[FFmpeg-user] thumbnail issues

Hi all,
   I am playing with a file where I want to extract thumbnails
periodically. However I see that the outputs are not exactly periodic, but

My command is
ffmpeg -i abc.flv -f image2 -r 1/6 -s 200x100 'thumb%d.jpg'

abc.flv is 20 seconds long, however it produces 6 thumbnails (not one every
6 seconds apart), and they are concentrated at the first part of the video.

Any ideas why this might be happening ?
