I have a possible project that might be a bit backwards. There's an existing surveillance installation; few cameras, and a network video recorder.
I know that I can bring the cameras into vMix. Easy. Peasy. Done it dozens of times.
What I'd like to do is stream the output of vMix to the NVR. It would essentially mimic another camera.
This would be used to aggregate some instrumentation that would be recorded as a video stream in parallel with the cameras. That way on playback everything would maintain sync in time.
Any tips on how that might be accomplished?
Michael

Sure, with ffmpeg and vMix DirectShow as the input.

Steve Not clear what you mean by that. I want the output of vMix to be in a format that can be passed to the NVR as it it was another camera.

What resolution is the NVR expecting? What connection is the input for the NVR (I would Imagine BNC)
Chuck
EDIT: I see what you are trying to accomplish now. I don't know how you would get the software to see the vMix output as a security camera. What software are you using?

The NVR can be set to expect and resolution. Let's say 1280x720p30 for now. It's an NVR, so all connectivity is via IP. No BNC type connections. It truly is a case of making the output of vMix emulate an IP camera.

This probably is way off base, how about some variation Local Network Streaming? Quote:http://www.vmix.com/knowledgebase/article.aspx/23/local-network-streaming

FFMPEG (or VLC) can turn the vMix output into any flavor of streaming you want. It would be hard for a tutorial here, but google is your friend. Example: ffmpeg -f dshow -i video="vMix Video":audio="vMix Audio" -vcodec libx264 -tune zerolatency -b 8000k -f rtsp -rtsp_transport tcp rtsp://localhost:8888/stream https://trac.ffmpeg.org/wiki/StreamingGuideSteve
