the class HlsMediaPeriod method buildAndPrepareMainSampleStreamWrapper.

/**
 * This method creates and starts preparation of the main {@link HlsSampleStreamWrapper}.
 *
 * <p>The main sample stream wrapper is the first element of {@link #sampleStreamWrappers}. It
 * provides {@link SampleStream}s for the variant urls in the multivariant playlist. It may be
 * adaptive and may contain multiple muxed tracks.
 *
 * <p>If chunkless preparation is allowed, the media period will try preparation without segment
 * downloads. This is only possible if variants contain the CODECS attribute. If not, traditional
 * preparation with segment downloads will take place. The following points apply to chunkless
 * preparation:
 *
 * <ul>
 *   <li>A muxed audio track will be exposed if the codecs list contain an audio entry and the
 *       multivariant playlist either contains an EXT-X-MEDIA tag without the URI attribute or
 *       does not contain any EXT-X-MEDIA tag.
 *   <li>Closed captions will only be exposed if they are declared by the multivariant playlist.
 *   <li>An ID3 track is exposed preemptively, in case the segments contain an ID3 track.
 * </ul>
 *
 * @param multivariantPlaylist The HLS multivariant playlist.
 * @param positionUs If preparation requires any chunk downloads, the position in microseconds at
 *     which downloading should start. Ignored otherwise.
 * @param sampleStreamWrappers List to which the built main sample stream wrapper should be added.
 * @param manifestUrlIndicesPerWrapper List to which the selected variant indices should be added.
 * @param overridingDrmInitData Overriding {@link DrmInitData}, keyed by protection scheme type
 *     (i.e. {@link DrmInitData#schemeType}).
