ultranerds has asked for the wisdom of the Perl Monks concerning the following question:

Hi,

I'm trying to automate the grabbing of a "screenshot" of a .flv movie, so we don't have to manually do this.

I'm on a UNIX server (with full root access).

Can anyone suggest an approach?

TIA!

Andy

    ffmpeg can do screen shots

    ffmpeg -i moviename.flv -f image2 -s 320x240 screenshot.jpg

    .... mplayer also works

mplayer -vo jpeg file.avi
(generates 1 JPEG per frame, plays all frames)

mplayer -vo jpeg -ss 1:23:45 -frames 20 file.avi
(-sseeks to 1 hour 23 minutes 45 seconds in file.avi, generates 20 JPE
+Gs
from the subsequent frames, quits)

"man mplayer" for more stuff, like skipping to the start of a DVD
chapter.

    Image::Magick also extracts and recombines videos.... google for "ImageMagick extract flv frames"
