我决定研究 WebRTC，但不显示视频。请帮助。 我究竟做错了什么？使用 Chrome 我的代码:
<html>
<head>
<meta charset="UTF-8">
</head>
<body>
<script>
window.onload = function () {
navigator.webkitGetUserMedia({ video: true }, getStream, noStream);
};
function getStream(stream) {
var url = window.webkitURL.createObjectURL(stream);
var video = document.getElementById('video');
video.src = url;
}
function noStream(faild) {
}
</script>
<video id="video" autoplay="autoplay" width="400"></video>
</body>
</html>
最佳答案
工作代码:
<head>
<meta charset="UTF-8"></script>
</head>
<body>
<script>
window.onload = function () {
var constraints = { audio: true, video: { width: 1280, height: 720 } };
navigator.mediaDevices.getUserMedia(constraints)
.then(function(mediaStream) {
var video = document.querySelector('video');
video.srcObject = mediaStream;
video.onloadedmetadata = function(e) {
video.play();
};
})
.catch(function(err) { console.log(err.name + ": " + err.message); });
};
</script>
<video id="video" autoplay="autoplay" width="400"></video>
</body>
</html>
关于javascript - WebRTC。不显示视频，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/41127828/
