once again, i am sure we had this problem before but i can't seem to find the
right ticket atm
i've got a sink with the following
Pad Templates:
  SINK template: 'sink'
    Availability: Always
    Capabilities:
      audio/x-raw-int
              endianess: 1234

               channels: [ 1, 2 ]
                  width: 32
                  depth: 24
      audio/x-raw-int
              endianess: 1234
                 signed: { true, false }

      audio/mpeg
                 parsed: true
                 framed: true
      audio/x-ac3
                 framed: true
      audio/x-private1-ac3
                 framed: true
      audio/x-dts
                 framed: true
      audio/x-private1-dts
                 framed: true
      audio/x-private1-lpcm
                 framed: true
      audio/x-wma
                 framed: true

still, a gst-launch playbin2 uri=bla.mp3 will result in a pipeline without an
mp3parse element, even though the element is present and recent with a rank of
primary + 1 (257)
same thing is true for e.g. dcaparse
a manually built pipeline like gst-launch filesrc location=bla.mp3 ! id3demux !
dvbaudiosink will not fail to link either, even though pad templates are
incompatible

i'm working with 0.10 branches of core, base, good, bad & ugly from today
