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.
Using MIPI DSI as Main Display Interface Marcel Ziswiler, Toradex AG The MIPI Display Serial Interface (DSI) is the de-facto standard display interface featured by modern higher-end SoCs. Lacking the long-term availability of discrete MIPI DSI display panels most embedded systems rely on bridge chips converting to more common display interfaces like parallel RGB, LVDS, (e)DP or HDMI. Our generic system concept relies on DSI adapter boards integrating various such bridge chips.
