Hello!

And I just wanted to ask whether ExoPlayer does automatically switch to the most appropriate track (bitrate) in HLS stream.

Yes, it does.

Do these rows respond for auto switching? Is DefaultTrackSelector the class which is reponsible?

        TrackSelection.Factory videoTrackSelectionFactory = new AdaptiveVideoTrackSelection.Factory(BANDWIDTH_METER);
        trackSelector = new DefaultTrackSelector(mainHandler, videoTrackSelectionFactory);
        trackSelector.addListener(this);
        trackSelector.addListener(eventLogger);
        player = ExoPlayerFactory.newSimpleInstance(this, trackSelector, new DefaultLoadControl());

Should I call any special method for enabling auto switching?

[ojw28]

The TrackSelector creates track selections. For the adaptive video case the selections are produced by the AdaptiveVideoTrackSelection.Factory in the code above. As long as you have similar code to the code in the demo app (and above), it will be enabled by default.

Hi AlirezaGhanbarinia,
Were you able to figure out a way to always start with the lowest bitrate?
If so please can you share the same.

Thanks,

You can use
TrackSelection.Factory videoTrackSelectionFactory = new AdaptiveVideoTrackSelection.Factory Factory(BandwidthMeter bandwidthMeter, int maxInitialBitrate, int minDurationForQualityIncreaseMs, int maxDurationForQualityDecreaseMs, int minDurationToRetainAfterDiscardMs, float bandwidthFraction)
and set the maxInitialBitrate value
