File Sniffer Component ?

Hello there,
Before I go and construct one myself, are there any pre-made components that
will "sniff" a file header and tell me what it is ?
The types of file I am seeking are mp3, avi, mpg, flv, wmv and mov.
I would like to pass in a file and it tell me what type it is and if its a
valid header.
For example, I have an mp3 encoded with the LAME3.84 encoder, and doing a
google search it tells me that this encoder is broken somehow. This is quite
apparent as it plays distorted in WMP and my program as well.
Is there a component / routine that does this, or do I need to create it
myself ?
Regards
Anthoni

I don't know about any library but I have been using Get Type of File

(called GT2) found here : philip.helger.com/gt/program.php
The developer is a great hacker and will surely help you as he seems to
be Delphi fan.

Yogi do you have the functional interface for the Dlls as the only

documentation I can see is for the command line?
cheers, harrie.

This is actually pretty good and might be worth using. Depending if Yogi can

get a wrapper for the DLL's for GT2. If he can will wait until I can test
that, otherwise I will use this one.
Thanks

Yep me too looking for this. Dont want to have to call command line from my

program.
Failing this I will opt for MediaInfo.dll instead.
