[PyQt] Embedding MPlayer in a QWidget // painting problems

[Timothy W. Grove]

Thanks, I'm giving VLC a try and it seems to be working okay. Probably a 
question for the VLC forums (I'll copy a post there in a minute...), but 
I don't understand why I can't get autocropping to work. I'm using 
"""self.Instance = vlc.Instance("--no-audio", "--play-and-pause", 
"--autocrop") """ within my program, and I've tried using the same 
arguments on the command line but no joy. Should I be adding any other 
arguments to include this filter? I'm using the precompiled version of 
vlc.py which came with the Qt bindings; under Windows 7, PyQt4 and 
Python 3.2.

MPlayer was also working well embedded into a QWidget, only the 
background was destroyed in resizing when paused or stopped as described 
in my earlier posting below. I attempted also to take screenshots using 
QPixmap.grabWindow() and .grabWidget() but these only return an empty 
image. I'd still like to understand this behaviour if anyone has any 
ideas. Thanks.

Best regards,
Timothy Grove
