Question / Help Streaming two screens to one channel [Read on]

[megamidge11]

So, me and my friend want to start doing streaming together.
This is how we picture it;
On the screen, is one of our views fills the screen, while the second person is small in the corner (or not at all sometimes). Then, with the hit of a single hotkey, the roles are switched and it changes to the view of the other person being biggest.

Obviously, we can't just stream to the same channel just like that.

So... what can we do to do this? We've thought about it quite a bit as in ways to do it, but the actual WAY to do those things we're not sure how to do. We have a spare third PC that we can use.

The best way we cam up with is this;
We both use streaming software to record to a video file that can be watched live. This file is uploaded to somewhere and then downloaded to the third (streaming) PC. Basically sent from our PC's to the PC which will broadcast.
The streaming PC then opens these videos up into OBS and multiple scenes are set up to make different views. The streaming PC then broadcasts that, and the two videos are synchronised to be in time with each other. And to change the scene, Both our PC's would remotely be able to just hit a key a on our keyboard and the scene will change on the streaming PC.
This may sound simple (maybe?) but thing is, i have no idea how to do some of this stuff, like the whole sending of video thing.

So my question is, how would i go about doing this? Preferably all the software would be free but we can ''spend money'' on software

By the way, we can't do it in the same building, it has to work over the internet.

if you have enough bandwith, one of you can setup an RTMP server who accepts the others OBS steam, then you use the Videoplugin of OBS to grab this Stream again from the RTMP server and combine it to your desired scene and broadcasts that to Twitch. So far with theory. This setup works with 2 and 3 PCs.

If you're in the same place a capture card would be the easiest way. Otherwise as H4ndy suggested you'll probably need to run an intermediary RTMP server with nginx. Jack0r's guide should help - http://www.helping-squad.com/do-a-picture-in-picture-stream-with-obs-and-nginx/

Would i right in be thinking the idea H4nady has given is basically one person streams toe the other person, than that person combines and broadcasts? If thats the idea then would there not be delay issues, i guess we could sort that out but yeah i guess it could work. But would this same theory work for my theory, with this RTMP server thingy, do it to to the third PC which combines both of them. That way, if there is a PC failure by one of us, there isn't a 50/50 chance of everything going down, as the streaming PC can continue without a second person, and would be easy to set up with endless amounts of people (bandwidth limiting of course)

Ah yes looking at it i can do that (to cut down on performance issues). This is a brilliant piece of information for me, and thank you. This should work perfectly.

oh so this NGINX... yeah im lost with that, looked it up and holy shit its difficult to set up, i dont even know how to start XD
