IltmmCapture::EstimateOutputSize Example for C++

void OutputSizeEstimation(IltmmCapture *pCapture)
{
   double Size;

   // start capture
   pCapture->StartCapture(ltmmCapture_Mode_VideoAndAudio);

   // After starting capture, get the expected output size for a capture of 5 seconds
   pCapture->EstimateOutputSize(5.0, &Size);
   // do something with the returned value.
