How the MPEG-DASH segmenter properties work

The audio and video packets from a live encoder enter Wowza Streaming Engine and are segmented into chunks based on time. The duration of each segment is controlled by the mpegdashSegmentDurationTarget property. Segments are added to the available segment list as they’re created. The maximum number of items stored in the list is controlled by the mpegdashMaxSegmentCount property. When an MPEG-DASH client requests a stream, Wowza Streaming Engine provides a manifest that contains the n most recently added segments. The number of items returned in the manifest, n , is controlled by the mpegdashPlaylistSegmentCount property.
