addtrack

这篇翻译不完整。请帮忙从英语翻译这篇文章

An addtrack  is fired when the browser adds a track to a MediaStream (such as when a RTCPeerConnection is renegotiated or a stream being captured using HTMLMediaElement.captureStream() gets a new set of tracks because the media element being captured loaded a new source.

The addtrack event does not get fired when JavaScript code explicitly adds tracks to the stream (by calling addTrack()).

An event handler for this event can be added by setting the MediaStream.onaddtrack property, or by calling addEventListener() on the MediaStream which you want to monitor for track additions.
