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 128-bit 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)
