I am curious about the current state of playback of Dolby vision files. I know that the Nvidia shield tv can playback videos and there is the movies and tv windows app that can tone map to SDR if you download the Dolby experience app. But has there been meaningful progress for vlc mpv potplayer or direct playback from pc to tv? It seems like Dolby Vision has won over HDR10+ in the HDR video format war.

There’s good recent progress in that Matroska (mkv) can now contain Dolby Vision metadata. There’s also progress with public tools that can process some of this metadata and convert between Dolby Vision profiles, say from profile 5 (hardcoded bitstream) to profile 8 (enhancement bitstream) so that you can have HDR10 fallback for scenarios where Dolby Vision won’t work. Unfortunately there doesn’t seem to be any PC playback progress yet. However in addition to the Nvidia Shield there are Chinese devices like the Zidoo Z9X [1] which show that the work can be done. The PC space is still waiting for a champion though. —- [1] https://www.zidoo.tv/Product/index/model/Z9X/target/VEMg6VRC2%2B9KKmVViAFMcQ%3D%3D.html https://www.zidoo.tv/Product/index/model/Z9X/target/VEMg6VRC...

>and there is the movies and tv windows app that can tone map to SDR if you download the Dolby experience app There is? I searched around and couldn't find it. As for tonemapping on open source players, there's madvr, but it's imperfect compared to the official SDR release.

  I might be remembering wrong, it might also need the HEVC windows 10 app. It is a paid app but mine came free with my laptop. I know the main thing is using the Movies and TV app. The DV app is called Dolby Vision Extensions app. https://thewincentral.com/microsofts-new-app-dolby-vision-extensions-now-available-in-google-play-store/ https://thewincentral.com/microsofts-new-app-dolby-vision-ex... Indirect link because the windows store link looked horrible when I tired copy pasting. You might be able to get the HEVC app free if you Google, but I haven't tried it myself.

    >HEVC windows 10 app Unless you can link to the specific "HEVC windows 10 app", I'm pretty sure you're referring to "HEVC Video Extensions", which is just a codec pack for decoding HEVC files. >DV app is called Dolby Vision Extensions app The linked article says that you need a "Dolby Vision licensed device"? That suggests it might need some sort of calibration for it to work?

      I haven’t verified this myself, but I’ve seen a bunch of people on reddit claim success with the following combo: * Movies and TV player * HEVC extension * Dolby Access app * Dolby Vision extension Additionally Dolby Vision works on Windows with a few big budget games. Thus the pipeline exists and can be used. It’s just obscured by proprietary secrets.
