Quite a few releases ago of the nightly builds the video stopped working and would just display a black screen for the sending user - see attached. We tried a couple of different cameras and those built into laptops which we knew used to work but assumed a bug had crept in. We can see the preview ok but when we hide/show the preview it pops up on the left hand side whereby it originally appeared on the right hand side - is this correct?
We didn't make a note of the last nightly build whereby video worked (sorry we keep upgrading daily and moving forward) but hope you guys can fix this issue again restoring video. We have tested on Windows 7 Pro and Windows 8 Pro machines both with the same results.
If you need anything for me to help fix this issue then please don't hesitate to ask.
