在webrtc中使用MediaDevices.getUserMedia()切换摄像机 [英] switch camera using MediaDevices.getUserMedia() in webrtc

问题描述

我正在尝试navigator.MediaDevices.getUserMedia()webrtc在通话期间切换设备摄像头.此功能在桌面浏览器上运行良好，但在mozilla android上则无法运行. 这是我正在使用的代码.

I am trying navigator.MediaDevices.getUserMedia() webrtc to switch the device camera during the call. This functionality is working fine on the desktop browser but on mozilla android it is not working. Here is my code that i am using .

var front=false;

var myConstraints = {  video: { facingMode: (front? "user" : "environment")} }; 
navigator.mediaDevices.getUserMedia(myConstraints).then(function(stream) {

}

对此有任何想法吗?

推荐答案

电话硬件通常不允许同时打开前后摄像头.在获取其他摄像机之前，将代码更改为stop()现有流.

Phone hardware typically doesn't allow opening both the front and back camera at the same time. Change your code to stop() the existing stream before getting the other camera.
