The input video has 30fps, so this is not an optimal command line / 
the r option should not be needed.
(Does -vsync 1 really make a difference?)

Note that above command line does something else than the one 
you posted that works fine here, I am curious why it does not 
work for you, if you (also) want to find out why, please post 
the complete, uncut console output of your failing command.

Merry Christmas, Carl Eugen
