I just downloaded the Qt 4.4 opensource in order to experiment with the new features. Phonon and QWebkit are great... especially when paired with the graphics view!
That being said I noticed a few issues with phonon (video) on the graphics view. (note: I just used the mediaplayer qt demo with a qgraphicsproxywidget) On my windows machine it works great with .wmv and .mov types, probably quite a few others. But I noticed that divx and xvid videos would not work at all UNLESS we were not on the graphics view; that is, just as a windowed widget, then it worked fine. In fact when on the graphics view, it "thought" it was ok and seemed to be playing (audio worked and the video dimensions were correct) but the video area was just black.
Anyone else notice this or know anything about it OR know that I'm completely wrong.
