Tizen Developers

I want to use getusermedia to make an application with camera/microphone, but I can not get any data from the MediaStream use Tizen Device.

And the sample demo provided by the SDK named 'selfCamera' does not work either.

here is the part of my code:

      ​window.URL = window.URL || window.webkitURL;
      navigator.getUserMedia  = navigator.getUserMedia || navigator.webkitGetUserMedia;
      var recorder;
      var audio = document.querySelector('audio');
      var systemIO = new SystemIO();

      function startRecording() {
        if (navigator.getUserMedia) {
          navigator.getUserMedia({audio: true}, onSuccess, onFail);
        } else {
          console.log('navigator.getUserMedia not present');
        }
      }

      function stopRecording() {

        recorder.stop();
        recorder.exportWAV(function(s) {
          //audio.src = window.URL.createObjectURL(s);
          //it does not work here , which works in chrome.
          var reader = new FileReader();
          reader.onload = function (e) {
            audio.src = e.target.result;
            //I can not get any audio data, which works in chrome too.
            console.log(e.target.result);
          };
          reader.readAsDataURL(s);
        });
      }
      $('#stop').on('click',function(e) {
        stopRecording();
      });
      $('#start').on('click',function(e) {
        startRecording();
      });
