Can I integrate DEE with 3rd party tools or software?

The Dolby Encoding Engine offers a set of batch processing functionalities as well as replaceable plug-ins for multiple processing blocks.

What does CLI based architecture mean?

The Dolby Encoding Engine package includes stand-alone CLI tools. Audio and Video Encoding workflows can be designed by running these CLI tools in the necessary order.

I have been using XML-based workflow. I realized XML-based workflow is obsolete. What should I do? 

Dolby Encoding Engine v5.7.0 is the last release that supports the XML interface. Customers who are currently using an XML-based workflow should migrate to the Command-Line interface tools. Information on the command-line interface tools can be found in the Dolby Encoding Engine documentation. For questions, please contact dee-support@dolby.com.
