I was thinking more along the lines of the NDI transport itself. It does have to be compiled with the NDI SDK however, so I'm not sure if this is possible license-wise.
any chance to include ndi support for future releases? it's getting attention now it's out and it's very useful for live transcoding and related tasks.
