我正在使用WebRTC开发视频通话功能,并面临一个非常奇怪的问题。
当我拨打电话时,一切都很好,我正在收到远程视频流,但是当我接到电话时,我会看到一个没有远程视频的黑屏。奇怪的是,当我刷新页面时,我得到远程视频!
在控制台中,我得到以下内容:
视频约束错误
但是当我刷新页面时,我得到了视频对象。
这是 index.html ,
中的视频容器<video id="video-container" autoplay="autoplay" class="video-style"></video>
Main.js:
(function() {
var vertoHandle, vertoCallbacks, currentCall;
document.getElementById("make-call").addEventListener("click", makeCall);
document.getElementById("hang-up-call").addEventListener("click", hangupCall);
document.getElementById("answer-call").addEventListener("click", answerCall);
$.verto.init({}, bootstrap);
function bootstrap(status) {
vertoHandle = new jQuery.verto({
// ID of HTML video tag where the video feed is placed.
tag: "video-container",
deviceParams: {
// Asking for camera permissions and devices.
useCamera: 'any',
useMic: 'any',
useSpeak: 'any',
},
login: '1008@127.0.0.1',
passwd: '1234',
socketUrl: 'wss://127.0.0.1:8082',
ringFile: '',
iceServers: true,
}, vertoCallbacks);
};
vertoCallbacks = {
onWSLogin : onWSLogin,
onWSClose : onWSClose,
onDialogState: onDialogState,
}
function onWSLogin(verto, success) {
console.log('onWSLogin', success);
}
function onWSClose(verto, success) {
console.log('onWSClose', success);
}
function onDialogState(d) {
console.debug('onDialogState', d);
if(!currentCall) {
currentCall = d;
}
switch (d.state.name) {
case 'trying':
//
break;
case 'ringing':
alert('Someone is calling you, answer!');
break;
case 'answering':
//
break;
case 'active':
//
break;
case 'hangup':
//
break;
case 'destroy':
//
break;
}
}
function makeCall() {
vertoHandle.videoParams({
minWidth: 320,
minHeight: 240,
maxWidth: 640,
maxHeight: 480,
// The minimum frame rate of the client camera, Verto will fail if it's
// less than this.
minFrameRate: 15,
// The maximum frame rate to send from the camera.
vertoBestFrameRate: 30,
});
currentCall = vertoHandle.newCall({
useVideo: true,
mirrorInput: true,
destination_number : '3520',
caller_id_name : 'Test Caller',
caller_id_number: '1008',
outGoingBandwidth: 'default',
inComingBandwidth: 'default',
useStereo: true,
useMic: true,
useSpeak: true,
userVariables: {
email: 'test@test.com'
},
dedEnc: false,
});
}
function hangupCall() {
currentCall.hangup();
};
function answerCall() {
currentCall.answer();
}
})();
这段代码出了什么问题?
提前致谢!
答案 0 :(得分:2)
经过一些研究,我找到了解决方案。
我收到错误Video constraints false
,因为它们是在拨打电话时设置的,而不是在接收时设置的。所以我手动设置属性,
useVideo: true
deviceParams 。
现在,我在拨打电话时也收到了视频。
