接下来为了更容易理解， 我在这分为两个页面，一个为视频者页面，另一个是观看者页面
下面代码为视频者页面：
<!DOCTYPE html><html xmlns="http://www.w3.org/1999/xhtml"><head><meta http-equiv="Content-Type" content="text/htmlcharset=utf-8" /><title></title><script src="jQuery_1.8.2.min.js"></script><script type="text/javascript">$(function () {var video = document.getElementById("video")var canvas = document.getElementById("canvas"),context = canvas.getContext("2d")var wif (navigator.webkitGetUserMedia) {navigator.webkitGetUserMedia({ video: true }, function (stream) {video.src = window.webkitURL.createObjectURL(stream)video.play()w = new WebSocket(url)w.onopen = function () {sendImg()}w.onmessage = function (e) {sendImg()}}, function () {console.log("video error")})var host = 'localhost'var port = 8888var url = 'ws://' + host + ':' + port + '/'function sendImg() {context.drawImage(video, 0, 0, 320, 320)var imgData = canvas.toDataURL()w.send(imgData)}}})</script></head><body><video id="video" width="640" height="480" style="background:#000" autoplay></video><canvas style="display:none" id="canvas" width="320" height="320"></canvas></body></html>
接下来是观看者页面：
<!DOCTYPE html><html xmlns="http://www.w3.org/1999/xhtml"><head><meta http-equiv="Content-Type" content="text/htmlcharset=utf-8" /><title></title><script src="jQuery_1.8.2.min.js"></script><script>$(function () {var host = 'localhost'var port = 8888var url = 'ws://' + host + ':' + port + '/'var w = new WebSocket(url)w.onmessage = function (e) {$("#canvas").attr("src", e.data)}})</script></head><body><img id="canvas" width="320" height="320" /></body></html>注：希望可以帮到你!
你是打算自己研发能在H5在线实时语音聊天功能的产品吗？这个大可不必，首先，技术要过硬，其次耗费时间长。如果是公司要用的话，建议直接和第三方服务商合作，比如 即构科技。他们的实时语音SDK支持双人至百万人语音通话，适合语音交友、游戏开黑、VOIP电话、网络电台和呼叫中心等场景，很好用的。欢迎分享，转载请注明来源：内存溢出
