Description Sebastien Cote 2006-06-20 23:01:31 UTC 
I'm parsing a pipeline file created by GstXml to create a graphical image of the pipeline. But the XML file doesn't contain any information about the direction of the pads. This information would be very helpful since it conveys information about the data flow.

proposed fix

With this patch, the direction of the pad is added to the pad structure of the XML file:

  <gst:pad>
    <gst:name>src</gst:name>
    <gst:direction>source</gst:direction>
    <gst:peer>videoflip0.sink</gst:peer>
  </gst:pad>

This image shows the image generated by parsing the XML file. Without the pad direction, there are no arrowheads so the data flow is harder to figure out.
