Longer description + * + * 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. + * + * 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, ... + * + * 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 = ... + * + * 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) + * - 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. + * + * 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) + * + * Generally speaking, playlist_NodeAddInput should not be used in newer code, it + * will maybe become useful again when we merge VLM; + * + * To delete an item, use playlist_DeleteFromInput( input_id ) which will + * remove all occurrences of the input in both trees + * * @{ */ -/** - * playlist export helper structure - */ +/** Helper structure to export to file part of the playlist */ struct playlist_export_t { char *psz_filename; @@ -46,23 +128,18 @@ struct playlist_export_t playlist_item_t *p_root; }; -/** - * playlist item / node - * \see playlist_t - */ +/** playlist item / node */ struct playlist_item_t { - input_item_t *p_input; /**< input item descriptor */ - - /* Tree specific fields */ - int i_children; /**< Number of children - -1 if not a node */ + input_item_t *p_input; /**< Linked input item */ + /** Number of children, -1 if not a node */ + int i_children; playlist_item_t **pp_children; /**< Children nodes/items */ playlist_item_t *p_parent; /**< Item parent */ int i_id; /**< Playlist item specific id */ - uint8_t i_flags; /**< Flags */ + playlist_t *p_playlist; /**< Parent playlist */ }; #define PLAYLIST_SAVE_FLAG 0x0001 /**< Must it be saved */ @@ -71,80 +148,60 @@ struct playlist_item_t #define PLAYLIST_RO_FLAG 0x0008 /**< Write-enabled ? */ #define PLAYLIST_REMOVE_FLAG 0x0010 /**< Remove this item at the end */ #define PLAYLIST_EXPANDED_FLAG 0x0020 /**< Expanded node */ -#define PLAYLIST_PREFCAT_FLAG 0x0040 /**< Prefer category */ -/** - * Playlist status - */ +/** Playlist status */ typedef enum { PLAYLIST_STOPPED,PLAYLIST_RUNNING,PLAYLIST_PAUSED } playlist_status_t; - -struct services_discovery_t -{ - VLC_COMMON_MEMBERS - char *psz_module; - - module_t *p_module; - - services_discovery_sys_t *p_sys; - void (*pf_run) ( services_discovery_t *); -}; - -struct playlist_preparse_t -{ - VLC_COMMON_MEMBERS - vlc_mutex_t lock; - int i_waiting; - input_item_t **pp_waiting; -}; - - /** Structure containing information about the playlist */ struct playlist_t { VLC_COMMON_MEMBERS -/** - \name playlist_t - These members are uniq to playlist_t -*/ -/*@{*/ - int i_enabled; /**< How many items are enabled ? */ - - /* Arrays of items */ - int i_size; /**< total size of the list */ - playlist_item_t ** pp_items; /**< array of pointers to the - * playlist items */ - int i_all_size; /**< size of list of items and nodes */ - playlist_item_t ** pp_all_items; /**< array of pointers to the - * playlist items and nodes */ - int i_input_items; - input_item_t ** pp_input_items; - int i_last_playlist_id; /**< Last id to an item */ - int i_last_input_id ; /**< Last id on an input */ + struct playlist_services_discovery_support_t { + /* the playlist items for category and onelevel */ + playlist_item_t* p_cat; + playlist_item_t* p_one; + services_discovery_t * p_sd; /**< Loaded service discovery modules */ + } ** pp_sds; + int i_sds; /**< Number of service discovery modules */ + + playlist_item_array_t items; /**< Arrays of items */ + playlist_item_array_t all_items; /**< Array of items and nodes */ + playlist_item_array_t items_to_delete; /**< Array of items and nodes to + delete...
