[mythtv-theming] coverfile vs screenshot

So, I'm trying to work out how to do something similar.

I have a set of videos that didn't originate in recordings.  Well, they
actually did, but they're music videos, and I edited the show to break them
down into their component videos.  At the moment they show blank images in
the gallery view, and it is unlikely that they'll get metadata downloaded
unless I'm spectacularly lucky.  

What would be nice is to use screenshots for each.  What would be even
better is to be able to select the screenshot during playback - have a menu
item that lets you pause it and then say "set screenshot as coverfile" or
similar.  But actually, anything that worked would be OK - something that
gets a screenshot the same way as recorded programmes do would also be

I'm not sure whether this exists already, or whether it needs something
written.  I know I could write a script that uses ffmpeg or mencoder to
grab a screenshot, and I think I could probably pick where in the video to
get it from by just grabbing the current position in the video (assuming
you've watched it and then exited at a particular point - that must be
saved in the database somewhere).  And I think I saw an enhancement go up
that said people could build custom screenshot grabbers.   

But before I spend time trying to work out how to do all that, the question
is whether I'm on the right track, whether there's another way I'm not
thinking of, or whether there is something coming already that would
provide some sort of screen shot.
