Before this patch the qmlplayer2 example application has crashed after I have
resized the application window several times. Before this patch I have wrote
the video frame data in the bind() method of the VideoMaterial class to the
OpenGL texture. I think this was too late and because of this the video frame
data pointer was already invalid.

I had to change the place at which time the video frame data was written to the
OpenGL texture. As soon as I got the video frame data I stored it in the OpenGL
texture. After this I didn't get any segmentation faults when resizing the
application window.
