ffmpeg output blank image files on CentOS 6.4

Question

0I am trying to capture thumbnail images from a video by using ffmpeg.

So I typed command like Below.

ffmpeg -i MyVideo.mp4 -s 480x270 -f image2 -vf fps=fps=1/600 thumb%03d.png

just like what ffmpeg official site suggested.

The length of MyVideo.mp4 is 01:46:03, So I expected total 10 images from it.

(because fps=fps=1/600 part means 10minute 1piece.)

But output is 12 pieces, and especially first one is broken.

When I check it's information in GUI, it says "failed to load information".

Please ask your FFmpeg command line questions on [SU], and don't forget to include the full, uncut console output. — slhck, Apr 19 '13 at 08:01

because fps=fps=1/600 part means 1minute 1piece.

This means 1/600 frames per second, or one frame every 600 seconds.

You probably want fps=fps=1/60
