I am trying to play example qml video from qt5.5.1 in raspberry pi 2. I get the following error message.
I have installed gstreamer 0.10 ad gstreamer1.0 libraries by searching through google.
Please someone help about this error message.

you need also to install gst-plugins-good/ugly

Yeah I already installed gst plugins.Is any other dependency which is needed???

I have the following gstreamer plugins installed.

Where would be gstreamer plugins installed?
