HTML5: Recording Audio,Video Streams

MediaStreamRecorder API is webRTC API that supports recording streams with getUserMedia or remote streams passed over peerconnection session.



 
    <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("uploadvideo.php", data, onUploadSuccess);
    }
    function onUploadSuccess() {
        alert ('video uploaded');
    }
 
    </script>
 



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


"getRecorderdedData" return  blob that was recorded.

uploadvideo.php is to store recorded blob in file. MediaStreamRecorder API is still under implementation, use chrome canary, it helps you to build advanced apps.

what code should contain uploadvideo.php, to save blub in a file? or it is not already running in normal chrome? because when i press the record button nothing happens. It is only for canary?

I'm trying to make the video comments service. Аre there other ways of recording video with sound, without the use of flash (for cross platform)?
Thank you.
