The image is also upside-down on Windows 7 64-bit with a no-name webcam detected as "HP Basic Starter Camera", which works fine in Opera 12 and other programs.

From IRC:

<jesup> anant: the upside-down thing I think was fixed in webrtc.org; not sure if before or after our last pull (I thought before).  Only happens with some cameras under Windows I think
<jesup> fabrice was hitting it on a Logitech (910?)
<anant> yes, it happened on windows for me with a microsoft quickcam

Still on Windows 7 64-bit, but this time on a Dell laptop, the image is fine with the built-in webcam Microsoft Laptop Integrated Webcam 0.3M.

Haven't seen this in the past few months. Closing as wfm. If it ends up reproducing again on the latest builds, feel free to reopen.
