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.
