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 - * here. - * - * \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 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 \c #defines in \c export.h of each - * library's includes (e.g. \c include/FLAC/export.h). The - * \c #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 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.

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 accomodated 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. - * - * They try to skip any ID3v2 tag at the head of the file. - * - * \{ - */ - -/** Read the STREAMINFO metadata block of the given FLAC file.

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. The FLAC__metadata_object_set_*() functions return \c false in the - * case of a memory allocation error. - * - * We don't have the convenience of C++ here, so note that the library relies - * on you to keep the types straight. In other words, if you pass, for - * example, a FLAC__StreamMetadata* that represents a STREAMINFO block to - * FLAC__metadata_object_application_set_data(), you will get an assertion - * failure. - * - * For convenience the FLAC__metadata_object_vorbiscomment_*() functions - * maintain a trailing NUL on each Vorbis comment entry. 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.

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.

The +existing system of DRFLAC_MALLOC, DRFLAC_REALLOC and DRFLAC_FREE are still in place and will be used by default when no custom +allocation callbacks are specified. + +To use the new system, you pass in a pointer to a drflac_allocation_callbacks object to drflac_open() and family, like this: + + void* my_malloc(size_t sz, void* pUserData) + { + return malloc(sz); + } + void* my_realloc(void* p, size_t sz, void* pUserData) + { + return realloc(p, sz); + } + void my_free(void* p, void* pUserData) + { + free(p); + } + + ... + + drflac_allocation_callbacks allocationCallbacks; + allocationCallbacks.pUserData = &myData; + allocationCallbacks.onMalloc = my_malloc; + allocationCallbacks.onRealloc = my_realloc; + allocationCallbacks.onFree = my_free; + drflac* pFlac = drflac_open_file("my_file.flac", &allocationCallbacks); + +The advantage of this new system is that it allows you to specify user data which will be passed in to the allocation routines. + +Passing in null for the allocation callbacks object will cause dr_flac to use defaults which is the same as DRFLAC_MALLOC, +DRFLAC_REALLOC and DRFLAC_FREE and the equivalent of how it worked in previous versions. + +Every API that opens a drflac object now takes this extra parameter. These include the following: + + drflac_open() + drflac_open_relaxed() + drflac_open_with_metadata() + drflac_open_with_metadata_relaxed() + drflac_open_file() + drflac_open_file_with_metadata() + drflac_open_memory() + drflac_open_memory_with_metadata() + drflac_open_and_read_pcm_frames_s32() + drflac_open_and_read_pcm_frames_s16() + drflac_open_and_read_pcm_frames_f32() + drflac_open_file_and_read_pcm_frames_s32() + drflac_open_file_and_read_pcm_frames_s16() + drflac_open_file_and_read_pcm_frames_f32() + drflac_open_memory_and_read_pcm_frames_s32() + drflac_open_memory_and_read_pcm_frames_s16() + drflac_open_memory_and_read_pcm_frames_f32() + + + +Optimizations +------------- +Seeking performance has been greatly improved. A new binary search based seeking algorithm has been introduced which significantly +improves performance over the brute force method which was used when no seek table was present. Seek table based seeking also takes +advantage of the new binary search seeking system to further improve performance there as well. Note that this depends on CRC which +means it will be disabled when DR_FLAC_NO_CRC is used. + +The SSE4.1 pipeline has been cleaned up and optimized. You should see some improvements with decoding speed of 24-bit files in +particular. 16-bit streams should also see some improvement. + +drflac_read_pcm_frames_s16() has been optimized. Previously this sat on top of drflac_read_pcm_frames_s32() and performed it's s32 +to s16 conversion in a second pass. This is now all done in a single pass. This includes SSE2 and ARM NEON optimized paths. + +A minor optimization has been implemented for drflac_read_pcm_frames_s32(). This will now use an SSE2 optimized pipeline for stereo +channel reconstruction which is the last part of the decoding process. + +The ARM build has seen a few improvements. The CLZ (count leading zeroes) and REV (byte swap) instructions are now used when +compiling with GCC and Clang which is achieved using inline assembly. The CLZ instruction requires ARM architecture version 5 at +compile time and the REV instruction requires ARM architecture version 6. + +An ARM NEON optimized pipeline has been implemented. To enable this you'll need to add -mfpu=neon to the command line when compiling. + + +Removed APIs +------------ +The following APIs