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 Xiph's BSD license. - * 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 - * Xiph's BSD license. - * - * \section getting_started Getting Started - * - * A good starting point for learning the API is to browse through - * the modules. 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 - * example code. - * - * \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 \#defines in \c export.h of each - * library's includes (e.g. \c include/FLAC/export.h). The - * \#defines mirror the libraries' - * libtool version numbers, - * 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().

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 uint32_t. - */ - -/** \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 function is now renamed and properly integrated as - * FLAC__stream_decoder_get_client_data - * - * To accomodate encoding and decoding 32-bit int PCM, some data types - * in the \b FLAC__frame struct were changed.

Also, value - * in the FLAC__Subframe_Constant is changed from FLAC__int32 to - * FLAC__int64. Finally, in FLAC__Subframe_Verbatim struct data is - * changes from a FLAC__int32 array to a union containing a FLAC__int32 - * array and a FLAC__int64 array. Also, a new member is added, - * data_type, which clarifies whether the FLAC__int32 or FLAC__int64 - * array is in use. - * - * Furthermore, the following functions now return the object untouched - * if memory allocation fails, whereas previously the handling varied - * and was more or less undefined - * - * - FLAC__metadata_object_seektable_resize_points - * - FLAC__metadata_object_vorbiscomment_resize_comments - * - FLAC__metadata_object_cuesheet_track_resize_indices - * - FLAC__metadata_object_cuesheet_resize_tracks - * - * The last breaking change is that all API functions taking a filename - * as an argument now, on Windows, must be supplied with that filename - * in the UTF-8 character encoding instead of using the current code - * page. libFLAC internally translates these UTF-8 encoded filenames to - * an appropriate representation to use with _wfopen.

This level is write- - * efficient in most cases (more on this below), and uses less memory - * than level 2. - * - * Level 2: - * Read-write access to all metadata blocks. This level is write- - * efficient in all cases, but uses more memory since all metadata for - * the whole file is read into memory and manipulated before writing - * out again. - * - * What do we mean by efficient? Since FLAC metadata appears at the - * beginning of the file, when writing metadata back to a FLAC file - * it is possible to grow or shrink the metadata such that the entire - * file must be rewritten. However, if the size remains the same during - * changes or PADDING blocks are utilized, only the metadata needs to be - * overwritten, which is much faster. - * - * Efficient means the whole file is rewritten at most one time, and only - * when necessary. Level 1 is not efficient only in the case that you - * cause more than one metadata block to grow or shrink beyond what can - * be accommodated by padding. In this case you should probably use level - * 2, which allows you to edit all the metadata for a file in memory and - * write it out all at once. - * - * All levels know how to skip over and not disturb an ID3v2 tag at the - * front of the file. - * - * All levels access files via their filenames. In addition, level 2 - * has additional alternative read and write functions that take an I/O - * handle and callbacks, for situations where access by filename is not - * possible. - * - * In addition to the three interfaces, this module defines functions for - * creating and manipulating various metadata objects in memory. As we see - * from the Format module, FLAC metadata blocks in memory are very primitive - * structures for storing information in an efficient way. Reading - * information from the structures is easy but creating or modifying them - * directly is more complex. The metadata object routines here facilitate - * this by taking care of the consistency and memory management drudgery. - * - * Unless you will be using the level 1 or 2 interfaces to modify existing - * metadata however, you will not probably not need these. - * - * From a dependency standpoint, none of the encoders or decoders require - * the metadata module. This is so that embedded users can strip out the - * metadata module from libFLAC to reduce the size and complexity. - */ - -#ifdef __cplusplus -extern "C" { -#endif - - -/** \defgroup flac_metadata_level0 FLAC/metadata.h: metadata level 0 interface - * \ingroup flac_metadata - * - * \brief - * The level 0 interface consists of individual routines to read the - * STREAMINFO, VORBIS_COMMENT, CUESHEET, and PICTURE blocks, requiring - * only a filename. - * - * On Windows, filename must be a UTF-8 encoded filename, which libFLAC - * internally translates to an appropriate representation to use with - * _wfopen.

We decree that all pointers to data in the object are - * owned by the object and memory-managed by the object. - * - * Use the FLAC__metadata_object_new() and FLAC__metadata_object_delete() - * functions to create all instances. When using the - * FLAC__metadata_object_set_*() functions to set pointers to data, set - * \a copy to \c true to have the function make it's own copy of the data, or - * to \c false to give the object ownership of your data. In the latter case - * your pointer must be freeable by free() and will be free()d when the object - * is FLAC__metadata_object_delete()d. It is legal to pass a null pointer as - * the data pointer to a FLAC__metadata_object_set_*() function as long as - * the length argument is 0 and the \a copy argument is \c false. - * - * The FLAC__metadata_object_new() and FLAC__metadata_object_clone() function - * will return \c NULL in the case of a memory allocation error, otherwise a new - * object.

This is not counted - * toward the length or stored in the stream, but it can make working with plain - * comments (those that don't contain embedded-NULs in the value) easier. - * Entries passed into these functions have trailing NULs added if missing, and - * returned entries are guaranteed to have a trailing NUL. - * - * The FLAC__metadata_object_vorbiscomment_*() functions that take a Vorbis - * comment entry/name/value will first validate that it complies with the Vorbis - * comment specification and return false if it does not. - * - * There is no need to recalculate the length field on metadata blocks you - * have modified.

