Re: [Linphone-users] linphone and webcam video not working

This camera is working only in QVGA mode: I'm using it with mediastreamer2
and have fixed the CVS 2 days ago to make it work :)

I don't think linphone can currently handle the workaround that was found
for mediastreamer: a resizer must be pluggued after the capture filter and
I don't think there is one currently? Simon? Can you comment on this?

The problem is with that driver or camera that isn't able to provide the CIF
or QCIF standart resolution.
We are working on this problem to find a workaround in linphone.

Hello all,

I've been using linphone for a while now and it seems great! However, now
I needed to use it's video capabilities with a webcam (Logitech Quickcam
Messenger Plus) and looks like linphone doesnt know how to set the devices
properties right:

This error above is repeated endlessly until I hit the 'enable video'
button again to make video window shutdown. The driver for the webcam is
qc-usb-messenger-1.6 and here's what it's conf program tells about the

Otherwise my system is a FC 3(also tried with FC 4) with kernel
I tested the webcam with gimp & sane and it produced a fine picture so the
v4l should work. Any ideas how to get video running?
