Detailed Description

Provides a interface to control the media indexer

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