I just tried your changes and I managed to make it work. I had to modify the code a bit to be able to compile it on my end. Also, the code as it is (from your fork) doesn't work on OS X (at least on my machine and my code) so I created a fork where I isolated the unix code from the windows one. Lazy method, I know... I just can't afford to spend time on modifying addons. I will look more into it after my project iteration.
Thanks again for writing the fix 
on OS X, the frames are recorder, but when I finalise the recording, the video file gets corrupted for some reason and I cannot play it
