Many users report that after installing Windows 10 Anniversary Update, they have issues with webcams. Due to changes Microsoft made under the hood of the recent feature update, devices which use MJPEG or H264 codecs for streams stop working. Here is a quick fix.
In Windows 10 Anniversary Update, there are new methods for applications to access webcams, and the MJPEG and H264 encoding could have caused poor performance in systems. The company limited users to specific input methods to avoid the issue.
To unblock mentioned codecs and make your web cam working again in Windows 10, you need to apply a simple Registry tweak, as described below.
- Open Registry Editor.
- Go to the following Registry key:
HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\Windows Media Foundation\Platform
- Create a 32-bit DWORD value named EnableFrameServerMode. Even if you are running 64-bit Windows, you still need to create a 32-bit DWORD value. Leave its data value as 0.
- Restart Windows 10.
