2017 is the Year of the Linux Video Codec Drivers
Talkat Embedded Linux Conference + OpenIoT Summit North America 2017 · on Thursday, 2017-02-23· at 10:00· Broadway III/IV·
summary
Linux kernel now supports real codec drivers: V4L2 gains let stateless hardware be controlled with standard APIs and ChromeOS proves it works without OpenMAX. The implementation uses multi‑plane buffers and the mem2mem framework for data, a userland controller via libv4l plugin to parse headers and reorder frames, and a new request API (FD-based, groups controls+buffers) to tie parameters to specific frames. Request API patches are WIP with a next submission due mid‑March.
