-/** \mainpage
- *
- * \section intro Introduction
- *
- * This is the documentation for the FLAC C and C++ APIs.  It is
- * highly interconnected; this introduction should give you a top
- * level idea of the structure and how to find the information you
- * need.  As a prerequisite you should have at least a basic
- * knowledge of the FLAC format, documented
- * <A HREF="../format.html">here</A>.
- *
- * \section c_api FLAC C API
- *
- * The FLAC C API is the interface to libFLAC, a set of structures
- * describing the components of FLAC streams, and functions for
- * encoding and decoding streams, as well as manipulating FLAC
- * metadata in files.  The public include files will be installed
- * in your include area (for example /usr/include/FLAC/...).
- *
- * By writing a little code and linking against libFLAC, it is
- * relatively easy to add FLAC support to another program.  The
- * library is licensed under <A HREF="../license.html">Xiph's BSD license</A>.
- * Complete source code of libFLAC as well as the command-line
- * encoder and plugins is available and is a useful source of
- * examples.
- *
- * Aside from encoders and decoders, libFLAC provides a powerful
- * metadata interface for manipulating metadata in FLAC files.  It
- * allows the user to add, delete, and modify FLAC metadata blocks
- * and it can automatically take advantage of PADDING blocks to avoid
- * rewriting the entire FLAC file when changing the size of the
- * metadata.
- *
- * libFLAC usually only requires the standard C library and C math
- * library. In particular, threading is not used so there is no
- * dependency on a thread library. However, libFLAC does not use
- * global variables and should be thread-safe.
- *
- * libFLAC also supports encoding to and decoding from Ogg FLAC.
- * However the metadata editing interfaces currently have limited
- * read-only support for Ogg FLAC files.
- *
- * \section cpp_api FLAC C++ API
- *
- * The FLAC C++ API is a set of classes that encapsulate the
- * structures and functions in libFLAC.  They provide slightly more
- * functionality with respect to metadata but are otherwise
- * equivalent.  For the most part, they share the same usage as
- * their counterparts in libFLAC, and the FLAC C API documentation
- * can be used as a supplement.  The public include files
- * for the C++ API will be installed in your include area (for
- * example /usr/include/FLAC++/...).
- *
- * libFLAC++ is also licensed under
- * <A HREF="../license.html">Xiph's BSD license</A>.
- *
- * \section getting_started Getting Started
- *
- * A good starting point for learning the API is to browse through
- * the <A HREF="modules.html">modules</A>.  Modules are logical
- * groupings of related functions or classes, which correspond roughly
- * to header files or sections of header files.  Each module includes a
- * detailed description of the general usage of its functions or
- * classes.
- *
- * From there you can go on to look at the documentation of
- * individual functions.  You can see different views of the individual
- * functions through the links in top bar across this page.
- *
- * If you prefer a more hands-on approach, you can jump right to some
- * <A HREF="../documentation_example_code.html">example code</A>.
- *
- * \section porting_guide Porting Guide
- *
- * Starting with FLAC 1.1.3 a \link porting Porting Guide \endlink
- * has been introduced which gives detailed instructions on how to
- * port your code to newer versions of FLAC.
- *
- * \section embedded_developers Embedded Developers
- *
- * libFLAC has grown larger over time as more functionality has been
- * included, but much of it may be unnecessary for a particular embedded
- * implementation.  Unused parts may be pruned by some simple editing of
- * src/libFLAC/Makefile.am.  In general, the decoders, encoders, and
- * metadata interface are all independent from each other.
- *
- * It is easiest to just describe the dependencies:
- *
- * - All modules depend on the \link flac_format Format \endlink module.
- * - The decoders and encoders depend on the bitbuffer.
- * - The decoder is independent of the encoder.  The encoder uses the
- *   decoder because of the verify feature, but this can be removed if
- *   not needed.
- * - Parts of the metadata interface require the stream decoder (but not
- *   the encoder).
- * - Ogg support is selectable through the compile time macro
- *   \c FLAC__HAS_OGG.
