Kurento-utils WebRtcPeerSendrecv 是否关注所有选项？

Question

我正在使用 WebRtcPeerSendrecv 对象与 kurento 服务器建立与 WebRTC 端点的通信。我想要 select 此处制作的视频输入：https://webrtc.github.io/samples/src/content/devices/input-output/

我遇到的问题是添加属性 video/deviceId 不起作用。

options = {
    audio : false,
    localVideo : videoInput,
    remoteVideo : videoOutput,
    video: {
        deviceId: {exact: devcs[0]}
        },
    onicecandidate : onIceCandidate,
    onerror : onError
}

唯一以其他方式制作的东西是我正在与 Kurento-utils 的 WebRtcPeerSendrecv 建立我的 WebRtc 连接，最初它是使用 navigator.getUserMedia(...) 制作的。据我所知，WebRtcPeerSendrecv 正在调用 getUserMedia，但我不确定是否所有属性都被一对一复制。我在这里查看了 https://github.com/Kurento/kurento-utils-js/blob/master/lib/WebRtcPeer.js 的源代码，但我不确定。有人遇到过类似的问题吗？

编辑：

有更广泛的源代码，其中包含 webRTCPeer 创建（测试其他选项）：

var options;
    console.log(devcs);
    if(devcs.length == 2){
        console.log("CAMERA ID SET");
        options = {
            audio : false,
            localVideo : videoInput,
            remoteVideo : videoOutput,
            video: {
                optional: [{sourceId: devcs[0]}]
                //deviceId: {exact: devcs[0]}
            },
            onicecandidate : onIceCandidate,
            onerror : onError
        }
    }
    else{
        console.log("THERE ARE NO 2 CAMERAS");
        options = {
                audio : false,
                localVideo : videoInput,
                remoteVideo : videoOutput,
                onicecandidate : onIceCandidate,
                onerror : onError
            }
    }
    webRtcPeer = new kurentoUtils.WebRtcPeer.WebRtcPeerSendrecv(options,
            function(error) {
                if (error) {
                    return console.error(error);
                }
                webRtcPeer.generateOffer(onOfferIncomingCall);
            });

我已经尝试过使用两个 ID 的两个选项，我在 devcs 数组中获取它们，但都不起作用 - 我总是有一个前置摄像头。正如我检查的那样，devcs 包含 ID。我有办法获得它们。

有一些日志，但不是太多（日志来自 android- 我正在 WebView (chromium) 中构建它）：

Answer 1

解决方法是连接不上kurento客户端。必须通过 mediaConstraint 选项添加视频属性：

var constraints = {
                audio:true,
                video:{
                    deviceId: {exact: devcs[1]}
                }
        };
        options = {
            audio : false,
            localVideo : videoInput,
            remoteVideo : videoOutput,
            mediaConstraints:constraints,
            onicecandidate : onIceCandidate,
            onerror : onError
        }

我现在面临的另一个问题是相机仅使用一个视频 ID 即可正常工作：使用 devcs[0]。第二个摄像头 (devcs[1]) 有黑色视频元素和日志中的错误：

12-21 13:09:12.562 9704-9757/eu.kros.t_medapp W/CameraBase: An error occurred while connecting to camera: 0

12-21 13:09:12.5629704-9757/eu.kros.t_medapp E/cr_VideoCapture: allocate: Camera.open: java.lang.RuntimeException: Fail to connect to camera service

12-21 13:09:12.568 9704-9757/eu.kros.t_medapp E/cr_VideoCapture: stopCapture: mCamera is null

当我解决它时我会更新这个post。
