Problem loading video on OS X about cimg

[dtschump]

Works for me with the provided video file on Ubuntu Linux, using ffmpeg.
I cannot tell much about the issue. Maybe The OP should try to read his video with ffmpeg alone, to see if this works. And if it works, that could mean ffmpeg is not found by CImg (is it in the $PATH ?).
Does the bug happen with an older version of CImg maybe ?
There are many possibilities. The fact that it doesn't work with convert at the very end does not surprise me too much, but if ffmpeg is installed, I see no reasons why it couldn't handle the file.

Another solution would be to enable the OpenCV library when compiling CImg, as it can be used to read/write video files as well, in a more "native" way (without an external system call to ffmpeg). I've tried this solution too, to read the provided video, and it works well too.
