要更改exoplayer的速度,我们使用player.setPlaybackParameters

这会改变速度,但是我们如何仅在特定持续时间内设置速度

我使用的代码是

playerTimer.setCallback(new PlayerTimer.Callback() {
            @Override
            public void onTick(long timeMillis) {
                if (player != null) {
                    long position = player.getCurrentPosition();
                    long duration = player.getDuration();
                    speeder(position);

                }
            }
        });

public void speeder(long pos) {


        if (player.getCurrentWindowIndex() == 1) {
            if (pos >= 100000) &&
            pos <= 200000){
                PlaybackParameters playbackParameters = new PlaybackParameters(
                        2.0f, 1.0f);
                player.setPlaybackParameters(playbackParameters);
            }
                    else if (pos <= 100000) &&
            pos >= 200000)
            {
                PlaybackParameters playbackParameters1 = new PlaybackParameters(
                        1.0f, 1.0f);
                player.setPlaybackParameters(playbackParameters1);
            }
        }
    }

但是速度在100000到200000之间时不会改变

1 个答案:

答案 0 :(得分:0)

注意:

else if (pos <= 100000) && pos >= 200000) {
   //the value of pos cannot be smaller than 100000 and bigger than 200000 Simultaneously
}

因此条件始终为false
