Handling the ghostpad and its internal pad was causing more issues than helping because of their coupled activation/deactivation actions. As we have to install custom chain,event and query functions it is better to use a floating sink pad internally in the demuxer and just use those pad functions to push through a standard pad in the demuxer https://bugzilla.gnome.org/show_bug.cgi?id=757951
