Abstract
In this short demo paper, we introduce godash 2.0 godash is a headless HTTP adaptive streaming (HAS) video streaming platform written in the Google programming language GO. godash has been extensively rewritten for this release so as to provide ease of use, and a host of new features. godash includes options for eight different state of the art adaptive algorithms, five HAS profiles, four video codecs, the ability to stream audio and video segments, two transport protocols, real-time output from five Quality of Experience (QoE) models, as well as a collaborative framework for the evaluation of cooperative HAS streaming. godash also comes complete with its own testbed framework known as godashbed. godashbed uses a virtual environment to serve video content locally (which allows setting security certificates) through the Mininet virtual emulation tool. godashbed has options for large scale evaluation of HAS streaming using 4G/5G bandwidth traces, various modes of background traffic, and a choice of web server, namely: Web Server Gateway Interface (WSGI) and Asynchronous Server Gateway Interface (ASGI). In this manner, godash provides a framework for rapid deployment and testing of new HAS algorithms, QoE models and transport protocols.
