Question
DirectShow Filter
Hello All,
Im developing a DS Transform Filter which decodes MPEG-2 Video. The decoding part is done and frames are available in uncompressed, raw RGB. Now I need to render them with proper timing and quality.
The Transform function is doing the job
HRESULT CMyFilter::Transform(IMedi
{
HRESULT hr;
// the decoder runs on a separate thread
// the RGB frame is available at member variable 'm_pBuffer'
// m_nWidth and m_nHeight are frame width and height respectively
BYTE* pBufferOut = NULL;
long lSize = m_nWidth*m_nHeight*3;
hr = pDataOut->GetPointer(&pBuf
::CopyMemory(pBufferOut, m_pBuffer, lSize);
pDataOut->SetActualDataLen
}
This will just display the frames as they are decoded and this is not what is expected.
Could any one u advice on what is to be done for proper playback?
or Any pointers which I can use in obtaining the results.
-TIA

In theory, you shouldn't have to worry about the timing, the system should do it for you. Normally, media timings for both IMediaSample have been set before entering the transform method, but you could try to see what's in there in a debugging phase. Use IMediaSample::GetMediaTime
