Provided Methods

unsafe fn metadataCollector_didCollectDateRangeMetadataGroups_indexesOfNewGroups_indexesOfModifiedGroups( &self, metadata_collector: &AVPlayerItemMetadataCollector, metadata_groups: &NSArray<AVDateRangeMetadataGroup>, indexes_of_new_groups: &NSIndexSet, indexes_of_modified_groups: &NSIndexSet, )

where Self: Sized + Message,

Available on crate feature AVTimedMetadataGroup only.

A delegate callback that delivers the total set of AVDateRangeMetadataGroups for this collector.

Parameter metadataCollector: The AVPlayerItemMetadataCollector source.

Parameter metadataGroups: The set of all metadata groups meeting the criteria of the output.

Parameter indexesOfNewGroups: Indexes of metadataGroups added since the last delegate invocation of this method.

Parameter indexesOfModifiedGroups: Indexes of metadataGroups modified since the last delegate invocation of this method.

This method will be invoked whenever new AVDateRangeMetadataGroups are added to metadataGroups or whenever any AVDateRangeMetadataGroups in metadataGroups have been modified since previous invocations. The initial invocation will have indexesOfNewGroup referring to every index in metadataGroups. Subsequent invocations may not contain all previously collected metadata groups if they no longer refer to a region in the AVPlayerItem’s seekableTimeRanges.
