About This Guide

The OCTANE XIO Personal Video option board enables a Silicon Graphics OCTANE workstation to input and output graphic and video images and record them to disk or videotape.

The OCTANE Personal Video option utilizes calls and controls in the Silicon Graphics Digital Media library, such as the Video Library. This guide explains features of the Video Library (VL) that pertain to the OCTANE Personal Video option and gives step-by-step instructions for creating VL programs that make use of OCTANE Personal Video capabilities.


This guide is written for the sophisticated video user with a background in C programming who wishes to develop video programs for the OCTANE Personal Video option board.
