Android 视频播放器加载缓慢

因此，我正在为ExoPlayer使用自定义控制器布局，如果

DefaultTimeBar

的搜索时间为00:01，而我转到00:03，则会有3或4秒的时间 延迟。我试图播放的视频在我的SD卡中

视频大小为813kb，mp4

我需要增加缓冲区段大小还是需要自定义加载控件

玩家：

自定义控制器的xml：

如何修复延迟？

检查以下内容：

如果您查看答案，您可以找到最小化缓冲时间的方法：

//Minimum Video you want to buffer while Playing
private int MIN_BUFFER_DURATION = 2000;
//Max Video you want to buffer during PlayBack
private int MAX_BUFFER_DURATION = 5000;
//Min Video you want to buffer before start Playing it
private int MIN_PLAYBACK_START_BUFFER = 1500;
//Min video You want to buffer when user resumes video
private int MIN_PLAYBACK_RESUME_BUFFER = 2000;

LoadControl loadControl = new DefaultLoadControl.Builder()
    .setAllocator(new DefaultAllocator(true, 16))
    .setBufferDurationsMs(MIN_BUFFER_DURATION,
         MAX_BUFFER_DURATION,
         MIN_PLAYBACK_START_BUFFER,
         MIN_PLAYBACK_RESUME_BUFFER)
    .setTargetBufferBytes(-1)
    .setPrioritizeTimeOverSizeThresholds(true).createDefaultLoadControl();

TrackSelector trackSelector = new DefaultTrackSelector();
player = ExoPlayerFactory.newSimpleInstance(this, trackSelector, loadControl);

我确实试过了，但是延迟仍然存在@纳扎里尔莫申斯基也尝试过，但拖延仍然存在@纳扎里尔莫申斯基
