The array must never be modified, it's a constant lookup table.

Looks like the MVP audio output only supports 16 and 24 bit audio
samples.  If MPD generates any other sample formats, force it to use
16 bit.

When the channel count is greater than 2, fall back to stereo sound.

Return true/false instead of 0/-1.  Also check its return value in
mvp_output_open().

Pass a pointer to the audio_format struct instead of 3 separate
integers.

Don't pass the big_endian flag to mvp_set_pcm_params(), do a simple
"G_BYTE_ORDER==G_LITTLE_ENDIAN" instead.

Instead of manually calculating the number of elements in the
mvp_sample_rates array, use GLib's convenience macro G_N_ELEMENTS().

Renamed types, functions and variables.

Return true/false instead of 1/0.

Return true/false for success/failure instead of returning 0/-1.

Renamed types, functions and variables.

The MPD core guarantees that the audio_output object is always
consistent, and our timer!=NULL checks are superfluous.

Renamed functions and variables.

The MPD core guarantees that the audio_output object is always in a
consistent state: either open or closed.  When open, it will not call
the open() method again, and when closed, it will not call play().
Removed several checks and the NULL initialization.

The method is empty, and we can simply set the method pointer to NULL
instead.

audio_output_get_name() has been removed, which was the only function
left in output_api.h.  The output plugin doesn't need the audio_output
object at all, remove the parameter from the init() method.

Use config_get_block_string("name") instead of audio_output_get_name().

Added a command line program which runs an encoder plugin.

Added a command line program which runs a decoder plugin.

Moved generic compiler options to AM_CFLAGS.  MPD_CFLAGS/MPD_LIBS will
hopefully fade away one day, in favor of more fine-grained variables.

Renamed the old AM_CFLAGS to AM_CPPFLAGS, because it contained only
preprocessor options.  Append it to src_mpd_CPPFLAGS.  Removed
GLIB_LIBS from src_mpd_CPPFLAGS, because it is already part of
AM_LDFLAGS.

Added "make" variables for the sources and dependencies of each
subsystem (archive, input, output, decoder, encoder, mixer).

"ls" is a bad name for a library which parses URIs.  We'll move the
rest of the "ls" library later.

Fix a gcc warning.

Don't return an uninitialized bool variable.

Fix a gcc warning, initialize the "space" variable at the beginning of
mpd_jack_play().

Work around gcc warnings by casting the parameters to void.

Don't explicitly check is_ipv6_enabled(), just try calling
listen_add_port_ipv6(), but check its error code.

Some more code simplification.

For default bind_to_address settings, don't call
listen_add_config_param(NULL), use listen_add_port() directly.

Split code from the rather large function listen_add_config_param(),
part 3.

Split code from the rather large function listen_add_config_param(),
part 2.

Split code from the rather large function listen_add_config_param().

Don't return -1 on failure, and abort on fatal error - do proper error
reporting with GError, and return false on failure.

Renamed functions.

Removed superfluous commas.

After much research[1][2][3] this should be the majority of currently
supported file extensions and mime-types for the currently supported
ffmpeg formats. This list maybe incomplete, but it's more complete
than anything else out there that I've been able to find. This list
needs to be updated every now and again as the ffmpeg sources support
more formats.

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.
