When you place a call your video won't be sent , you can still see your cam's preview on the call window but there's a black screen on the receiver's one .
I think there's something wrong with video in builds made starting since 15th january, last working on my system is number 5029.
I tested builds starting 5036 to 5044 (the most recent one ) and all has that problem .
I made some tries on online sip servers and also on my lan trying to decrease the quality of video (both bitrate fields in video settings ) but i have the same result.
