Wow, did using OMX straight off work on this one? Or are you running VLC 
as root? (Normally the OMX driver requires access to /dev entries that 
only the mediaserver can access.) Yesterday you said you enabled building 
libiomx-kk (which would be the right way to solve this), did it work 
better or worse with that compared with using OMX directly?
