示例1: buildRenderers
import com.google.android.exoplayer.upstream.FileDataSource; //导入依赖的package包/类
@Override
public void buildRenderers(ExoPlayerHelper player) {
Allocator allocator = new DefaultAllocator(BUFFER_SEGMENT_SIZE);
// Build the video and audio renderers.
Extractor webmExtractor = new WebmExtractor();
Extractor mp4Extractor = new Mp4Extractor();
DataSource dataSource = new FileDataSource();
ExtractorSampleSource sampleSource = new ExtractorSampleSource(uri, dataSource, allocator,
BUFFER_SEGMENT_COUNT * BUFFER_SEGMENT_SIZE, webmExtractor, mp4Extractor);
MediaCodecVideoTrackRenderer videoRenderer = new MediaCodecVideoTrackRenderer(context,
sampleSource, MediaCodecSelector.DEFAULT, MediaCodec.VIDEO_SCALING_MODE_SCALE_TO_FIT, 5000, player.getMainHandler(),
player, 50);
MediaCodecAudioTrackRenderer audioRenderer = new MediaCodecAudioTrackRenderer(sampleSource, MediaCodecSelector.DEFAULT,
null, true, player.getMainHandler(), player);
TrackRenderer textRenderer = new TextTrackRenderer(sampleSource, player,
player.getMainHandler().getLooper());
// Invoke the callback.
TrackRenderer[] renderers = new TrackRenderer[ExoPlayerHelper.RENDERER_COUNT];
renderers[ExoPlayerHelper.TYPE_VIDEO] = videoRenderer;
renderers[ExoPlayerHelper.TYPE_AUDIO] = audioRenderer;
