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:
skype
LD_PRELOAD=/usr/lib32/libv4l/v4l1compat.so skype &
LD_PRELOAD=/usr/lib32/libv4lconvert.so.0 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?
