我们将能够创建流轨道的对象，但媒体流始终由浏览器提供.要么是本地媒体流，您可以从 getUserMedia() 方法获取，要么是远程媒体流，您从对等连接接收.

We will be able to create the object of the streams tracks, but the Media Stream is always provided by the browser. Either it is a local Media Stream and you get it from the getUserMedia() method, or it's a remote Media Stream and you receive it from the peer connection.

MediaStreamTrack 是由浏览器 API 创建的对象，其中的媒体(本地或远程)始终由浏览器提供，使用麦克风/摄像头或 PeerConnection 中的媒体.

The MediaStreamTrack is an object created by the browser API and the media in it (local or remote) is always provided by the browser, using microphones/cameras or media from the PeerConnection.
