Class VideoHelper

java.lang.Object

org.nuxeo.ecm.platform.video.VideoHelper

public class VideoHelper
extends Object

Helper class to factorize logic than can be either called from the UI or from core event listener.

If the need to evolve to make this further configurable (not just using the existing converter / commandline extensions points), we might want to turn this class into a full blown nuxeo service.
