About This Guide

The OCTANE Digital Video option board lets a Silicon Graphics® O2™ (OCTANE) workstation input and output graphic and video images and record them to disk or videotape.

The OCTANE Digital 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 Digital Video option and gives step-by-step instructions for creating VL programs that make use of the OCTANE Digital Video capabilities.


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