* item is refcounted and is automatically destroyed when it is not used
* anymore.
*
- * In the playlist itself, there are two trees, that should always be kept
- * in sync. The "category" tree contains the whole tree structure with
- * several levels, while the onelevel tree contains only one level :), ie
- * it only contains "real" items, not nodes
- * For example, if you open a directory, you will have
- *\verbatim
- * Category tree: Onelevel tree:
- * Playlist Playlist
- * - Dir - item1
- * - Subdir - item2
- * - item1
- * - item2
- *\endverbatim
- * The top-level items of both tree are the same, and they are reproduced
- * in the left-part of the playlist GUIs, they are the "sources" from the
- * source selectors. Top-level items include: playlist, media library, SAP,
- * Shoutcast, devices, ...
+ * 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
*
* - input 1 -> name = foo 1 uri = ...
* - input 2 -> name = foo 2 uri = ...
*
- * Category tree Onelevel tree
- * - playlist (id 1) - playlist (id 3)
- * - category 1 (id 2) - foo 2 (id 8 - input 2)
- * - foo 2 (id 6 - input 2) - media library (id 4)
- * - media library (id 2) - foo 1 (id6 - input 1)
+ * 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 must be transformed to a node. This happens for the
- * directory access for example. In that case, the item is removed from
- * the onelevel tree, as it is not a real item anymore.
+ *
+ * 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.
*
- * If you want more control (like, adding the item as the child of a given
- * node in the category tree, use playlist_BothAddInput. You'll have to provide
- * the node in the category tree. The item will be added as a child of
- * this node in the category tree, and as a child of the matching top-level
- * node in the onelevel tree. (Nodes are created with playlist_NodeCreate)
+ * 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:
*
- * Generally speaking, playlist_NodeAddInput should not be used in newer code, it
- * will maybe become useful again when we merge VLM;
+ * - "item-change": It will contain the input_item_t->i_id of a changed input
+ * item monitored by the playlist.
+ * item being played.
*
- * To delete an item, use playlist_DeleteFromInput( input_id ) which will
- * remove all occurrences of the input in both trees
+ * - "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.
