![RADEON](/assets/categories/radeon.webp)
To the Gallium3D video acceleration state tracker is now support for "secure" video playback with AMD's Gallium3D driver (RadeonSI) for the Video Acceleration API (VA-API) interface -- the predominant video acceleration interface on Linux by the Intel and Radeon graphics stacks.
This secure video playback with the VA-API code makes use of AMDGPU TMZ (Trusted Memory Zone) and is enabled for the H.264, H.265/HEVC, and VP9 formats. The Radeon Video Core Next (VCN) block supports dealing with the encrypted content and using TMZ buffers.
This Radeon secure/protected video playback support was merged ahead of the imminent Mesa 20.3 branching, which should see its stable release in December.
