hi all,i' working on phonon mediaplayer example in qt demos.
i use Microsoft Visual Studio 2005 and qt 4.4.2.0 on Windows XP.
i didn't install any backend, so i use the default one (must be directshow).
i can compile and build the project.
when i run the demo, i can play some videos, but in some videos (for example
384x288 avi file, video codec : Nero Video Decoder, i can play it with
windows media player) i get the following two error dialogs.
any help can be useful, thanks a lot...
