to the backup graphic mid stream when the main stream is OK. Does the stream you started first always stay active in your experience (unless it fails)?

Does the stream you started first always stay active in your experience (unless it fails)? it only kicks in whenthe primary stream fails ie yt not receiving its signal Can not test so long the primary is ok try stopping the prim stream while te second is allready running or started when you induced the fail as that is the scenario you where refering to
