Video doesn't get written in Ubuntu 16.04 #47

I noticed that the video doesn't get written in Ubuntu 16.04.1 LTS. OpenCV version is 2.4.9.1. Version 3 is not available in the normal repository. Only a header 5686 bytes long gets written.

It might be possible to bypass cv::VideoWriter by writing video with Qt Multimedia framework or GStreamer which is the backend of the multimedia framework and possibly also the backend of OpenCV.

This issue has been fixed in OpenCV 3.1.0: https://github.com/opencv/opencv/issues/5439

There are a few solutions:

use lossy/packed codec like H264 (but this option is not given to user)
install OpenCV 3.1.0
