我正在尝试使用 Firebase 播放视频，但它显示 DefaultHttpDataSourceFactory 已弃用

Question

[我提供了图片链接请看图片我有很多错误1private void initializeExoplayerView(String videoUrl) {

试试{ BandwidthMeter bandwidthMeter = new DefaultBandwidthMeter.Builder(this).build(); TrackSelector trackSelector = new DefaultTrackSelector(this,newAdaptiveTrackSelection.Factory(bandwidthMeter)); exoPlayer = (SimpleExoPlayer) ExoPlayerFactory.newSimpleInstance(this, trackSelector); uri videouri = Uri.parse(videoUrl);

        DefaultHttpDataSourceFactory dataSourceFactory = new DefaultHttpDataSourceFactory("exoplayer_video");
        ExtractorsFactory extractorsFactory = new DefaultExtractorsFactory();
        MediaSource mediaSource = new ExtractorMediaSource(videouri, dataSourceFactory, extractorsFactory, null, null);
        exoPlayerView.setPlayer(exoPlayer);
        exoPlayer.prepare(mediaSource);
        exoPlayer.setPlayWhenReady(true);

    } catch (Exception e){
        Log.e("TAG", "Error : " + e.toString());
    }
}

您应该为 HTTP 数据源使用新的工厂，而不是“DefaultHttpDataSource.Factory”。

您可以在测试和演示代码中的 ExoPlayer GitHub 存储库中找到它的使用示例 - 例如，如果您查看下面的摘录并按照它的调用进行操作：

public void start_playlistCanBlockReloadLowLatencyFullSegment_correctMsnAndPartParams()
      throws IOException, TimeoutException, InterruptedException {
    List<HttpUrl> httpUrls =
        enqueueWebServerResponses(
            new String[] {
              "/master.m3u8",
              "/media0/playlist.m3u8",
              "/media0/playlist.m3u8?_HLS_msn=14&_HLS_part=0"
            },
            getMockResponse(SAMPLE_M3U8_LIVE_MASTER),
            getMockResponse(SAMPLE_M3U8_LIVE_MEDIA_CAN_BLOCK_RELOAD_LOW_LATENCY_FULL_SEGMENT),
            getMockResponse(SAMPLE_M3U8_LIVE_MEDIA_CAN_BLOCK_RELOAD_LOW_LATENCY_FULL_SEGMENT_NEXT));

    List<HlsMediaPlaylist> mediaPlaylists =
        runPlaylistTrackerAndCollectMediaPlaylists(
            new DefaultHttpDataSource.Factory(),
            Uri.parse(mockWebServer.url("/master.m3u8").toString()),
            /* awaitedMediaPlaylistCount= */ 2);
