  Adaptive video streaming over HTTP is becoming omnipresent in our daily life.
In the past, dozens of research papers have proposed novel approaches to
address different aspects of adaptive streaming and a decent amount of player
implementations (commercial and open source) are available. However, state of
the art evaluations are sometimes superficial as many proposals only
investigate a certain aspect of the problem or focus on a specific platform -
player implementations used in actual services are rarely considered. HTML5 is
now available on many platforms and foster the deployment of adaptive media
streaming applications. We propose a common evaluation framework for adaptive
HTML5 players and demonstrate its applicability by evaluating eight different
players which are actually deployed in real-world services.
