           Summary: getUserMedia() Test Error in Chrome
           Product: WebRTC Working Group
           Version: unspecified
          Platform: PC
        OS/Version: Windows NT
            Status: NEW
          Severity: normal
          Priority: P2
         Component: WebRTC API
        AssignedTo: public-webrtc@w3.org
        ReportedBy: gaowenmei@huawei.com

Browser: Chrome 21.0.1155.2

I wrote a simple demo to test getUserMedia() function. The demo is just to show
the video stream from my local camera.

But I encountered a strange problem: 

1) If I open the test.html directly in the browser(double click or drag to the
browser), there will be a popup window to obtain user's confirmation. I clicked
the "Allowed" button, but I could see nothing on the page. At the same time,
however, there was a success notification on the taskbar, saying "file:// is
using your camera and microphone". 

2) If I put the test.html to apache's home directory and open the page through
"http://localhost/test.html", there will also be a popup window. When I clicked
the "Allowed" button, I could see the video stream from my camera successfully!
At the same time, there was also a success notification on the taskbar, saying
"http://localhost is using your camera and microphone".

I was wondering what is the reason of the problem. Is there any difference
between "double-click open" and "localhost open" when calling getUserMedia()
function?

Thanks.
