[gst-devel] Question about caps, displayed in .dot files

[wl2776]

While using GST_DEBUG_BIN_TO_DOT_FILE macro I am getting different pictures. 
Sometimes links between elements have two caps definitions, and sometimes -
only one.

For example, when I build a pipeline using gst-launch, typefind and
mpegpsdemux have a link with two labels: 
video/mpeg 
  mpegversion: {1, 2} 
  systemstream: true
video/x-cdxa

at the typefind.source 
and 
ANY 
at mpegpsdemux.sink

However, when I use playbin2, this link has only one label:
video/mpeg 
  mpegversion: {1, 2} 
  systemstream: true


Do two caps labels mean that the linked elements are not fully negotiated
yet?
