A downloader for HLS streams.

Example usage:


 SimpleCache cache = new SimpleCache(downloadFolder, new NoOpCacheEvictor(), databaseProvider);
 CacheDataSource.Factory cacheDataSourceFactory =
     new CacheDataSource.Factory()
         .setCache(cache)
         .setUpstreamDataSourceFactory(new DefaultHttpDataSource.Factory());
 // Create a downloader for the first variant in a multivariant playlist.
 HlsDownloader hlsDownloader =
     new HlsDownloader(
         new MediaItem.Builder()
             .setUri(playlistUri)
             .setStreamKeys(
                 Collections.singletonList(
                     new StreamKey(HlsMultivariantPlaylist.GROUP_INDEX_VARIANT, 0)))
             .build(),
         Collections.singletonList();
 // Perform the download.
 hlsDownloader.download(progressListener);
 // Use the downloaded data for playback.
 HlsMediaSource mediaSource =
     new HlsMediaSource.Factory(cacheDataSourceFactory).createMediaSource(mediaItem);

    Description copied from class: SegmentDownloader
    
    Returns a list of all downloadable SegmentDownloader.Segments for a given manifest. Any required data should be loaded using SegmentDownloader.getManifest(com.google.android.exoplayer2.upstream.DataSource, com.google.android.exoplayer2.upstream.DataSpec, boolean) or SegmentDownloader.execute(com.google.android.exoplayer2.util.RunnableFutureTask<T, ?>, boolean).
    
    Specified by:
    
    getSegments in class SegmentDownloader<HlsPlaylist>
    
    Parameters:
    
    dataSource - The DataSource through which to load any required data.
    
    manifest - The manifest containing the segments.
    
    removing - Whether the segments are being obtained as part of a removal. If true then a partial segment list is returned in the case that a load error prevents all segments from being listed. If false then an IOException will be thrown in this case.
    
    Returns:
    
    The list of downloadable SegmentDownloader.Segments.
    
    Throws:
    
    IOException - Thrown if allowPartialIndex is false and an execution error occurs, or if the media is not in a form that allows for its segments to be listed.
