Yep, and in many cases the frontend ones too when a single shared store
is used for all the backends.

AFAIC there are two cases where it takes a long time: when the file is
empty and also when the keyframe map is broken/missing. The first could
be made faster by just failing quickly if the file is empty or doesn't
exist, and the second by just capturing the first frame if there is
a problem with the keyframe map. I'll fix these Monday/Tuesday night.
