可以用如下方法:

修改AudioYusuStreamOut.cpp,添加方法:

复制代码 代码如下:

void AudioYusuStreamOut::swS2M(const void* buffer, size_t bytes)

{

uint32 Idx_i;

int16 PCM_M;

short* pbuffer=(short*)buffer;

{

//enable software stereo to mono

for(Idx_i = 0; Idx_i<bytes>>1; Idx_i+=2)

{

PCM_M = pbuffer[Idx_i+1];

pbuffer[Idx_i+1]=pbuffer[Idx_i];

pbuffer[Idx_i]=PCM_M;

}

}

}

修改ssize_t AudioYusuStreamOut::write(const void* buffer, size_t bytes)

在dumpPcmData(streamout_ori,outbuffer,bytes,streamout_ori_propty);

之前添加: swS2M(buffer,bytes);