- *
- * For example, if your application only requires the stream decoder, no
- * encoder, and no metadata interface, you can remove the stream encoder
- * and the metadata interface, which will greatly reduce the size of the
- * library.
- *
- * Also, there are several places in the libFLAC code with comments marked
- * with "OPT:" where a #define can be changed to enable code that might be
- * faster on a specific platform.  Experimenting with these can yield faster
- * binaries.

-/** \defgroup porting Porting Guide for New Versions
- *
- * This module describes differences in the library interfaces from
- * version to version.  It assists in the porting of code that uses
- * the libraries to newer versions of FLAC.
- *
- * One simple facility for making porting easier that has been added
- * in FLAC 1.1.3 is a set of \c #defines in \c export.h of each
- * library's includes (e.g. \c include/FLAC/export.h).  The
- * \c #defines mirror the libraries'
- * <A HREF="http://www.gnu.org/software/libtool/manual/libtool.html#Libtool-versioning">libtool version numbers</A>,
- * e.g. in libFLAC there are \c FLAC_API_VERSION_CURRENT,
- * \c FLAC_API_VERSION_REVISION, and \c FLAC_API_VERSION_AGE.
- * These can be used to support multiple versions of an API during the
- * transition phase, e.g.
- *
- * \code
- * #if !defined(FLAC_API_VERSION_CURRENT) || FLAC_API_VERSION_CURRENT <= 7
- *   legacy code
- * #else
- *   new code
- * #endif
- * \endcode
- *
- * The source will work for multiple versions and the legacy code can
- * easily be removed when the transition is complete.
- *
- * Another available symbol is FLAC_API_SUPPORTS_OGG_FLAC (defined in
- * include/FLAC/export.h), which can be used to determine whether or not
- * the library has been compiled with support for Ogg FLAC.  This is
- * simpler than trying to call an Ogg init function and catching the
- * error.

-/** \defgroup porting_1_1_2_to_1_1_3 Porting from FLAC 1.1.2 to 1.1.3
- *  \ingroup porting
- *
- *  \brief
- *  This module describes porting from FLAC 1.1.2 to FLAC 1.1.3.
- *
- * The main change between the APIs in 1.1.2 and 1.1.3 is that they have
- * been simplified.  First, libOggFLAC has been merged into libFLAC and
- * libOggFLAC++ has been merged into libFLAC++.  Second, both the three
- * decoding layers and three encoding layers have been merged into a
- * single stream decoder and stream encoder.  That is, the functionality
- * of FLAC__SeekableStreamDecoder and FLAC__FileDecoder has been merged
- * into FLAC__StreamDecoder, and FLAC__SeekableStreamEncoder and
- * FLAC__FileEncoder into FLAC__StreamEncoder.  Only the
- * FLAC__StreamDecoder and FLAC__StreamEncoder remain.  What this means
- * is there is now a single API that can be used to encode or decode
- * streams to/from native FLAC or Ogg FLAC and the single API can work
- * on both seekable and non-seekable streams.
- *
- * Instead of creating an encoder or decoder of a certain layer, now the
- * client will always create a FLAC__StreamEncoder or
- * FLAC__StreamDecoder.  The old layers are now differentiated by the
- * initialization function.  For example, for the decoder,
- * FLAC__stream_decoder_init() has been replaced by
- * FLAC__stream_decoder_init_stream().  This init function takes
- * callbacks for the I/O, and the seeking callbacks are optional.  This
- * allows the client to use the same object for seekable and
- * non-seekable streams.  For decoding a FLAC file directly, the client
- * can use FLAC__stream_decoder_init_file() and pass just a filename
- * and fewer callbacks; most of the other callbacks are supplied
- * internally.  For situations where fopen()ing by filename is not
- * possible (e.g. Unicode filenames on Windows) the client can instead
- * open the file itself and supply the FILE* to
- * FLAC__stream_decoder_init_FILE().  The init functions now returns a
- * FLAC__StreamDecoderInitStatus instead of FLAC__StreamDecoderState.
- * Since the callbacks and client data are now passed to the init
- * function, the FLAC__stream_decoder_set_*_callback() functions and
- * FLAC__stream_decoder_set_client_data() are no longer needed.  The
- * rest of the calls to the decoder are the same as before.
