推荐答案
查看 https://simpl.info/getusermedia/sources/ ,显示如何使用选择源
Check out https://simpl.info/getusermedia/sources/ that shows how you can select sources using
MediaStreamTrack.getSources(gotSources);
您可以再选择源,并通过它作为可选到getUserMedia
You can then select the source and pass it in as optional into getUserMedia
var constraints = {
audio: {
optional: [{sourceId: audioSource}]
},
video: {
optional: [{sourceId: videoSource}]
}
};
navigator.getUserMedia(constraints, successCallback, errorCallback);
这是目前情况稳定Chrome浏览器和移动完全可用(如V30的)
It is now fully available in Stable Chrome and mobile (As of v30)
