Microsoft can’t seem to catch a lucky break. After launching a fairly successful new Operating System in the form of Windows 10, they’ve now broken millions of webcams of users who upgraded to the Anniversary Update. So if you felt that your webcam stopped working after upgrading, you aren’t alone. An update is already in the works to fix this, but wait till September to get it. How did all this happen, you ask?
It turns out, Microsoft had made the Windows 10 Anniversary Update to not allow USB webcams to play MJPEG or H264 encoded streams. The only allowed encoding, it appears, is YUY2. Why would Microsoft do that? Because there are now newer ways to for Windows applications to access webcams and use the MJPEG or H264 encoded streams, which would lead to duplicate encoding. Disabling this has led webcams to freeze when it tries to stream anything with that particular codec.
YUY2 is an uncompressed YUV image format used for raw video storage. It’s native to Windows, but simple enough that tools on other platforms can handle it if encountered in an AVI file. – Reddit user, ack_complete
The Anniversary Update has been available since the beginning of August and some issues were reported even back then. But only in the past few days was the true effect of the ordeal unearthed, by a post on Thurrot.com. Of course, the team behind this has responded and their reasoning to restrict the popular codecs, seems logical.
There is no guarantee that a media type such as MJPEG will be supported on all cameras (for example, the Surface Pro 4 / Surface Book cameras do not support it). – Mike M, Windows Camera Team.
Without getting into the real technical stuff, it’s important to note that you can’t do much by yourself to fix the situation. The best option, if you’re webcam is already gone, is to stay put and wait for the fix to be rolled out by the Microsoft team. And if you haven’t yet upgraded to the Anniversary Update, then you should wait till this fix is rolled out.
There is a workaround that has been doing the rounds, initially tweeted by Rafael Rivera. But, only try this if you really know your way around Windows registry. Also know that this is not an official solution, so choose to go ahead at your own risk. Neither we nor the folks mentioned should be held accountable for any further damage.
If you still wanna go ahead, open the Run window by hitting the Windows key + R simultaneously and then type regedit inside the box. When you hit enter, browse to
HKLM\SOFTWARE\WOW6432Node\Microsoft\Windows Media Foundation\Platform, add DWORD “EnableFrameServerMode” and set to 0
You will need to restart the Skype application if it was running and then try again to see if this method works.
