Gelesen habe ich, das MS das Problem kennt, irgendwann eine Lösung kommt.
Vielleicht hat hier jemand eine, denn bei Skype und ähnlichem geht die Webcam nur noch mit Ruckeln.

Does your WebCam Crash after Windows 10 Anniversary Update? Here’s How to Fix It

If your webcam has stopped working after installing recently-released Microsoft's big Anniversary Update for Windows 10, you are not alone.

With some significant changes to improve Windows experience, Windows 10 Anniversary Update includes the support for webcams that has rendered a number of different webcams inoperable, causing serious issues for not only consumers but also the enterprise.

Grund ist wohl, dass die Geräte MJPEG und H264 können, dagegen bietet die aktualisierte Windows-10-System nur unkomprimierte YUY2-Codierung.

Bisher vorgeschlagene Lösungen:


  • In der Registry für HKLM\SOFTWARE\WOW6432Node\Microsoft\Windows Media Foundation\Platform einen Key namens EnableFrameServerMode anlegen und den DWORD (32-bit)-Wert 0 setzen.
  • In der Registry für HKLM\SOFTWARE\Microsoft\Windows Media Foundation\Platform für 64Bit-Anwendungen wie UWP Skype ebenfalls einen solchen Key anlegen und den DWORD (32-bit)-Wert 0 setzen.
  • Die aktuelle Datei mfcore.dll mit folgenden Attributen versehen
attrs->SetUINT32(MF_SOURCE_READER_ENABLE_VIDEO_PROCESSING, false);
attrs->SetUINT32(MF_SOURCE_READER_ENABLE_ADVANCED_VIDEO_PROCESSING, false);
attrs->SetUINT32(MF_SOURCE_READER_DISABLE_CAMERA_PLUGINS, true);
attrs->SetUINT32(MF_SOURCE_READER_DISABLE_DXVA, true);
attrs->SetUINT32(MF_READWRITE_DISABLE_CONVERTERS, true);
attrs->SetUINT32(MF_READWRITE_ENABLE_HARDWARE_TRANSFORMS, false);
attrs->SetUINT32(MF_SOURCE_READER_DISCONNECT_MEDIASOURCE_ON_SHUTDOWN, false);
attrs->SetUINT32(MF_SOURCE_READER_ENABLE_TRANSCODE_ONLY_TRANSFORMS, false);


  • Eine alte Datei mfcore.dll aus dem Anniversary Update Version 12.0.10586.122 kopieren und die aktuelle Version 12.0.14393.10 einfügen.

Here's how to Fix Your Webcam:


The workaround is a registry hack, so if you are comfortable tweaking the registry, make the below changes. The hack is pretty simple; you just need to stick to the following instructions.

  1. Go to the Start Menu, type "regedit" and press Enter. This opens 'The Registry Editor'.
  2. Navigate to "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows Media Foundation\Platform" in the left sidebar.
  3. Right-click the "Platform" key and select New → DWORD (32-bit) Value.
  4. Name this value "EnableFrameServerMode" and set the value to "0" by double clicking on it.
These are the steps if you are using a 32-bit version of Windows 10.

If you are using a 64-bit version of Windows 10, you will need to navigate to "HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\Windows Media Foundation\Platform" in the left sidebar and follow step 3 and 4 mentioned above.

Now close the registry editor and just re-launch the application in which your webcam was freezing. They should now work normally – no reboot, no sign out required.

When Microsoft actually fixes the issue after a month, just revisit the same location in the registry editor and delete the "EnableFrameServerMode" value you added to undo this change.​

 
Für Win64:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows Media Foundation\Platform]
"EnableFrameServerMode"=dword:00000000
