51 * \section intro Introduction
53 * This is the documentation for the FLAC C and C++ APIs. It is
54 * highly interconnected; this introduction should give you a top
55 * level idea of the structure and how to find the information you
56 * need. As a prerequisite you should have at least a basic
57 * knowledge of the FLAC format, documented
58 * <A HREF="../format.html">here</A>.
60 * \section c_api FLAC C API
62 * The FLAC C API is the interface to libFLAC, a set of structures
63 * describing the components of FLAC streams, and functions for
64 * encoding and decoding streams, as well as manipulating FLAC
65 * metadata in files. The public include files will be installed
66 * in your include area as <include>/FLAC/...
68 * By writing a little code and linking against libFLAC, it is
69 * relatively easy to add FLAC support to another program. The
70 * library is licensed under <A HREF="../license.html">Xiph's BSD license</A>.
71 * Complete source code of libFLAC as well as the command-line
72 * encoder and plugins is available and is a useful source of
75 * Aside from encoders and decoders, libFLAC provides a powerful
76 * metadata interface for manipulating metadata in FLAC files. It
77 * allows the user to add, delete, and modify FLAC metadata blocks
78 * and it can automatically take advantage of PADDING blocks to avoid
79 * rewriting the entire FLAC file when changing the size of the
82 * libFLAC usually only requires the standard C library and C math
83 * library. In particular, threading is not used so there is no
84 * dependency on a thread library. However, libFLAC does not use
85 * global variables and should be thread-safe.
87 * There is also a new libOggFLAC library which wraps around libFLAC
88 * to provide routines for encoding to and decoding from FLAC streams
89 * inside an Ogg container. The interfaces are very similar or identical
90 * to their counterparts in libFLAC. libOggFLAC is also licensed under
91 * <A HREF="../license.html">Xiph's BSD license</A>.
93 * \section cpp_api FLAC C++ API
95 * The FLAC C++ API is a set of classes that encapsulate the
96 * structures and functions in libFLAC. They provide slightly more
97 * functionality with respect to metadata but are otherwise
98 * equivalent. For the most part, they share the same usage as
99 * their counterparts in libFLAC, and the FLAC C API documentation
100 * can be used as a supplement. The public include files
101 * for the C++ API will be installed in your include area as
102 * <include>/FLAC++/...
104 * There is also a new libOggFLAC++ library, which provides classes
105 * for encoding to and decoding from FLAC streams in an Ogg container.
106 * The classes are very similar to their counterparts in libFLAC++.
108 * Both libFLAC++ libOggFLAC++ are also licensed under
109 * <A HREF="../license.html">Xiph's BSD license</A>.
111 * \section getting_started Getting Started
113 * A good starting point for learning the API is to browse through
114 * the <A HREF="modules.html">modules</A>. Modules are logical
115 * groupings of related functions or classes, which correspond roughly
116 * to header files or sections of header files. Each module includes a
117 * detailed description of the general usage of its functions or
120 * From there you can go on to look at the documentation of
121 * individual functions. You can see different views of the individual
122 * functions through the links in top bar across this page.
124 * \section embedded_developers Embedded Developers
126 * libFLAC has grown larger over time as more functionality has been
127 * included, but much of it may be unnecessary for a particular embedded
128 * implementation. Unused parts may be pruned by some simple editing of
129 * src/libFLAC/Makefile.am. In general, the decoders, encoders, and
130 * metadata interface are all independent from each other.
132 * It is easiest to just describe the dependencies:
134 * - All modules depend on the \link flac_format Format \endlink module.
135 * - The decoders and encoders are independent of each other.
136 * - The metadata interface requires the file decoder.
137 * - The decoder and encoder layers depend on the layers below them, but
138 * not above them; e.g. the seekable stream decoder depends on the stream
139 * decoder but not the file decoder
141 * For example, if your application only requires the stream decoder, no
142 * encoders, and no metadata interface, you can remove the seekable stream
143 * decoder, file decoder, all encoders, and the metadata interface, which
144 * will greatly reduce the size of the library.

154 * You should start with the format components as all other modules
155 * are dependent on it.
