DASH-IF livesim2 – a test ground for live DASH streaming - by Torbjörn Einarsson, Eyevinn Technology

Torbjörn Einarsson has a long background in video coding and transport. After leading video coding and protocol teams at Ericsson Research, he worked at the CTO offices of MobiTV and Edgeware before joining Eyevinn Technology as a consultant in January 2023. Streaming video has been a key area of his work for more than 20 years.

As part of establishing and understanding the timing complexities of DASH live streaming, Torbjörn developed the “dash-live-source-simulator” which was contributed to DASH-IF in 2015. Another much-used DASH-IF component is his “cea608.js” that is used in many players.

At the beginning of 2023, Torbjörn started a complete rewrite of the live source simulator to make it easier to use, cheaper to deploy, and make it more future proof. The result is “livesim2”.
