如何使用 mpd 在 icecast 中创建具有不同播放列表的多个挂载点?

How to create multiple mount points with different playlists in icecast with mpd?

我已经在服务器上安装了带有YMPD客户端的icecast和MPD。

目前是运行单机。我想在不同的安装方式上流式传输音频,例如:/stream.ogg、/mp3、/audio 以及不同的播放列表。

下面是我的配置文件:

1. mpd.conf:

# An example configuration file for MPD.
# Read the user manual for documentation: http://www.musicpd.org/doc/user/
# or /usr/share/doc/mpd/user-manual.html


# Files and directories #######################################################
#
# This setting controls the top directory which MPD will search to discover the
# available audio files and add them to the daemon's online database. This 
# setting defaults to the XDG directory, otherwise the music directory will be
# be disabled and audio files will only be accepted over ipc socket (using
# file:// protocol) or streaming files over an accepted protocol.
#
music_directory     "/var/lib/mpd/music"
#
# This setting sets the MPD internal playlist directory. The purpose of this
# directory is storage for playlists created by MPD. The server will use 
# playlist files not created by the server but only if they are in the MPD
# format. This setting defaults to playlist saving being disabled.
#
playlist_directory      "/var/lib/mpd/playlists"
#
# This setting sets the location of the MPD database. This file is used to
# load the database at server start up and store the database while the 
# server is not up. This setting defaults to disabled which will allow
# MPD to accept files over ipc socket (using file:// protocol) or streaming
# files over an accepted protocol.
#
db_file         "/var/lib/mpd/tag_cache"
# 
# These settings are the locations for the daemon log files for the daemon.
# These logs are great for troubleshooting, depending on your log_level
# settings.
#
# The special value "syslog" makes MPD use the local syslog daemon. This
# setting defaults to logging to syslog, otherwise logging is disabled.
#
log_file            "/var/log/mpd/mpd.log"
#
# This setting sets the location of the file which stores the process ID
# for use of mpd --kill and some init scripts. This setting is disabled by
# default and the pid file will not be stored.
#
pid_file            "/run/mpd/pid"
#
# This setting sets the location of the file which contains information about
# most variables to get MPD back into the same general shape it was in before
# it was brought down. This setting is disabled by default and the server 
# state will be reset on server start up.
#
state_file          "/var/lib/mpd/state"
#
# The location of the sticker database.  This is a database which
# manages dynamic information attached to songs.
#
sticker_file                   "/var/lib/mpd/sticker.sql"
#
###############################################################################


# General music daemon options ################################################
#
# This setting specifies the user that MPD will run as. MPD should never run as
# root and you may use this setting to make MPD change its user ID after
# initialization. This setting is disabled by default and MPD is run as the
# current user.
#
#user               "mpd"
#
# This setting specifies the group that MPD will run as. If not specified
# primary group of user specified with "user" setting will be used (if set).
# This is useful if MPD needs to be a member of group such as "audio" to
# have permission to use sound card.
#
#group                          "nogroup"
#
# This setting sets the address for the daemon to listen on. Careful attention
# should be paid if this is assigned to anything other then the default, any.
# This setting can deny access to control of the daemon. Choose any if you want
# to have mpd listen on every address. Not effective if systemd socket
# activation is in use.
#
# For network
bind_to_address     "127.0.0.1"
#
# And for Unix Socket
#bind_to_address        "/run/mpd/socket"
#
# This setting is the TCP port that is desired for the daemon to get assigned
# to.
#
port                "6600"
#
# This setting controls the type of information which is logged. Available 
# setting arguments are "default", "secure" or "verbose". The "verbose" setting
# argument is recommended for troubleshooting, though can quickly stretch
# available resources on limited hardware storage.
#
#log_level          "default"
#
# If you have a problem with your MP3s ending abruptly it is recommended that 
# you set this argument to "no" to attempt to fix the problem. If this solves
# the problem, it is highly recommended to fix the MP3 files with vbrfix
# (available as vbrfix in the debian archive), at which
# point gapless MP3 playback can be enabled.
#
#gapless_mp3_playback           "yes"
#
# Setting "restore_paused" to "yes" puts MPD into pause mode instead
# of starting playback after startup.
#
#restore_paused "no"
#
# This setting enables MPD to create playlists in a format usable by other
# music players.
#
#save_absolute_paths_in_playlists   "no"
#
# This setting defines a list of tag types that will be extracted during the 
# audio file discovery process. The complete list of possible values can be
# found in the mpd.conf man page.
#metadata_to_use    "artist,album,title,track,name,genre,date,composer,performer,disc"
#
# This setting enables automatic update of MPD's database when files in 
# music_directory are changed.
#
#auto_update    "yes"
#
# Limit the depth of the directories being watched, 0 means only watch
# the music directory itself.  There is no limit by default.
#
#auto_update_depth "3"
#
###############################################################################


# Symbolic link behavior ######################################################
#
# If this setting is set to "yes", MPD will discover audio files by following 
# symbolic links outside of the configured music_directory.
#
#follow_outside_symlinks    "yes"
#
# If this setting is set to "yes", MPD will discover audio files by following
# symbolic links inside of the configured music_directory.
#
#follow_inside_symlinks     "yes"
#
###############################################################################


