Explore efficient zero-copy video streaming techniques for embedded systems in this 39-minute conference talk by Michael Tretter and Philipp Zabel from Pengutronix. Discover how to leverage open-source components like GStreamer, Mesa, V4L2, and Wayland to build hardware-accelerated video streaming applications on Linux without proprietary patches or binary-only libraries. Learn about capturing, encoding, streaming, decoding, compositing, and displaying video using an i.MX6 SoC with Etnaviv graphics and V4L2 video capture and codec drivers as a practical example. Gain insights from Michael Tretter, a software engineer specializing in Linux graphics infrastructure, and Philipp Zabel, a kernel developer, as they demonstrate the power of free software drivers in supporting graphics and video processing units on embedded SoCs.
