The vikiiii solutions works, but I found :

• It still required a bit of work to get everything running on my desktop. (download the dll, extract the code, browse files...)
• We have no clue of the constants (like "BitRate") available

I created a repository on github https://github.com/clun/movies-metadata to have everything in the same place. Just run mvn:test on the sample project to get informations on samples MP4, OGG, AVI, FLV, WEBM and MKV.

Here the sample code of the test :

  MovieMetadata movieMedataData = new MovieMetadata("./src/test/resources/small.mkv");
    movieMedataData.get(General.FORMAT);
    movieMedataData.get(Video.DURATION_STRING);
    movieMedataData.get(Video.WIDTH_STRING);
    movieMedataData.get(Video.HEIGHT_STRING);
    movieMedataData.get(Video.BITRATE_STRING);
    movieMedataData.get(Audio.COMPRESSION_RATIO);
