Re: [GnomeMeeting-list] Urgent:Multi-camera


I guess you are students and you have an assignment, right?

My idea would be to create a new video plugin called "MultiCamera" that
returns a predefined device "CameraArrays". It would simply be an
enhancement of the V4L plugin, but reading from multiple devices at the
same time. The trick is to mix together all the images from the various
devices and to return only one unique mixed image to GnomeMeeting.

The only problem you will have is to find a common color format for all
cameras if they are different.
