Is audio not possible to have set to true? If that's the case a bug should be
filed. 

Please leave it as:
audio: $('audio').checked,
since having the actual constraint being something different from the checkbox
state will surely confuse users.

Done.

Is there no way to get both screen capture and a webcam video stream at the same
time? It might be worth investigating and possibly file a bug if so.

[jansson, 2013/04/05 10:29:42]

It's not possible to send both with our test pages. I do not know if it's
possible by just adding it a as a separate track?

[kjellander_chromium, 2013/04/08 14:19:51]

I think it should be possible according to the spec, but this test page doesn't
support it properly (yet). 
Please investigate if a bug should be filed if Chrome doesn't handle that
combination of constraints properly.

Depending on if it's a bug or not to not being able to have audio: true I think
you can simplify the if-else construct here to make it smaller.

Example (not tested):
var constraints = {
  audio: $('audio').checked,
  video: $('video').checked,
};
if $('screencapture').checked
  constraints['video'] = {mandatory: {chromeMediaSource: 'screen'}};

[jansson, 2013/04/05 10:29:42]

Done.

+    };
   $('getusermedia-constraints').value =
       JSON.stringify(constraints, null, ' ');
