- Windows XP DirectShow Sample -- VMRXCL
- --------------------------------------
-
- Description: This application shows capabilities of the new
- video mixing renderer (VMR) that is the default video
- renderer in Windows XP. In particular, it demonstrates
- how to use the VMR in exclusive DirectDraw mode and
- how to implement a user-provided (customized) Allocator-Presenter
- for the VMR. Also, it contains useful utilities to manage
- bitmaps (as textures) and TrueType fonts for text over video.
-
- Usage:
- Upon initialization, VMRXCL asks you to specify a video file.
- The application switches to DirectDraw exclusive mode, after setting
- the display mode to 640 x 480 x 32bpp. A bitmap-based menu on the
- left side of the screen provides interactivity.
- (From top to bottom, the menu items are:
- - Show statistics
- - Pause
- - Run
- - Rotate in XY plane
- - Rotate in YX plane
- - 'Twist' non-linear effect
- - Exit
-
- Right click over the menu button to activate its text hint.
- Left click to hide text hints.
-
- Troubleshooting:
- Depending on the capabilities of your video driver, text may be disabled.
- You may also experience glitches with bitmaps applied over the video.
-
- NOTE: The speed of the 3D animation is directly related to the frame rate of
- the video file being played.
