I have the ffmpeg command line I will need to perform the transcoding I require but can find no information about how to call it from the java application. My searches keep bringing me back to Xuggler, but since I need to transcode audio to AAC that does not seem to be an option as Xuggler have remove AAC trascoding due to license issues.

Look up the Java exec() method.
