Just to keep things in synced....
this bug connect with other one:
https://bugzilla.gnome.org/show_bug.cgi?id=627459

short description:
resubmitting frames make no sense especially if we know it is a duplicate
frame. New videorate was updated to make it possible for theoraenc count
dup/GAP frames and let encoder know how many granules should be produced for
oggmux. So, if for example, webcam drop frame rate to 1fps and default frame
rate is 30fps, theoraenc can produce valid stream without increasing cpu usage.
It mean: one frame in - one frame out, no need to recreate 29 frames and make
cpu beasy for no reason.
