wav格式音频转换成aac格式音频(三)

根据前面两篇的分析，已经写好了所需要的相关函数，因而最后一篇就只剩下写个main.cpp函数，调用这些函数，如下：

#include"AACCodecHelper.h"

#include<stdio.h>
extern int nPCMBufferSize;
int main(int argc,char* argv[]){
   FILE* fpIn;
   FILE* fpOut;
   fpIn = fopen(argv[1], "rb");
   fpOut = fopen(argv[2], "wb");
   char wav[1000 * 1024];
   char aac[1000 * 1024];
   char* wavData = wav;
   char* aacData = aac;
   INT32 readWavByteMaxLength = 2048;
   INT32 nBytesReadTemp = 0;
   INT32 writeAACByteSum = 0;
    INT32 nReadWavBytes = 0;
   INT32 j = 0;
   INT32 k = 0;
   INT32 i = 0;
   BYTE* pbPCMBufferTemp = new BYTE[readWavByteMaxLength];
    openFaacEngine();//打开Faac引擎
   for (i = 0; 1; i++) {
       nReadWavBytes = fread(pbPCMBufferTemp, 1, nPCMBufferSize, fpIn);
       for(j=0;j<nPCMBufferSize;j++){
           *(wavData + j) = *(pbPCMBufferTemp + j);
       }
       writeAACByteSum = wavToAAC(wavData,nPCMBufferSize,aacData);//调用编码函数
       fwrite(aac, 1, writeAACByteSum, fpOut);
       fflush(fpOut);
       if (nReadWavBytes <= 0) {
           break;
       }
   }
    closeFaacEngine();//关闭Faac引擎

}

未完待续~
