Great Progress on this Tiben! Just did some testing with the latest version. Both madvr and mpc renders are working for me. Tested with HDR and non HDR content. Native 4k and 1080p on an HDR TV (Windows HDR on for the TV).

Bugs i noticed:

• Can't get subtitles to work with madvr
  
• Subtitles with MPC are messed up (Green color, strange Font and way to big)
  
• Sometimes when i stop playback the menu colors are washed out in the menus. Probably some HDR issues?? I think this has been mentioned before in this thread somewhere.
  

Missing features:

• I can now add external filters. YAY!! However even though i selected AviSynth filter as external filter smooth video project (SVP) does not kick in to do its magic :-( AviSynth also does not show up in the filters list when i go to the Video options menu during Playback. Only the three LAV filters show up (using mpc renderer)

Do you think libplacebo will get as good as madvr is regarding dynamic tonemapping? This is the only reason I’m using madvr. Upscaling is as good with the other scaler in my opinion.

Im not sure i cannot really test and improve on it because from my understanding dynamic tonemapping is a lot more important on projector screen. I have a projector and a screen but its 15 years old 720p not hdr. And even if i get a projector i would need to put a lot of time into it to get something very similar

I will fix the madvr subtitles didnt think to test it.
For mpc can you send me in pm a print screen of the mpc subtitles with the osd with mpc osd style.
The playback menu yes its a hdr issue i don't revert to the original non hdr color i will fix it in future release

Your test with avisynth send me a debug log with your pm so i see what is happeing so i can test on my side and fix it
