Video is unavailable

Given any video, the GUI says the video is unavailable

Actually I don't remember anything about this project.
But you may check these to troubleshot:

• OpenCV version
• OpenCV file input
• OS file path separator

All in all, this problem can not be that hard to be resolved!

Will look into it.
