[jitsi-dev] Jitsi displays black screen for Webcam device preview


When selecting in the options preview a webcam as a video capture device
I'm getting a black screen screen. I tried debugging but no error shows up
in the java code. It seems related to the native code.
Could you please advise.
It is reproduced with windows 7 32bits and windows 2008 R2 64bits using
jitsi *2.2.4603.9615 and java 7 update 25 32bits *


*Thanks in advance*
