So I gave this a more concerted effort.
gst utterly and stubbornly refused to recognise anything in the plugins directory.
so I had a look around in /usr/lib and sure enough there is a folder called gst-plugins however it also is not serviced seemingly by default.
So... final solution - just dump it all the gst root dir and throw gst-inspect at it. with some debugging voodoo.
[root@kindle games]#
strace -fF -o /mnt/us/gst-strace gst-inspect libgsteink.so --g
st-debug="*:7" 2> /mnt/us/gst-inspect-debug-eink2.txt
The output is eye-bending - this is a fixed-up slice

that's just from the /mnt/us/gst-inspect-debug-eink2.txt, I guess I should figure out how the "licensing" works then...
also there is no /usr/libexec/gstreamer-0.10/ folder on the device. so
gst-plugin-scanner obviously can't live there...
I DO actually have a version of it though...
so I'll copy that across and see what happens...
[root@kindle libexec]#
finder gst-plugin-scanner
(finder is just my "find" shell script)
/mnt/us/usr/libexec/gstreamer-0.10/gst-plugin-scanner

Bit of an extra test:
Trying it the old fashioned way gives us:

Which plays the sound fine. but obviously the video component is missing
Sigh. ah well gave it a go : ) again
at least I managed to get the registry to accept and update the presence of the ffmpeg and video stuff.
Perhaps a solution will present itself with these new tools in the medium term for those of us who just can't get this to work : )
