mpd
For Linux platform (e.g. Raspbian) the following command installs 'mpd' player in folder /usr/bin
sudo apt-get install mpd
For debugging and updating 'mpd' dictionary it's recommended to install 'mpc' as well. This is a command line client for 'mpd'. To install 'mpc' run this command:
sudo apt-get install mpc
Set 'mpd' mixer type to 'software' to control volume from Peppy UI. For that uncomment the line with mixer_type in file /etc/mpd.conf:
audio_output {
type "alsa"
name "My ALSA Device"
# device "hw:0,0" # optional
mixer_type "software" # optional
# mixer_device "default" # optional
# mixer_control "PCM" # optional
# mixer_index "0" # optional
After installing 'mpd' it's automatically configured as a service and it will start every time the Raspberry Pi starts. In order to have full control on 'mpd' player it's better to stop 'mpd' service and disable it from starting upon system startup
sudo service mpd stop
sudo update-rc.d mpd disable
The following example shows parameters which should be defined in audio section of the players.txt file in order to use mpd:
[audio]
player.name = mpd
music.folder.linux = /music
music.folder.windows = C:\music
The following parameters defined in players.txt file will be used to run mpd player on Linux platform:
[mpd.linux]
server.folder = /usr/bin
server.command = mpd
client.name = mpdsocket
The following parameters defined in players.txt file will be used to run mpd player on Windows platform:
[mpd.windows]
server.folder = C:\mpd-0.17.4-win32\bin
server.command = mpd mpd.conf
client.name = mpdsocket
To use file playback functionality with 'mpd' the property music.folder in players.txt should be set to the same value as property music_directory in mpd.conf file.
Peppy player doesn't update mpd's dictionary. Therefore don't forget to run command 'mpc update' whenever new folder/file was added to the music directory.
The communication with 'mpd' player includes commands which UI sends to the player and notifications which player sends back to UI. The following diagram shows how this communication was implemented:
The following table lists the functionality available from 'mpd' on different platforms. The lack of particular functionality doesn't mean that player doesn't provide it. That just means that it's currently not available in Peppy player and probably will be supported in the future.
