Media Information Extractor for Java

Question

I need a media information extraction library (pure Java or JNI wrapper) that can handle common media formats. I primarily use it for video files and I need at least these information:

1. Video length (Runtime)
2. Video bitrate
3. Video framerate
4. Video format and codec
5. Video size (width X height)
6. Audio channels
7. Audio format
8. Audio bitrate and sampling rate

There are several libraries and tools around but I couldn't find for Java.

Answer 1

You don't need a framework for this stuff, for example AVI video container format has a 56 byte header containing all the relevant metadata. There's bunch of other formats on that site too, all of them seem to be quite trivial to implement.

Answer 2

Try Xuggler. Here's some Xuggler source code that queries a media file and prints out all sorts of useful meta-data.

Answer 3

Have you tried Java Media Framework API http://java.sun.com/javase/technologies/desktop/media/jmf/ but I am not sure if it will have enough support as Xuggle above which uses FFMpeg, the only advantage of using this would be cross platform support.
