/dev/v4l/video0, listed above.

Error while opening video device /dev/video0
The chosen Video Image will be transmitted during calls. If you didn't
choose any image, then the default GnomeMeeting logo will be
transmitted. Notice that you can always transmit a given image or the
GnomeMeeting logo by choosing "Picture" as video device.
Could not open the chosen channel with the chosen video format.
