音视频编解码组件AudioDecoder得到的buffer数据大小和AudioRenderer_OnWriteData回调buffer length不匹配

auto mem=input->memory_; 
auto srcBuffer = mem->GetAddr(); 
auto destBuffer = const_cast<uint8_t *>(srcBuffer)； 
auto srcLength= mem->GetSize(); 
size_t destLength= srcLength; 
while (isForcePaused_ && seekable_ ==Seekable::SEEKABLE) { 
OHOS∷Media∷SleepInJob(5); //5ms 
continue; 
} 
OHOS∷Media::AutoLock lock(renderMutex_); 
FALSE RETURN_V(audioRenderer != nullptr,Status∷ERROR_NULL_POINTER); 
for(;destLength>0;){ 
  ret= audioRenderer_->Write(destBuffer, destLength); 
  if(ret<0){ 
    MEDIA_LOG_E("Write data error ret is:" PUBLIC_LOG_D32，ret ); 
    break; 
  } else if (static_cast<size_t>(ret) < destLength) { 
0HOS::Media::SleepInJob(5); //5ms 
} 
  destBuffer += ret; 
  destLength-=ret; 
  MEDIA_LOG_DD("written data size " PUBLIC_LOG_D32,ret);
