Add support for capturing indivudal video sources on OBS (NDI suport or StreamKit)

Hello!

I use discord to videocallls, but when it comes to streaming in OBS, I need to use Skype because it supports capturing each person on the call as an individual source through NDI Plugin.

StreamKit is great, but it doesn't support video. Capturing the entire windows doesn't work because the places in the call grid are not pinned, they change everytime someone enters or leaves the call. 

Please add NDI support, or another way to capture each person as an individual source through streamkit. Or maybe an option for pinning cameras on the call.

Thanks.
