[MPlayer-users] Using with webcam Genius Look 320s

[Stanislav_Egorov]

I've built linux kernel 2.6.29(vanilla), built sn9c20x(from Microdia),
insert it.

dmesg:

Linux video capture interface: v2.00
usbcore: registered new interface driver sn9c20x

And after run mplayer for testing it I see:

video0 -vo x11
mplayer: Symbol `rgb32to24' has different size in shared object,

What is the problem? Can somebody explain what happen? Maybe driver is
broken? Or v4l is broken?
