- Windows XP DirectShow Sample -- VMRPlayer
- -----------------------------------------
-
- This sample demonstrates using the Video Mixing Renderer to blend
- one or two running videos and a static image.
-
- Begin by opening a primary video stream from the File menu. If you
- would like to render a second file that will be alpha-blended with
- the primary file, then open a secondary video stream from the File menu.
-
- To control size, position, and alpha blending properties of the
- primary or secondary video, choose "Primary Stream" or "Secondary Stream"
- from the VMR Properties menu. By default, the Primary stream will have
- an alpha value of 1.0 and the secondary stream will blend with an
- alpha value of 0.5. The properties dialogs are implemented as modal dialogs.
-
- You may also overlay an alpha-blended static image by opening the
- "Static App Image" option on the VMR Properties menu. Enable the
- "Display App Image" checkbox to cause the image to appear. By default,
- the image will be centered and will blend with an alpha value of 0.5.
-
- NOTE: This sample requires Windows XP (or greater) functionality
- and will exit on other systems.
-
- Usage:
- VMRPlayer </P filename>

- /P: Optional filename to automatically render and play at startup
