使用getusermedia（）的html5中的音频和视频录像机

Question

我正在创建一个应用程序来记录音频和视频，但它只适用于Google铬或金丝雀。我想在Internet Explorer和Mozilla Firefox下工作。这是我的代码。 我们可以做到这一点，而不使用用户媒体吗？如果是的话请告诉我。

请参阅此链接 http://davidwalsh.name/demo/camera.php

MediaStreamRecorder是用于记录一个getUserMedia API的WebRTC（）流。它允许网络应用程序通过实时音频/视频会话创建文件。

MediaStreamRecorder目前未实现。你应该等待在所有浏览器中实现它。

<video autoplay></video> 

    <script language="javascript" type="text/javascript"> 
    function onVideoFail(e) { 
     console.log('webcam fail!', e); 
     }; 

    function hasGetUserMedia() { 
     // Note: Opera is unprefixed. 
     return !!(navigator.getUserMedia || navigator.webkitGetUserMedia || 
       navigator.mozGetUserMedia || navigator.msGetUserMedia); 
    } 

    if (hasGetUserMedia()) { 
     // Good to go! 
    } else { 
     alert('getUserMedia() is not supported in your browser'); 
    } 

    window.URL = window.URL || window.webkitURL; 
    navigator.getUserMedia = navigator.getUserMedia || 
          navigator.webkitGetUserMedia || 
           navigator.mozGetUserMedia || 
           navigator.msGetUserMedia; 

    var video = document.querySelector('video'); 
    var streamRecorder; 
    var webcamstream; 

    if (navigator.getUserMedia) { 
     navigator.getUserMedia({audio: true, video: true}, function(stream) { 
     video.src = window.URL.createObjectURL(stream); 
     webcamstream = stream; 
    // streamrecorder = webcamstream.record(); 
     }, onVideoFail); 
    } else { 
     alert ('failed'); 
    } 

    function startRecording() { 
     streamRecorder = webcamstream.record(); 
     setTimeout(stopRecording, 10000); 
    } 
    function stopRecording() { 
     streamRecorder.getRecordedData(postVideoToServer); 
    } 
    function postVideoToServer(videoblob) { 

     var data = {}; 
     data.video = videoblob; 
     data.metadata = 'test metadata'; 
     data.action = "upload_video"; 
     jQuery.post("http://www.kongaraju.in/uploadvideo.php", data, onUploadSuccess); 
    } 
    function onUploadSuccess() { 
     alert ('video uploaded'); 
    } 

    </script> 

    <div id="webcamcontrols"> 
     <button class="recordbutton" onclick="startRecording();">RECORD</button> 
    </div>