# Zeroconf / Avahi Service Discovery ##########################################
#
# If this setting is set to "yes", service information will be published with
# Zeroconf / Avahi.
#
#zeroconf_enabled       "yes"
#
# The argument to this setting will be the Zeroconf / Avahi unique name for
# this MPD server on the network.
#
#zeroconf_name          "Music Player"
#
###############################################################################


# Permissions #################################################################
#
# If this setting is set, MPD will require password authorization. The password
# can setting can be specified multiple times for different password profiles.
#
#password                        "password@read,add,control,admin"
#
# This setting specifies the permissions a user has who has not yet logged in. 
#
default_permissions             "read,add,control,admin"
#
###############################################################################


# Database #######################################################################

# Audio Output ################################################################
#
# MPD supports various audio output types, as well as playing through multiple 
# audio outputs at the same time, through multiple audio_output settings 
# blocks. Setting this block is optional, though the server will only attempt
# autodetection for one sound card.

###############################################################################


# Normalization automatic volume adjustments ##################################
#
# This setting specifies the type of ReplayGain to use. This setting can have
# the argument "off", "album", "track" or "auto". "auto" is a special mode that
# chooses between "track" and "album" depending on the current state of
# random playback. If random playback is enabled then "track" mode is used.
# See <http://www.replaygain.org> for more details about ReplayGain.
# This setting is off by default.
#
#replaygain         "album"
#
# This setting sets the pre-amp used for files that have ReplayGain tags. By
# default this setting is disabled.
#
#replaygain_preamp      "0"
#
# This setting sets the pre-amp used for files that do NOT have ReplayGain tags.
# By default this setting is disabled.
#
#replaygain_missing_preamp  "0"
#
# This setting enables or disables ReplayGain limiting.
# MPD calculates actual amplification based on the ReplayGain tags
# and replaygain_preamp / replaygain_missing_preamp setting.
# If replaygain_limit is enabled MPD will never amplify audio signal
# above its original level. If replaygain_limit is disabled such amplification
# might occur. By default this setting is enabled.
#
#replaygain_limit       "yes"
#
# This setting enables on-the-fly normalization volume adjustment. This will
# result in the volume of all playing audio to be adjusted so the output has 
# equal "loudness". This setting is disabled by default.
#
#volume_normalization       "no"
#
###############################################################################


# Character Encoding ##########################################################
#
# If file or directory names do not display correctly for your locale then you 
# may need to modify this setting.
#
filesystem_charset      "UTF-8"
#
# This setting controls the encoding that ID3v1 tags should be converted from.
#
id3v1_encoding          "UTF-8"
#
###############################################################################


# SIDPlay decoder #############################################################
#
# songlength_database:
#  Location of your songlengths file, as distributed with the HVSC.
#  The sidplay plugin checks this for matching MD5 fingerprints.
#  See http://www.c64.org/HVSC/DOCUMENTS/Songlengths.faq
#
# default_songlength:
#  This is the default playing time in seconds for songs not in the
#  songlength database, or in case you're not using a database.
#  A value of 0 means play indefinitely.
#
# filter:
#  Turns the SID filter emulation on or off.

如何加载不同的流媒体文件或不同的播放列表?

我在icecast上做了多次安装。为此,我在服务器上创建了多个 mpd 实例。

并在不同的端口上启动每个 mpd。配置文件中添加的端口。 例如:

mpd /etc/mpd.conf    # mpd's configuration file path for start mpd

之后我在新端口上启动了新的 YMPD 实例作为 mpd 的客户端。

例如:

./ympd --port 6600 --webport 8085  # 6600 is mpd's port and 8085 is ympd's port.

现在每个 mpd 都有不同的播放列表和不同的流式音频装载 url。

默认配置

在默认配置中,您有几行如下所示:

    <listen-socket>
        <port>8000</port>
        <bind-address>0.0.0.0</bind-address>
        <shoutcast-mount>/stream</shoutcast-mount>
    </listen-socket>

您还会看到一些注释掉的行,如下所示:

    <!-- Normal mounts -->
    <!--
    <mount type="normal">
        <mount-name>/example-complex.ogg</mount-name>
        ... 
    </mount>
    -->

多个坐骑

如果您有多个源客户端,您可以通过添加“正常”(非默认)装载来发布到多个流:

    <listen-socket>
        <port>8000</port>
        <bind-address>0.0.0.0</bind-address>
        <shoutcast-mount>/stream</shoutcast-mount>
    </listen-socket>

    <mount type="normal">
        <mount-name>/stream-128k</mount-name>
    </mount>
    <mount type="normal">
        <mount-name>/stream-64k</mount-name>
    </mount>

我相信 strict shoutcast 只支持每个绑定端口一个挂载——它没有“路径”。

但是,只要您有要发布给它们的源客户端,您可以拥有任意数量的 icecast 坐骑。

liquidsoap 可以轻松地一次发布多个比特率。
