Question / Help Lan Party Streaming

[SenorBoBo]

I'm going to be having a Lan party in the near future and would like to steam MULTIPLE PC's to a single twitch page.

What I'm thinking is to have one "streaming PC".
5-10 people stream their game play to the "streaming PC"
Have some sort of organization of all the streams, with the ability to select one and make it larger then the others.
That would then be uploaded to twitch.

A lot like the League of Legends LCS streams. But im not sure how to go about doing this. Any info would be great!

Thanks!

The league of legends streams you refer to use a 'spectator' client, that allows them to view over the entire game at one time. you'd need 1 capture card for every single console you wanted to capture, and truthfully, it wouldn't be a good idea.

If I may make a suggestion, you could try simply doing two streams with two players, one from each time and setting up a multitwitch (Streaming to two twitch pages, using the Multitwitch website to load both on the same page. ) And then going through that. Capturing 5 to 10 PC's one one central PC just isn't a feasible feat.

Yep, a capture card per machine. Plus switching audio from each on and off on the fly would prove a bit challenging.
You might look on eBay for Datapath Vision E2(s) cards, which each do two inputs, but don't capture sound. They have the advantage of being designed for use in a large capture array though, and can support up to 8 cards (so 16 inputs) in one machine. You'll probably want a dedicated capture/OBS machine, and a standalone encoding box to be able to handle the capture overhead for that many inputs, too.

You can't really stream from each system to a central machine at this time, effectively.
It'd be possible to use an nginx relay for each system and then capture each of those via an instance of VLC on the OBS machine, but the overhead for that would be even bigger and heavier. Also very technically challenging. Plus, the gameplay would not be in sync; probably would have a 2-6 second drift between machines.

While you can resize sources on the fly, there's nothing like LCS uses to expand one while shrinking the others, or animate-popup an overlay or picture-in-picture. They're on custom casting software which is probably rather expensive.
