  46  * See also stream_FilterChainNew(). Those two functions have identical
  47  * semantics and ownership rules, except for the use of demux vs stream.

  53  * source input stream, and transfers it to the first demux filter in the
  54  * constructed chain. Any use of the source after the function call is invalid
  55  * and undefined (unless the chain ends up empty).
  56  *
  57  * @return The last demux (filter) in the chain.
  58  * The return value is always a valid (non-NULL) demux pointer.
