[Risolto] Demone MPD come si attiva?

Un “buona sera” a tutti ! :slight_smile:

mi chidevo , dopo aver scaricato e installato una screenlets per MPD; di come bisogna attivare MPD “music player daemon?”

da yum ho installato:

Installazione:
mpd x86_64 0.15-1.fc11 rpmfusion-free-updates 188 k
Installazioni per dipendenze:
zziplib x86_64 0.13.49-7.fc11 fedora 72 k

Transaction Summary

tuttavia non riesco ad ascoltare la musica… comincio a pensare che ci sia qualcosa da configurare… o no?

saluti

provando ad avviarlo da terminale:

An example configuration file for MPD

See the mpd.conf man page for a more detailed description of each parameter.

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/mpd.db”

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/lib/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 “~/.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/mpdstate”

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

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 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.

For network

#bind_to_address “any”

And for Unix Socket

#bind_to_address “~/.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 from http://www.willwap.co.uk/Programs/vbrfix.php), at which

point gapless MP3 playback can be enabled.

#gapless_mp3_playback “yes”

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. Optionally, ‘comment’ can be added to this

list.

#metadata_to_use “artist,album,title,track,name,genre,date,composer,performer,disc”

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

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”

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

Input

input {
plugin “curl”

proxy “proxy.isp.com:8080

proxy_user “user”

proxy_password “password”

}

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

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.

See http://mpd.wikia.com/wiki/Configuration#Audio_Outputs for examples of

other audio outputs.

An example of an ALSA output:

#audio_output {

type “alsa”

name “My ALSA Device”

device “hw:0,0” # optional

format “44100:16:2” # optional

mixer_device “default” # optional

mixer_control “PCM” # optional

mixer_index “0” # optional

#}

An example of an OSS output:

#audio_output {

type “oss”

name “My OSS Device”

device “/dev/dsp” # optional

format “44100:16:2” # optional

mixer_device “/dev/mixer” # optional

mixer_control “PCM” # optional

#}

An example of a shout output (for streaming to Icecast):

#audio_output {

type “shout”

encoding “ogg” # optional

name “My Shout Stream”

host “localhost”

port “8000”

mount “/mpd.ogg”

password “hackme”

quality “5.0”

bitrate “128”

format “44100:16:1”

protocol “icecast2” # optional

user “source” # optional

description “My Stream Description” # optional

genre “jazz” # optional

public “no” # optional

timeout “2” # optional

#}

An example of a httpd output (built-in HTTP streaming server):

#audio_output {

type “httpd”

name “My HTTP Stream”

encoder “vorbis” # optional, vorbis or lame

port “8000”

quality “5.0” # do not define if bitrate is defined

bitrate “128” # do not define if quality is defined

format “44100:16:1”

#}

An example of a pulseaudio output (streaming to a remote pulseaudio server)

#audio_output {

type “pulse”

name “My Pulse Output”

server “remote_server” # optional

sink “remote_server_sink” # optional

#}

Example “pipe” output:

#audio_output {

type “pipe”

name “my pipe”

command “aplay -f cd 2>/dev/null”

Or if you’re want to use AudioCompress

command “AudioCompress -m | aplay -f cd 2>/dev/null”

Or to send raw PCM stream through PCM:

command “nc example.org 8765”

format “44100:16:2”

#}

An example of a null output (for no audio output):

#audio_output {

type “null”

name “My Null Output”

#}

This setting will change all decoded audio to be converted to the specified

format before being passed to the audio outputs. By default, this setting is

disabled.

#audio_output_format “44100:16:2”

If MPD has been compiled with libsamplerate support, this setting specifies

the sample rate converter to use. Possible values can be found in the

mpd.conf man page or the libsamplerate documentation. By default, this is

setting is disabled.

#samplerate_converter “Fastest Sinc Interpolator”

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

Volume control mixer

These are the global volume control settings. By default, this setting will

be detected to the available audio output device, with preference going to

hardware mixing. Hardware and software mixers for individual audio_output

sections cannot yet be mixed.

