Example 1 with Allocator

use of com.google.android.exoplayer2.upstream.Allocator in project ExoPlayer by google.

the class ConcatenatingMediaSource method createPeriod.

Example 3 with Allocator

use of com.google.android.exoplayer2.upstream.Allocator in project ExoPlayer by google.

the class ConcatenatingMediaSourceTest method childSourceIsNotPreparedWithLazyPreparation.

@Test
public void childSourceIsNotPreparedWithLazyPreparation() throws IOException {
    FakeMediaSource[] childSources = createMediaSources(/* count= */
    2);

    null);
    testRunner.prepareSource();
    assertThat(childSources[0].isPrepared()).isFalse();
    assertThat(childSources[1].isPrepared()).isFalse();
}

Example 4 with Allocator

use of com.google.android.exoplayer2.upstream.Allocator in project ExoPlayer by google.

the class ConcatenatingMediaSourceTest method childSourceWithLazyPreparationOnlyPreparesSourceOnce.

@Test
public void childSourceWithLazyPreparationOnlyPreparesSourceOnce() throws IOException {
    FakeMediaSource[] childSources = createMediaSources(/* count= */
    2);
    mediaSource = new ConcatenatingMediaSource(/* isAtomic= */
    false, /* useLazyPreparation= */
    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);
    testRunner.createPeriod(mediaPeriodId);
    testRunner.createPeriod(mediaPeriodId);
