Examples with Parameters com.google.android.exoplayer2.trackselection.DefaultTrackSelector.Parameters used on opensource projects

Example 1 with Parameters

use of com.google.android.exoplayer2.trackselection.DefaultTrackSelector.Parameters in project ExoPlayer by google.

the class SimpleExoPlayer method setPlaybackParams.

/**
   * Sets the {@link PlaybackParams} governing audio playback.
   *

        // parameters without failure. We do the same up front, which is redundant except that it
        // ensures an immediate call to getPlaybackParams will retrieve the instance with defaults
        // allowed, rather than this change becoming visible sometime later once the audio renderers
        // receive the parameters.
