This project is no longer maintained and new efforts are done in the livesim2 project instead.
The online service https://livesim.dashif.org on AWS is being stopped beginning of October 2023, and the DNS instead pointed to the new livesim2 service on Linode at https://livesim2.dashif.org.
The old AWS instance can currently (Oct. 4 2023) be reached at http://ec2-54-161-101-85.compute-1.amazonaws.com.
Please look at the new project and use livesim-content to set up your own test service.
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.
