elm-mpv-webui

...is a web based user interface with controls for the mpv mediaplayer.

Written in elm, elm-ui and lua.

Usage

Elm

Install elm https://guide.elm-lang.org/install/elm.html then run:

$ git clone https://github.com/rofrol/elm-mpv-webui
$ elm make webui-page/src/Main.elm --output webui-page/webui.js

Lua

Tested on Ubuntu 19.10.

$ sudo apt install lua5.2 lua5.2-dev luarocks
$ sudo luarocks install luasocket

Install in mpv

$ mkdir -p ~/.config/mpv/scripts
$ cd ~/.config/mpv/scripts
$ ln -s elm-mpv-webui/webui.lua .
$ ln -s elm-mpv-webui/webui-page/ .

Alternatively you can also use the --script option from mpv or add something like scripts-add=/path/to/elm-mpv-webui/webui.lua to mpv.conf.

find all video files in directory and play them with mpv

Use mpvdir script from this repo:

mpvdir /path/to/sth <mpv options>

Web browser

You can access the webui when accessing http://127.0.0.1:8888 or http://[::1]:8888 in your webbrowser.

By default it listens on 0.0.0.0:8888 and [::0]:8888. As described below, this can be changed.

Options

Options can be set with --script-opts with the prefix webui-.

port (int)

Set the port to serve the webui (default: 8888). Setting this allows for running multiple instances on different ports.

Example:

webui-port=8000

ipv4 (bool)

Enable listening on ipv4 (default: yes)

Example:

webui-ipv4=no

ipv6 (bool)

Enable listening on ipv6 (default: yes)

Example:

webui-ipv6=no

disable (bool)

Disable webui (default: no)

Example:

webui-disable=yes

logging (bool)

Log requests to STDOUT (default: no)

Example:

webui-logging=yes

audio-devices (string)

Set the audio-devices used for cycling. By default it uses all interfaces MPV knows of.

You can see a list of them with following command:

mpv --audio-device=help

Example:

webui-audio-devices="pulse/alsa_output.pci-0000_00_1b.0.analog-stereo pulse/alsa_output.pci-0000_00_03.0.hdmi-stereo"

Authentication

There is a very simple implementation of Basic Authentication. It will be enabled, if a file .htpasswd exists in the same directory as webui.lua. The file needs to contain data in the following format:

user1:password1
user2:password2

Only plaintext .htpasswd entries are supported.

Screenshots

Endpoints

You can also directly talk to the endpoints:

All POST endpoints return a JSON message. If successful: {"message": "success"}, otherwise, the message will contain information about the error.

/api/status

metadata contains all the metadata mpv can see, below is just an example:

{
    "filename": "big_buck_bunny_1080p_stereo.ogg",
    "duration": 596,      # <-- seconds
    "position": 122,      # <-- seconds

    "remaining": 474,     # <-- seconds
    "sub-delay": 0,       # <-- milliseconds
    "audio-delay": 0,     # <-- milliseconds
    "fullscreen": false,
    "metadata": {},       # <-- All metadata available to MPV
    "track-list": [       # <-- All available video, audio and sub tracks
        {

            "type": "video",
            "src-id": 0,
            "albumart": false,
            "default": false,
            "forced": false,

            "demux-w": 1920,

        },
        {

            "demux-channels": "stereo",
            "demux-samplerate": 48000
        }
    ],
    "volume": 64,
    "volume-max": 130,
    "playlist": [         # <-- All files in the current playlist
        {
            "filename": "Videos/big_buck_bunny_1080p_stereo.ogg",
            "current": true,
            "playing": true
        }
    ]
}

Thanks

Thanks to open-dynaMIX and makedin for their work on this.

Differences to mpv-web-ui

• More media controls
• Playlist controls
• Some styles and font-awesome
• ipv6 support
• Option to set the port being used (defaults to 8888)
• Using the Media Session API

Warning

These are my first steps with lua, so I'm just happy it works.
