在视频元素上切换视频轨道
我想知道是否可以在给定＆LT上的视频轨道之间切换；视频＆gt;元素
<video id='vid'></video>
我能够使用以下内容在流中添加多个视频轨道：
vid.captureStream().addTrack(added track)
从本质上讲，我能够添加多个视频轨道。但是，就 该元素包含多个视频曲目，不会播放视频。 如果我删除额外的曲目，则视频将播放附加的曲目。
我试图欺骗track.Enabled属性，但似乎什么也没做。
这个想法是我想最初加载一堆轨道并在它们之间切换。可能的？
至关重要的是，不添加和删除视频轨道，而只是最初加载它们。
I'm wondering if it's possible to switch between video tracks on a given < video > element
<video id='vid'></video>
I was able to add multiple video tracks to the stream using:
vid.captureStream().addTrack(added track)
Essentially I was able to add multiple video tracks. But as soon as
the element contains more than one video track, no video will play.
If I remove the extra tracks, the video will play the added tracks.
I tried fooling around with the track.enabled property but it doesn't seem to do anything.
The idea is I want to load a bunch of tracks initially and switch between them. Possible?
It is essential that no video tracks are added and removed, only initially loading them.
