From caa4d28f044d70012cd113f324e6500c0b57d491 Mon Sep 17 00:00:00 2001 From: Max Kellermann Date: Thu, 29 Jan 2009 21:42:10 +0100 Subject: [PATCH] added support for the MMS protocol This patch implements the MMS protocol, by using libmms. It is quite experimental: it does not support seeking yet, and it is currently using synchronous I/O, which causes MPD to hang while waiting for the server. --- INSTALL | 3 ++ NEWS | 1 + configure.ac | 18 +++++++ src/Makefile.am | 7 +++ src/input_mms.c | 120 +++++++++++++++++++++++++++++++++++++++++++++ src/input_mms.h | 24 +++++++++ src/input_stream.c | 7 +++ src/ls.c | 6 +++ 8 files changed, 186 insertions(+) create mode 100644 src/input_mms.c create mode 100644 src/input_mms.h diff --git a/INSTALL b/INSTALL index 0847805f0..87d6d5b7f 100644 --- a/INSTALL +++ b/INSTALL @@ -108,6 +108,9 @@ For advanced samplerate conversions. libcurl - http://curl.haxx.se/ For playing HTTP streams. +libmms - https://launchpad.net/libmms +For playing MMS streams. + pkg-config ---------- diff --git a/NEWS b/NEWS index 0caa90e96..88d52f09d 100644 --- a/NEWS +++ b/NEWS @@ -1,6 +1,7 @@ ver 0.15 - (200?/??/??) * input: - parse Icy-Metadata + - added support for the MMS protocol * tags: - support the "album artist" tag - support MusicBrainz tags diff --git a/configure.ac b/configure.ac index ff4c1457c..0461b839c 100644 --- a/configure.ac +++ b/configure.ac @@ -247,6 +247,18 @@ if test x$enable_curl = xyes; then fi AM_CONDITIONAL(HAVE_CURL, test x$enable_curl = xyes) +AC_ARG_ENABLE(mms, + AS_HELP_STRING([--enable-mms], + [enable the MMS protocol with libmms (default: disable)]),, + [enable_mms=yes]) + +if test x$enable_mms = xyes; then + PKG_CHECK_MODULES(MMS, [libmms], + AC_DEFINE(ENABLE_MMS, 1, [Define when libmms is used for the MMS protocol]), + AC_MSG_ERROR([libmms not found])) +fi +AM_CONDITIONAL(ENABLE_MMS, test x$enable_mms = xyes) + dnl dnl archive plugins @@ -1318,6 +1330,12 @@ else echo " HTTP streaming (libcurl) ......disabled" fi +if test x$enable_mms != xno; then + echo " MMS streaming (libmms) ........enabled" +else + echo " MMS streaming (libmms) ........disabled" +fi + echo "" echo "##########################################" echo "" diff --git a/src/Makefile.am b/src/Makefile.am index 7cbd3154c..de9c99f1f 100644 --- a/src/Makefile.am +++ b/src/Makefile.am @@ -4,6 +4,7 @@ mpd_CFLAGS = $(MPD_CFLAGS) mpd_CPPFLAGS = \ $(SQLITE_CFLAGS) \ $(CURL_CFLAGS) \ + $(MMS_CFLAGS) \ $(AO_CFLAGS) $(ALSA_CFLAGS) \ $(SHOUT_CFLAGS) \ $(OGGVORBIS_CFLAGS) $(VORBISENC_CFLAGS) \ @@ -17,6 +18,7 @@ mpd_CPPFLAGS = \ mpd_LDADD = $(MPD_LIBS) \ $(SQLITE_LIBS) \ $(CURL_LIBS) \ + $(MMS_LIBS) \ $(AO_LIBS) $(ALSA_LIBS) \ $(SHOUT_LIBS) \ $(OGGVORBIS_LIBS) $(VORBISENC_LIBS) $(FLAC_LIBS) \ @@ -64,6 +66,7 @@ mpd_headers = \ input_stream.h \ input_file.h \ input_curl.h \ + input_mms.h \ icy_metadata.h \ client.h \ listen.h \ @@ -314,6 +317,10 @@ if HAVE_CURL mpd_SOURCES += input_curl.c icy_metadata.c endif +if ENABLE_MMS +mpd_SOURCES += input_mms.c +endif + if HAVE_ALSA mpd_SOURCES += output/alsa_plugin.c diff --git a/src/input_mms.c b/src/input_mms.c new file mode 100644 index 000000000..f9b2edeaa --- /dev/null +++ b/src/input_mms.c @@ -0,0 +1,120 @@ +/* + * 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.
