QML playback test

I've built Qt 5.6 with gstreamer 1.0 support on Raspberry Pi B.
I've used gstreamer v1.7.2 with latest gst-omx.
Also I applied this patches:
https://bugzilla.gnome.org/show_bug.cgi?id=753886#c13
https://bugzilla.gnome.org/show_bug.cgi?id=760916

I tried to play 1080p video but framerate is very low (nearly 1 frame per 5
seconds).
During playback I noticed that omxh264dec thread consumes up to 60% CPU.

Although playback with "gst-launch-1.0 playbin uri=file:///<video>" has no
issues.

You can find QML file I used for tests in attachment.
