+ *
+ * The stream decoder can be used to decode complete streams either from
+ * the client via callbacks, or directly from a file, depending on how
+ * it is initialized.  When decoding via callbacks, the client provides
+ * callbacks for reading FLAC data and writing decoded samples, and
+ * handling metadata and errors.  If the client also supplies seek-related
+ * callback, the decoder function for sample-accurate seeking within the
+ * FLAC input is also available.  When decoding from a file, the client
+ * needs only supply a filename or open \c FILE* and write/metadata/error
+ * callbacks; the rest of the callbacks are supplied internally.  For more
+ * info see the \link flac_stream_decoder stream decoder \endlink module.

+/** \defgroup flac_stream_decoder FLAC/stream_decoder.h: stream decoder interface
+ *  \ingroup flac_decoder
+ *
+ *  \brief
+ *  This module contains the functions which implement the stream
+ *  decoder.
+ *
+ * The stream decoder can decode native FLAC, and optionally Ogg FLAC
+ * (check FLAC_API_SUPPORTS_OGG_FLAC) streams and files.
+ *
+ * The basic usage of this decoder is as follows:
+ * - The program creates an instance of a decoder using
+ *   FLAC__stream_decoder_new().
+ * - The program overrides the default settings using
+ *   FLAC__stream_decoder_set_*() functions.
+ * - The program initializes the instance to validate the settings and
+ *   prepare for decoding using
+ *   - FLAC__stream_decoder_init_stream() or FLAC__stream_decoder_init_FILE()
+ *     or FLAC__stream_decoder_init_file() for native FLAC,
+ *   - FLAC__stream_decoder_init_ogg_stream() or FLAC__stream_decoder_init_ogg_FILE()
+ *     or FLAC__stream_decoder_init_ogg_file() for Ogg FLAC
+ * - The program calls the FLAC__stream_decoder_process_*() functions
+ *   to decode data, which subsequently calls the callbacks.
+ * - The program finishes the decoding with FLAC__stream_decoder_finish(),
+ *   which flushes the input and output and resets the decoder to the
+ *   uninitialized state.
+ * - The instance may be used again or deleted with
+ *   FLAC__stream_decoder_delete().
+ *
+ * In more detail, the program will create a new instance by calling
+ * FLAC__stream_decoder_new(), then call FLAC__stream_decoder_set_*()
+ * functions to override the default decoder options, and call
+ * one of the FLAC__stream_decoder_init_*() functions.
+ *
+ * There are three initialization functions for native FLAC, one for
+ * setting up the decoder to decode FLAC data from the client via
+ * callbacks, and two for decoding directly from a FLAC file.
+ *
+ * For decoding via callbacks, use FLAC__stream_decoder_init_stream().
+ * You must also supply several callbacks for handling I/O.  Some (like
+ * seeking) are optional, depending on the capabilities of the input.
+ *
+ * For decoding directly from a file, use FLAC__stream_decoder_init_FILE()
+ * or FLAC__stream_decoder_init_file().  Then you must only supply an open
+ * \c FILE* or filename and fewer callbacks; the decoder will handle
+ * the other callbacks internally.
+ *
+ * There are three similarly-named init functions for decoding from Ogg
+ * FLAC streams.  Check \c FLAC_API_SUPPORTS_OGG_FLAC to find out if the
+ * library has been built with Ogg support.
+ *
+ * Once the decoder is initialized, your program will call one of several
+ * functions to start the decoding process:
+ *
+ * - FLAC__stream_decoder_process_single() - Tells the decoder to process at
+ *   most one metadata block or audio frame and return, calling either the
+ *   metadata callback or write callback, respectively, once.  If the decoder
+ *   loses sync it will return with only the error callback being called.
+ * - FLAC__stream_decoder_process_until_end_of_metadata() - Tells the decoder
+ *   to process the stream from the current location and stop upon reaching
+ *   the first audio frame.  The client will get one metadata, write, or error
+ *   callback per metadata block, audio frame, or sync error, respectively.
+ * - FLAC__stream_decoder_process_until_end_of_stream() - Tells the decoder
+ *   to process the stream from the current location until the read callback
+ *   returns FLAC__STREAM_DECODER_READ_STATUS_END_OF_STREAM or
+ *   FLAC__STREAM_DECODER_READ_STATUS_ABORT.  The client will get one metadata,
+ *   write, or error callback per metadata block, audio frame, or sync error,
+ *   respectively.
+ *
+ * When the decoder has finished decoding (normally or through an abort),
+ * the instance is finished by calling FLAC__stream_decoder_finish(), which
+ * ensures the decoder is in the correct state and frees memory.  Then the
+ * instance may be deleted with FLAC__stream_decoder_delete() or initialized
+ * again to decode another stream.
+ *
+ * Seeking is exposed through the FLAC__stream_decoder_seek_absolute() method.
+ * At any point after the stream decoder has been initialized, the client can
+ * call this function to seek to an exact sample within the stream.
+ * Subsequently, the first time the write callback is called it will be
+ * passed a (possibly partial) block starting at that sample.
+ *
+ * If the client cannot seek via the callback interface provided, but still
+ * has another way of seeking, it can flush the decoder using
+ * FLAC__stream_decoder_flush() and start feeding data from the new position
+ * through the read callback.
+ *
+ * The stream decoder also provides MD5 signature checking.  If this is
+ * turned on before initialization, FLAC__stream_decoder_finish() will
+ * report when the decoded MD5 signature does not match the one stored
+ * in the STREAMINFO block.  MD5 checking is automatically turned off
+ * (until the next FLAC__stream_decoder_reset()) if there is no signature
+ * in the STREAMINFO block or when a seek is attempted.
+ *
+ * The FLAC__stream_decoder_set_metadata_*() functions deserve special
+ * attention.  By default, the decoder only calls the metadata_callback for
+ * the STREAMINFO block.  These functions allow you to tell the decoder
+ * explicitly which blocks to parse and return via the metadata_callback
+ * and/or which to skip.  Use a FLAC__stream_decoder_set_metadata_respond_all(),
+ * FLAC__stream_decoder_set_metadata_ignore() ... or FLAC__stream_decoder_set_metadata_ignore_all(),
+ * FLAC__stream_decoder_set_metadata_respond() ... sequence to exactly specify
+ * which blocks to return.  Remember that metadata blocks can potentially
+ * be big (for example, cover art) so filtering out the ones you don't
+ * use can reduce the memory requirements of the decoder.  Also note the
+ * special forms FLAC__stream_decoder_set_metadata_respond_application(id)
+ * and FLAC__stream_decoder_set_metadata_ignore_application(id) for
+ * filtering APPLICATION blocks based on the application ID.
+ *
+ * STREAMINFO and SEEKTABLE blocks are always parsed and used internally, but
+ * they still can legally be filtered from the metadata_callback.
+ *
+ * \note
+ * The "set" functions may only be called when the decoder is in the
+ * state FLAC__STREAM_DECODER_UNINITIALIZED, i.e. after
+ * FLAC__stream_decoder_new() or FLAC__stream_decoder_finish(), but
+ * before FLAC__stream_decoder_init_*().  If this is the case they will
+ * return \c true, otherwise \c false.
+ *
+ * \note
+ * FLAC__stream_decoder_finish() resets all settings to the constructor
+ * defaults, including the callbacks.
