Thanks, your guides worked quite fine (also your permanent EDID one) !
the only difference being using libva2 package instead of libva, no libnfs8 in ubuntu's ppa. a kodi-bin not needed.

Do you think it would be possible to add something like VAAPI sharpness filter to Kodi?
(just googled this, but not really sure if it is related - https://ffmpeg.org/pipermail/ffmpeg-deve...23714.html)
or is there any other way doing shaprness post-processing in Kodi.

Currently I'm using nVidia VDPAU with VDPAU Sharpness, Intel VAAPI MCDI looks great, but I find other materials (non-interlaced videos) image quality little bit soft compared to nVidia.

 MCDI does deinterlacing. This does absolutely nothing with progressive content.
We decided some time ago that we don't want to implement decoder specific postprocessin of features that can be done in the renderer (OpenGL) and would then be available for all others. If you want to hack in the sharpness into VPP it's just three lines of code. So tell use about your results.
