More and more graphics and video processing units of embedded SoCs are supported by drivers that are developed in the open as free software. This makes it easier than ever to build interesting hardware accelerated video streaming applications on Linux using only open source components, such as GStreamer, Mesa, V4L2, and Wayland - without the need for vendor patches or binary-only libraries.This talk will cover capturing, encoding, streaming, decoding, compositing, and displaying video as efficiently as possible using an i.MX6 SoC with Etnaviv graphics and V4L2 video capture and codec drivers as an example system.
