/*
**** Background
*
* This implements a way to send and receive event for an object (which can be
* a simple C struct or less).
*
* This is in direct concurrency with the Variable based Callback
* (see src/misc/variables.c).
*
* It has the following advantages over Variable based Callback:
* - No need to implement the whole VLC_COMMON_MEMBERS in the object,
* thus it reduce it size. This is especially true for input_item_t which
* doesn't have VLC_COMMON_MEMBERS. This is the first reason of existence of
* this implementation.
* - Libvlc can easily be based upon that.
* - Existing event are clearly declared (in include/vlc_events.h)
*
*
**** Example usage
*
* (vlc_cool_object_t doesn't need to have the VLC_COMMON_MEMBERS.)
*
* struct vlc_cool_object_t
* {
* ...
* vlc_event_manager_t p_event_manager;
* ...
* }
*
* vlc_my_cool_object_new()
* {
* ...
* vlc_event_manager_init( &p_self->p_event_manager, p_self, p_a_libvlc_object );
* vlc_event_manager_register_event_type(p_self->p_event_manager,
* vlc_MyCoolObjectDidSomething, p_e)
* ...
* }
*
* vlc_my_cool_object_release()
* {
* ...
* vlc_event_manager_fini( &p_self->p_event_manager );
* ...
* }
*
* vlc_my_cool_object_do_something()
* {
* ...
* vlc_event_t event;
* event.type = vlc_MyCoolObjectDidSomething;

/**
* \file
* This file contain structures and function prototypes related
* to the playlist in vlc
*
* \defgroup vlc_playlist Playlist
*
* The VLC playlist system has a tree structure. This allows advanced
* categorization, like for SAP streams (which are grouped by "sap groups").
*
* The base structure for all playlist operations is the input_item_t. This
* contains all information needed to play a stream and get info, ie, mostly,
* mrl and metadata. This structure contains a unique i_id field. ids are
* not recycled when an item is destroyed.
*
* Input items are not used directly, but through playlist items.
* The playlist items are themselves in a tree structure. They only contain
* a link to the input item, a unique id and a few flags. the playlist
* item id is NOT the same as the input item id.
* Several playlist items can be attached to a single input item. The input
* item is refcounted and is automatically destroyed when it is not used
* anymore.
*
* The top-level items are the main media sources and include:
* playlist, media library, SAP, Shoutcast, devices, ...
*
* It is envisioned that a third tree will appear: VLM, but it's not done yet
*
* The playlist also stores, for utility purposes, an array of all input
* items, an array of all playlist items and an array of all playlist items
* and nodes (both are represented by the same structure).
*
* So, here is an example:
* \verbatim
* Inputs array
* - input 1 -> name = foo 1 uri = ...
* - input 2 -> name = foo 2 uri = ...
*
* Playlist items tree
* - playlist (id 1)
* - category 1 (id 2)
* - foo 2 (id 6 - input 2)
* - media library (id 2)
* - foo 1 (id 5 - input 1)
* \endverbatim
*
* Sometimes, an item creates subitems. This happens for the directory access
* for example. In that case, if the item is under the "playlist" top-level item
* and playlist is configured to be flat then the item will be deleted and
* replaced with new subitems. If the item is under another top-level item, it
* will be transformed to a node and removed from the list of all items without
* nodes.
*
* For "standard" item addition, you can use playlist_Add, playlist_AddExt
* (more options) or playlist_AddInput if you already created your input
* item. This will add the item at the root of "Playlist" or of "Media library"
* in each of the two trees.
*
* You can create nodes with playlist_NodeCreate and can create items from
* existing input items to be placed under any node with playlist_NodeAddInput.
*
* To delete an item, use playlist_DeleteFromInput( p_item ) which will
* remove all occurrences of the input.
*
*
* The playlist defines the following event variables:
*
* - "item-change": It will contain the input_item_t->i_id of a changed input
* item monitored by the playlist.
* item being played.
*
* - "playlist-item-append": It will contain a pointer to a playlist_add_t.
* - "playlist-item-deleted": It will contain the playlist_item_t->i_id of a
* deleted playlist_item_t.
*
* - "leaf-to-parent": It will contain the playlist_item_t->i_id of an item that is transformed
* into a node.
*
* The playlist contains rate-variable which is propagated to current input if available
* also rate-slower/rate-faster is in use
*
* XXX Be really carefull, playlist_item_t->i_id and input_item_t->i_id are not
* the same. Yes, the situation is pretty bad.
