Example 5 with TrackGroupArray

use of com.google.android.exoplayer2.source.TrackGroupArray in project ExoPlayer by google.

the class HlsSampleStreamWrapper method buildTracks.

/**
   * Builds tracks that are exposed by this {@link HlsSampleStreamWrapper} instance, as well as
   * internal data-structures required for operation.
   * <p>
   * Tracks in HLS are complicated. A HLS master playlist contains a number of "variants". Each
   * variant stream typically contains muxed video, audio and (possibly) additional audio, metadata
   * and caption tracks. We wish to allow the user to select between an adaptive track that spans
   * all variants, as well as each individual variant. If multiple audio tracks are present within
   * each variant then we wish to allow the user to select between those also.
   * <p>
   * To do this, tracks are constructed as follows. The {@link HlsChunkSource} exposes (N+1) tracks,
   * where N is the number of variants defined in the HLS master playlist. These consist of one
   * adaptive track defined to span all variants and a track for each individual variant. The
   * adaptive track is initially selected. The extractor is then prepared to discover the tracks
   * inside of each variant stream. The two sets of tracks are then combined by this method to
   * create a third set, which is the set exposed by this {@link HlsSampleStreamWrapper}:
   * <ul>
   * <li>The extractor tracks are inspected to infer a "primary" track type. If a video track is
   * present then it is always the primary type. If not, audio is the primary type if present.
   * Else text is the primary type if present. Else there is no primary type.</li>
   * <li>If there is exactly one extractor track of the primary type, it's expanded into (N+1)
   * exposed tracks, all of which correspond to the primary extractor track and each of which
   * corresponds to a different chunk source track. Selecting one of these tracks has the effect
   * of switching the selected track on the chunk source.</li>
   * <li>All other extractor tracks are exposed directly. Selecting one of these tracks has the
   * effect of selecting an extractor track, leaving the selected track on the chunk source
   * unchanged.</li>
   * </ul>
