hi
Can anyone help how i can write an avi file using a file writer.

Sourcefitlter ----->AviMux-------> FileWriter

should i have to change any AviMux property or anychanges in source
filter. I am appling time stamp in source filter a follows..

dwPerFrameTime = UNITS / 30; //which gives 333333
HRESULT CTrinityStream::FillBuffer(IMediaSample *pSample)
{

   CAutoLock l(&m_cSharedState);

   HRESULT hr = 0;

    //Copy data from the DVR Buffer ... (This copy should be avoided by
custom allocators (Deepak)
    hr = m_plFilled->RemoveHeadIntoSample(pSample);
    if(FAILED(hr))
    {
        DbgLog((LOG_TRACE, 2, TEXT("RemoveHeadIntoSample() returned %08x;
stopping"), hr));
        return hr;
    }

   // Set the timestamps that will govern playback frame rate.
   // If this file is getting written out as an AVI,
   // then you'll also need to configure the AVI Mux filter to
   // set the Average Time Per Frame for the AVI Header.
   // The current time is the sample's start
   REFERENCE_TIME rtStart = m_lFrameNumber * m_dwPerFrameTime;
   REFERENCE_TIME rtStop  = rtStart + m_dwPerFrameTime;

  //Deepak Experimentally commented ... Let the renderer not wait for
frames based on time.
    //Since we are a capture source
    hr = pSample->SetTime(&rtStart, &rtStop);

   m_lFrameNumber++;

   // Set TRUE on every sample for uncompressed frames
   hr = pSample->SetSyncPoint(TRUE);

    DbgLog((LOG_TRACE,4,TEXT("Frame Time$ start:%ld end:%ld"),
(long)rtStart,(long)rtStop));

   return hr;
}

Can anyone help ...?
