Since 2021, the Linux kernel has been preparing to support encoding/decoding the royalty-free AV1 codec. It began with a “request for comments” patch series by Collabora’s Daniel Almeida for implementing the stateless AV1 user-space API within the media subsystem. The first uAPI tentatives needed seven versions on the mailing list before finally being considered stable in June 2023. The latest Linux kernel (v6.5) includes patches that enable support for AV1 uAPI as well as two stateless video decoders: one for the Rockchip RK3588 and one for MT8195, a MediaTek SoC.
