The libavutil library is a utility library to aid portable multimedia programming. It contains safe portable string functions, random number generators, data structures, additional mathematics functions, cryptography and multimedia related functionality (like enumerations for pixel and sample formats). It is not a library for code needed by both libavcodec and libavformat.
此库的目标是：
它应该拥有很少的依赖性，和禁用单个部分的可能性，当
./configure
.
源和对象两者应该很小。
它应该拥有低 CPU 和内存使用率。
它应该避免几乎没有人需要的无用特征。
