Radeon Gallium3D Fixes Up 10-Bit HEVC Video Decode Support

Written by Michael Larabel in Radeon on 3 January 2020 at 12:23 PM EST. 16 Comments

Hitting Mesa 20.0-devel a short time ago were a set of patches to the Radeon Gallium3D video code for fixing 10-bit HEVC video decode support.

The AMD Radeon open-source Linux graphics driver has supported 10-bit HEVC video decode acceleration using the P016 format, but that has caused problems with GStreamer-based software while working fine for the likes of MPV and FFmpeg.

Now with Mesa 20.0-devel, the P010 format is used as the default buffer type for addressing that situation and should make all video decode solutions.

This Radeon 10-bit HEVC video decode change was made as part of this merge request honored today for Mesa Git and could be back-ported to stable series soon.
