  You could retrieve the reference to the muxer by recursively searching
in encodebin (through gst_bin_iterate_elements()) for an element whose
factory klass contains 'Muxer' *or* that implements the GstTagSetter
interface.

  Ideally we should make encodebin implement the TagSetter interface
(and proxy the various calls to the contained compatible elements).
