4.1.5GDI Options

The following option is a GDI option that indirectly affects the display driver. The display driver does not read this key. Instead, it affects how GDI calls the display driver. For more information, search for “ForceGRAY16” on www.microsoft.com\msdn.

[HKEY_LOCAL_MACHINE\System\GDI]

ForceGRAY16 <DWORD>

This key controls GDI anti-aliasing.

4.1.6Video Options

The display driver supports a number of options to control video rendering. See the 2D Graphics Options section above for additional options that affect video rendering.

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\DirectX\DirectShow\Video Renderer]

The following settings affect the direct show video renderer.

MaxBackBuffers <DWORD>

This setting determines if single, double, or triple buffering is used. This is the number of back buffers, so please keep in mind that you have a primary buffer as well. Setting this to 0 gives you single buffering, 1 – double buffering, and 2 – triple buffering.

KeyColor <HEX>

This setting configures the color key. This value is in R-G-B format in HEX and corresponds to the color drawn on the frame buffer in areas where the video overlay is to be positioned.

Note: The key can be changed at run-time, but Media Player must be restarted to pick up the change. In cases where this is being used to debug an issue, choose a bright color. The default color tends to be dark grey or black, which can hardly be differentiated from the video image.
