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.
