Filespec libraries?

[spamalam]

I am writing a java applicaiton for managing collections. One problem I'm having is the reading of filespecs of video and how best to do that, i know there's a multitude of existing programs dedicated to just doing that, but I've been unable to find a java library for handling video.

So that leaves coding a parser myself, which is a project in itself and will be required to work with a multitude of formats, specifications and details for the files, or alternatively and probably wiser, use JNative to use an existing applications libraries and let it do the leg work.

I was wondering if anyone had done this task before, or even if not could recommend a native library that handles the reading of multimedia files. Support for as many codecs, containers and bits of information as possible (the usual, codec, resolution, etc. but also the number of frames(!!), bpp, b-frames, i-frames, etc.). I know MediaInfo.dll supports basic file details for a number of containers, but I ideally want a project that has .dll and the linux counterpart available so the program is portable, as well as support for a lot of the more advanced details of video files. The JNative library supports using native libraries for several operating systems.

I figure you guys will be the best people to pose such a question to.

Thanks :)
