Adding podcasts to MPD using castget

Debian, Linux, Raspberry Pi, , , , ,

In order to play mp3 files on my RasPi, I’ve installed the Music Player Daemon (MPD). Music playback can be controlled with Mozilla Firefox using the Minion plugin. By placing *.m3u files into MPDs’ playlists folder, as configured in /etc/mpd.conf, it is possible to listen to internet radio streams.

Unfortunately, subscription to podcasts is not directly supported by MPD. However there’s a way to automatically download podcasts to MPD’s mp3 directory using a program called castget. It’s not in the Wheezy repo. Thus, it must be compiled from source:

$ ./configure --prefix=/usr
$ make
$ make install

To build castget, make sure to have the glib2, libxml2, libcurl and id3lib development packages installed on your Pi. Castget is using a default ./castgetrc in /home/pi for configuration, but one can point it to a different location by using the –rcfile=/etc/castgetrc flag. The castget tarball provides a sample configuration file.

# Global settings.

id3contenttype=Podcast
spool=/media/usb/podcasts

# Per-channel settings.

playlist=/var/lib/mpd/playlists/Computer_u_Kommunikation.m3u

[dsc]
url=http://www.deutschlandradiokultur.de/podcast-reportage.948.de.podcast.xml
playlist=/var/lib/mpd/playlists/Deutschland_Reportage.m3u

All you need to do is to define a spool directory for downloading the podcasts, to enter the URLs of the podcast’s RSS feeds and to tell castget where to store the playlist.m3u files (must be the the same directory as defined in /etc/mpd.conf).

To automatically check and download new podcasts each 24 hours at 02:00 am, I placed a new line into my /etc/crontab

 0  2    * * *   root    /usr/bin/castget -r --rcfile=/etc/castgetrc

If the download was successful, new podcasts should appear in Minion’s playlists tab.

Music Player Daemon (MPD) Workaround for the Firefox Minion Plugin

Linux, Networking, Uncategorized, Wheezy, , ,

There are a lot of tutorials out there on how to install the music player daemon (MPD) on a Raspberry Pi. Therefore, I’ll not describe it here in detail. On a freshly installed Debian Wheezy it should work out-of-the-box. An “apt-get install mpd” and editing /etc/mpd.conf should do the trick.

However, if you wish to control MPD with your browser using the FireFox Minion Plugin, you’ll certainly face the problem that it’s configuration dialog for the server’s IP-address/ port number appears to be broken.

Whatever you enter into the dialog will be ignored, and Minion will stay disconnected. It’s a bug, not a feature!

In order to set the IP-address and port number you have to type about:config into Firefox’ address bar and search for the string extensions.mpm.server.

Then, double-click on the entry and enter the desired IP:Portnumber.

Furthermore, depending on where you store your audio files (I keep them on a USB stick), file permissions can be an issue, if MPD is unable to see your files. Make sure that the folder containing the audiofiles is readable for the desired users.
