Overview

The media benchmarking harness consists of the media story set, and the media metric. Those two elements are brought together by the media benchmark.

The media story set is a set webpages along with instructions for automating interactions with them. The media story set consists of two types of stories: src= stories and MSE stories. The src= stories simply run a saved media file from start to end. The MSE stories directly call various MSE APIs.

The media metric takes in a trace file and computes various metrics such as seek time and time to play using the trace events.
