This software is intended as a reference that can be customized to provide a reference for several use cases for live DASH distribution.
It uses VoD content in live profile as a start, and modifies the MPD and the media segments to provide a live source. All modifications are made on the fly, which allows for many different options as well as accurate timing testing.
The tool is written in Python3 and runs using using wsgi. There is a reference instance running on AWS at https://livesim.dashif.org, but you can also run it on your own server.
Low-delay DASH is also supported.
