Enabling AMD 2D Hardware Acceleration for Video API and Applications

links:none on file
slides:none on file

AMD brings up its VPE 2D fixed‑function path with kernel driver plumbing and a shared C VP lib that builds and submits the VPC/VPP command stream; user‑space work adds VA-API and Mesa integration and patches to mpv so decoded YUV surfaces take the 2D path. Measurements on a laptop show end‑to‑end playback power falling from about 20 W to ~9.5 W. The implementation uses VCN for decode, VP for post‑processing, and works with existing VA calls.
