🎛️ Mpv Configuration

Enhance your Stremio experience by customizing the MPV player settings. Below are the key configuration files and guidelines to help you get started:

• 📁 mpv.conf Location

  • The mpv.conf file can be found in the following location:
    • Installation Path: %localAppData%\Programs\LNV\Stremio-5\portable_config\mpv.conf
    • Shaders Folder: Located within the installation directory ..\Stremio-5\portable_config\shaders.
    • Latest Portable Config: Latest portable config can be found here.

• 🎹 Usage example of mpv.conf for DV Content:

  # MPV Conf for DV Content
  vo=gpu-next
  gpu-api=vulkan
  target-colorspace-hint=yes
  

⏳ Note: Any other configuration files can be just dropped into %localAppData%\Programs\LNV\Stremio-5\portable_config as this is the mpv config-dir like input.conf. scripts or scripts-conf

• 🎹 Usage example in input.conf using Anime4k:

  # Optimized shaders for higher-end GPU
  CTRL+1 no-osd change-list glsl-shaders set "~~/shaders/Anime4K_Clamp_Highlights.glsl;~~/shaders/Anime4K_Restore_CNN_VL.glsl;~~/shaders/Anime4K_Upscale_CNN_x2_VL.glsl;~~/shaders/Anime4K_AutoDownscalePre_x2.glsl;~~/shaders/Anime4K_AutoDownscalePre_x4.glsl;~~/shaders/Anime4K_Upscale_CNN_x2_M.glsl"; show-text "Anime4K: Mode A (HQ)"

⏳ Note: Some keys might not work as key presses are converted from js event.codes to literal values for mpv

• 🔡 Subtitle Customization:
  • Subtitles can be full customized in the mpv.conf by adding the following:

    # Adjust as needed - 
      sub-font="Comic Sans MS"
      osd-font="Comic Sans MS"
      osd-font-size=43
      sub-font-size=43
      sub-color=#e1fe00
      sub-font-size=43
      sub-color=#ffffff
      sub-font-size=43
      sub-border-color=#000000
      sub-border-size=2
      sub-shadow-offset=1
      sub-shadow-color=#000000
      sub-spacing=0
      sub-margin-y=41
      sub-line-spacing=0
      ass-line-spacing=0
      # To overwrite .ass subs use sub-ass=no or just use F2 to cycle subtitle modification levels
    

  • Stremio by default overwrites the following:

        # These 3 options are set using the web ui under the settings page
        'subtitlesTextColor': 'sub-color',
        'subtitlesBackgroundColor': 'sub-back-color',
        'subtitlesOutlineColor': 'sub-border-color',
    
        # Affected mpv sub settings by this are:
        sub-color
        sub-back-color  # + Alias sub-shadow-color
        sub-border-color # + Alias sub-outline-color
    
        # All these need to be set via the web ui instead
    

⚙️ Start Arguments

Use these extra arguments when launching the application:

Argument	Example	Description
--webui-url=	--webui-url=https://web.stremio.com/	Loads web ui from https://web.stremio.com/
--streaming-server-disabled		Disable auto start of streamio-server, Default behaviour in prod
--autoupdater-force-full		Forces Autoupdate to always do a full-update rather than partial
--autoupdater-endpoint=	--autoupdater-endpoint==https://verison.mydomain.com/	Overrides default checking endpoint for the autoupdater
