Comment (by b_jonas):

 Replying to [comment:1 cehoyos]:
 > Looks like a duplicate of ticket #1578, please test {{{-vf fps}}}.

 I have tested with the following command.
 {{{
 ffmpeg -v 99 -report -r 30 -i lbl-%04d.png -vf fps=1 fps-%04d.png
 }}}

 This does not reproduce the bug, it gives apparently correct output.  The
 output has files named fps-0001.png to fps-00013.png, containing the
 following text: 0000, 0015, 0045, 0075, 0105, 0135, 0165, 0195, 0225,
 0255, 0285, 0315, 0345.
