The source code and built files are available from the Sourceforge.net Jffmpeg download page.
Jffmpeg has two files:
The .jar file should be included on the classpath when JMF is in use.See the JMF documentation on how to add codecs to the JMF classpath. The libjffmpeg.so native library is optional, but supports a wider range of formats with higher performance.
The Java Media Framework comes with a tool JMFRegistry to add codecs. It is available from the jmf.jar file, or from the "Preferences..." menu option in JMStudio. Alternatively type "java JMFRegistry" from the commandline.
Under the "Mime Types" tab register the following MIME types:

Don't forget to commit each change.
The JFFMPEG project contains code under three different licenses:
Classes under the GPL license implement the GPLLicense interface, and are clearly marked in the source code. The following codecs are licensed under the GPL license:
The GPL classes may be separated from the rest of JFFMPEG by simply removing all classes that implement the GPLLicense interface.
The majority of JFFMPEG is under an LGPL license. This include the following:
The LGPL code may be shipped with GPL code.
The Ogg Vorbis demultiplexer and codec is a separate codebase for licensing purposes. See the Ogg Vorbis COPYING file for details. The Ogg Vorbis code may be shipped separately under its BSD style license. Similarly the rest of JFFMPEG can be shipped separately under the appropriate license terms.
Ogg Vorbis and the rest of JFFMPEG cannot be shipped under a single license, they are two different codebases licensed under two different licenses.
Note that this is a legal, not technical issue. If in doubt consult a lawyer.
