VBScript to get header info from FLV (flash video) files

    VBScript to get header info from FLV (flash video) files

    Hi,
    I've just started playing with some FLVs I've downloaded. Looking at them
    with a hex editor, it appears they start with a header that has info about
    them, such as play time, whether they are audio, video, or both, etc.

    I've looked at Adobe's manual on FLVs, video_file_format_spec_v9.pdf, and it
    appears relatively easy to get to the metadata I'm looking for. I'd rather
    not reinvent the wheel here, so I'm hoping someone will share a VBScript
    that decodes this info, or a link to such a script.

    This one works for .jpg and .mp3 files. May it works for .flv files too:

    Thanks, Pegasus

    I didn't even think about using the folder view options to turn on those
    column in a folder window. But when I did, nothing showed up. Maybe WXP
    SP2 doesn't know how to get this info from adobe flash video files. I'll
    bet Windows 7 displays the info I want for flash files, though.

    Using your script, I get similar results: no data for properties 9 and up.

    A moment ago I ran my script on a WinXP PC against an .mp3 file and got an
    output for fields 1-10, 12, 16-23, 32-34. The meaning of the fields was
    largely different from what the script says. It appears that different types
    of multi-media files use the same header but with different field meanings.

    I tried some more googleing and found this: http://www.buraks.com/flvmdi/
    It is a command line tool that creates an XML output with all the metadata:
