android - Exoplayer 无法仅播放 HLS 音频

Question

我只有音频链接 https://storage.googleapis.com/as-piepme/1465/livestream/1465.fef238cdc9d9eb0b958d4eb23080e28b/index.m3u8但是Exoplayer无法播放上面的链接， 它返回“源错误”。但IOS和Chrome都运行良好。我的代码:

SimpleExoPlayer player = new SimpleExoPlayer.Builder(context).build();
player.setMediaItem(MediaItem.fromUri(Uri.parse(linkPlay)));
player.prepare();
player.setPlayWhenReady(true);

更新我的解决方案:

MediaItem mediaItem = new MediaItem.Builder()
                        .setUri(Uri.parse("https://storage.googleapis.com/as-piepme/1465/livestream/1465.fef238cdc9d9eb0b958d4eb23080e28b/index.m3u8"))
                        .build();
                DefaultHlsExtractorFactory defaultHlsExtractorFactory = new DefaultHlsExtractorFactory(DefaultTsPayloadReaderFactory.FLAG_IGNORE_H264_STREAM, false);
                MediaSource mediaSource = new HlsMediaSource.Factory(new DefaultHlsDataSourceFactory(new DefaultDataSourceFactory(context)))
                        .setExtractorFactory(defaultHlsExtractorFactory)
                        .setAllowChunklessPreparation(true)
                        .createMediaSource(mediaItem);
                player.setMediaSource(mediaSource);

您需要使用媒体源。

尝试这个示例代码。

DataSource.Factory dataSourceFactory = new DefaultHttpDataSourceFactory();
// Create a HLS media source pointing to a playlist uri.
HlsMediaSource hlsMediaSource =
    new HlsMediaSource.Factory(dataSourceFactory)
        .createMediaSource(MediaItem.fromUri(hlsUri));
// Create a player instance.
SimpleExoPlayer player = new SimpleExoPlayer.Builder(context).build();
// Set the media source to be played.
player.setMediaSource(hlsMediaSource);
// Prepare the player.
player.prepare();

更新 使用这个。

        DefaultTrackSelector trackSelector = new DefaultTrackSelector(this, new AdaptiveTrackSelection.Factory());
        DefaultTrackSelector.Parameters trackSelectorParameters = trackSelector.buildUponParameters().setMaxAudioChannelCount(0).build();
        trackSelector.setParameters(trackSelectorParameters);
        RenderersFactory renderersFactory = new DefaultRenderersFactory(this);
        SimpleExoPlayer audioPlayer = = new SimpleExoPlayer.Builder(this, renderersFactory).setTrackSelector(trackSelector).build();
        HttpDataSource.Factory factory = new DefaultHttpDataSourceFactory("Online Audio Player", DefaultHttpDataSource.DEFAULT_CONNECT_TIMEOUT_MILLIS, DefaultHttpDataSource.DEFAULT_READ_TIMEOUT_MILLIS, true);
        audioPlayer.setMediaSource(new ProgressiveMediaSource.Factory(factory).createMediaSource(MediaItem.fromUri("https://storage.googleapis.com/as-piepme/1465/livestream/1465.fef238cdc9d9eb0b958d4eb23080e28b/index.m3u8")));
        audioPlayer.prepare();
        audioPlayer.setPlayWhenReady(true);
