Is there a way to tell ffmpeg to collect N frames of video and output one

and that results in N JPGs. I suppose I could have a second ffmpeg
command that averages those 10 JPGs, but can this all be done in one
pass?
Maybe, but why? First off, you won't still have the original images if you
decide to process it differently later. Second, it just makes for a more
complicated command and thus more prone to being wrong :).
There are places where doing a lot in a single pipeline makes sense,I don't
think this is one of them.
