德code的MP3到整数流 [英] decode an mp3 to a stream of ints

问题描述

我在寻找一个易于使用的lib，将MP3文件转换成int类型的序列（和反向），preferable，而无需将它们全部倾倒到RAM中。 去code下一16kB的这个缓冲区之类的API将是理想的。

I'm looking for an easy to use lib that will convert an MP3 file to a sequence of int values (and the reverse), preferable without having to dump them all into RAM. A "decode the next 16kB into this buffer" like API would be ideal.

我需要C或简单的C ++绑定。

I need C or simple C++ bindings.

一个MP3＆LT; - > RAW过滤CLI工具的工作，但我宁愿没有要保存在磁盘uncom pressed文件

A MP3<->RAW filter CLI tool would work but I'd rather not have to keep uncompressed files on disk.

推荐答案

尝试 的libmad 或FFmpeg的 libav codeC 。这两个应该满足你的要求。古 mp3lib 它最初是由/一部分得到的（？） mpg123的也已在<$ C $复活C>的mplayer 有了新的发展，也许有最好的表现，但可能是最丑陋的code。 ： - ）

Try libmad or ffmpeg's libavcodec. Both should meet your requirements. The ancient mp3lib which was originally derived from/part of (?) mpg123 has also been resurrected in mplayer with new development and perhaps has the best performance, but probably the ugliest code. :-)
