RadeonSI UVD/VCE Video Acceleration Improvements Merged For Mesa 25.0


At the start of the new year I talked about patches improving AMD Radeon video encode/decode for older GPUs

That work to the RadeonSI Gallium3D driver's UVD and VCE support has now been merged ahead of the Mesa 25.0 code branching coming up in just over one week. This doesn't benefit the newest APU and discrete graphics that feature Video Core Next (VCN) but is just about the older pre-Raven/Navi AMD GPUs with VCE/UVD. The rework delivers on the following features finally coming to the open-source AMD driver stack for VCE/UVD: VCE and UVD: App DPB management (long term references, P hierarchy, reference invalidation, ...) Slice encoding (128 maximum slices) VBAQ Quality presets (Speed, Balanced, Quality) Min/Max QP Max frame size Intra refresh Raw packed headers
