In this talk, we discuss the details of a content-aware playback speed control (CAPSC) algorithm we developed for dash.js along with the metadata we defined to indicate the event densities in a given content. However, this mostly depends on the part of the audio/video content subject to the playback speed change. While adaptive playback generally works well, the artifacts due to the changes in the playback speed should preferably be unnoticeable to the viewers. This tool allows the streaming client to slow down the playback when there is a risk of stalling and increase the playback when there is no risk of stalling but the live latency is higher than desired. One of the best tools we have today to manage this trade-off is the adaptive playback speed control. Yet, these two factors work against each other and it is not trivial to strike the best trade-off between them. Latency should be low and stalls should not occur. There are two main factors that determine the viewer experience during the live streaming of sports: latency and stalls.
