SchemaReader sample requires Windows Media Player 11

The SchemaReader sample, which is part of the Windows SDK, requires Windows Media Player 11 to be installed.

Online store plug-in wizard must be installed manually

The Visual Studio Registration utility does not install the online store plug-in wizard as stated in the Windows Media Player SDK documentation. If you want to use the online store plug-in wizard, you must install it manually.

Perform the following steps to install the wizard manually.

  1. Using Windows Explorer, locate the folder where you installed the SDK. Search for the subfolder named \Wizards\Services.


    C:\Program Files\Microsoft SDKs\Windows\vx.x\Samples\multimedia\WMP_11\Wizards\Services
  2. Copy the following three files to a temporary folder:
    • wmpservices2005.vsz
    • wmpservices.ico
    • wmpservices.vsdir
  3. Change the file name of the copy of wmpservices2005.vsz to wmpservices.vsz.
  4. Using Notepad, edit wmpservices.vsz. Locate the following line:
    Param="ABSOLUTE_PATH = <path to wmpservices directory goes here>"

    Change the value for ABSOLUTE_PATH to the path where the wizard files were copied from.


    Param="ABSOLUTE_PATH = C:\Program Files\Microsoft SDKs\Windows\vx.x\Samples\multimedia\WMP_11\Wizards\Services"
  5. Locate the subfolder named vcprojects where you installed Visual Studio. Paste into this folder the three files that you copied earlier. The wizard is now installed.

SAMI style is not applied by default when using Media Foundation

If Windows Media Player uses the Windows Media Format SDK or DirectShow to render a file and the SAMIStyle property is not set, the first style defined in the SAMI file is used by default. If Windows Media Player uses Media Foundation to render a file and the SAMIStyle property is not set, no style is applied to the caption text.

Microsoft is aware of this issue and is working to provide a resolution in future releases.

Captions might not be displayed in closecap sample

In Windows Vista, the closecap sample might not display captions.

You can fix this problem by editing the following line in the ccsample.smi file

.ENUSCC {Name:'English Captions' lang: en-US; SAMIType:CC;}

Insert a semicolon after 'English Captions'. The edited line should look like this.

.ENUSCC {Name:'English Captions'; lang: en-US; SAMIType:CC;}

To find the ccsample.smi file, locate the directory where you installed the Windows SDK, and navigate to Samples\multimedia\WMP_11\media.

Player control can cause an exception with Visual Basic .NET 2002

If you use Microsoft Visual Basic .NET 2002 to create a project that embeds the Windows Media Player ActiveX control, the project may raise an exception. To avoid this issue, you must first remove (or comment out) the following line of code from the code that is generated automatically by Visual Basic .NET:

Me.AxWindowsMediaPlayer1.enabled = True

Windows Media Player 6.4 compatibility issues

You may experience changes in the behavior of the Windows Media Player 6.4 ActiveX control after installing Windows Media Player 11. For more information about compatibility, see the Windows Media Player 6.4 SDK on the Microsoft Web site.

64-bit development not supported

The Windows Media Player SDK supports 32-bit development only. 64-bit development is not supported.
