DIVE (located in \TOOLKIT\SAMPLES\MM\DIVE) illustrates the use of the direct interface video extensions. DIVE provides optimized blitting performance for motion video subsystems and applications that perform rapid screen updates in the OS/2 PM and full-screen environments. Using DIVE interfaces, applications can either write directly to video memory or use the DIVE blitter. The DIVE blitter takes advantage of acceleration hardware when present and applicable to the function being performed.

Note: The DIVE sample requires OS/2 Warp Version 3 or later in order to execute properly. The files for the samples will be installed when the samples are selected, but Workplace Shell objects will not be created for them if the installed operating system is not OS/2 Warp Version 3 or higher.

The OS/2 Warp color support defaults to 16 colors. This means that your setup needs to be updated; otherwise, the DIVE sample will not run.

The maximum window size of this sample has been limited to 640x480 because larger window sizes can cause excessive swapping on machines with less than 16MB.

Hardware requirements:

• Computer capable of running OS/2 Warp
  
• SVGA (a screen mode of 640x480x256 constitutes a minimum SVGA system)

Software requirements:

• OS/2 Warp 
  Multimedia support
  
  Software motion video
