It could be useful for other resources, too. However, the decodedFrames and the
droppedFrames are video-only as is the playbackJitter.

At one stage we were discussing creation of a playback metrics object that the
mediaElement could use. Is that what you want perf to work on?

Also something that may be of interest to explain the use case better: if you
right click on a YouTube video and select "show video info" you get these kinds
of quality of service metrics, too.
