getusermedia DevicesNotFoundError在最新的浏览器中抛出 [英] getusermedia DevicesNotFoundError thrown in latest browsers
问题描述
我现在一直在使用getUserMedia()作为WebRtc,但自从浏览器的最新更新以来,我一直无法使用它。在以前的版本中工作正常。
I have been using getUserMedia() for WebRtc for a while now but since the latest update of browsers I have not been able to use this. On previous versions worked fine.

推荐答案
我找到了解决方案。在新版本中,当我们指定约束 {audio:true,video:true}
时,我们将其中的任何一个指定为true,以至于需要存在相应的硬件。否则它会抛出 DevicesNotFoundError
。
I found the solution. In newer versions when we specify the constraints { audio: true, video: true }
either of which ever we specify as true that corresponding hardware need to be present. otherwise it will throw DevicesNotFoundError
.
这是我使用的代码。
navigator.mediaDevices.getUserMedia({ audio: true, video: false})
.then(function(stream) {
/* use the stream */
})
.catch(function(err) {
/* handle the error */
});
