But quietvoid wrote it already works for him.

I could have read it wrong, but I interpreted what he said as the ffmpeg patch is working as he see's the side data reported in the log however he doesn't yet get Dolby Vision out from Kodi to the TV so something is still missing. If something is indeed still missing in order to get Dolby Vision out, then one I noticed when looking at the Plex version of ffmpeg is that they are using an older version, so perhaps something may have changed in one of the API's in the newer version that Kodi uses that needs to be taken into account somewhere.
