是否有任何LAME C ++ wraper \\控制简化（纯code在Linux上的Mac和Win工作）？ [英] Is there any LAME c++ wraper\simplifier (working on Linux Mac and Win from pure code)?

问题描述

所以我想创建简单的PCM为mp3 C ++项目。我想它使用LAME。我爱LAME，但它是真的biiig。所以我需要某种形式的开源的纯code工作用纯跛脚code的工作流程控制简化。这么说来，我给它与PCM和DEST的文件中。呼叫类似

So I want to create simple pcm to mp3 C++ project. I want it to use LAME. I love LAME but It is realy biiig. so I need some kind of OpenSource working from pure code with pure lame code workflow simplifier. So to say I give it File with PCM and DEST file. Call something like

LameSimple.ToMP3（PCM的，文件与MP3，44100，16，MP3，VBR文件）;

矿石4这样的事 - 5线（例如ofcourse应该存在），我有vhat我需要它要轻，操作简单，powerfool，开源，跨平台

ore such thing in 4 - 5 lines (examples ofcourse should exist) and I have vhat I needed It should be light, simple, powerfool, opensource, crossplatform.

有没有这样的事？！？

推荐答案

拉梅真的不是很难使用，虽然有很多的可选配置功能，如果你需要他们。这需要略多于4-5线连接code文件，但并不多。这里是一个工作的例子我拼凑（只是基本功能，没有错误检查）：

Lame really isn't difficult to use, although there are a lot of optional configuration functions if you need them. It takes slightly more than 4-5 lines to encode a file, but not much more. Here is a working example I knocked together (just the basic functionality, no error checking):

#include <stdio.h>
#include <lame/lame.h>

int main(void)
{
    int read, write;

    FILE *pcm = fopen("file.pcm", "rb");
    FILE *mp3 = fopen("file.mp3", "wb");

    const int PCM_SIZE = 8192;
    const int MP3_SIZE = 8192;

    short int pcm_buffer[PCM_SIZE*2];
    unsigned char mp3_buffer[MP3_SIZE];

    lame_t lame = lame_init();
    lame_set_in_samplerate(lame, 44100);
    lame_set_VBR(lame, vbr_default);
    lame_init_params(lame);

    do {
        read = fread(pcm_buffer, 2*sizeof(short int), PCM_SIZE, pcm);
        if (read == 0)
            write = lame_encode_flush(lame, mp3_buffer, MP3_SIZE);
        else
            write = lame_encode_buffer_interleaved(lame, pcm_buffer, read, mp3_buffer, MP3_SIZE);
        fwrite(mp3_buffer, write, 1, mp3);
    } while (read != 0);

    lame_close(lame);
    fclose(mp3);
    fclose(pcm);

    return 0;
}
