I bought a webcam to sykpe with my mother and sister who are living far away.
But when i start skypeing with one of they the video output on my system is flickering blue (after enabling video-chat).
On the other side my partie can see me good and there are no problems.
So i testet it on Ubuntu MATE 16.10. There it works fine, no problems.
I installed Skype via Ubuntu MATEs Software Boutique
Sorry to say but if your webcam works fine w/ other softwares then it’s for sure skype that is the problem.
If you R-E-A-L-L-Y are required to use skype, i would advise into deploying a windoze machine under virtualbox and/or notifying m$ (but that’s probably not give any real results in the short and medium time frame).
As usual, what happens if you boot using another distro in LIVE mode, install skype and give that a go?
Another thing I would suspect (if it works fine on another distro) would be your video driver but we’re going far now.
