While it has been under development for years, the support for video CODEC accelerators has gain a lot of traction in past year. A formal specification has now been merge into Linux Media subsystem and staging control APIs and drivers now exist. This allow for blob free HW accelerated decoding on popular SoC like Allwinner, i.MX8 and Rockchip.

In this talk, Nicolas will give an overview of the decoding process using such hardware accelerators along with an overview of the user space API and how it's used within multimedia frameworks. Nicolas will also explain the relation between this and accelerators attached to modern GPUs. This presentation would not be complete without mentioning the development of FFMPEG and GStreamer native support and their major role in the development of the the new Open Source drivers.

This talk is addressed to multimedia enthusiasts and developers curious about video decoding and the upstream effort effort to make that available to users.
