Ncmcpp是一个mpd客户端，它提供了很多方便的操作

MPD是一个服务器-客户端架构的音频播放器。功能包括音频播放, 播放列表管理和音乐库维护，所有功能占用的资源都很少。

--取自 wiki.archlinux.org

很好用的一个命令行下的音乐播放器，然而在配置的过程中出现了一些小问题

安装

yourt -S mpd ncmpcpp

配置服务端 MPD

安装mpd后，给每个用户做配置

复制/usr/share/doc/mpd/mpd.conf.example到～/.config/mpd/mpd.conf

然后对其配置，每个配置的作用详见https://wiki.archlinux.org/index.php/Music_Player_Daemon

mkdir ～/.config/mpd

cp /usr/share/doc/mpd/mpd.conf.example～/.config/mpd/mpd.conf

nvim ～/.config/mpd/mpd.conf

# mpd.conf

music_directory		"/your/Music/path"

playlist_directory		"~/.mpd/playlists"

db_file			"~/.mpd/database"

log_file			"~/.mpd/log"

pid_file			"~/.mpd/pid"

state_file			"~/.mpd/state"

sticker_file			"~/.mpd/sticker.sql"

bind_to_address		"localhost"

port				"6600"

audio_output {

    type                    "fifo"

    name                    "my_fifo"

    path                    "/tmp/mpd.fifo"

    format                  "44100:16:2"

}

audio_output {

	type		"alsa"

	name		"ALSA"

	device		"hw:0,0"	# optional

	mixer_type       "hardware"	# optional

	mixer_device	"default"	# optional

	mixer_control	"Master"		# optional

	mixer_index	"0"		# optional

}

...

配置服务端Ncmpcpp

首先运行一下ncmpcpp，生成一下配置文件；或者直接复制样例配置

这里以mpd开头的项与mpd的配置相同

cp /usr/share/doc/ncmpcpp/config ~/.ncmpcpp/config

nvim ~/.ncmpcpp/config

# ~/.ncmpcpp/config

mpd_host = "localhost"

mpd_port = "6600"

mpd_music_dir = "/your/Music/path"

visualizer_fifo_path = /tmp/mpd.fifo

visualizer_output_name = Visualizer feed

visualizer_in_stereo = yes

visualizer_sync_interval = 30

visualizer_type = wave

visualizer_look = ●▮

visualizer_color = blue, cyan, green, yellow, magenta, red

...

Ncmpcpp使用方法

详见Basic Usage https://wiki.archlinux.org/index.php/Ncmpcpp

按键绑定详见 /usr/share/doc/ncmpcpp/bindings

附加一下 用Delete删除playlist的歌曲

配置出现的问题

• Ncmpcpp不能调节音量，左下角显示"MPD: no mixer"

查看~/.mpd/log发现是control的问题

exception: Failed to open mixer for 'My ALSA Device': no such mixer control: PCM

检查mpd.conf的audio_output设置

若使用alsa，用amixer查询control

$ amixer

Simple mixer control 'Master',0

  Capabilities: pvolume pswitch pswitch-joined

  Playback channels: Front Left - Front Right

  Limits: Playback 0 - 65536

  Mono:

  Front Left: Playback 8419 [13%] [on]

  Front Right: Playback 8419 [13%] [on]

Simple mixer control 'Capture',0

  Capabilities: cvolume cswitch cswitch-joined

  Capture channels: Front Left - Front Right

  Limits: Capture 0 - 65536

  Front Left: Capture 10093 [15%] [on]

  Front Right: Capture 10093 [15%] [on]

# 对应的mpd.conf audio_output配置

audio_output {

	type		"alsa"

	name		"ALSA"

	device		"hw:0,0"	# optional

	mixer_type       "hardware"	# optional

	mixer_device	"default"	# optional

	mixer_control	"Master"		# optional 注意此处

	mixer_index	"0"		# optional

}

• Ncmpcpp配置无误，但就是没有音乐
  
  进入ncmpcpp，按下2或4，选择文件（文件夹），按下a，添加到playlist即可
