I am experiencing problems with phonon direct show backend on WinXP. Basically it doesn't work at all for me :) I've tried it with both 4.7.0 SDK and with version built from sources. In both cases phonon_ds94.dll is located in plugins/phonon_backend/ dir.

Here how I create video player:


vp = new Phonon::VideoPlayer(this);
...
vp->play(QUrl("..."));


And this is what I've got as output during debug run qt-creator:

Does anyone has any ideas?

It seems that it is a bug in Qt itself, which was introduced somewhere after 4.6.3. I've filled bugreport, everyone who has similair problem please go and vote http://bugreports.qt.nokia.com/browse/QTBUG-13062
