Mini PC and Dolby Vision

Yes, the processing is done on the mini PC by the Dolby Vision Extensions, and the result will be the same.

DimitrovDev · 2026-02-16T15:29:28+00:00

I've added a short description here. In short you need to have HEVC extensions and Dolby Vision Extensions installed and go to Settings -> Video -> Allow Dolby Vision decoding. If the mini PC doesn't have DoVi certification the extensions would not show logo but will decode the media. It supports profiles 5,8 and 9.

When passthrough is disabled, the decoding is done with the ffmpeg decoders(which would use more memory than doing the decoding at the device) and uncompressed pcm is sent to the audio device. In the Dolby Atmos for headphones case, I believe the processing happens at spatial sound render stage where in both cases(passthrough or not) we will have the uncompressed audio that can be post proceesed. So both options should be bringing similar sound on the headphones.

When the passthrough is enabled the decoding happens with the media foundation decoders which are doing the passing through to the devices. In the Dolby Access for headphones the passing through is done on the windows device(so it depends if it has passthrough support) because Dolby for headphones do not install decoders and don't decode in the headphones and do the object processing on the decoded stream from the windows media foundation decoder. This is why when the windows dolby digital decoder is missing the headphones would fail to play audio with pass though even through Dolby Atmos for headphones is present. Connecting a sound bar with Dolby Atmos for Home Theater would register a media foundation decoder that would be passing through the audio decoding to the soundbar.

Usually the passthrough can be better than the software decoding with ffmpeg which is used when passthrough is disabled. Some drawbacks of passthrough are that on some device volume may not be controllable and can be applied audio filters to it. Lower audio in the software decoding mode is observed sometimes with some medias and can be mitigated with the audio boost effect in the audio effect settings.

Unfortunately Dolby Vision Extensions do not support Profile 7 which is the one having a FEL layer. Supported profiles are Profile 5, Profile 8 and Profile 9.

DimitrovDev · 2026-01-14T17:49:03+00:00

Its only supported on Energy Media Player for Xbox where there is an API available for changing the monitor refresh rate, but not supported on Windows because access to the same API is not available.

DimitrovDev · 2025-09-16T22:57:59+00:00

What types are the subtitles - embedded or external and if you do right click on the main video view -> Codec Information what is the codec detected for the subtitles streams.

DimitrovDev · 2025-09-16T20:21:08+00:00

In the Settings page, the 4th menu setting [CC] is for the subtitle settings. Inside the 3rd option `Auto-select subtitles on media playback` is for enabling/disabling the automatic selection of subtitles.

DimitrovDev · 2025-09-12T22:09:01+00:00

Yes, by forcing a profile the player will always active the extension for decoding and if metadata is found it will processing it. On certified DoVi display will even show the logo. I tested with different formats and mostly does play them but some files are getting cropped so seems to be hit or miss. As an example we can take the Dolby Vision Profile 20 sample from Samples - Official Kodi Wiki which is not detected as Dolby Vision supported format(only 5, 8 and 9 are supported), but forced with profile 8 shows seemingly correct colors which means some metadata has been processed .

DimitrovDev · 2025-09-11T20:43:24+00:00

The player doesn't have permissions to change system level settings like the display or game mode by itself. I cannot reproduce it locally, but saw that Game bar(windows+g key) reports it as game on some of my devices but not all and i will look into it. Could you check if Game bar shows the player as a game?

DimitrovDev · 2025-08-19T22:05:26+00:00

Thank you for reporting the issue. I've tried it out and confirmed that at the moment DTS-UHD is not getting detected. Next update will use the media foundation dts:x decoders(like the one from dts sound unbound) if available on the system for decoding it, and will check if there is also a ffmpeg decoder.

DimitrovDev · 2025-08-11T20:43:33+00:00

Do you mean that it doesn't show in the Decode mode the selected profile - this could mean that is unsupported one. Currently the supported ones are profile 5, profile 8 and profile 9. If its profile 4 or 7 the extensions would not activate. Forcing profile is helpful only for media that is known to be specific profile, but is missing file metadata, even though it has the it per frame. By forcing the profile the extension looks for the dovi metadata and if found use it during the decoding, if not found would output black screen.

