afaik there were two problems, depending on the version of the
underlying fedora.

a) gst-plugins-good (with the v4l2src plugin) was not installed
b) the user "olpc" was not inside the "video" group

furthermore, i got some segfaults when i tested record on a fedora 12,
coming from the cairo code (which is calling the installed cairo lib)
which is used by record. however i did not manage to track down that
bug.

we (cheese) want to use camerabin too, and thats where we are heading
for the next release. camerabin does a great job of simplifying the
whole process of taking photos and videos. it is already in use in the
nokia n900 device. please be also aware that camerabin is still in
gst-plugins-bad and is not finished entirely.

see this wiki page for further information:

hope this helps! ;)

best, daniel
