Hi, recently I installed LinuxMint KDE NADIA 64bits and I have the same problem, It's a laptop ASUS K50ij. In all different solutions found here in forums are for precedents version, and like @mauricep, I have the same output, the same with v4l2convert. I verified the actual paths for these libs in the command line, and always the same problem. With all other software the webcam works fine, It's only with Skype (ver 4.1 from repos).
In my case is not my laptop, is of a friend that finally accept to take the freedom of Linux world, but sadly with this problem she's not so convinced
, If I don't find solution for the next week i'll need to re-install Windows in the laptop (dual boot
), only to take skype working "normally".
