-/** \brief Playlist class
- *
- * A playlist is a sequential container of producers and blank spaces. The class provides all
- * sorts of playlist assembly and manipulation routines. A playlist is also a producer within
- * the framework.
- *
- * \extends mlt_producer_s
- * \properties \em autoclose Set this true if you are doing sequential processing and want to
- * automatically close producers as they are finished being used to free resources.
- * \properties \em meta.fx_cut Set true on a producer to indicate that it is a "fx_cut,"
- * which is a way to add filters as a playlist entry - useful only in a multitrack. See FxCut on the wiki.
- * \properties \em mix_in
- * \properties \em mix_out