- *
- * There are counterpart init functions for Ogg FLAC, e.g.
- * FLAC__stream_decoder_init_ogg_stream().  All the rest of the calls
- * and callbacks are the same as for native FLAC.
- *
- * As an example, in FLAC 1.1.2 a seekable stream decoder would have
- * been set up like so:
- *
- * \code
- * FLAC__SeekableStreamDecoder *decoder = FLAC__seekable_stream_decoder_new();
- * if(decoder == NULL) do_something;
- * FLAC__seekable_stream_decoder_set_md5_checking(decoder, true);
- * [... other settings ...]
- * FLAC__seekable_stream_decoder_set_read_callback(decoder, my_read_callback);
- * FLAC__seekable_stream_decoder_set_seek_callback(decoder, my_seek_callback);
- * FLAC__seekable_stream_decoder_set_tell_callback(decoder, my_tell_callback);
- * FLAC__seekable_stream_decoder_set_length_callback(decoder, my_length_callback);
- * FLAC__seekable_stream_decoder_set_eof_callback(decoder, my_eof_callback);
- * FLAC__seekable_stream_decoder_set_write_callback(decoder, my_write_callback);
- * FLAC__seekable_stream_decoder_set_metadata_callback(decoder, my_metadata_callback);
- * FLAC__seekable_stream_decoder_set_error_callback(decoder, my_error_callback);
- * FLAC__seekable_stream_decoder_set_client_data(decoder, my_client_data);
- * if(FLAC__seekable_stream_decoder_init(decoder) != FLAC__SEEKABLE_STREAM_DECODER_OK) do_something;
- * \endcode
- *
- * In FLAC 1.1.3 it is like this:
- *
- * \code
- * FLAC__StreamDecoder *decoder = FLAC__stream_decoder_new();
- * if(decoder == NULL) do_something;
- * FLAC__stream_decoder_set_md5_checking(decoder, true);
- * [... other settings ...]
- * if(FLAC__stream_decoder_init_stream(
- *   decoder,
- *   my_read_callback,
- *   my_seek_callback,      // or NULL
- *   my_tell_callback,      // or NULL
- *   my_length_callback,    // or NULL
- *   my_eof_callback,       // or NULL
- *   my_write_callback,
- *   my_metadata_callback,  // or NULL
- *   my_error_callback,
- *   my_client_data
- * ) != FLAC__STREAM_DECODER_INIT_STATUS_OK) do_something;
- * \endcode
- *
- * or you could do;
- *
- * \code
- * [...]
- * FILE *file = fopen("somefile.flac","rb");
- * if(file == NULL) do_somthing;
- * if(FLAC__stream_decoder_init_FILE(
- *   decoder,
- *   file,
- *   my_write_callback,
- *   my_metadata_callback,  // or NULL
- *   my_error_callback,
- *   my_client_data
- * ) != FLAC__STREAM_DECODER_INIT_STATUS_OK) do_something;
- * \endcode
- *
- * or just:
- *
- * \code
- * [...]
- * if(FLAC__stream_decoder_init_file(
- *   decoder,
- *   "somefile.flac",
- *   my_write_callback,
- *   my_metadata_callback,  // or NULL
- *   my_error_callback,
- *   my_client_data
- * ) != FLAC__STREAM_DECODER_INIT_STATUS_OK) do_something;
- * \endcode
- *
- * Another small change to the decoder is in how it handles unparseable
- * streams.  Before, when the decoder found an unparseable stream
- * (reserved for when the decoder encounters a stream from a future
- * encoder that it can't parse), it changed the state to
- * \c FLAC__STREAM_DECODER_UNPARSEABLE_STREAM.  Now the decoder instead
- * drops sync and calls the error callback with a new error code
- * \c FLAC__STREAM_DECODER_ERROR_STATUS_UNPARSEABLE_STREAM.  This is
- * more robust.  If your error callback does not discriminate on the the
- * error state, your code does not need to be changed.
