Timeout error occurred for capturing an image from photo stream in IMFSourceReaderCallback::OnReadSample?

Question

I'm using source reader technique to take a snap from photo stream from the USB camera device. Inconsistently I'm getting a timeout error(ERROR_TIMEOUT). Moreover, IMFSample contains NULL value and dwStreamFlags parameter returns MF_SOURCE_READERF_ERROR if above issue occurred.

Using below code to trigger the still:

   hr = pAttribute->SetUINT32(MF_DEVICESTREAM_TAKEPHOTO_TRIGGER,1L);
   if(FAILED(hr)){  goto done;}

   // Ask for the still sample. '1' is PhotoStream index.
   hr = m_pReader->ReadSample(1,0,NULL,NULL,NULL,NULL);
   if(FAILED(hr)) { goto done;}

This code is working for most of the resolution.

Past 2 weeks I was struggling with this issue. Am I doing anything wrong? Could you please give me an idea/guidelines to sort out this issue?

Thank in advance.
