@EasyWorship: Could this topic be moved please to the EW7 forum as that has been released since I first posted this?
FYI anyone else reading, there is a workaround available that you can use. If you download NDI Tools from NewTek, you can make VLC send an NDI stream. So you get VLC to receive your IP Camera stream as RTMP/RTSP/whatever, get VLC to send it back out as NDI, and bring the NDI into EasyWorship as a feed.
Not ideal, but a useful workaround for now.
