This is part of a larger project - changing to PyQt5 is probably not a
possibility.<br>
<br>
Maybe I should add:<br>
Everything is fine on the machines of other colleagues, while things go
wrong on my and on a second machine.<br>
I checked though that all machines are running the same python & pyqt
versions and they all are windows 7...<br>

causes python to crash</font>
<br>
<br><font size=2 face="sans-serif">Hello,</font><font size=2 face="Verdana"><br>
</font><font size=2 face="sans-serif"><br>
I'm having an issue using the Phonon VideoPlayer.<br>
Loading or starting to play a video file causes the python executable to
crash, leaving me only with a windows dialog saying that "python.exe
has stopped working".</font><font size=2 face="Verdana"><br>
</font><font size=2 face="sans-serif"><br>
I've boiled it down to the following,minimalistic example:</font><font size=2 face="Verdana"><br>
</font><font size=2 face="Courier New"><br>

This is on a Windows 7 64bit System using the portable python distribution:</font><font size=2 color=blue face="Verdana"><u><br>

</u></font></a><font size=2 face="sans-serif"><br>
I tried this with PyQt versions from 4.9.6, 4.10.4 to the latest as of
yesterday using "normal" pythoninstallations as well, without
any success.</font><font size=2 face="Verdana"> </font><font size=2 face="sans-serif"><br>
The video file should be available on any windows 7 installation.</font><font size=2 face="Verdana"><br>
</font><font size=2 face="sans-serif"><br>
Remarkably, all the Phonon examplesincluded in PyQt are working just fine
- though no Video example is included therein.</font><font size=2 face="Verdana"><br>
</font><font size=2 face="sans-serif"><br>
Any hints on where to start looking for the issue here?</font><font size=2 face="Verdana"><br>
