From 3679d5bd7ac3a64d342b204c821dc6ccb891ad67 Mon Sep 17 00:00:00 2001 From: Max Kellermann Date: Wed, 16 Dec 2009 20:04:36 +0100 Subject: playlist: added CUE playlist plugin This plugin is the groundwork for MPD's future generic CUE sheet support. That's not complete yet, e.g. there is no way for a playlist plugin to address an arbitrary position within a music file. --- src/playlist/cue_playlist_plugin.c | 137 +++++++++++++++++++++++++++++++++++++ src/playlist/cue_playlist_plugin.h | 25 +++++++ 2 files changed, 162 insertions(+) create mode 100644 src/playlist/cue_playlist_plugin.c create mode 100644 src/playlist/cue_playlist_plugin.h (limited to 'src/playlist') diff --git a/src/playlist/cue_playlist_plugin.c b/src/playlist/cue_playlist_plugin.c new file mode 100644 index 00000000..8db0018c --- /dev/null +++ b/src/playlist/cue_playlist_plugin.c @@ -0,0 +1,137 @@ +/* + * Copyright (C) 2003-2009 The Music Player Daemon Project + * http://www.musicpd.org + * + * This program is free software; you can redistribute it and/or modify + * it under the terms of the GNU General Public License as published by + * the Free Software Foundation; either version 2 of the License, or + * (at your option) any later version. + * + * This program is distributed in the hope that it will be useful, + * but WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
