[Arm-netbook] Allwinner A10/A13 Video Decoder Reverse engineered

[Ken Phillis Jr]

This is one of the methods, and there is another open source solutions for
OMX that has very similar features to what is seen in android...

Bellagio OpenMAX IL : http://omxil.sourceforge.net/
Bellagio OpenMAX IL Components:
http://sourceforge.net/p/omxil/components/ci/master/tree/

NOTE: Bellagio is known to work with XBMC, but some modifications to the
source is required to be able to make the encoders work.

Similarly...
Gstreamer OpenMAX support: http://freedesktop.org/wiki/GstOpenMAX/
gst-omx plugin: http://cgit.freedesktop.org/gstreamer/gst-omx/
gst-openmax plugin ( deprecated):
http://cgit.freedesktop.org/gstreamer/gst-openmax/

Also, it's important to note what is done with the Ubuntu support for Nexus
7...