were deprecated in version 0.11.0 and have been completely removed in version 0.12.0: + + drflac_read_s32() -> drflac_read_pcm_frames_s32() + drflac_read_s16() -> drflac_read_pcm_frames_s16() + drflac_read_f32() -> drflac_read_pcm_frames_f32() + drflac_seek_to_sample() -> drflac_seek_to_pcm_frame() + drflac_open_and_decode_s32() -> drflac_open_and_read_pcm_frames_s32() + drflac_open_and_decode_s16() -> drflac_open_and_read_pcm_frames_s16() + drflac_open_and_decode_f32() -> drflac_open_and_read_pcm_frames_f32() + drflac_open_and_decode_file_s32() -> drflac_open_file_and_read_pcm_frames_s32() + drflac_open_and_decode_file_s16() -> drflac_open_file_and_read_pcm_frames_s16() + drflac_open_and_decode_file_f32() -> drflac_open_file_and_read_pcm_frames_f32() + drflac_open_and_decode_memory_s32() -> drflac_open_memory_and_read_pcm_frames_s32() + drflac_open_and_decode_memory_s16() -> drflac_open_memory_and_read_pcm_frames_s16() + drflac_open_and_decode_memory_f32() -> drflac_open_memroy_and_read_pcm_frames_f32() + +Prior versions of dr_flac operated on a per-sample basis whereas now it operates on PCM frames. The removed APIs all relate +to the old per-sample APIs. You now need to use the "pcm_frame" versions. +*/ + + +/* +Introduction +============ +dr_flac is a single file library. To use it, do something like the following in one .c file. + + ```c + #define DR_FLAC_IMPLEMENTATION + #include "dr_flac.h" + ``` + +You can then #include this file in other parts of the program as you would with any other header file. To decode audio data, do something like the following: + + ```c + drflac* pFlac = drflac_open_file("MySong.flac", NULL); + if (pFlac == NULL) { + // Failed to open FLAC file + } + + drflac_int32* pSamples = malloc(pFlac->totalPCMFrameCount * pFlac->channels * sizeof(drflac_int32)); + drflac_uint64 numberOfInterleavedSamplesActuallyRead = drflac_read_pcm_frames_s32(pFlac, pFlac->totalPCMFrameCount, pSamples); + ``` + +The drflac object represents the decoder. It is a transparent type so all the information you need, such as the number of channels and the bits per sample, +should be directly accessible - just make sure you don't change their values. Samples are always output as interleaved signed 32-bit PCM. In the example above +a native FLAC stream was opened, however dr_flac has seamless support for Ogg encapsulated FLAC streams as well. + +You do not need to decode the entire stream in one go - you just specify how many samples you'd like at any given time and the decoder will give you as many +samples as it can, up to the amount requested. Later on when you need the next batch of samples, just call it again. Example: + + ```c + while (drflac_read_pcm_frames_s32(pFlac, chunkSizeInPCMFrames, pChunkSamples) > 0) { + do_something(); + } + ``` + +You can seek to a specific PCM frame with `drflac_seek_to_pcm_frame()`. + +If you just want to quickly decode an entire FLAC file in one go you can do something like this: + + ```c + unsigned int channels; + unsigned int sampleRate; + drflac_uint64 totalPCMFrameCount; + drflac_int32* pSampleData = drflac_open_file_and_read_pcm_frames_s32("MySong.flac", &channels, &sampleRate, &totalPCMFrameCount, NULL); + if (pSampleData == NULL) { + // Failed to open and decode FLAC file. + } + + ... + + drflac_free(pSampleData, NULL); + ``` + +You can read samples as signed 16-bit integer and 32-bit floating-point PCM with the *_s16() and *_f32() family of APIs respectively, but note that these +should be considered lossy. + + +If you need access to metadata (album art, etc.), use `drflac_open_with_metadata()`, `drflac_open_file_with_metdata()` or `drflac_open_memory_with_metadata()`. +The rationale for keeping these APIs separate is that they're slightly slower than the normal versions and also just a little bit harder to use. dr_flac +reports metadata to the application through the use of a callback, and every metadata block is reported before `drflac_open_with_metdata()` returns. + +The main opening APIs (`drflac_open()`, etc.) will fail if the header is not present. The presents a problem in certain scenarios such as broadcast style +streams or internet radio where the header may not be present because the user has started playback mid-stream. To handle this, use the relaxed APIs: + + `drflac_open_relaxed()` + `drflac_open_with_metadata_relaxed()` + +It is not recommended to use these APIs for file based streams because a missing header would usually indicate a corrupt or perverse file. In addition, these +APIs can take a long time to initialize because they may need to spend a lot of time finding the first frame. + + + +Build Options +============= +#define these options before including this file. + +#define DR_FLAC_NO_STDIO + Disable `drflac_open_file()` and family. + +#define DR_FLAC_NO_OGG + Disables support for Ogg/FLAC streams. + +#define DR_FLAC_BUFFER_SIZE + Defines the size of the internal buffer to store data from onRead().
