that looks very interesting .... that means pd can get that position also.
A few improvements to the way I was doing it, a bit more info about omxplayer. I
should be able to simplify the connection and do a bit more within the external,
then make a master and slave version of the external.
will certainly look into it further, the omxplayer code has been a bit daunting
so I stayed with using what I knew was available in the standard omxplayer
first, to at least get that running. That is done, so I'll push it a bit further.

they have more interface details, so that is useful too.

I haven't gone down the higher level options, mostly because I also want to add
more low level stuff ... I have a basic player which I can map, do alpha layers
etc but it is very limited re codecs and containers etc, and am hoping
eventually to get something .
But maybe GStreamer is a better option for that?? I am not at all familiar with it.
I'll post my work-in-progress stuff and have a look at your github in the next
couple of days.
