Supporting Hardware Codecs in a Linux System - Lecture

Explore the intricacies of supporting hardware codecs in a Linux system through this informative 35-minute conference talk. Delve into the v4l2 subsystem, the Linux kernel framework of choice for supporting hardware controllers in modern multimedia-oriented ARM SoCs. Follow the speaker's journey through the changes required to support codecs in the v4l2 stack, the challenges encountered during driver development, and the issues faced in making hardware decoding useful for general-purpose video players like Kodi, gstreamer, and VLC. Gain insights from the presenter's experience developing a v4l2 driver for the Allwinner video encoder/decoder controller on a mainline kernel. Learn from Maxime Ripard, an embedded Linux engineer and trainer at Bootlin, who has pioneered Allwinner SoC support in the official Linux kernel and co-maintains this platform.
