        smart_array<WCHAR>awch = new WCHAR[wStrLen];
        pStream->GetStreamName(awch, &wStrLen);
        WMFOutputPin *pin = new WMFOutputPin(this, &m_csFilter, &hr, awch);
		LIST_DATA local_stream_data;
		local_stream_data.first = wStream;
		local_stream_data.second = pin;
        // insert in map, using wStream as index
        m_Outputs.push_back(local_stream_data);
        // get the compressed media type from the profile for this stream
