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.
And:
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.
Microsoft is hoping to deploy a fix for this problem next month. If you’re experiencing webcam issues after the Anniversary Update and you can’t wait until then, check the bottom of the article linked in the above paragraph. One resourceful user has found a registry hack that should make your webcam usable again.
