And not yet for the Kodi side changes, I still have to work just a little longer on it, or else everything you play would be Dolby Vision.

I think this is where I am now. By forcing the "video/dolby-vision" mime type and the amc-dvh1 codec for HEVC streams no matter what, it triggers the Dolby Vision badge on my TV whenever i play a HEVC file.

For non-HDR movies, this severely shifts the colors and makes it unwatchable. For HDR10 streams, it also triggers the Dolby Vision badge, but the movie is actually watchable - probably because of the HDR10 base layer in mosts DV streams.

But - this makes me wonder. How can we be sure that the actual DV metadata is being used for DV streams, and not just the HDR10 base layer? The DV badge on the TV can apparently not be trusted.

Here I'm forcing:
m_mime = "video/dolby-vision";
m_formatname = "amc-hevc";

And I tried using MKTAG and MKBETAG for the if stantement but nothing. 

Basically what's left is
If (this is really Dolby Vision)
     {
        m_mime = "video/dolby-vision";
        m_formatname = "amc-hevc";
      };
      break;

And that's it. The part in bold is what I'm trying to figure out but it's late and I really need some rest.

And testing metadata... only with HD Fury or similar, which I don't have.

I tried the same approach with the MKTAG with the same results. May I ask why your'e using the amc-hevc decoder? This results in a black screen for me.
