You can view the video in real time on the Onyx2 workstation using the OpenGL interface to copy video images to graphics. The DIVO-DVC option supports a wide variety of packing formats to facilitate easy integration of video in graphics. The DIVO-DVC option is fully integrated into the SGI Digital Media Library interfaces. Orion provides editing controls, such as in point, out point, preroll, postroll, and deck shuttle control. Also available is a variety of video file formats including QuickTime capture and playback in both field and frame mode and support for synchronized audio and video capture and playback.
Applications can open either device as two or four channels.
This vl.h file contains the main definition of the VL API and controls that are common across all hardware. The new buffering scheme is much more flexible and versatile than the older VL buffer-based scheme. DMbuffers, an abstraction of main memory, allow efficient and API-independent interchange of data between the different digital media libraries. They can also be passed between two processes without the data having to be copied explicitly. Compression in the VL is supported by adding compression-related controls on memory nodes.
