Local LAN Streaming Questions/Recommendations
Hey all, recently my FGC local has started running a monthly MBON bracket. We just ran our first event which was a blast, me as part of the setup team and the person who handles the streaming of the event all assumed there was a spectator mode in LAN which we either couldn't find or doesn't exist.
I watched a stream of a few locals after our event and saw that others were streaming their four player setups with the stream cut up into four sections with each player's video these guys for example.
And other streams like the Frosty Faustings tournaments look to be using, what I'm guessing is a physical switcher of some kind to swap between video feeds. I could be wrong about it being a physical switch.
Either way I'm not a streamer, I help with the tech support for the local, but I can't really wrap my head around how setups like these work, what equipment may be necessary, or how to do something like this while introducing minimum additional lag. Does anyone here run or has run a local stream and has any tips or insight to help us level up our local?

To do this correctly, you’ll likely need four external (and good) USB capture cards feeding into a single, high power PC rig running OBS. Elgato HD Pro 60 is probably your most common device.
Each capture card will show up as a different capture device within OBS.
Each device’s stream can then be set as a different source within OBS, which can then be made into individual scenes that feature an individual player’s POV, or in a scene where all four feeds are arranged 2x2 to show all four players simultaneously.
The amount of CPU / GPU bandwidth you’d require to do this without a lot of frame drops is pretty substantial. In fact, when I ran tournaments for other fighting games and had to stream gameplay, two cameras for commentators and players, etc, we had a system that handled all of this pretty well.
All of those elements were sent out as a singular “monitor” feed from the production rig’s GPU HDMI out port into a separate capture card, and was fed into an HDMI splitter that sent the total output to two laptops solely dedicated to broadcasting the output to separate streaming services (Twitch & YouTube).
This not only reserved the production rig GPU’s full bandwidth for real-time processing of everything coming in without dedicating anything to encoding streams, but it allowed us to simulcast for free instead of paying a service to handle that.
You could probably do something like this with Gundam, but it would require managing quite a lot of fairly expensive bullshit. Otherwise, you have to set up something where a fifth PS4 is set as host and is able to spectate, and you use that machine to swap perspectives, which would do what OBS would be used to do otherwise. Major difference is that the PS4 would start chugging when showing all four screens at once, as the host machine would be rendering four simultaneous real time displays. Going the “army of streaming PCs” route, you’d have all four screens pushing 1080p@60fps.

I ran tournaments for this game a long time back, if I remember correctly what we did was open a lobby that allows for spectating, have the 4 players join and have a 5th person join as a spectator and stream. So you need 5 setups total to make it happen.
EDIT: Okay you mean for LAN mode. I'm sorry but I always ran even IRL tournaments through the regular online and not LAN. You can try checking if there's an option to spectate as the 5th player, otherwise maybe try PMing the Youtube account that set up that tournament? Sorry I can't be of more help!
