The function simplifies wavpack_replaygain(), because it already
contains the float parser, and it works with a fixed buffer instead of
doing expensive heap allocations.
The assertion on dc.state in decoder_read() was too strict: when a
decoder tried to call decoder_read() from tag_dup(), the decoder state
was NONE. Allow this special case.
The flac plugin wasn't initialized properly when an OGG file was being
decoded. For some reason, flac_process_metadata() was explicitly not
called for OGG files. Since that seems to fix the issue, make it
always call flac_process_metadata().
Since decoder_list.c does not include the libflac headers, it cannot
know whether to add the oggflac plugin to the decoder list. Solve
this by always enabling the oggflac sub-plugin, even with older
libflac versions. When the libflac API cannot support oggflac,
disable the plugin at runtime by returning "false" from its init()
method.
The "oggflac" plugin was enabled only if HAVE_FLAC_COMMON was
defined. HAVE_FLAC_COMMON however is only an automake variable, and
is never available in decoder_list.c. Make decoder_list.c depend on
HAVE_FLAC||HAVE_OGGFLAC instead.
The player did not care about the exact error value, it only checked
whether an error has occured. This could fit well into
decoder_control.state - introduce a new state "DECODE_STATE_ERROR".
At this moment the wavpack lib doesn't use the return value of the
push_back function, which has an equivalent meaning of the return
value of ungetc(). This is a lucky situation, because so far it
simply returned with 1 as a hard coded value. From now on the
function will return EOF on error. (This function makes exactly one
byte pushable back.)
There are some functions in the wavpack-mpd input streams wrapper
which had too commonly used names (especially can_seek). I prefixed
these with "wavpack_input_".
The listen.c module breaks the build because the variable name used
("sun") for the Unix domain socket part collides with something else
on an OpenSolaris system, likely Sun specific. Renaming it to _sun
(or something else of choice) fixes the build.
[mk: renamed to "s_un"]
I had this option enabled during development, but at some point, it
must have gotten lost. FAILONERROR makes the curl stream fail when
the server returns a status code 400 or higher. We are not interested
in the server's error document.
Initialize libc's locale functions. Currently, we are only interested
in LC_CTYPE (character classification), because this is what is used
by GLib's g_get_charset().
GLib provides the function g_get_filename_charsets() which determines
the file system character set. This changes MPD's fallback: GLib
prefers UTF-8 as a fallback. MPD used to fall back to ISO Latin 1.
