This issue was originally filed by jvande...@gmail.com

What steps will reproduce the problem?

In Chromium Version 29.0.1530.0 (204370) running the code bellow on a web came with a 640x426 resolution produces a video element with dimensions 1280 x 720. The video is stretched to fit within it.

window.navigator.getUserMedia(video:{'mandatory':
                        { 'minWidth': 1000 }}
  ).then((stream) {
    video.autoplay = true;
    video.src = Url.createObjectUrl(stream);
  });

What is the expected output? What do you see instead?

On my laptop I expected an exception to be raised indicating that computer has no device matching the constraints. On my phone running chrome beta I expect the environment facing camera to be selected as it does meet the constraint.

What version of the product are you using? On what operating system?

Dart SDK version 0.6.3.3_r24898
Chromium Version 29.0.1530.0 (204370)
Chrome Version 27.0.1453.116

This is a widely enough used API that we should see if this bug can be fixed without an API change.

This seems to be doing what I'd expect in Dartium and Chrome now. In Firefox it does show a stream even though it doesn't meet the constraints, but I suspect that's a Firefox issue. The API isn't supported on Safari.

Added AssumedStale label.
