Matrix API 2.0

Real-time audio/video processing in software

DekTec Matrix API is a set of DTAPI classes for the real-time processing of audio and video data received/transmitted with DekTec SD-, HD- and 3G-SDI input and output interfaces. It abstracts from threading, memory management and hardware complexities allowing your application to focus on processing the video, audio and auxiliary data
