FIX: You cannot play a Windows Media file on a Windows Embedded CE 6.0-based device if the video render of the device uses the YV12 format to render the media file

You cannot play a Windows Media file on a Windows Embedded CE 6.0-based device if the video render of the device uses the YV12 format to render the media file. When this problem occurs, the application screen will not display anything unless you have set a customized error message.

Additionally, if you play the file in Windows Media Player, you receive the following error message in the Debug output window.

CWMVideoDecMediaObject::InternalProcessOutput - WMVideoDecGetOutput failed - returned 0x5

You receive the error message when you perform the following actions:
  • You use Kernel Independent Transport Layer (KITL) to connect the device in Windows Embedded CE 6.0 Platform Builder
  • You enable the debug zone of the wmvdmod.dll module
This problem occurs because the Microsoft DirectX Media Object (DMO) miscalculates the width of an image when the YV12 format is used as the output format. Therefore, the file cannot be rendered.
