the class ConcatenatingMediaSourceTest method childSourceIsPreparedWithLazyPreparationAfterPeriodCreation.

@Test
public void childSourceIsPreparedWithLazyPreparationAfterPeriodCreation() throws IOException {

    2);

    0), /* windowSequenceNumber= */
    0));

    assertThat(childSources[1].isPrepared()).isFalse();
}

Example 2 with DefaultShuffleOrder

use of androidx.media3.exoplayer.source.ShuffleOrder.DefaultShuffleOrder in project media by androidx.

the class ConcatenatingMediaSourceTest method removeUnpreparedChildSourceWithLazyPreparation.

@Test
public void removeUnpreparedChildSourceWithLazyPreparation() throws IOException {
    FakeMediaSource[] childSources = createMediaSources(/* count= */
    2);
    mediaSource = new ConcatenatingMediaSource(/* isAtomic= */

    mediaSource.removeMediaSource(0);
}

Example 3 with DefaultShuffleOrder

use of androidx.media3.exoplayer.source.ShuffleOrder.DefaultShuffleOrder in project media by androidx.

the class ConcatenatingMediaSourceTest method childSourceWithLazyPreparationOnlyPreparesSourceOnce.

@Test
public void childSourceWithLazyPreparationOnlyPreparesSourceOnce() throws IOException {
    FakeMediaSource[] childSources = createMediaSources(/* count= */
    2);
    mediaSource = new ConcatenatingMediaSource(/* isAtomic= */

    true, new DefaultShuffleOrder(0), childSources);
    testRunner = new MediaSourceTestRunner(mediaSource, /* allocator= */
    null);
    Timeline timeline = testRunner.prepareSource();
    // The lazy preparation must only be triggered once, even if we create multiple periods from
    // the media source. FakeMediaSource.prepareSource asserts that it's not called twice, so
    // creating two periods shouldn't throw.
    MediaPeriodId mediaPeriodId = new MediaPeriodId(timeline.getUidOfPeriod(/* periodIndex= */
    0), /* windowSequenceNumber= */
    0);
