This patch has been tested using an i.MX6Q SabreLite (nitrogen6x config) along
with the usual Tears of Steel movie in 1080p:
http://media.xiph.org/mango/tears_of_steel_1080p.webm

Below are the commands used to test the different sinks:

$ gst-launch-1.0 playbin uri=file:///root/tears_of_steel_1080p.webm
$ gst-launch-1.0 filesrc location=/root/tears_of_steel_1080p.webm ! \
matroskademux ! imxvpudec ! imxipusink
$ gst-launch-1.0 filesrc location=/root/tears_of_steel_1080p.webm ! \
matroskademux ! imxvpudec ! imxeglvivsink

The toolchain used was the Sourcery CodeBench 2014.05. The video above also
requires the following extra configuration in order to demux the content:
BR2_PACKAGE_GST1_PLUGINS_GOOD=y
BR2_PACKAGE_GST1_PLUGINS_GOOD_PLUGIN_MATROSKA=y 

I'm not fond of all the dependencies of this  package but I couldn't seem to
find a way to do it differently. A try has been made to select the Vivante
package automatically but it requires doing a select of
BR2_PACKAGE_FREESCALE_IMX_PLATFORM_IMX6Q which doesn't work. Let me know
if you'd like another mechanism to be able to select this plugin.

Thanks,
Gary
