[REQUIRED] Question

I'm trying to get audio tracks from hls strea but getting only one.

Using 'com.google.android.exoplayer:exoplayer:2.12.1'

My play code looks like this

rf.setExtensionRendererMode(DefaultRenderersFactory.EXTENSION_RENDERER_MODE_PREFER);
trackSelector = new DefaultTrackSelector(this);

exoPlayer = new SimpleExoPlayer.Builder(this, rf).setTrackSelector(trackSelector).build();
exoPlayer.addAnalyticsListener(new EventLogger(trackSelector));

playerView.setPlayer(null);
playerView.setPlayer(exoPlayer);
playerView.setUseController(false);

MediaItem mediaItem = new MediaItem.Builder().setUri(mCurrentURL).setMimeType(MimeTypes.APPLICATION_M3U8).build();

exoPlayer.setPlayWhenReady(true);

DataSource.Factory dataSourceFactory = new DefaultHttpDataSourceFactory();
HlsMediaSource hlsMediaSource = new HlsMediaSource.Factory(dataSourceFactory).setAllowChunklessPreparation(true).createMediaSource(mediaItem);

exoPlayer.setMediaSource(hlsMediaSource);
exoPlayer.prepare();

exoPlayer.addAnalyticsListener(new EventLogger(trackSelector)) throw this

I don't know or this is a bug or it's just my code problems, but I can't get audio tracks... I tried ask in StackOverflow, but noone helped -_-

Could you provide us with the media file/link that you are testing with?

I can't give link, because it's depend on ip, maybe if you can send me IP and I can set it for you. I can only attach file I get from urls.

Might be related to or fixed by the fix coming for this bug issue #7877

[Psychical]

If I understood correctly it's happening when tracks is for the same language? I have changed tracks languages, but it's still the same. So I will wait for #7877 bug fix and try again.

I cannot unzip the file you uploaded on my Mac, or is it a zip file at all?

[Psychical]

Sorry, my fault. Fixed.

The media plays well for me on ExoPlayer, including the audio tracks. Are you saying that your device is not playing the audio track?

According to your log, the ffmpeg audio renderer should be playing it:

FfmpegAudioRenderer [
    Group:0, adaptive_supported=N/A [
        [X] Track:0, id=1/15, mimeType=audio/mp4a-latm, codecs=mp4a.40.2, channels=2, sample_rate=48000, supported=YES
    ]
]

Have you tried playing your content on the ExoPlayer demo app?

I see only 1 track, then I need to see at least 2... That's the problem. As you show it's just 1 track, but in my sample it have to be 2 tracks.

ExoPlayer doesn't currently support multiple multiplexed audio tracks in HLS. Adding support for that is tracked by #2014. If you do some research starting from #2014 and going into other issues that reference it, you will find people customizing ExoPlayer to make it work, but it will require some research on your side.
