Re: Which codec is required?

Where can I find the format for the different file types? If I at least had
that much I could parse apart the file.....

Exactly, which is why I was mentioning the file extension. That is always
the first filter in terms of identifying the media type. It narrows it
down to one or a few possibles. After that, you need to read the bits of
the file itself, and that means that you have to know the byte order of
the file format.

UJ,
Depending on the type of media, you will probably have to find or write
code
that parses the media headers. For example, an AVI file extension can be
anything from straight Windows uncompressed AVI video to DIVX.

Any ideas how to do this?

(I don't want them to download codec - I just want to use the codecs I
have
on the machine already.)

TIA - Jeff.
