Wow, that could be just the ticket.

Josh, many (most?) media file-types have 'magic-numbers' at the
start (and sometimes also at the end), which identify them as
whatever type they are.
Have a look at http://en.wikipedia.org/wiki/Magic_number_(programming)
Best,

I am working on a handler to determine whether a file is a media
file. (for OS X and Windows)
First, I check if the file has a proper extension (.mov, .jpg,
etc.) if so, I assume the extension is correct (a leap of faith
perhaps)
Second, I try to get the OS X filetype from the detailed files.
Some movies properly list "Moov", some don't.
Third, was going to try loading the file into a Player or Image
object and see if there's an error, but many types of files will
load into those objects fine (like text files)
So, I'm wondering if anyone has any tips beyond these things...
