[jitsi-users] Jitsi and Network Streaming IP Cameras


#1

We have a conference system setup that uses a combination of

Asterisk, Medooze with Jitsi as the clients.

It works well enough, but we would like to be able to do a couple things:

(1)We would like to be able to use a network streaming camera as the

video source going into Jitsi, rather than a directly attached USB

webcam. Is this something that Jitsi is capable of?

(2)Is it possible to be able to change the video source during a

teleconference. For example, where a Jitsi client is gathering sound

and video of a number of people gathered around a table at one of the sites.

We would like to be able to change the video feed between a camera

that is viewing all of the conference table, and another camera that

is focused on a single presenter. Is this possible?

Hey Stephen,

Not out of the box. At least not unless you have a driver that makes the camera appear as a local device that can be queried for supported formats and that can then actually provide media in a raw format.

Something like this could of course be developed but it would be a non-negligible effort.

(2)Is it possible to be able to change the video source during a
teleconference. For example, where a Jitsi client is gathering sound
and video of a number of people gathered around a table at one of the sites.

This works a lot better with audio than it does with video. YMMV so you best experiment with your setup (you may need to turn video off and then back on in between changes).

At some point we will need to work on video hotplug so this will be improved.

Cheers,
Emil

can then actually provide media in a raw format.

I take it you are not aware of any software that does that already?

Something like this could of course be developed but it would be a non-
negligible effort.

How much effort do you think something like this would take, and at what cost?

It would probably be a non-negligible effort but the specifics would depend on the camera and the developers. I personally work for a company that provides such services so feel free to contact me personally if interested (others here may also let you know if interesting in freelancing this kind of effort).

Cheers,
Emil

If it is off any interest...

I have discovered that since the improvement in support for DirectShow devices under UVC the it is now possible to use streaming IP cameras with Jitsi, which addresses an earlier query I had.

I found a blog (alax.info/blog/1216) that described a DirectShow wrapper for HTTP based JPEG/M-JPEG streamed video.

I used the updated wrapper from Alax.info/blog/1223, and managed to get the image from an Axis 2100 network camera to appear in Jitsi. The "IP Video Source" wrapped stream shows up as an available device in the Jitsi configuration menu for video devices.
