Yes i saw it in version 2.29.5

I think it can be very useful. For other applications who uses a webcam

All right , I go to have closer look on cheese source code.
What it is the GNOME user account dialog. It uses a camera ?  I m' just
a gnome user ;-)

No I'm not aware of the camerabin. It is new ? I don't have it in
gstreamer 0.10.14 under ubuntu karmic. According  doc it looks very
useful for my needs !

I don't know if it is possible. Its true that stuff in cheese is
duplicated in luciole.  And the same philosophy on the easy to use.
Luciole is intended to be used also by children

For stopmotion I have some specific needs : as fitting the image size in
a DV format, and 2  treeview with image . One for the acquired image
like in cheese, and another for mounting ( like a timeline) . In this
one I can change the image order, duplicate /delete/import image , set a
framerate, and a preview of the movie ( sequence of image). And also
some other specific features like export to DV or MPEG2 format, and
export for other video tools ( cinellera/pitivi/kdenelive)

By the way , I'll be pleased to work on cheese  for the webcam
detection  library and python binding (even if I never work on writing
code bindings) and more ...


Ciao
