The latest HTML5 spec includes a <device> element, this should be implemented by WebKit.
URL of the W3C Media Capture spec is http://dev.w3.org/2009/dap/camera/
Mozilla's bug is at https://bugzilla.mozilla.org/show_bug.cgi?id=451674
A first proposal on the device element has been submitted for code review: https://bugs.webkit.org/show_bug.cgi?id=47264
However during the review some questions and concerns have been raised about its design. As a consequence, a discussion thread with an alternative proposal has been started to analyze the problem: https://lists.webkit.org/pipermail/webkit-dev/2011-January/015822.html
Meanwhile, a first patch has been proposed to introduce the appropriate compilation guards: https://bugs.webkit.org/show_bug.cgi?id=53595
This first patch should allow future patches without forcing any specific design approach.
Setting as wontfix as the spec has been dropped in favor of the MediaStream API.
