On Windows 10, I don't get a segfault. I do see a warning in the command
prompt.

QQuickWidget cannot be used as a native child widget. Consider setting
Qt::AA_DontCreateNativeWidgetSiblings

&gt; Hi,<br>
&gt;<br>
&gt; It appears that using a QVideoWidget and a QQuickWidget in the same PyQt5 \
application causes a segmentation fault on macOS.<br> &gt;<br>
&gt; The issue happens when a MediaPlayer connected to the QVideoWidget plays the \
video with mediaPlayer.play().<br> &gt; This seems to affect at least PyQt5 with \
Python 3.6.2, 3.6.1, and 3.5.3 on macOS 10.12. Both QVideoWidget and QuickWidget work \
fine when used separately, which makes me think this could be either a Qt or PyQt \
bug.<br> &gt;<br>
&gt; Attached is a small test code that demonstrates the problem as well as a core \
dump.<br> &gt; This issue only affects macOS as the previous code runes fine on \
Windows and Linux<br> &gt;<br>
&gt; Any help would be appreciated.<br>
<br>
</span>Seems to work fine for me.<br>
<br>
Phil<br>
