有没有办法在Chrome中设置默认的捕获设备，例如navigator.setUserMedia（）？ （谷歌浏览器）
[英]Is there a way to set default capture device in Chrome like navigator.setUserMedia()? (GOOGLE CHROME)
问题描述
I am currently trying to switch the input video source being displayed but from what I have found, navigator.getUserMedia() can be used to get the localMediaStream but it only has a handle on one of each audio and video sources available to the browser. 
我目前正在尝试切换显示的输入视频源，但是从我发现的结果来看，可以使用navigator.getUserMedia（）来获取localMediaStream，但它仅对浏览器可用的每个音频和视频源之一都有一个句柄。
Is there a way (using html or javascript) to set the default camera in Chrome if I have the device IDs? 如果我具有设备ID，是否可以使用Chrome或javascript设置默认摄像头的方法？

Check this demo: https://webrtc.github.io/samples/src/content/getusermedia/source/ 检查此演示： https : //webrtc.github.io/samples/src/content/getusermedia/source/
Basically, you use MediaStreamTrack.getSources, pass the sourceId optional constraint to getUserMedia and you're good. 基本上，您使用MediaStreamTrack.getSources，将sourceId可选约束传递给getUserMedia，您就很好。 You can store the device ids, they stay the same until the cookies are cleared. 您可以存储设备ID，直到清除cookie为止，它们保持不变。
