OpenDLV Microservice to interface with Video4Linux-supported cameras

This repository provides source code to interface Video4Linux-supported cameras for the OpenDLV software ecosystem. This microservice provides the captured frames in two separate shared memory areas, one for a picture in I420 format and one in ARGB format.

Video4Linux devices with the following image formats are supported:

• MJPEG
• YUYV422

This software is based in part on the work of the Independent JPEG Group.
