   [DirectShow] Can't find pins
  Morning all!  I'm trying to figure out why there aren't any pins showing up in some filters I'm creating.  I am trying to use the WMAudio Decoder DMO and WMVideo Decoder DMO filters to be attached to my source filter.  Unfortunately, when I load in my graph to GraphEditPlus, it displays the two DMO filters as not having any pins!Here's a snippet of how I'm implementing it currently (which was actually taken from GraphEditPlus):// add WMVideo Decoder DMOCComPtr<IBaseFilter> pWMVideoDecoderDMO;hr = pWMVideoDecoderDMO.CoCreateInstance(CLSID_WMVideoDecoderDMO);if(FAILED(hr))return E_FAIL;hr = m_pGraphBuilder->AddFilter(pWMVideoDecoderDMO, L"WMVideo Decoder DMO");if(FAILED(hr))return E_FAIL;Later on when I try to connect the pin from my source filter to my video decoder is where I get my error, stating that it can't find the "in0" pin that I'm searching for.UPDATE: Issue is solved!  I needed to put the DMO's in a DMO Wrapper Filter and then initialize that to the type of DMO I wanted to use.[Edited by - DavidNeal on June 4, 2010 11:26:33 AM]
