GStreamer and ROS - A Tale of Two Messaging Frameworks

Explore the intersection of GStreamer and ROS in this 47-minute conference talk from linux.conf.au 2022. Dive into the similarities and differences between these two message-oriented software frameworks for high-performance real-time systems. Learn how GStreamer's multimedia processing pipelines and ROS's robotic module integration can be combined to create a more flexible free software ecosystem. Discover the design patterns of both frameworks, their applications in image processing, and potential solutions to common ROS issues. Gain insights into pipeline elements, diagrams, and the rapid adoption of new infrastructure code. The talk concludes with a demo, discussion of other features, ROS nodes, and a Q&A session covering simulation tools and launch syntax.