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. - * - * \{ - */ - - -/** State values for a FLAC__StreamDecoder - * - * The decoder's state can be obtained by calling FLAC__stream_decoder_get_state(). - */ -typedef enum { - - FLAC__STREAM_DECODER_SEARCH_FOR_METADATA = 0, - /**< The decoder is ready to search for metadata. */ - - FLAC__STREAM_DECODER_READ_METADATA, - /**< The decoder is ready to or is in the process of reading metadata. */ - - FLAC__STREAM_DECODER_SEARCH_FOR_FRAME_SYNC, - /**< The decoder is ready to or is in the process of searching for the - * frame sync code. - */ - - FLAC__STREAM_DECODER_READ_FRAME, - /**< The decoder is ready to or is in the process of reading a frame. */ - - FLAC__STREAM_DECODER_END_OF_STREAM, - /**< The decoder has reached the end of the stream. */ - - FLAC__STREAM_DECODER_OGG_ERROR, - /**< An error occurred in the underlying Ogg layer. */ - - FLAC__STREAM_DECODER_SEEK_ERROR, - /**< An error occurred while seeking.

At a minimum, the following - * functions should be called: - * - FLAC__stream_encoder_set_channels() - * - FLAC__stream_encoder_set_bits_per_sample() - * - FLAC__stream_encoder_set_sample_rate() - * - FLAC__stream_encoder_set_ogg_serial_number() (if encoding to Ogg FLAC) - * - FLAC__stream_encoder_set_total_samples_estimate() (if known) - * - If the application wants to control the compression level or set its own - * metadata, then the following should also be called: - * - FLAC__stream_encoder_set_compression_level() - * - FLAC__stream_encoder_set_verify() - * - FLAC__stream_encoder_set_metadata() - * - The rest of the set functions should only be called if the client needs - * exact control over how the audio is compressed; thorough understanding - * of the FLAC format is necessary to achieve good results. - * - The program initializes the instance to validate the settings and - * prepare for encoding using - * - FLAC__stream_encoder_init_stream() or FLAC__stream_encoder_init_FILE() - * or FLAC__stream_encoder_init_file() for native FLAC - * - FLAC__stream_encoder_init_ogg_stream() or FLAC__stream_encoder_init_ogg_FILE() - * or FLAC__stream_encoder_init_ogg_file() for Ogg FLAC - * - The program calls FLAC__stream_encoder_process() or - * FLAC__stream_encoder_process_interleaved() to encode data, which - * subsequently calls the callbacks when there is encoder data ready - * to be written. - * - The program finishes the encoding with FLAC__stream_encoder_finish(), - * which causes the encoder to encode any data still in its input pipe, - * update the metadata with the final encoding statistics if output - * seeking is possible, and finally reset the encoder to the - * uninitialized state. - * - The instance may be used again or deleted with - * FLAC__stream_encoder_delete(). - * - * In more detail, the stream encoder functions similarly to the - * \link flac_stream_decoder stream decoder \endlink, but has fewer - * callbacks and more options. Typically the client will create a new - * instance by calling FLAC__stream_encoder_new(), then set the necessary - * parameters with FLAC__stream_encoder_set_*(), and initialize it by - * calling one of the FLAC__stream_encoder_init_*() functions. - * - * Unlike the decoders, the stream encoder has many options that can - * affect the speed and compression ratio. When setting these parameters - * you should have some basic knowledge of the format (see the - * user-level documentation - * or the formal description). The - * FLAC__stream_encoder_set_*() functions themselves do not validate the - * values as many are interdependent. The FLAC__stream_encoder_init_*() - * functions will do this, so make sure to pay attention to the state - * returned by FLAC__stream_encoder_init_*() to make sure that it is - * FLAC__STREAM_ENCODER_INIT_STATUS_OK. Any parameters that are not set - * before FLAC__stream_encoder_init_*() will take on the defaults from - * the constructor. - * - * There are three initialization functions for native FLAC, one for - * setting up the encoder to encode FLAC data to the client via - * callbacks, and two for encoding directly to a file. - * - * For encoding via callbacks, use FLAC__stream_encoder_init_stream(). - * You must also supply a write callback which will be called anytime - * there is raw encoded data to write. If the client can seek the output - * it is best to also supply seek and tell callbacks, as this allows the - * encoder to go back after encoding is finished to write back - * information that was collected while encoding, like seek point offsets, - * frame sizes, etc. - * - * For encoding directly to a file, use FLAC__stream_encoder_init_FILE() - * or FLAC__stream_encoder_init_file(). Then you must only supply a - * filename or open \c FILE*; the encoder will handle all the callbacks - * internally. You may also supply a progress callback for periodic - * notification of the encoding progress. - * - * There are three similarly-named init functions for encoding to Ogg - * FLAC streams. Check \c FLAC_API_SUPPORTS_OGG_FLAC to find out if the - * library has been built with Ogg support. - * - * The call to FLAC__stream_encoder_init_*() currently will also immediately - * call the write