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

I have setup a video upload for my website with Perl. However, I want to extract an icon to represent each video. Is there a way to construct a Perl script to do the job? For example, extract a jpg or gif from a wmv file.

    mplayer does it,

Any suggestions? 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

      Zentara, My environment Perl in Windows. It is not Linux. Seems like the command are using Linux. I do need the find a way to run from Perl. Thanks,
        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

    You might also want to take a look at VideoLAN. They have a Win32 client that I have used successfully on a number of different systems.
