MPD -> MP3 Shoutcast Streaming Patches Accepted

ericw — Wed, 22 Oct 2008 06:01:51 +0000

Just a note to those of you that have tried my MP3 streaming patches for MPD; the patches have been accepted and will be included in the next release of MPD (version 0.14.0). If you want to try out the development version of MPD, that includes these patches, you can now do so by cloning the master git branch at git://git.musicpd.org/master/mpd.git.

MPD FLAC md5sum Support

ericw — Thu, 04 Sep 2008 04:40:40 +0000

Here’s another little patch for MPD‘s git repos that allows FLAC files to return md5sum as if it were a bit of metadata, like artist, title, or album. A FLAC file’s md5sum is about the closest thing you can get to a unique identifier for that file. The md5sum is generated from the wav file that is encoded when the FLAC file is created, so even if you change the filename, or its tags (vorbis comments), the md5sum will remain the same. This code is how Mildred correlates songs playing in MPD with songs in its database.

You can find the patch here: http://kill-0.com/patches/0001-Adds-FLAC-md5sum.patch

After applying the patch, you’ll want to re-create your MPD database file. You can use the --create-db flag to do so, or just delete your old database file before restarting MPD.

MPD MP3 -> Shoutcast streaming (part 2) [UPDATED Sept 15]

ericw — Tue, 26 Aug 2008 00:19:57 +0000

Update: due to wide-spread changes in the MPD git repository, this patch no longer applies and builds correctly. You can still play with the shout MP3 plugin by cloning my shiny-new git repository at: http://git.musicpd.org/encoded/mpd.git See the comments section below for information about configuration changes. The plugin is currently on the roadmap for the 0.14.0 release, so keep your fingers crossed.

I’ve updated my patch so that it can be applied against the current MPD git repository. Hopefully it will be rolled into MPD for the 0.14.0 release. The patch has been improved to do better configuration-time checking for the lame library. I also found a bug where I wasn’t setting the bit rate properly if constant bit rate was requeted.

I’m hoping to roll this out to Mildred soon.

MPD MP3 -> Shoutcast streaming

ericw — Sun, 24 Aug 2008 01:21:13 +0000

MPD is a great little project that collects, organizes, and plays your music files for you. You can connect to MPD and listen to your music in a great number of ways. You can even stream your music out as your own radio station (Mildred makes use of this functionality).

I’ve always thought it odd that MPD would stream in Ogg, but not MP3. Don’t get me wrong, I’m a big fan of open standards and all, but MP3 is just so dominant, that I was surprised MP3 streaming hadn’t been implemented. Add to that the stupid inability of Apple’s iTunes to stream Ogg and well, it motivated me. I sat down and hacked together a MPD plugin that allows you to stream MP3 to your shoutcast server from MPD.

Source patches for the plugin are available here: http://kill-0.com/patches/shout_mp3.patch

It’s rough around the edges, but it does work. You can even play it in iTunes.

Enjoy!

Voyeur: Growl Notifications for MPD

Voyeur is a very small bit of ruby code that I’ve written to display updates to your MPD stream via Growl.

You can find it here: http://kill-0.com/voyeur/

You start and stop it as you would a daemon, ie $ ./voyeur start and ./voyeur stop. As an added bonus, you can send it a HUP signal, and it will immediately display the current track information or status. Here’s a screen shot:
