I tested 'motion' on Wheezy yesterday. It detects motion and takes

Can anybody confirm that movie output works on Wheezy?
Yes.
One thing that may be a factor in my case is that my test webcam is
very slow. I am only getting one picture every 2 or 3 seconds when
motion is detected. I have framerate set to 2 fps. Maybe motion is
aware that my pics are too far apart in time and is deciding not to
combine them into a movie.
Any clues in the logs? 'top' may help find any bottlenecks. Note that
an older box will have problems with high frequency high resolution
images - especially with USB < 3. A work around that problem might be
any or all of:-
;reduce frequency of images
;reduce image resolution
;offload image processing to hardware
What sort of motion are you wanting to detect at 2 fps? A break-in by
Speedy Gonzales? ;p
Be careful or your motion directory will quickly fill with a huge amount
of pictures. I don't use the movie output version - though I've used it
in the past. I found it an unnecessary use of resources - it's trivial
to construct a movie from the relevant still images at a later date -
just ensure that you email those images off-site immediately after a
motion event is detected (if you're using motion for security purposes).
It may be relevant that while I do have the deb-multimedia.org
repository enabled on the Debian (Wheezy) systems that run motion, it's
pinned to give preference to debian repositories:-
$ cat /etc/apt/preferences.d/multimedia.pref
Package: *
Pin: origin *.deb-multimedia.org
Pin-Priority: 200
