How to activate HDR 10 and Dolby Vision on Emby Theater and Windows 10

[nicko84 71]

I've no Dolby Vision and maybe no HDR10 (?) on ET 3.019 and Windows 10.

How can i have both ?

Do i need a specific mpv.conf ?

Thanks for your help.

NB : Dolby Atmos works fine

PS : on Android and Fire Stick App Dolby Vision is good but Atmos is not

HI, did you configure HDR in windows settings?

[nicko84 71]

Hello Luke,

Yes i did it but no change i think (?).

How can i be sure that DV or HDR10 are decoded by ET ?

In the video settings, change video output to gpu-next and leave hardware acceleration on auto

DV will be tone mapped but the picture will appear correct and for HDR10, you'll notice the picture will have great contrast and color depth.

Hi, no, but this would be a good idea to add.

If it's HDR10 the stats will say bt2020, DV is different and the stats will probably show it as bt709, because of the way it's read. But if the system is in HDR10, DV will be reduced to static metadata and mapped to bt2020.

Hello,

Windows HDR is HDR 10 ?

So videos in DV will always be reduced to HDR10 ?

If yes, ET never display in DV on Windows ?

Hello Luke,

Do you think you could add it to stats soon ?

A beta ET is it available ?

[Luke 42077]

It’s possible for future updates to the app. Thanks.

Windows HDR is all forms of HDR, but the player in Theater (mpv) only supports DV by tone mapping and not forwarding the metadata.

Thanks for your answers both !

Hello,

My last (but not least) experience with ET and HDR10/Doby Vision (and Dolby Atmos) :

-ET on Desktop : HDR10 OK and DV KO (seen as HDR10) / Dolby Atmos OK

-ET on Google TV : HDR10 and DV OK / Dolby Atmos KO

-ET on Shield TV Pro : HDR10 and DV OK / Dolby Atmos OK

Hello,

Does mpv.conf with gpu-next is running good ?
Or is it better to put auto in video output and mpv.conf in hardware acceleration and deal with gpu-next (and other mpv parameters) into the mpv.conf ?

Have you tried selecting gpu next in the UI?

[nicko84 71]

Yes and it's running good but in this case can input mpv.conf in hardware acceleration instead of auto ?

If you want to use your conf for hardware acceleration,  just set it to 'unset' in the Theater settings. 

Or are you asking about video output/gpu-next, which is not hardware acceleration? My recommendation for Luke, was to use gpu-next as the default.
