MediaStream
The MediaStream interface of the Media Capture and Streams API represents a stream of media content. A stream consists of several tracks, such as video or audio tracks. Each track is specified as an instance of MediaStreamTrack.
Properties
The active read-only property of the MediaStream interface returns a Boolean value which is true if the stream is currently active; otherwise, it returns false. A stream is considered active if at least one of its MediaStreamTracks does not have its property MediaStreamTrack.readyState set to ended. Once every track has ended, the stream's active property becomes false.
Functions
The addTrack() method of the MediaStream interface adds a new track to the stream. The track is specified as a parameter of type MediaStreamTrack.
The clone() method of the MediaStream interface creates a duplicate of the MediaStream. This new MediaStream object has a new unique id and contains clones of every MediaStreamTrack contained by the MediaStream on which clone() was called.
The getAudioTracks() method of the MediaStream interface returns a sequence that represents all the MediaStreamTrack objects in this stream's track set where MediaStreamTrack.kind is audio.
The getTrackById() method of the MediaStream interface returns a MediaStreamTrack object representing the track with the specified ID string. If there is no track with the specified ID, this method returns null.
The getTracks() method of the MediaStream interface returns a sequence that represents all the MediaStreamTrack objects in this stream's track set, regardless of MediaStreamTrack.kind.
The getVideoTracks() method of the MediaStream interface returns a sequence of MediaStreamTrack objects representing the video tracks in this stream.
The removeTrack() method of the MediaStream interface removes a MediaStreamTrack from a stream.
