Validate multimedia files with java

[Jerome]

Hi there,

I want to build a movie repository with many different format for one extract,
but I would like to be sure that admin users will put the correct data regarding
file format, rate, ...
Is there a way to read a video (windows media, real player) or audio file
with a java class and get all these data ?

Thanks a lot in advance
Jerome

Jerome,

This can usually be accomplished by reading the first few bytes of the file
and verifying that it meets the requirements of a format that you want to
support. You can do this using standard Java io classes. I have done this
many times to verify the format of image files.

I'm not sure what the format of the files types are that you specified, but
usually there is a header at the beginning of the file that can be used to
determine it's type. See the websites for the formats you want to support.
For Windows Media, I suggest msdn.microsoft.com

Hope this helps,

Rob
