libQt5Multimedia - gstreamer fails

Mon Oct 28, 2013 9:14 pm

I am trying to play an audio file with qtmultimedia module.
But when I launch my application I see gstreamer error in console "GStreamer-CRITICAL **: gst_object_ref: assertion `object != NULL' failed." and when i click on audio file to play it nothing happens.

I also compiled example multimedia applications from qt5 examples folder (I tried both - cross-compiling on my laptop and compiling on RasPi), but the result is the same "GStreamer-CRITICAL **: gst_object_ref: assertion `object != NULL' failed."

I am using Qt5 and gstreamer libraries from twolife.be/raspbian repo

I have no idea what to do.
Can anybody help me please?

You can install this package
sudo apt-get install libqt5multimedia5
sudo apt-get install libqt5multimedia5-plugins

sudo apt-get install gstreamer1.0

Return to “C/C++”
