Sorry for the lack of extensive infos...

Live-video and movie support is still in place. (I did not touch these 
parts of the plugin). I refactored only the reading and writing of 
images, so that the reading from files and streams, writing to streams 
and files use the same code-path. Less error-prone in my eyes. The 
functionality to read from and write to streams is new. I abandonded 
QTTexture because of it's clunky code, and because most of the code was 
not used.

The new class QTImportExport.h/.cpp was part of my own code since two 
months now and is working in OS X and Windows without a problem.

My tests on os x:

osgviewer --image

osgviewer cow.osg
osgmovie /Users/stephan/Desktop/madonna_4minutes.mov
osgmovie 0:0.live (for live-video)

all worked without a problem. I did even code a small example using 
boost and asio serving the current rendered frame via http to test the 
writing-to-stream-functionality.

I did some tests on windows, (reading images and playing movies) and 
averything works as expected.

cheers,
Stephan
