◆ AddAlbumCache()

static void AddAlbumCache ( input_fetcher_t fetcher,
input_item_t item,
bool  overwrite 
)
static

◆ CancelAllTasks()

static void CancelAllTasks ( input_fetcher_t fetcher)

static

◆ CheckMeta()

static int CheckMeta ( input_item_t item)
static

◆ CreateCacheKey()

static char* CreateCacheKey ( input_item_t item)
static

Simple concatenation of artist and album can lead to the same key for entities that should not have such. Imagine { dogs, tick } and { dog, stick }

This function enqueues the provided item to be art fetched.

The input item is retained until the art fetching is done or until the fetcher object is destroyed.
