It does. Thanks.

However, I'm now even more confused ;-)

I've got it working by using the gstreamer recipe from 5.0.1 (I'm  
building under 4.0.1). However, bitbake -e still reports as above and  
I can't see ffmpeg in any context other than

RECIPE_STATUS_pn-gst-ffmpeg="red".

Still, it's working :-)
