Mediacast Producer

Version 0.1 Copyright 2011-2017 Stephan Jorek

complements: Podcast Producer action task, version 2.0 Copyright 2006-2011 Apple, Inc.

The Mediacast Producer action tasks integrate several popular tools as “ffmpeg” or ”VLC” in Apple's Podcast Producer. This allows the automatic production of media-file formats that go far beyond MP4.
