Example 2 with SingleSampleMediaChunk

use of androidx.media3.exoplayer.source.chunk.SingleSampleMediaChunk in project media by androidx.

the class FakeChunkSource method getNextChunk.

    long bufferedDurationUs = loadPositionUs - playbackPositionUs;
    int chunkIndex = queue.isEmpty() ? dataSet.getChunkIndexByPosition(playbackPositionUs) : (int) queue.get(queue.size() - 1).getNextChunkIndex();
    MediaChunkIterator[] chunkIterators = new MediaChunkIterator[trackSelection.length()];
