Detailed Description

The QIfMediaIndexerControl controls the media indexer. It provides a way to temporarily pause the indexing and resume it, as well as to inquire about the current state and progress of the indexing operation.

The QIfMediaIndexerControl expects a single backend to be available. It is recommended to use it with discoveryMode set to QIfAbstractFeature::AutoDiscovery.

Uses qtifmedia as configurationId for QIfConfiguration based settings.
