On August 2nd, Microsoft released the Anniversary Update for Windows 10 and when the bits arrived on computers around the globe, it brought with it new features and also broke webcams for millions of consumers. If your webcam has stopped functioning since the release of the Anniversary update, you are not alone but the good news is a fix is coming, hopefully in September.
Microsoft made a significant change with the release of Windows 10 and support for webcams that is causing serious problems for not only consumers but also the enterprise. The problem is that after installing the update, Windows no longer allows USB webcams to use MJPEG or H264 encoded streams and is only allowing YUY2 encoding.
Why did the company remove these options? The short answer is that with the Anniversary update there are new scenarios for applications to be able to access the webcam and the MJPEG or H264 encoding processes could have resulted in duplication of encoding the stream (poor performance) so the company limited the input methods to stop this from happening.
Because of this change, which Microsoft tried to defend but then realized the scale of the impact this change has caused, means that when a webcam tries to use MJPEG or H264, the device will freeze. If you use Skype and your webcam freezes after about a minute, this is the reason...
