AVUtil ====== libavutil is a small lightweight library of generally useful functions. It is not a library for code needed by both libavcodec and libavformat. Overview: ========= adler32.c adler32 checksum aes.c AES encryption and decryption fifo.c resizeable first in first out buffer intfloat_readwrite.c portable reading and writing of floating point values log.c "printf" with context and level md5.c MD5 Message-Digest Algorithm rational.c code to perform exact calculations with rational numbers tree.c generic AVL tree crc.c generic CRC checksumming code integer.c 128bit integer math lls.c mathematics.c greatest common divisor, integer sqrt, integer log2, ... mem.c memory allocation routines with guaranteed alignment Headers: bswap.h big/little/native-endian conversion code x86_cpu.h a few useful macros for unifying x86-64 and x86-32 code avutil.h common.h intreadwrite.h reading and writing of unaligned big/little/native-endian integers Goals: ====== * Modular (few interdependencies and the possibility of disabling individual parts during ./configure) * Small (source and object) * Efficient (low CPU and memory usage) * Useful (avoid useless features almost no one needs)
