Package-level declarations

The MediaSource interface of the Media Source Extensions API represents a source of media data for an HTMLMediaElement object. A MediaSource object can be attached to a HTMLMediaElement to be played in the user agent.

The MediaSourceHandle interface of the Media Source Extensions API is a proxy for a MediaSource that can be transferred from a dedicated worker back to the main thread and attached to a media element via its HTMLMediaElement.srcObject property. MediaSource objects are not transferable because they are event targets, hence the need for MediaSourceHandles.

The SourceBufferList interface represents a simple container list for multiple SourceBuffer objects.
