    <p>Ok, I'm going to try and make my question as clear as possible, but I'm pretty confused, so let me know if I'm not getting the message across. </p> <p>I'm trying to use getUserMedia to use the webcam, and then use this</p> <p><a href="http://www.w3.org/TR/mediastream-recording/" rel="nofollow noreferrer">http://www.w3.org/TR/mediastream-recording/</a></p> <p>to record a brief captured video. Problem is, when I try to define new MediaRecorder(stream), I'm told that it is undefined. I haven't used this api before, so I don't really know what I'm missing. Here is the relevant code:</p> <pre><code>function onVideoFail(e) { console.log('webcam fail!', e); }; function hasGetUserMedia() { return !!(navigator.getUserMedia || navigator.webkitGetUserMedia || navigator.mozGetUserMedia || navigator.msGetUserMedia); } if (hasGetUserMedia()) { window.URL = window.URL || window.webkitURL; navigator.getUserMedia = navigator.getUserMedia || navigator.webkitGetUserMedia || navigator.mozGetUserMedia || navigator.msGetUserMedia; if (navigator.getUserMedia) { navigator.getUserMedia({video: true, audio: false}, function(stream){ var video = document.querySelector('video'); var recorder = new MediaRecorder(stream); &lt;&lt;&lt;&lt;&lt;&lt; THIS IS MY PROBLEM SPOT video.src = window.URL.createObjectURL(stream); video.play(); // webcamstream = stream; // streamrecorder = webcamstream.record(); }, onVideoFail); } else { alert('failed'); } } else { alert('getUserMedia() is not supported by this browser!!'); } </code></pre> <p>I've been trying to look at this for reference:</p> <p><a href="https://stackoverflow.com/questions/16319470/html5-getusermedia-record-webcam-both-audio-and-video">HTML5 getUserMedia record webcam, both audio and video</a></p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
