[Qt-interest] Play videos in Qt

[Mike Inman]

My point on cross-platform-ness of Phonon was that the content (actual 
video files) still need translating from one platform to the next, even 
if using the lowest common denominator of player features, there's still 
the problem of finding universally playable video formats.

VLC runs on all (of the major) platforms,  accesses a wide variety of 
video formats on all of those platforms, and has a pretty good feature 
set, which is why I'd like to see it "grafted" in behind Phonon instead 
of the patchwork quilt I'm currently seeing.  I suppose the GPL might be 
an issue, unless there is a way for Phonon to access VLC which does not 
offend the GPL.
