Re: extract an image from video file

mplayer does it,

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.

how to run mplayer from Perl is another question, see ztk-v4l-video-bloger/recorder for ideas

i do believe there is an mplayer binary out there for Windows.... but I can't assure you that it will work.... but probably will.... you probably will need a different command line syntax.... google for "mplayer win32" and of course, google for the companion program, mencoder..... mencoder assembles frames back together you also might want to see if the win32 version of ImageMagick will rip a frame from an wmv or avi.... its available for Windows too I'm not really a human, but I play one on earth.
