I'm trying to get together a charity event involving Minecraft and for it I need a way for multiple cameras to be viewed on the same live stream, i.e. switching cameras angles and locations from one point of action to another. I know I'll need a bunch of players to actually be the cameras but does anyone have any idea how to switch between multiple people and desktops on a single live stream? (If you need more information on what I'm doing send me a PM, I don't want it out just yet in case my idea turns out to be impossible)

Xsplit, and some screen sharing software.

However, this gets a bit complex. Even the big streamers can't do this sort of thing. The only ones that do are professional esports presenting teams, and they use specialized software.

I would think the easiest way would be do it all from one computer. Use 2 accounts. Move one into a different position while using the camera on the other, and switch as necessary.

Looking more into it, most charity live streams don't do more than 1 camera angle because it's so much of a pain to set up and do.

You might need to stick with one camera at a time.

What if you had everyone send their screen view to someone deemed to be the "switchboard?"  (through like a video chat software or something)  That switchboard person could have the livestream software recording his screen (or an area on it) and switch between camera views as wanted.  Just pull up views into the recording space as you want.

Edit: Now that I think about it, what kind of bandwidth would the person acting as the switchboard have to have?

Most live TV shows that want multicam use AVID Media Composer. That is, IIRC, $2500. Yeah, it isn't cheap nor is it easy to do, as MC isn't something you can just walk right into.

Gigabit, at least.

100Mb/s would not be enough for multiple streaming cameras.

But that is easily achieved over LAN.

So if they are doing this as a LAN party it could work?  Although, transitioning from one camera to another might look a little funky.

Yes but again, they would need expensive software.

Xsplit sort-of has support for this kind of thing, as does flash media encoder, but the problems are that it is not really fleshed out at all and does not work terribly well on xsplit's end because that part is still in beta, and flash media encoder just plain sucks.

I think he means screens, as to have different perspectives in, say, a minecraft server from different people's points of views.

Multiple Skype video calls with the person acting as the switchboard?  Gamers share screen, switchboard switches which person's video he has up, records results.

Of course it would probably look like it was recorded with a potato.

Thank you all for your ideas, the central hub acting as a switch board sounds like the most likely method and easiest. Once I get everything all set I'll make a post for participants so you'll be free to join (assuming I can even find the time to do this)

If all else fails, You could try getting everyone to stream to their separate twitch.tv (or equilivant) and put them all on your website - If you are to have one.

After reading this thread.

The way I see it, either have everyone prerecord their screens and merge as interesting things happen "how yogcast do it for a poor example".

However this is not Live. Live gets far more tricky as you need switching and it is best at LAN. Such as during the Halo4 livestream on youtube that went on for like days, it was just 2 people in the same room, 1 guy controlling the screen switches and camera that is in the room "that shows them".

The setup looked complex and given this was Machinima, you can only imagine the cost for the equipment.

Xsplit is about as close as can get perhaps. Though I am not sure of its limits when it comes to things like this.

Either way, you will need a powerful enough computer to pull this, i7 preferred to handle the massive grinding.

LAN setup if all possible, or some very good bandwidth, 35Mb up and down minimum for the main computer, everyone else of course needs 10mb minimum up and down, 5mb at most.

This is why mass media is a nightmare just to say. Glad I never get involved nor take part in these things, for this reason.

However good luck to ya, as its all dependent on setup and organizing.
