acces to data stream (KLV) with windows media-foundation

Question

Is there any way to acces data stream with Windows Media Foundation ?

I have a video stream that contains tree streams: Audio, video and Data stream When I opend the file with ffmpeg I can access the three stream:

• AVMEDIA_TYPE_AUDIO
• AVMEDIA_TYPE_VIDEO
• AVMEDIA_TYPE_DATA

This image show more details about the data stream I wanted to retrieve.

With windows media-foundation I can only see audio and video streams.

IMFMediaSource* pVideoSource = NULL;
IMFSourceReader* pVideoReader = NULL;           
....
....
while (pVideoReader->GetStreamSelection(stmIndex, &isSelected) == S_OK) {
      printf("Stream %d is selected %d.\n", stmIndex, isSelected);

      CHECK_HR(pVideoReader->GetCurrentMediaType(stmIndex, &pStmMediaType), "Failed to get media type for selected stream.");

      std::cout << "Media type: " << GetMediaTypeDescription(pStmMediaType) << std::endl;

      GUID majorMediaType;
      pStmMediaType->GetGUID(MF_MT_MAJOR_TYPE, &majorMediaType);
      if (majorMediaType == MFMediaType_Audio) {
          std::cout << "Source audio stream index is " << stmIndex << "." << std::endl;
      }
      else if (majorMediaType == MFMediaType_Video) {
          std::cout << "Video stream index is " << stmIndex << "." << std::endl;
      }
      stmIndex++;
      SAFE_RELEASE(pStmMediaType);
  }

**Output **

I also looked on the sample metadata. I didn't find anything. MFSampleExtension_CaptureMetadata

 HRESULT hr = videoSample->GetUnknown(MFSampleExtension_CaptureMetadata, IID_IMFAttributes, (void**)&pAttributes);

Result

hr = 0xc00d36e6 : The requested attribute was not found. access to data stream with media-foundation
