Gem won't (shan't) touch any settings of the device if it can help it.
so setting the framerate before you start Gem should get you somewhere.

furthermore, it should be possible to change some properties of the
camera even while Gem is capturing.

in the case of guvcview this might not work due to guvcview (which
tries to also _capture_ images and fails doing so), but tools that
only set properties should work ok.
i'd recomment something simple like v4l2-ctl (on debian this is
available in the v4l-utils package)

$ v4l2-ctl -d /dev/video0 -p 120

nevertheless, setting the framerate is currently really missing in
Gem's v4l2 backend. please file a feature-request (for Gem!).
