OpenMAX was added to JOGL for use by the GLMediaPlayer. It got demonstrated back in 2008 running video decoding on the mobile  APX2500 (NV) and ES2.0 tegra1 device.

I chatted with sgothel and noxo about reviving/using the OMX implementation some month back:

20130206 22:09:15 <xranby> sgothel: is any of the jogamp demos using openmax nowdays?
20130206 22:09:40 <xranby> i am chatting with noxo on twitter trying to find any working OpenMAX java audio library
20130206 22:09:47 <sgothel> @XRanby: well .. yes, but I had to strip down OpenMAX impl. due to license issues
20130206 22:10:26 <xranby> sgothel: really? so the khronos royality free etc spec is all vapour?

20130206 22:12:49 <sgothel> and 1be7b5271ec1d08b6929a88dd811754d33d149de
20130206 22:13:30 <sgothel> it was using an NV extension for parsing multiplexed streams ..
20130206 22:13:36 <sgothel> this is not included in OMX :(
20130206 22:13:51 <sgothel> w/o .. it's sort of useless .. so we would need that back

If you want to work on using OpenMAX for the GLMediaPlayer then first change
jogl/src/jogl/classes/com/jogamp/opengl/util/av/GLMediaPlayerFactory.java
to instantiate a jogamp.opengl.util.av.impl.OMXGLMediaPlayer for your platform.
After that you need to find ways to do multiplexed streams on your hardware.
