This input file really is vfr (variable frame rate),
our mov muxer requires constant frame rate, so the
default action is to do something stupid, but a
warning is shown that something is wrong with the
framerate, indicating you should either specify a
framerate with "-r" or insert the fps filter.
(The fps filter has its own shortcomings, I suggest
avconv silently drops and duplicates frames, I am
not completely convinced that this is much better:
If people disagree, I will open a ticket.
