One thing that is wrong in your code is that you never call 
av_write_trailer(), which should be called before avio_close().

Also, there's no need for m_file in your code.  avformat handles the 
file for you.

Other things are hard to say, as you don't provide the code to the Image 
or cv::Mat classes.  You should provide a self-compilable example for us 
to help you.
