Re: [GnomeMeeting-list] Firewire Video scaling with Coriander & vloopback

[Erik Chakravarty <e chakravarty sms ed ac uk>]

Well if you want any testing / debugging done please let me know I'm
more than happy to contribute to the effort. My webcam is an
IIDC-compliant Apple iSight, and I run Ekiga 1.99b on an Apple PowerBook
(Debian/PPC unstable, kernel 2.6.15-1) with videodev modules and
vloopback modules inserted.

Coriander seems to be able to route only YUV format video through to the
V4L device. Is this a palette that Ekiga should be able to resize?

For the time being it's just a little inconvienience having to sit back
from the camera. I don't think it's that important to have native
firewire / IIDC webcam support built into Ekiga because it's easy to use
Coriander to get V4L output and for camera control, but it'd be quite
nice to have a scaled stream if it's possible.
