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

[Aymeric Moizard]

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?

tks,
