Fix the webcam freezing issue on the Windows 10 Anniversary Update

0 235

Microsoft recently released the Anniversary Update bringing a lot of new features and improvements to Windows 10. Alongside, it also has some things broken. One of the new issues that popped up recently is, the Webcam freezing issue. This bug won’t let you make Skype calls if you’re on the Anniversary Update. Users say their cameras are either not working at all or freezing constantly after the update along with webcam based applications like Skype and more.

According to one member of the Microsoft’s Windows Camera team, the problem is caused by the Anniversary Update removing support for two video compression formats, including MJPEG and H.264 codecs on Windows 10, and opting to support YUY2 encoding instead. The company claims that the decision was made to prevent performance issues due to the change on how Windows Store apps can now access the camera features with the Anniversary Update.

Cause Of Webcam Freezing not working

In the Anniversary Update, Microsoft allows multiple apps to access a single webcam at the same time. The problem with MJPEG is that multiple apps could then decode the stream at the same time, which would reduce system performance unnecessarily. It appears Microsoft’s simple solution of disallowing compression formats led to a much bigger problem. Potentially millions of webcams were suddenly broken, since they would freeze after failing to enable the blacklisted formats. Microsoft has acknowledged the problem, but says they will not be issuing a permanent fix until September.
