Usage

For mpv>=v0.33.0 you can just clone/copy the whole repository into your mpv scripts directory.

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

Installing for mpv <v0.33.0

Copy webui.lua and the webui-page-folder into your mpv scripts directory, mpv will then run it automatically.

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

---

See dependencies for more information about the installation.

You can access the webui when visiting http://127.0.0.1:8080 or http://[::1]:8080 in your webbrowser.

By default, it listens on 0.0.0.0:8080 and [::0]:8080. As described below, this can be changed.

Options

Information about how to set options can be found here.

port (int)

Set the port to serve the webui (default: 8080). 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

osd_logging (bool)

Log to OSD (default: yes)

Example:

webui-osd_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"

static_dir

Configure the directory from which the static files should be served.

This is useful, if you want to use an alternative frontend.

The provided path may be absolute or relative.

Example:

webui-static_dir="/path/to/directory"

Content types are hardcoded into the server. If you miss something, please create an issue or - even better - a pull request.

htpasswd_path

See authentication below.

Example:

webui-htpasswd_path="/path/to/file"

Relative paths are searched relative to the program's current working directory, so stick to absolute paths all the time.

Shortcuts to your homedir like ~/ are not supported.

collections

In order to use the basic file-browser API at /api/collections, the absolute paths of to-be exposed directories need to be configured here (semicolon delimited). By default, responses from /api/collections remain empty.

Example:

webui-collections="/home/user/Music;/home/user/Videos"

Setting options

There are three ways to set an option for the webui. Please refer to the MPV documentation for more details about this, as this is no feature of the webui.

CLI

If you want to set webui-options from the CLI, you need to pass them to --script-opts or --script-opts-add respectively, like this: --script-opts-add=webui-osd_logging=no.

mpv config file

If you want to set webui-options in the main mpv config file, you need to write it like this: script-opts-add=webui-osd_logging=no.

Webui config file

Finally, if you want to webui-options in their dedicated config file, you can put them in a file /path/to/mpv/user/dir/script-opts/webui.conf (usually ~/.config/mpv/script-opts/webui.conf on Linux) like this: osd_logging=no.

Authentication

There is a very simple implementation of Basic Authentication.

It can be enabled by providing the htpasswd file via the htpasswd_path option. The file does not need to be named htpasswd.

The provided file needs to contain data in the following format:

user1:password1
user2:password2

Only plaintext .htpasswd entries are supported.

Dependencies

Linux

• luasocket

Windows

In this repository you can find a guide, build script and pre-built binaries.

Thanks to @57op for providing this!

macOS

Install luarocks:

brew install luarocks

Check lua version of your mpv instance.

mpv -v

...
--lua=51deb # <- this is your lua version
...

Proceed to install correct luasocket:

luarocks --lua-dir=/usr/local/opt/lua@5.1 install luasocket

Set correct path:

eval $(luarocks --lua-dir=/usr/local/opt/lua@5.1 path --bin)

Key bindings

There are some keybindings available:

Key	Function
SPACE	Play/Pause
ArrowRight	seek +10
ArrowLeft	seek -10
ArrowUp	seek +1min
ArrowDown	seek -1min
PageDown	seek +3
PageUp	seek -3
9	decrease volume
0	increase volume
f	toggle fullscreen
n	playlist next
p	playlist previous
j	cycle subtitles
v	toggle subtitle visibility
[	decrease playback speed
]	increase playback speed
{	decrease playback speed more
}	increase playback speed more
Backspace	reset playback speed
Escape	hide current overlay
?	toggle keyboard shortcuts

Media Session API

When using a browser that supports it, simple-mpv-webui uses the Media Session API to provide a notification with some metadata and controls:

In order to have the notification work properly you need to at least once trigger play from the webui.

Playing other audio while using the webui on Android

For the notification to work, the webui plays a silent audio file in a loop. This is necessary in order for Chrome on Android to create such notification (see). As soon as this silent mp3 is played, audio from other apps is paused automatically by Android. The only way to prevent this from happening is to disable the notifications, which is possible in the settings of the webui (client).
