I don't know what's the flicker, but I think it is soemthing that should
be related to your driver.

Currently, Ekiga can only do 176x144. In the next few weeks, thanks to
the hard work of Craig, it will also be able to do 352x288.

I know no free codec that can do that with a reasonable bandwidth for
home users.

Go in the View menu, you can apply a 2x zoom on the picture.
