RE: How to Determine Codec for Media?

>want to do the same thing that qt player does – alert the user when a codec is missing so the user doesn’t blame

> the player!

From what I know QT Player on Windows at version 7 of QuickTime is using the new Apple QuickTime ActiveX control for its functionality. So maybe it is possible to get extra info on why the movie doesn't open (you still have to try and open it though programmatically I suppose and check the error result)
 
An idea might be to use a COM/OLE calls interceptor (one that wraps arround a COM library and logs all method calls to its objects and all callbacks from them) to find out how it's done by QT Player (there might be such a product arround). Else can try using a debugger or disassembler (I suggest IDA [Interactive Disassembler] Pro)
 
Have you searched the list archive (and/or googled) on this? A very good searching tool (uses many search engines) is Copernic Agent (www.copernic.com), it even has a free basic version. Also Copernic Meta is nice cause you can define more search engines yourself using a query URL format string
 
cheers,
George