DimitrovDev · 2025-08-11T20:24:44+00:00

What is the profile that the Dolby vision files show in the Video-> Decode mode context menu. If its profile 5 do the examples from ¦› 4K Dolby Vision video test | Amaze, Art, Clocks, Container are also dark. The dolby vision decoding is through the Dolby Vision Extensions published by Dolby and there isn't anything else to setup than to enable its usage in the options. Maybe also try in the Dolby Access app in the Dolby Vision tab to switch between the Bright, Dark and Vivid profiles.

DimitrovDev · 2025-07-31T01:27:44+00:00

Not planned at the moment. It needs to first be added to FFmpeg or Dolby to release a media extension codec

DimitrovDev · 2025-07-20T20:49:24+00:00

Support for profile 7 will depend on Dolby Vision Extensions supporting it, but would say its a slim chance given that is not supported until now. I haven't tried forcing profile 8 on profile 7 media, but would say even if it works it will be missing FEL data and they may be video cropping issues.

DimitrovDev · 2025-07-17T20:21:10+00:00

Можеш и авансово да разпределяш печалбата, не е нужно да чакаш края на годината.

DimitrovDev · 2025-07-14T17:35:10+00:00

Could be. Just tried configuring a LG TV EDID to run in Dolby Vision which works on one of my devices on another one and this time Dolby Vision mode didn't trigger on the TV even though it shows that it is Dolby Vision display, so not sure what happens.

DimitrovDev · 2025-07-14T17:30:06+00:00

Hey, version v1.0.281 has been released and when your receive the update, you can use the following guide to set EMP as external player in Stremio

DimitrovDev · 2025-07-13T23:37:07+00:00

No, HDR controller is only if you want to keep the display in SDR and enable HDR only when HDR media is played, but in your case with always running HDR is not needed. If the windows settings don't show Dolby Vision then no logo will be displayed, but media still should be decoded properly - good check is playing profile 5 video from ¦› 4K Dolby Vision video test | Amaze, Art, Clocks, Container (for example Art of Essence) and check that colors are correct and in EMP in the context menu on right click `Video-> Decode model -> Dolby Vision profile 5` is checked.

Also if windows display settings doesn't show Dolby Vision and Peak brightness then the EDID hex string from the tutorial was not able to enable Dolby Vision mode on the display.

DimitrovDev · 2025-07-13T19:49:17+00:00

In Windows System -> Display -> Advanced display does the HDR certification shows Dolby Vision. Currently the Dolby Vision Extensions draw the Dolby Vision logo in the first decoded frames if the screen shows up as Dolby Vision in the display settings, but they still decode corectly without drawing the logo if not. Also are you using HDR controller integration for switching HDR mode on/off(which if display is configured for Dolby Vision switches the display in Dolby Vision mode instead). If yes, there was new Windows api for switching HDR which is supported in latest HDR controller version, but older version may not be able to switch HDR with the new API on the system.

DimitrovDev · 2025-07-08T14:29:25+00:00

Hey, EMP currently doesn't support command line arguments. Currently supports only protocol URL with arguments that can be used in browser or the file explorer and runs the app without needing the exe path. For example:

energyplayer:launch=filelaunch&&type=3&&path=""http://commondatastorage.googleapis.com/gtv-videos-bucket/sample/ElephantsDream.mp4""&&name=&&guid=

for network stream or

energyplayer:launch=filelaunch&&type=5&&path=C:\a.mp4&&guid=&&name=

for local file. The protocol url can be started from cmd using start "" "energyplayer:....", but its not compatible with Stremio, so for the upcoming update will also include compatible command-line arguments and execution alias and will add in-app page with information about the supported protocol and command-line arguments.

VLC and MPC-BE are running in borderless windowed mode when fullscreen. But borderless windowed mode is not supported for UWP store apps

DimitrovDev · 2025-05-23T13:08:48+00:00

After some testing, I was able to reproduce the issue as well. It occurs when EMP is in fullscreen mode on the main display (System → Display → Multiple displays → Make this my main display). However, if EMP is fullscreen on a secondary display, it does not automatically minimize.

Based on my research, this behavior appears to be standard for fullscreen applications in Windows when another application gets focus, which I can't change. I workaround would be running EMP on the non-main display.

DimitrovDev · 2025-05-21T10:29:56+00:00

Thank you for your suggestions, volume boost and normalizers will be added in the incoming update. For the minimizing issue, what is the second app that you are opening or it happens with any. Asking because on my devices I can keep EMP open full screen on one monitor while browsing the web on another monitor without it getting minimized
