Web IM SDK 支持实时通话功能。用户可以与好友进行实时视频聊天。
注意：视频通话功能只支持https+Webkit浏览器。
集成步骤如下：
1. 在html中引入以下文件。其中，前三个为集成Web IM SDK必须引用的文件，后两个为集成即时视频功能需要引用的文件。
<script src="../demo/javascript/dist/webim.config.js"></script>
<script src="./dist/strophe-1.2.8.min.js"></script>
<script src="./dist/websdk-1.4.6.js"></script>
<script src="../webrtc/dist/adapter.js"></script>
<script src="../webrtc/dist/webrtc-1.4.6.js"></script>
2. 初始化WebRTC Call。
var rtcCall = new WebIM.WebRTC.Call({
connection: conn,
mediaStreamConstaints: {
audio: true,
video: true
},
listener: {
onAcceptCall: function (from, options) {
console.log('onAcceptCall::', 'from: ', from, 'options: ', options);
},
//通过streamType区分视频流和音频流，streamType: 'VOICE'(音频流)，'VIDEO'(视频流)
onGotRemoteStream: function (stream, streamType) {
console.log('onGotRemoteStream::', 'stream: ', stream, 'streamType: ', streamType);
var video = document.getElementById('video');
video.srcObject = stream;
},
onGotLocalStream: function (stream, streamType) {
console.log('onGotLocalStream::', 'stream:', stream, 'streamType: ', streamType);
var video = document.getElementById('localVideo');
video.srcObject = stream;
},
onRinging: function (caller) {
console.log('onRinging::', 'caller:', caller);
},
onTermCall: function (reason) {
console.log('onTermCall::');
console.log('reason:', reason);
},
onIceConnectionStateChange: function (iceState) {
console.log('onIceConnectionStateChange::', 'iceState:', iceState);
},
onError: function (e) {
console.log(e);
}
}
});
3. 调用RTC接口。
// 视频呼叫对方
var call = function () {
rtcCall.caller = 'mengyuanyuan';
rtcCall.makeVideoCall('asdfghj');
};
// 音频呼叫对方
var call = function () {
rtcCall.caller = 'mengyuanyuan';
rtcCall.makeVoiceCall('asdfghj');
};
// 关掉/拒绝视频
var endCall = function () {
rtcCall.endCall();
}
// 接受对方呼叫
var acceptCall = function () {
rtcCall.acceptCall();
}
4. 绑定事件。
document.getElementById('rtCall').onclick = call;
document.getElementById('rtEndCall').onclick = endCall;
document.getElementById('rtAcceptCall').onclick = acceptCall;
