The MediaSource object represents a source of media data for an HTMLMediaElement. It keeps track of the readyState for this source as well as a list of SourceBuffer objects that can be used to add media data to the presentation. MediaSource objects are created by the web application and then attached to an HTMLMediaElement. The application uses the SourceBuffer objects in sourceBuffers to add media data to this source. The HTMLMediaElement fetches this media data from the MediaSource object when it is needed during playback.
Each MediaSource object has a live seekable range variable that stores a normalized TimeRanges object. This variable is initialized to an empty TimeRanges object when the MediaSource object is created, is maintained by setLiveSeekableRange() and clearLiveSeekableRange(), and is used in HTMLMediaElement Extensions to modify HTMLMediaElement.seekable behavior.
