This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for usage in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the specification changes.

The srcObject property of the HTMLMediaElement interface sets or returns the object which serves as the source of the media associated with the HTMLMediaElement. This is usually a MediaStream but can, according to the specification, be a MediaSource, Blob, or File.


var mediaStream = HTMLMediaElement.srcObject
HTMLMediaElement.srcObject = mediaStream


MediaStreamMediaSourceBlob, or File object (though see the compatibility table for what is actually supported).
