Originally introduced in 2019, the Video4Zephyr (v4z) APIs provided a foundational interface for interacting with video devices in Zephyr. However, with minimal changes over the years, their limitations have become apparent—especially as video hardware grows more complex and camera-based applications become increasingly demanding.

This talk presents the current status of v4z, hightlighting recent improvements as well as sharing ongoing and upcomming works which turns the v4z from a simple driver API into a robust video subsystem. We’ll cover the devicetree video port/endpoint mechanism, a unified video control framework, enhanced buffer management, and support for memory-to-memory (m2m) devices, etc. These efforts aim to shift commont functionality and logic into the subsystem itself, significantly reduce the burden on driver developers - bringing the Zephyr’s video stack closer to a mature multimedia framework.
