           Summary: vc1parse: select caps according to wmv format at
                    negotiation
    Classification: Platform
           Product: GStreamer
           Version: git
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: gst-plugins-bad
        AssignedTo: gstreamer-bugs at lists.freedesktop.org

My hardware decoder can decode both WMV3 and WVC1, but it request different
header-format/stream-format for each WMV format. So my decoder caps are
basically:
video/x-wmv
                 format: WVC1
          stream-format: bdu
                  width: [ 1, 2147483647 ]
                 height: [ 1, 2147483647 ]
      video/x-wmv
                 format: WMV3
          header-format: sequence-layer-raw-frame
                  width: [ 1, 2147483647 ]
                 height: [ 1, 2147483647 ]

But currently, when we negotiate the output format in vc1parse element, it
keeps the first structure regardless of the format.
