本文详细记录了在Live555框架下进行的PCM音频数据转AAC编码的过程，通过二次开发，最终成功实现了编码转换并验证其正确性。

Live555二次开发中的PCM转编码AAC,已调试成功！！！

void Encode_Init( )
{
    faacEncConfigurationPtr myFormat;    
    inputPcmSamples = 0;
    maxOutputPcmBytes = 0;
    readSize = 0;
    out_len = 0;

    g_hEncoder = faacEncOpen(8000, 1, &inputPcmSamples, &maxOutputPcmBytes);
    
    myFormat = faacEncGetCurrentConfiguration(g_hEncoder);

    myFormat->inputFormat = FAAC_INPUT_16BIT;//mark by ycs
    myFormat->outputFormat =1;/*1;*/

    //myFormat->aacObjectType = LOW;
    //myFormat->mpegVersion = MPEG4;
    //myFormat->useLfe = 0;
    //myFormat->quantqual =100;
    //myFormat->bandWidth = 0;
    myFormat->bitRate = 0;
    //myFormat->shortctl = SHORTCTL_NORMAL;
    
    myFormat->allowMidside = 1;
    myFormat->aacObjectType = LOW;
    myFormat->mpegVersion = MPEG4;
    myFormat->useTns = 1;
    myFormat-&
