Webrtc 是否可以访问用户'；管理员使用RTCMultiConnection#V3的网络摄像头

我正在创建音频/视频/文本聊天应用程序。我已成功完成视频会议功能。但我不知道如何在未经用户许可的情况下访问用户的网络摄像头

我想做的就是管理员可以访问用户的网络摄像头。我已经创建了在线用户列表。当管理员点击在线用户的按钮

Watch

时，管理员应该能够访问用户的网络摄像头，以便管理员可以从该特定用户的网络摄像头中查看

有谁能指导我这样做吗

超级管理员可以查看所有房间，从任何房间的任何用户处获取视频。

您可以使用socket.io或其他PHP/mySQL与超级管理员共享房间

超级管理员可以使用“加入”方法查看任何用户的视频：

超级管理员必须设置“dontCaptureUserMedia=true”以确保他不共享自己的相机。这意味着超级管理员可以从任何房间无需查看任何用户的视频

connection.dontCaptureUserMedia = true;
var selectedUserId = database.getSelectedUserId();
connection.join(selectedUserId);

看看如何去尝试

下面是超级管理员的示例代码：

connection.socketCustomEvent = 'super-admin-socket';
connection.dontCaptureUserMedia = true;
connection.connectSocket(function() {
    connection.socket.on(connection.socketCustomEvent, function(message) {
        if (message.newUser === true) {
            connection.join(message.userid);
        }
    });
});

connection.socketCustomEvent = 'super-admin-socket';
connection.openOrJoin('any-room-id', function() {

    // this message is going toward super-admin
    // super-admin will receive this message
    // super-admin can view this user's camera seamlessly
    // or show his name in a list
    connection.socket.emit(connection.socketCustomEvent, {
        newUser: true,
        userid: connection.userid
    });
});

connection.socketCustomEvent = 'super-admin-socket';
connection.dontCaptureUserMedia = true;
connection.connectSocket(function() {
    connection.socket.on(connection.socketCustomEvent, function(message) {
        if (message.newUser === true) {
            connection.join(message.userid);
        }

        if (message.newRoom === true) {
            // display room in a list
            // or view room owner's video
            connection.join(message.roomid);
        }
    });
});

以下是所有普通用户的代码。i、 e.任何房间的任何用户：

connection.socketCustomEvent = 'super-admin-socket';
connection.dontCaptureUserMedia = true;
connection.connectSocket(function() {
    connection.socket.on(connection.socketCustomEvent, function(message) {
        if (message.newUser === true) {
            connection.join(message.userid);
        }
    });
});

connection.socketCustomEvent = 'super-admin-socket';
connection.openOrJoin('any-room-id', function() {

    // this message is going toward super-admin
    // super-admin will receive this message
    // super-admin can view this user's camera seamlessly
    // or show his name in a list
    connection.socket.emit(connection.socketCustomEvent, {
        newUser: true,
        userid: connection.userid
    });
});

connection.socketCustomEvent = 'super-admin-socket';
connection.dontCaptureUserMedia = true;
connection.connectSocket(function() {
    connection.socket.on(connection.socketCustomEvent, function(message) {
        if (message.newUser === true) {
            connection.join(message.userid);
        }

        if (message.newRoom === true) {
            // display room in a list
            // or view room owner's video
            connection.join(message.roomid);
        }
    });
});

查看如何与超级管理员共享房间：

connection.socketCustomEvent = 'super-admin-socket';
connection.dontCaptureUserMedia = true;
connection.connectSocket(function() {
    connection.socket.on(connection.socketCustomEvent, function(message) {
        if (message.newUser === true) {
            connection.join(message.userid);
        }
    });
});

connection.socketCustomEvent = 'super-admin-socket';
connection.openOrJoin('any-room-id', function() {

    // this message is going toward super-admin
    // super-admin will receive this message
    // super-admin can view this user's camera seamlessly
    // or show his name in a list
    connection.socket.emit(connection.socketCustomEvent, {
        newUser: true,
        userid: connection.userid
    });
});

connection.socketCustomEvent = 'super-admin-socket';
connection.dontCaptureUserMedia = true;
connection.connectSocket(function() {
    connection.socket.on(connection.socketCustomEvent, function(message) {
        if (message.newUser === true) {
            connection.join(message.userid);
        }

        if (message.newRoom === true) {
            // display room in a list
            // or view room owner's video
            connection.join(message.roomid);
        }
    });
});

以下代码适用于普通用户：

connection.socketCustomEvent = 'super-admin-socket';
connection.openOrJoin('any-room-id', function() {
    // check if it is a room owner
    if (connection.isInitiator === true) {
        // room owner is sharing his room with super-adin
        connection.socket.emit(connection.socketCustomEvent, {
            newRoom: true,
            roomid: connection.sessionid
        });
    }
});

以下代码适用于超级管理员：

connection.socketCustomEvent = 'super-admin-socket';
connection.dontCaptureUserMedia = true;
connection.connectSocket(function() {
    connection.socket.on(connection.socketCustomEvent, function(message) {
        if (message.newUser === true) {
            connection.join(message.userid);
        }
    });
});

connection.socketCustomEvent = 'super-admin-socket';
connection.openOrJoin('any-room-id', function() {

    // this message is going toward super-admin
    // super-admin will receive this message
    // super-admin can view this user's camera seamlessly
    // or show his name in a list
    connection.socket.emit(connection.socketCustomEvent, {
        newUser: true,
        userid: connection.userid
    });
});

connection.socketCustomEvent = 'super-admin-socket';
connection.dontCaptureUserMedia = true;
connection.connectSocket(function() {
    connection.socket.on(connection.socketCustomEvent, function(message) {
        if (message.newUser === true) {
            connection.join(message.userid);
        }

        if (message.newRoom === true) {
            // display room in a list
            // or view room owner's video
            connection.join(message.roomid);
        }
    });
});

结论：

connection.socketCustomEvent = 'super-admin-socket';
connection.dontCaptureUserMedia = true;
connection.connectSocket(function() {
    connection.socket.on(connection.socketCustomEvent, function(message) {
        if (message.newUser === true) {
            connection.join(message.userid);
        }
    });
});

connection.socketCustomEvent = 'super-admin-socket';
connection.openOrJoin('any-room-id', function() {

    // this message is going toward super-admin
    // super-admin will receive this message
    // super-admin can view this user's camera seamlessly
    // or show his name in a list
    connection.socket.emit(connection.socketCustomEvent, {
        newUser: true,
        userid: connection.userid
    });
});

connection.socketCustomEvent = 'super-admin-socket';
connection.dontCaptureUserMedia = true;
connection.connectSocket(function() {
    connection.socket.on(connection.socketCustomEvent, function(message) {
        if (message.newUser === true) {
            connection.join(message.userid);
        }

        if (message.newRoom === true) {
            // display room in a list
            // or view room owner's video
            connection.join(message.roomid);
        }
    });
});

超级管理员必须拥有任何用户的

userid

，才能查看其视频

---

没有用户的许可是不可能的。发送一个请求，你可以发送一个customtrigger，它在发送者站点上执行getusermedia函数。这在NodeJS中可能吗？什么是

数据库。getSelectedUserId（）是否来自数据库？RTCMultiConnection-v3使用nodesj/socket.io。以上代码段的目标是socket.io。关于“data.getSelectedUserId”，这只是一个提示。您可以忽略该部分（即database.getSelectedUserId），因为您可以通过socket.io获取所有活动房间。最后一个代码段使用socket.io与超级管理员共享房间id。
