Issue background

I'm having having problems with skype under linux. My video calls are all the time non-continuous and they're getting stuck. The situation is the same whether I use skype alone, or with a preload:
LD_PRELOAD=/usr/lib32/libv4l/ skype &
LD_PRELOAD=/usr/lib32/ skype &

Turning-off (compiz) graphical effects in KDE or switching to LXDE (openbox-lxde --replace) doesn't help much.

From atop I can see that my outgoing traffic so is around 1500Kbps while incoming is around 150Kbps. When I select stop my video the outgoing traffic immediately falls to 70Kbps.

So I suppose that the issue is that skype is sending too large video, which jams the network and results in stuck call. I went thru skype settings and I cannot find anywhere video size settings. I also don't know how to set-up video size in v4l which is underneath skype.

So how could I make skype sending smaller video?
