I am currently working on an i.MX6 SoC-based system... I've just built Qt 5.3.2 (through Yocto) configuring it for using gstreamer 1.0 as backend...
The compilation completes successfully, but unluckily I am not able to play HTML5 video from QWebKit...
Looking at the console output of my application (a simple QML-based application showing a WebView full-screen) I see the messages from gstreamer (so I think that the library is initialized and working)...
QML debugging is enabled. Only use this in a safe environment.
QEglFSImx6Hooks will set environment variable FB_MULTI_BUFFER=2 to enable double
buffering and vsync.
If this is not desired, you can override this via: export QT_EGLFS_IMX6_NO_FB_M
ULTI_BUFFER=1

As you can see, gstreamer also reports the correct duration (length) of the video resource, but then I am not able to start the playback... The "play" button shown on screen is "greyed" and the duration of the media is reported as "00:00"... Even clicking on the "track bar" does not produce any results...
A screenshot of what is appearing on screen here follows:
Any ideas?