- *
- * The encoder now has a new setting:
- * FLAC__stream_encoder_set_apodization().  This is for setting the
- * method used to window the data before LPC analysis.  You only need to
- * add a call to this function if the default is not suitable.   There
- * are also two new convenience functions that may be useful:
- * FLAC__metadata_object_cuesheet_calculate_cddb_id() and
- * FLAC__metadata_get_cuesheet().
- *
- * The \a bytes parameter to FLAC__StreamDecoderReadCallback,
- * FLAC__StreamEncoderReadCallback, and FLAC__StreamEncoderWriteCallback
- * is now \c size_t instead of \c unsigned.

-/** \defgroup porting_1_1_3_to_1_1_4 Porting from FLAC 1.1.3 to 1.1.4
- *  \ingroup porting
- *
- *  \brief
- *  This module describes porting from FLAC 1.1.3 to FLAC 1.1.4.
- *
- * There were no changes to any of the interfaces from 1.1.3 to 1.1.4.
- * There was a slight change in the implementation of
- * FLAC__stream_encoder_set_metadata(); the function now makes a copy
- * of the \a metadata array of pointers so the client no longer needs
- * to maintain it after the call.  The objects themselves that are
- * pointed to by the array are still not copied though and must be
- * maintained until the call to FLAC__stream_encoder_finish().
- */
-
-/** \defgroup porting_1_1_4_to_1_2_0 Porting from FLAC 1.1.4 to 1.2.0
- *  \ingroup porting
- *
- *  \brief
- *  This module describes porting from FLAC 1.1.4 to FLAC 1.2.0.
- *
- * There were only very minor changes to the interfaces from 1.1.4 to 1.2.0.
- * In libFLAC, \c FLAC__format_sample_rate_is_subset() was added.
- * In libFLAC++, \c FLAC::Decoder::Stream::get_decode_position() was added.
- *
- * Finally, value of the constant \c FLAC__FRAME_HEADER_RESERVED_LEN
- * has changed to reflect the conversion of one of the reserved bits
- * into active use.  It used to be \c 2 and now is \c 1.  However the
- * FLAC frame header length has not changed, so to skip the proper
- * number of bits, use \c FLAC__FRAME_HEADER_RESERVED_LEN +
- * \c FLAC__FRAME_HEADER_BLOCKING_STRATEGY_LEN

-	 * but how much it asks for depends on how much free space it has in
-	 * its internal buffer.  It does not try to grow its internal buffer
-	 * to accomodate a whole frame because then the internal buffer size
-	 * could not be limited, which is necessary in embedded applications.
-	 *
-	 * Ogg however grows its internal buffer until a whole page is present;
-	 * only then can you get decoded data out.  So we can't just ask for
-	 * the same number of bytes from Ogg, then pass what's decoded down to
-	 * libFLAC.  If what libFLAC is asking for will not contain a whole
-	 * page, then we will get no data from ogg_sync_pageout(), and at the
-	 * same time cannot just read more data from the client for the purpose
-	 * of getting a whole decoded page because the decoded size might be
-	 * larger than libFLAC's internal buffer.
-	 *
-	 * Instead, whenever this read callback wrapper is called, we will
-	 * continually request data from the client until we have at least one
-	 * page, and manage pages internally so that we can send pieces of
-	 * pages down to libFLAC in such a way that we obey its size
-	 * requirement.  To limit the amount of callbacks, we will always try

-
-; see src/libFLAC/lpc.c:FLAC__lpc_restore_signal()
-; these is a PowerPC/Altivec assembly version which requires bps<=16 (or actual
-; bps<=15 for mid-side coding, since that uses an extra bit)
-
-; these should be fast; the inner loop is unrolled (it takes no more than
-; 3*(order%4) instructions, all of which are arithmetic), and all of the
-; coefficients and all relevant history stay in registers, so the outer loop
-; has only one load from memory (the residual)
-
-; I have not yet run this through simg4, so there may be some avoidable stalls,
-; and there may be a somewhat more clever way to do the outer loop
-
-; the branch mechanism may prevent dynamic loading; I still need to examine
-; this issue, and there may be a more elegant method
