Thanks Walter.
I know BonixTV and it can be a Wirecast alternative, but I can’t use the PiP of switcher.
Most of the time we also need to project the PGM of live switcher during the event.
So we have: live switcher for camera, a mixer for projector (program out, pc, logo, …) and something to re-mix of these two sources for streaming.
A software solution is more flexible than another extron/kramer switcher. (I can customize the stream with logos, text, background and so on.. that I do not want are projected).
I hope that you understand my bad English.
Thanks again
