The major version - * number is incremented with backward incompatible changes - e.g. removing - * parts of the public API, reordering public struct members, etc. The minor - * version number is incremented for backward compatible API changes or major - * new features - e.g. adding a new public function or a new decoder. The micro - * version number is incremented for smaller changes that a calling program - * might still want to check for - e.g. changing behavior in a previously - * unspecified situation. - * - * FFmpeg guarantees backward API and ABI compatibility for each library as long - * as its major version number is unchanged. This means that no public symbols - * will be removed or renamed. Types and names of the public struct members and - * values of public macros and enums will remain the same (unless they were - * explicitly declared as not part of the public API). Documented behavior will - * not change. - * - * In other words, any correct program that works with a given FFmpeg snapshot - * should work just as well without any changes with any later snapshot with the - * same major versions. This applies to both rebuilding the program against new - * FFmpeg versions or to replacing the dynamic FFmpeg libraries that a program - * links against. - * - * However, new public symbols may be added and new members may be appended to - * public structs whose size is not part of public ABI (most public structs in - * FFmpeg). New macros and enum values may be added. Behavior in undocumented - * situations may change slightly (and be documented). All those are accompanied - * by an entry in doc/APIchanges and incrementing either the minor or micro - * version number. - */ - -/** - * @defgroup lavu Common utility functions - * - * @brief - * libavutil contains the code shared across all the other FFmpeg - * libraries - * - * @note In order to use the functions provided by avutil you must include - * the specific header. - * - * @{ - * - * @defgroup lavu_crypto Crypto and Hashing - * - * @{ - * @} - * - * @defgroup lavu_math Maths - * @{ - * - * @} - * - * @defgroup lavu_string String Manipulation - * - * @{ - * - * @} - * - * @defgroup lavu_mem Memory Management - * - * @{ - * - * @} - * - * @defgroup lavu_data Data Structures - * @{ - * - * @} - * - * @defgroup lavu_audio Audio related - * - * @{ - * - * @} - * - * @defgroup lavu_error Error Codes - * - * @{ - * - * @} - * - * @defgroup lavu_log Logging Facility - * - * @{ - * - * @} - * - * @defgroup lavu_misc Other - * - * @{ - * - * @defgroup preproc_misc Preprocessor String Macros - * - * @{ - * - * @} - * - * @defgroup version_utils Library Version Macros - * - * @{ - * - * @} - */ - - -/** - * @addtogroup lavu_ver - * @{ - */ - -/** - * Return the LIBAVUTIL_VERSION_INT constant. - */ -unsigned avutil_version(void); - -/** - * Return an informative version string.
