OGV video cannot be played with qml using qt multimedia

The user made sure the aiur part of the gstreamer (0.1) is disabled (by editing /usr/share/aiur_registry.arm11.cf). The user can play ogv-video with this command:

gst-launch playbin uri="file:///home/root/out.ogv"

The user however cannot see a thing on the screen after launching mediaplayer from her application.

The user can watch from her application any *.mp4 videos.

Steps to reproduce:

1. open adb shell, modify configuration file mentioned in description and run gst-launch as suggested above. Make sure everything works without an error.
2. Run application attached as it is and click on the screen. You should see the video (first one is mp4).
3. Open the main.qml file and comment mp4 video source and uncomment ogv video source
4. Compile and run application. Instead of video the black screen will be shown.

If you have some doubts the video is playable, try to watch it with gst-launch as suggested above.

All videos can be found in demo attached.
