Class
RBMetaData
Description [src]
class RB.MetaData : GObject.Object
{
priv: RBMetaDataPrivate*
}Provides a simple synchronous interface for metadata extraction and updating.
Instance methods
rb_metadata_can_save
Checks if the metadata writer is capable of updating file metadata for a given media type.
rb_metadata_get
Retrieves the value of a metadata field extracted from the target URI. If the target URI contained no value for the field, returns FALSE.
rb_metadata_get_media_type
Returns the type of the file from which metadata was read. This may look like a MIME type, but it isn’t.
rb_metadata_get_missing_plugins
This function returns the information used to request automatic
installation of media framework plugins required to decode the target URI.
Use g_strfreev() to free the returned information arrays.
rb_metadata_get_saveable_types
Constructs a list of the media types for which the metadata backend implements tag saving.
rb_metadata_has_missing_plugins
If the metadata reader could not decode the file it was asked to because one or more media framework plugins (specifically, for the existing implementations, GStreamer plugins) required are missing, this will return TRUE.
rb_metadata_load
Reads metadata information from the specified URI. Once this has returned successfully (with *error == NULL), rb_metadata_get, rb_metadata_get_media_type, rb_metadata_has_missing_plugins, and rb_metadata_get_missing_plugins can usefully be called.
rb_metadata_reset
Resets the state of the metadata interface. Call this before setting tags to be written to a file.
rb_metadata_set
Sets a metadata field value. The value is only stored inside the
RBMetaData object until rb_metadata_save is called.
Signals
Signals inherited from GObject (1)
GObject::notify
The notify signal is emitted on an object when one of its properties has its value set through g_object_set_property(), g_object_set(), et al.
