Configuring Music Player Daemon (MPD) and Clients on macOS

Music Player Daemon

Setup MPD

安装后，可以通过如下命令创建配置目录并启动/关闭mpd服务。这里个人按照 XDG Base Directory Specification，将mpd配置文件放在 ~/.config/mpd/ 目录下

MPD is an audio player that has a server-client architecture. MPD plays audio files, organizes playlists and maintains a music database, all while using very few resources. In order to interface with it, a separate client is needed.

# The default config dir is ~/.mpd# I prefer use $XDG_CONFIG_PATH to store mpd config;mkdir ~/.config/mpdmkdir ~/.config/mpd/playlists# Start/Kill Mpdmpd ~/.config/mpd/mpd.confpkill mpd

MPD配置[1]Check mpd.conf — Music Player Daemon 0.25~git documentation for detailed documentation.里可以指定多个 audio_output，添加 fifo 输出可以配合 cava 做音乐可视化

~/.config/mpd/mpd.conf
music_directory    "~/Music/CloudMusic"bind_to_address    "127.0.0.1"port               "6600"audio_output { type "osx" name "CoreAudio" mixer_type "software"}audio_output { type "fifo" name "my_fifo" path "/tmp/mpd.fifo" format "44100:16:2" auto_resample "no" use_mmap "yes"}

MPC

MPC[2]Music Player Client， mpc - Music Player Daemon提供了一个minimalist CLI to MPD，可以够满足基本的播放需求；例如使用如下命令切换歌曲、查看当前播放、根据 ID3Tags[3]ID3 - 维基百科，自由的百科全书 搜索歌曲等

MPC Examples
# 切换到下一首$ mpc nextRadiohead - Pyramid Song[playing] #7/50   0:00/4:49 (0%)volume: 96%   repeat: off   random: off   single: off   consume: off# 查看当前播放的音乐$ mpc currentRadiohead - Pyramid Song# 使用ID3Tags查询音乐文件$ mpc search artist radiohead摇滚/Radiohead - Pyramid Song.mp3摇滚/Radiohead - How Can You Be Sure？.mp3...摇滚/Radiohead - Fake Plastic Trees.mp3摇滚/Radiohead - Black Star.mp3

可以利用mpc提供的接口实现一些脚本，或集成到SketchyBar，i3 status等状态栏中

mpd启动后，播放队列默认为空，可以执行下述命令将所有音乐文件添加到队列中

mpc clearmpc listall | mpc add

RMPC

如果想要一个更丰富的TUI体验，可以下载RMPC，它是用Rust编写的MPD客户端，功能丰富且高度可配置

Rmpc Features

  • Album cover art display if your terminal supports either of Kitty, Sixel, Iterm2 protocols, or via ueberzuggpp
  • Cava integration for music visualisation
  • Support for synchronized lyrics
  • Ability to play music from YouTube
  • Configurable (T) UI
    • Configure what information (if any!) is displayed in the header
    • Configure what columns are displayed on the queue pane
    • Completely customize what tabs are rendered and mix and match their content
    • Create any color theme you want
    • Every keybind can be changed, vim-like by default
  • Ranger/LF-like three-column browser through your music library
  • Basic playlist management
  • Support scripting through basic CLI mode and script hooks
  • Remote control - Send commands to running rmpc instances (useful for window manager integration).

个人配置后的RMPC界面预览如下：

这里特别说一下RMPC的歌词和可视化功能

根据 Lyrics fetching from the song file · Issue #287，RMPC目前还不支持从mp3/flac文件中读取嵌入的歌词标签，要想显示歌词需要额外准备 lrc 文件。

现在工具很成熟，可以使用音乐标签Android版 等软件轻易完成批处理

可以为rmpc添加可视化功能，步骤如下：

  1. 安装cava，在mpd配置中添加fifo输出（见上文mpd配置部分）
  2. 在rmpc配置中启用cava功能
  3. 在Queue Tab中启用cava显示（也可以选择在其他tab显示）
  4. cava主题配置

rmpc使用RON (Rusty Object Notation) 作为配置语言，上手需要一定的学习成本，这里就不展开介绍个人的配置细节了，可以参考我的配置仓库[4]Visit GitHub for my Mpd Configs & Rmpc Configs。

Now Playing for MPD on macOS

对于MacOS来说，mpd不是一个now-playable app[5]Becoming a now playable app | Apple Developer Documentation，即在播放音乐时，MacOS的now-playing组件无法显示当前播放的音乐信息，此外也无法使用多媒体按键进行控制。

解决方案：

-. 下载 mpd-now-playable

brew install pipxpipx install mpd-now-playable

-. 安装好后，运行 mpd-now-playable 即可，可执行文件路径位于 ~/.local/bin
