Video tracks selection¶

Keeping track of tracks¶

The current PlaybackSession manages available and selected audio/subtitle tracks.

public interface IPlaybackSession {
    ...
    List<IVideoTrack> getVideoTracks();
    IVideoTrack getSelectedVideoTrack();
    ...
}

The IPlaybackSessionListener interface also contains events for when these values change.

public interface IPlaybackSessionListener {
    ...
    void onVideoTracks(List<IVideoTrack> tracks);
    void onSelectedVideoTrackChanged(IVideoTrack oldSelectedTrack, IVideoTrack newSelectedTrack);
    ...
}

These events can be used to initiate and update UI elements.

Note¶

onVideoTracks(...) can get called at any time. This is dependent on the current stream and the playerImplementation.

Example - Video track¶

Changing selected video track¶

Video track selection can be Adaptive or Fixed:

Adaptive video track selection: use following API and SDK to optimize the video track selection based on network conditions

public void selectVideoTrack(IVideoTrack audioTrack) {
        enigmaPlayer.getControls().setMaxVideoTrackDimensions(object);
}

The following API can be used to force the selected video track:

public void selectVideoTrack(IVideoTrack audioTrack) {
        enigmaPlayer.getControls().setVideoTrack(object);
}

It will toggle between adaptive strategy and fixed video track and vice-versa.
