Dolby Vision playback possible with MPV (without HDR profile fallback)?

[definatelynotlhero]

I've got a Dolby Vision compatible PC monitor. Does MPV have a way to playback DoVI directly? Like for example when I playback in Windows Media Player I get the Dolby Vision logo and the monitor Dolby Vision settings work. Once I use MPV the monitor fallbacks to the HDR profiles.

Nop, both Netflix app, and Media Player display Dolby Vision logo on the video itself (not just the logo when you enable dolby vision device profile) and playback Dolby Vision as it should be.

It is possible to switch display to Dolby Vision mode using GPU vendor provided API. Both NVIDIA and AMD provides that. Though, it is likely overkill for mpv. Also the fact that you see DV logo, doesn't mean much about the actual quality and content being passed on.

Example of AMD API https://gpuopen-librariesandsdks.github.io/ags/group__general.html#ga3cdae9f8df77d94be6d9a62ddb066a73

Dolby Vision requires a 8888 UNORM swapchain.

I'm also not sure, what format the data should be forwarded in this case and there is not really a way to pass dynamic metadata to the display. So it looks like Dolby Vision enabled mode, but works without much of the dynamic part, although it might be that data should be preprocessed somehow.

I don't know, the information is scarce on this topic and I'm not willing to really go out of my way to implement some fragile vendor specific format signaling. I'm not payed enough for such changes.

I've checked UE code, they enable only Mode_HDR10_scRGB mode.

And marketing aside, there is not much to be gained from Dolby Vision output compared to the properly configured HDR10 output for your display, which is already possible in mpv.

There is definitely a difference in color and quality when using the DoVI files where logo appears on the content in either Netflix\Media player compared to the HDR version in MPV or swapping my monitor to the HDR profiles. My desktop monitor brings the same 3 profiles that usually appear on the TV (DV Dark, Bright and Gaming). Also I am quite sure the DoVI works, because I use it all the time on my Sony A95L TV, and when comparing the DV Dark for example in the content on Netflix, it looks like the right format that I am used to seeing on the TV.

But I understand your concerns @kasper93. I hope to see in future in MPV support for proper DV playback, nowadays most of the Netflix content (and other platforms) is in the DoVI format, and on my living room TV, I am pretty much always watching DV dark. They look the best to me. However it is true, that Dolby is very closed, and they are annoying when it comes to fixing things.
