This feature is obsolete. Although it may still work in some browsers, its use is discouraged since it could be removed at any time. Try to avoid using it.

The LocalMediaStream interface was part of the Media Capture and Streams API, representing a stream of data being generated locally (such as by getUserMedia(). However, getUserMedia() now returns a MediaStream instead, and this interface has been removed from the specification.

The primary reason for this interface to exist was to add a stop() method to its MediaStream parent interface. However, control over playback of media has been moved to the individual MediaStreamTrack objects, so this is no longer necessary. Instead, media is stopped by calling MediaStreamTrack.stop() on each track that needs to be stopped. The example for MediaStreamTrack.stop() demonstrates how to stop a multi-track stream, which is what LocalMediaStream.stop() used to be used for.


Stops the stream. When the source of the stream is a connected device (such as a camera or microphone), capture of media from the device is halted.


Not part of any specification. This interface was previously part of Media Capture and Streams but was removed in 2013.
