[Feature] NDI Support for broadcast view

[neomatamune]

A NDI support for the broadcast view could allow easier multi-pc setups for streaming.

Wiki page about NDI : https://en.wikipedia.org/wiki/Network_Device_Interface

It is actually added to emotracker's broadcast allowing :

• Streaming PC to receive the content of the broadcast view without the need of a screen/window capture of the PC with the tracker (so the tracker can be set up on the gaming PC)
• Use of NDI source with transparency capacities instead of "capture window" which would force the use of a chroma key to have a transparency

If NDI is not a target choice, maybe a web socket could allow an equivalent result.

Will look into that. SDL can render off-screen with alpha, so that would also be nice on localhost.

Which plugin do you use in OBS? https://github.com/Palakis/obs-ndi ?
We can maybe even reuse code from that OBS plugin (since it's GPL).

As I'm using Streamlabs OBS I'm using their "native" plugin
I set it up following this tutorial : https://streamlabs.com/content-hub/post/ndi-receiving-setup-in-streamlabs-obs

Not sure if any progress has been done on this. If NDI doesn't work out, though, Spout may be an alternative. veadotube mini (a PNGtuber application) uses that. NDI would be a more seamless solution for people using Emotracker, though.
