Branch details for the same as below: > https://github.com/xbmc/xbmc/tree/feature_drmprime-vaapi I have now re-tested this v9 series (non i915 parts) on Rockchip RK3328/RK3399 using Kodi HDR PR [1] and dw-hdmi patch [2]. Kodi sets the HDR output metadata property with metadata retrieved from FFmpeg, my LG OLED B7 correctly activates/deactivates HDR/HLG mode depending on video file played.
