I have an event where the client wants a five minute delay between realtime and sending to a livestream. It's so they can stop the stream if anything is mentioned that is not supposed to be going out over the stream.

I can easily set the 300 second delay, and see that that is working, but how can I determine how long after stopping the stream in vMix, it will be safe in Wowza to start streaming again? I did put a timer overlay to test, and it seems that there was approximately 34 seconds of the data that was still in the vMix outgoing buffer was still streamed out after I stopped the stream in testing, but it wasn't consistent.

My question - if I am instructed to stop the vMix livestream, and then restart it within those 30-35 seconds, will the other 4 ½ minutes of data be lost, or is there a chance that when Wowza sees the stream data come in very shortly after it is stopped, it will still get the rest of the data that I was trying to exclude? Would stopping and starting the stream in this manner be a safe way of censoring something that was said within that 4 ½ minutes, or would it be safer to also shut the stream down in Wowza, and then start that back up, too?
