How to add new stream without reinitializing Vision Mixer object?
From AVObjects Knowledge Base
It is not possible to add new stream without reinitializing vision mixer object, but it is possible to change type of existing one.
So before initialization you need to decide, what is max number of streams your mixer will have on the input at the same time and add correspondent number of streams.
For example you need to use 2 streams right after the initialization, and add third one some time later. You add your 2 streams from live devices and 1 simple stream (like bars) that exists in mixer object, but not shown. When you'll need to add one more stream from live device - just change the type of your simple stream to this live soure and show it.
