This patch makes the shout checks use MPD_AUTO_PKG() instead of
manually invoking PKG_CHECK_MODULES(). It sets the default value to
"auto" instead of "no".
$enable_encoder specifies whether one or more encoder plugins are
enabled. This simplifies several checks, and allows easier
integration of more encoder plugins.
This patch adds a small autoconf M4 library which deals with
auto-detected features. The default for those features is "auto",
which is like the old default: if the library is present on the
system, enable the feature, disable otherwise. If the user explicitly
enables that feature (--enable-alsa), and the library is not present,
configure must fail, because it cannot fulfill the request.
We're using GLib macros which were introduced in GLib 2.6, like
G_GNUC_MALLOC. Let's just drop support for GLib versions older than
2.6 instead of adding more complicated compatibility hacks.
Let's get rid of the "shout" plugin, and the awfully complicated
icecast daemon setup! MPD can do better if it's doing the HTTP server
stuff on its own. This new plugin has several advantages:
- easier to set up - only one daemon, no password settings, no mount
settings
- MPD controls the encoder and thus already knows the packet
boundaries - icecast has to parse them
- MPD doesn't bother to encode data while nobody is listening
This implementation is very experimental (no header parsing, ignores
request URI, no icy-metadata, ...). It should be able to suport
several encoders in parallel in the future (with different bit rates,
different codec, ...), to make MPD the perfect streaming server. Once
MPD gets multi-player support, we can even mount several different
radio stations on one server.
If the header valgrind/memcheck.h is available, add
VALGRIND_MAKE_MEM_NOACCESS() and VALGRIND_MAKE_MEM_UNDEFINED()
support, which enables nice warnings in the valgrind memory checker.
The lastfm input plugin enables MPD to play lastfm:// URLs. This
plugin is not complete yet: it plays only the first song in the
last.fm playlist, and the playlist parser isn't even implemented
properly.
Recursive Makefiles are inefficient and error prone (no proper way to
declare dependencies). Since there's no disadvantage in having one
single Makefile, let's do it.
The configure.ac script does not care about the host architecture, it
only cares about the OS. Use ${host_os} instead of ${host} to
simplify the matching expressions.
Use faacDecInit2() instead of AudioSpecificConfig() to detect the AAC
track in the MP4 file. This has a great advantage: it initializes the
libfaad decoder, which the caller would normally do anyway - but now
we can go without the AudioSpecificConfig() call. When decoder==NULL
(called from mp4_tag_dup()), fall back to a mp4ff_get_track_type()==1
check, like other audio players do.
Currently, only the sidplay decoder plugin requires C++, and in all
other cases, MPD could build well without a C++ compiler.
Unfortunately, autoconf/automake are confused when we have a
conditional AC_PROG_CXX check. We could add lots of workarounds for
individual problems, but let's just always require a C++ compiler, and
forget about this autotools limitation.
There are a few problems left in this plugin:
- fluidsynth decodes in real time, while MPD prefers to buffer as
quickly as possible; as a workaround, this plugin uses a timer
object to synchronize with real-time playback
- I don't know yet how fluidsynth tells me when the song has ended
- the "soundfont" configuration setting is not yet documented, and it
will likely change soon (in favor of a per-decoder configuration
block)
When the sidplay plugin is disabled, "./configure" does not look for
the C++ compiler. This creates an odd situation: automake requires
the am__fastdepCXX conditional, although configure did not generate
it. Work around this autotools limitation by manually disabling
am__fastdepCXX.
Don't define HAVE_FFMPEG if the ffmpeg libraries were found via
pkg-config, but ffmpeg support was disabled because
avcodec_decode_audio2() is not available.
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.
MPD will (optionall) use sqlite databases in the future. Add a
configure option to enable that. There is no code yet to really use
sqlite, so the practical use of this patch is limited.
libid3tag comes without a pkg-config file, and it is usually added by
distribution packages. For those without .pc file, attempt to
auto-detect the library with AC_CHECK_LIB.
This is a rather huge patch, which unfortunately cannot be splitted.
Instead of using our custom ioops.h library, convert everything to use
the GLib main loop.
Don't split configure options and their implementation. Check for the
backend library before the AM_CONDITIONAL, otherwise Makefile.am will
compile the plugin although the library may not be available.
When updating from a version before libcurl was used for streaming
support, this is confusing - streaming will work with the old version
(e.g. 0.13.2) but will give "no such file" errors with the new due to
the missing dependency. However, the missing dependency will not be
obvious when running the configure script.
neaacdec.h declares all arguments as "unsigned long", but internally
expects uint32_t pointers. This triggers gcc warnings on 64 bit
architectures. To avoid that, make configure.ac detect whether we're
using Debian's corrected headers or the original libfaad headers. In
any case, pass a pointer to an uint32_t, conditionally casted to
"unsigned long*".
MPD used to have a copy of the mp4ff library. Since that has been
removed, AAC suport was disabled when there was no libmp4ff. Separate
the libmp4ff test, and enable AAC support no matter if libmp4ff is
available.
MPD's HTTP client code has always been broken, no matter how effort
was put into fixing it. Replace it with libcurl, which is known to be
quite stable. This adds a fat library dependency, but only for people
who need streaming.
Several clients refuse to accept the protocol version "0.14~git",
because they think it is malformed. This is clearly a client bug, but
we cannot wait for all clients to fix this bug right now. For now,
change the version back to "0.14.0".
For testers, it should be clear that they're not using version 0.14.0
final, but an inofficial intermediate version from the git repository.
The protocol version is set to the same string, since the protocol is
subject to change during MPD development.
MPD shouldn't integrate sources of other libraries. Since libmp4ff is
part of libfaad, we should remove the old copy from src/mp4ff and link
with the current version from libfaad instead.
Since ffmpeg svn r12865, you have to include libavcodec/avcodec.h
instead of avcodec.h. This cannot be checked at compile time, instead
we have to add a check to configure.ac. Viliam's original ffmpeg
plugin was based on the newer ffmpeg library, while my Debian
installation had the older version. My attempt to correct his include
statements wasn't correct after all.
With heavy use of conditionals, I broke Makefile.am for the ancient
automake version 1.6. Instead of supporting this automake version
forever, I'm removing support for it now. Since automake isn't
required on the build machine, nobody should have a serious problem
with that.
