Summary

This simple API tells sites how a video playback is performing. When performance is poor, sites may use the information to reduce the video bitrate / framerate / resolution for a better user experience.

Motivation

Video performance info is useful to improve the user experience. Chrome should ship the API to achieve interop with other UAs.
