can not play a video when qquickwidget(gstreamer sink qml) is added into a qgraphicsscene

[JoeCFD]

No issues to display a video with qquickwidget alone.

the implementation is here.

But no video if qquickwidget is added into a qgraphicsscene. Anyone has the same issue?

Hi,

Sorry not answer but why not use a QGraphicsVideoItem ?

[JoeCFD]

@SGaist I have a customized gstreamer pipeline and it needs only a gstreamer sink with a qt display widget.
I am not sure if I can add QGraphicsVideoItem to the sink. But I will try it. Thanks.

@JoeCFD Just checked the doc of gstreamer qmlglsink element and it requires QQuickItem. QGraphicsVideoItem will not work.
