[Qt-interest] VLC on Phonon

[Daniel França]

Hi, thanks for the answer.

My motivation is that it can simplify the maintenance and use of my app.
For example: Now if I use the default backends for Phonon it's using QT for
Mac, DirectShow for Windows (both for XP and Vista/7, I guess) and
GStreamer for Linux, so I've to care about the codecs installed in the host
pc, etc.
If I move to VLC it's present in all platforms and I can put the codecs in
my setup app, with no need to care about what codec is installed or not.

furthermore if I try to run wmv on Mac/QT, even using Flip4Mac isn't 100%
fine.
I've found the Phonon VLC KDE project:
https://projects.kde.org/projects/kdesupport/phonon
but there's no documentation and now I think it's only for KDE.
