I've been playing around with Qt5 now for a few weeks, and my interest is especially in the new MultiMedia APIs. For 2 reasons, first, over 10 years ago I programmed my own simple MP3 Player with MFC and FMOD for the playback. Which I could recode now in Qt5, as its offering Media playback. Phonon did offer this in Qt4 already, but I never did take a closer look at Phonon. And secondly, because I'd like to use the Qt Multimedia APIs to build my own video recording application, as I couldn't find one for the last conference, and hence we screwed up that part last time.
