title: How to debug H264 DirectShow filter?
body: <p>I'm developping a h264 directshow filter.</p>
  
  <p>I have a valid hardware source which outputs NAL units properly.
  I have a DirectShow filter which advertises h264 and successfully connects to the default windows 7 decoder microsoft dtv-dvd video decoder.</p>
  
  <p>When I connect a renderer to the decoder, the renderer doesn't get any packets, so I assume that the decoder fails to decode my packets properly.</p>
  
  <p>[ h264 Source ] -> [ dtv-dvd decoder ] -> [ enhanced video renderer ]</p>
  
  <p>Is there any way for me to check where the microsoft decoder fails?</p>
  
  <p>Any other info could be helpful</p>
