pcm格式的音频裸数据存储成 .avi 播放不了,求解决

}



//写入PCM数据,
void CMediaController::OnCallBackLocalPCMData(LPBYTE pData,int dLen)
{
if (dLen > 0)
{
if (m_CallBackBuffer_Audio.GetLength() >= m_CallBackBuffer_Audio.GetSize())

AVIStreamWrite(m_aviAudioStream,m_aviAudioFrames++,1,pData,dLen,0,NULL,NULL);
/*CMediaPack* packet = new CMediaPack();
packet->SetRawData(pData, dLen);
int nLen = m_CallBackBuffer_Audio.Put((char *)&packet, sizeof(CMediaPack*));*/
return ;
}
}


以上代码经过测试，播放不了，谁熟悉帮忙指导下

Vc6 msdn 的例子里有叫AVIEDIT的，可以参考下
