Is there a layouttest or some other JS-driven test that can be enabled now?

[wjia(left Chromium), 2013/01/30 18:25:47]

There is a layout test for media
stream(platform/chromium/media/video-capture-preview.html). It's using a faked
video capture module. More tests (at browser level) would be added later.

Do you want to enumerate here the reasons why each is disabled (as is done
above) or link to a crbug where the reasons are listed?

[wjia(left Chromium), 2013/01/30 18:25:47]

Added comments on the reason why these tests can't pass. They share the same
root cause.
