Example 1 with C

use of androidx.media3.common.C in project media by androidx.

the class ServerSideAdInsertionMediaSource method setAdPlaybackStates.

/**
 * Sets the map of {@link AdPlaybackState ad playback states} published by this source. The key is
 * the period UID of a period in the {@link
 * AdPlaybackStateUpdater#onAdPlaybackStateUpdateRequested(Timeline)} content timeline}.
 *
 * <p>Each period has an {@link AdPlaybackState} that tells where in the period the ad groups
 * start and end. Must only contain server-side inserted ad groups. The number of ad groups and
 * the number of ads within an ad group may only increase. The durations of ads may change and the
 * positions of future ad groups may change. Post-roll ad groups with {@link C#TIME_END_OF_SOURCE}
 * must be empty and can be used as a placeholder for a future ad group.
 *
 * <p>May be called from any thread.
 *
 * @param adPlaybackStates The map of {@link AdPlaybackState} keyed by their period UID.