An example for controlling an ALSA, OSS or Pulseaudio mixer; If this

setting is used other sound applications will be affected by the volume

being controlled by MPD.

#mixer_type “hardware”

An example for controlling all mixers through software. This will control

all controls, even if the mixer is not supported by the device and will not

affect any other sound producing applications.

#mixer_type “software”

This example will not allow MPD to touch the mixer at all and will disable

all volume controls.

#mixer_type “disabled”

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

Normalization automatic volume adjustments

This setting specifies the type of ReplayGain to use. This setting can have

the argument “album” or “track”. See http://www.replaygain.org for more

details. This setting is disabled 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 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”

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

MPD Internal Buffering

This setting adjusts the size of internal decoded audio buffering. Changing

this may have undesired effects. Don’t change this if you don’t know what you

are doing.

#audio_buffer_size “2048”

This setting controls the percentage of the buffer which is filled before

beginning to play. Increasing this reduces the chance of audio file skipping,

at the cost of increased time prior to audio playback.

#buffer_before_play “10%”

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

Resource Limitations

These settings are various limitations to prevent MPD from using too many

resources. Generally, these settings should be minimized to prevent security

risks, depending on the operating resources.

#connection_timeout “60”
#max_connections “10”
#max_playlist_length “16384”
#max_command_list_size “2048”
#max_output_buffer_size “8192”

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

Character Encoding

If file or directory names do not display correctly for your locale then you

may need to modify this setting. After modification of this setting mpd

–create-db must be run to change the database.

#filesystem_charset “UTF-8”

This setting controls the encoding that ID3v1 tags should be converted from.

#id3v1_encoding “ISO-8859-1”

[root@Vaio turano]#

non è configurato

quello che temevo :slight_smile:
quindi devo andare in /etc/mpd.conf e settare i vari parametri?

dai una occhiata http://wiki.archlinux.org/index.php/Music_Player_Daemon a partire dalla configurazione.

ok non è stato facilino comunque ecco cosa ho combinato:

music_directory “/home/turano/Musica”
playlist_directory “/home/turano/Musica”
db_file “/var/lib/mpd/mpd.db”
log_file “/var/lib/mpd/mpd.log”
state_file “/var/lib/mpd/mpdstate”
user “mpd”
port “6600”

mixer_control “PCM” # optional
mixer_index “0” # optional
}
mixer_type “alsa”

utttavia da root: mpd
mi dice che non riesce ad accedere a home/musica permission deined
??? cioè

permessi della /home/turano/Musica ?

# ll /home/turano/

inoltre il demone con quali permessi “gira” ?

# ps -Al|grep mpd

posta l’output.

dai permessi di lettura e scrittura alla directory Musica anche al gruppo, poi aggiungi al gruppo del tuo utente anche l’utente mpd.

fatto! ma nulla sempre lo stesso problema.

forse è la configurazione che fà acqua da tutte le parti :frowning:
devo smanettarci sù un po ma gari riesco a concluderci qualcosa non è certo semplice

ok tutto perfetto mi è bastato spostare tutti i file in home e risolto il caso:
music_directory “/home/turano/Musica”
playlist_directory “/home/turano/.mpd/playlists”
db_file “/home/turano/.mpd/mpd.db”
log_file “/home/turano/.mpd/mpd.log”
error_file “/home/turano/.mpd/mpd.error”
pid_file “/home/turano/.mpd/mpd.pid”
state_file “/home/turano/.mpd/mpdstate”
user “turano”
port “6600”
default_permissions “read,add,control,admin”
audio_output {
type “alsa”
name “ALSA”
device “hw:0,0” # optional
format “44100:16:2” # optional
mixer_device “default” # optional
mixer_control “PCM” # optional
mixer_index “0” # optional
}
mixer_type “alsa”

bravo.

è stato necessario settare i permessi sulla directory ?

si! Creata la directory /home/turano/.mpd
è stato necessaro confermare al gruppo “turano” i permessi lettura scrittura files su detta cartella :smiley:

be si. bosigna creare a manina e inserire tutti i file presenti nel files.conf

bene così
