Getting Started Guide

# Rich Media

Media Server allows you to process and analyze images, video, and audio files.

You can use this component in combination with the Knowledge Discovery text processing components. For example, you might want to use Media Server in your NiFi ingest or CFS workflow to transcribe audio files that you extract from a repository, and then index the text output into the Content component.

You can also use Media Server independently of other Knowledge Discovery components for stand-alone media processing. For example, you might use it for face recognition or number-plate recondition from video files. Media Server can process individual files, or continuous data streams.

In NiFi Ingest, you can include one of the Media Server processors in your NiFi installation. The MediaAnalysis processor connects to a Media Server instance, which you set up and configure separately from NiFi. You then configure the NiFi process to send files to Media Server for processing. Alternatively, you can use the Ingest Media Processors, which run media analysis as part of the NiFi process.

To use Media Server with CFS, you must configure CFS with details of the Media Server component to use for processing. If necessary, you can use these components with a DAH for load-balancing and failover.
