Where are the OpenMAX api in jogamp ?

Hi all.

I'm looking for resources about OpenMAX API in jogamp.
I don't found anything about it in the forum.

Where is OpenMAX in jogamp ?

In Jogl ?
In Joal ?
In Jocl ?

After few hours of research, I've found a commit using "com.jogamp.openmax" package. But I can't find it in actual source/javadoc.

I'm afraid to be really stupid, because "OpenMAX API" is written in the very first page of the site ...

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.

Thank you Xerxes for managing this ..

Yes, it would be nice to reanimate the OMX media implementation.
As Xerxes pointed out, Raspberry Pi might have a full OMX IL impl.
we may be able to use. We have to see whether we solve the stream
deplexer problem, if it's not supported by the OMX implementation.
Other platforms are welcome as well - but I don't know of any which
supports OMX properly.
