[Libav-user] VFR and CFR and libav

Let's say I have an input video (AVI format) that is vfr, and I write
a libav application that steps through each frame in the video and
does something: maybe I write that frame to a file on disk.  Will
I have vfr-problems where the libav is duplicating frames, or removing
frames (behind the scenes) in order to make it CFR?  Does libav
do things like that?  If so, can I turn it off?
Also, and this probably isn't a libav question, but how can I tell
if my input AVI file is vfr or cfr?
