title: Can't record higher framerate in recordRTC
body: <p>Can't record higher than 30 fps using recordRTC to webm. Camera is capable of recording at 60 fps at the desired resolution at 1920x1080. Any ideas on how to fully record the 60 fps?</p>
  
  <pre><code>    var options = {
        mimeType: 'video/webm',
        video: {
            width: 1920,
            height: 1080
         },
        bitsPerSecond: 51200000,
        frameRate: 60
      };
    this.stream = stream;
    this.recordRTC = RecordRTC(stream, options);
  </code></pre>
