Unified Packager

Unified Packager provides fast and easy packaging for all Adaptive Bitrate (ABR) formats.

Schematically this looks like the following:

(mp4) files --> packager --> hds|hls|hss|dash (files)
                                    |
                                 storage

The following sections document how to package content for Unified Origin (USP), HTTP Smooth Streaming (HSS), HTTP Dynamic Streaming (HDS), HTTP Live Streaming (HLS) and MPEG-DASH.