callback several times, once with the \c fLaC signature, - * and once for each encoded metadata block. Note that for Ogg FLAC - * encoding you will usually get at least twice the number of callbacks than - * with native FLAC, one for the Ogg page header and one for the page body. - * - * After initializing the instance, the client may feed audio data to the - * encoder in one of two ways: - * - * - Channel separate, through FLAC__stream_encoder_process() - The client - * will pass an array of pointers to buffers, one for each channel, to - * the encoder, each of the same length. The samples need not be - * block-aligned, but each channel should have the same number of samples. - * - Channel interleaved, through - * FLAC__stream_encoder_process_interleaved() - The client will pass a single - * pointer to data that is channel-interleaved (i.e. channel0_sample0, - * channel1_sample0, ... , channelN_sample0, channel0_sample1, ...). - * Again, the samples need not be block-aligned but they must be - * sample-aligned, i.e. the first value should be channel0_sample0 and - * the last value channelN_sampleM. - * - * Note that for either process call, each sample in the buffers should be a - * signed integer, right-justified to the resolution set by - * FLAC__stream_encoder_set_bits_per_sample(). For example, if the resolution - * is 16 bits per sample, the samples should all be in the range [-32768,32767]. - * - * When the client is finished encoding data, it calls - * FLAC__stream_encoder_finish(), which causes the encoder to encode any - * data still in its input pipe, and call the metadata callback with the - * final encoding statistics. Then the instance may be deleted with - * FLAC__stream_encoder_delete() or initialized again to encode another - * stream. - * - * For programs that write their own metadata, but that do not know the - * actual metadata until after encoding, it is advantageous to instruct - * the encoder to write a PADDING block of the correct size, so that - * instead of rewriting the whole stream after encoding, the program can - * just overwrite the PADDING block. If only the maximum size of the - * metadata is known, the program can write a slightly larger padding - * block, then split it after encoding. - * - * Make sure you understand how lengths are calculated. All FLAC metadata - * blocks have a 4 byte header which contains the type and length. This - * length does not include the 4 bytes of the header. See the format page - * for the specification of metadata blocks and their lengths. - * - * \note - * If you are writing the FLAC data to a file via callbacks, make sure it - * is open for update (e.g. mode "w+" for stdio streams). This is because - * after the first encoding pass, the encoder will try to seek back to the - * beginning of the stream, to the STREAMINFO block, to write some data - * there. (If using FLAC__stream_encoder_init*_file() or - * FLAC__stream_encoder_init*_FILE(), the file is managed internally.) - * - * \note - * The "set" functions may only be called when the encoder is in the - * state FLAC__STREAM_ENCODER_UNINITIALIZED, i.e. after - * FLAC__stream_encoder_new() or FLAC__stream_encoder_finish(), but - * before FLAC__stream_encoder_init_*(). If this is the case they will - * return \c true, otherwise \c false. - * - * \note - * FLAC__stream_encoder_finish() resets all settings to the constructor - * defaults. - * - * \{ - */ - - -/** State values for a FLAC__StreamEncoder. - * - * The encoder's state can be obtained by calling FLAC__stream_encoder_get_state(). - * - * If the encoder gets into any other state besides \c FLAC__STREAM_ENCODER_OK - * or \c FLAC__STREAM_ENCODER_UNINITIALIZED, it becomes invalid for encoding and - * must be deleted with FLAC__stream_encoder_delete(). - */ -typedef enum { - - FLAC__STREAM_ENCODER_OK = 0, - /**< The encoder is in the normal OK state and samples can be processed. */ - - FLAC__STREAM_ENCODER_UNINITIALIZED, - /**< The encoder is in the uninitialized state; one of the - * FLAC__stream_encoder_init_*() functions must be called before samples - * can be processed. - */ - - FLAC__STREAM_ENCODER_OGG_ERROR, - /**< An error occurred in the underlying Ogg layer. */ - - FLAC__STREAM_ENCODER_VERIFY_DECODER_ERROR, - /**< An error occurred in the underlying verify stream decoder; - * check FLAC__stream_encoder_get_verify_decoder_state(). - */ - - FLAC__STREAM_ENCODER_VERIFY_MISMATCH_IN_AUDIO_DATA, - /**< The verify decoder detected a mismatch between the original - * audio signal and the decoded audio signal. - */ - - FLAC__STREAM_ENCODER_CLIENT_ERROR, - /**< One of the callbacks returned a fatal error. */ - - FLAC__STREAM_ENCODER_IO_ERROR, - /**< An I/O error occurred while opening/reading/writing a file. - * Check \c errno. - */ - - FLAC__STREAM_ENCODER_FRAMING_ERROR, - /**< An error occurred while writing the stream; usually, the - * write_callback returned an error. - */ - - FLAC__STREAM_ENCODER_MEMORY_ALLOCATION_ERROR - /**< Memory allocation failed. */ - -} FLAC__StreamEncoderState; - -/** Maps a FLAC__StreamEncoderState to a C string. - * - * Using a FLAC__StreamEncoderState as the index to this array - * will give the string equivalent.
