Show Multiple Cameras from Single User/Computer

Since USB cameras can run full HD under $100, it is economical to deploy more than one in a room.  We have two rooms with a camera showing the audience and another mounted near the projector to show the speaker.  However, we only have one PC per room which is used to dial in to BlueJeans.  While the settings can be changed to switch between the two cameras, we would like to be able to show remote participants both views simultaneously without adding a second PC and having to join the conference twice.  I have heard that another solution may support simultaneous viewing of multiple cameras attached to a single PC.  Does Blue Jeans support this in some fashion or is it an idea (I have searched and did not find)?

Currently Blue Jeans, in terms of the existing web browser plug-in does not support this. For that matter, most standards based solutions wouldn't either.

I'm curious though, why? In theory only one view has an active speaker at any given time so I'd be opting for some ability to do some intelligent voice switching if possible, but in the same room that becomes not easily accomplished.

You don't want to say the other solution's name? I'm interested to know, just to know.

As a far side participant to a presentation, especially an interactive one, you really want to be able to see the presenter and the audience.  My account rep asked if I had tried relaunching BJ in a second tab under a different user and I have not.  I will give that a try, although I was really excited about the desktop client and it may or may not support running dual instances (maybe if installed in a separate directory).

As far as the other solution is concerned, an A/V engineer I have been working with said that he thought Clear One's Spontania supported it, but I did not see anything like that touted in their online materials.

That makes sense. We've just been in more technically capable rooms in that case, a full blown classroom for example. When a student's/audience members' microphone is un-muted the system has the ability to switch to that camera and even zoom in on them. Once they mute it goes back to the previous camera shot automatically. Granted, that's not necessarily an easily affordable solution.

I've not tried two windows. You may need to fire up two different browsers, too perhaps.

I'm not familiar with the dual video capability in Spontania either.

You can do this with Cisco C-series and SX-series TP devices. They have an application called TC Console that allows you to mux every input into the primary video stream -- or any variation thereof. We use it to grab a panoramic view of an extremely wide classroom and stitch them together into a 'super letterbox' image. Works very well, but obviously more expensive than what you were talking about.

I'd be shocked that there isn't some desktop software that does the exact same thing prior to BJN getting the stream?

Check out CamCamX (MacOS only) but it seems to do what you need.

ManyCam can do this on Windows.

We've actually done this with a combination C90 for the primary view, and laptops with BJ client running to shoot from the sides and muting the audio and speakers on the laptops with BJ client. 

Seems to work just fine.

Multi Stream video conferencing is actually something I've wanted to see happen for a long time, but other than some research projects I've been involved in (multicast video conferencing) it's not something that's in high demand.
