[ERROR:flutter/lib/ui/ui_dart_state.cc(209)] Unhandled Exception: PlatformException(VideoError, Video player had error com.google.android.exoplayer2.ExoPlaybackException: MediaCodecVideoRenderer error, index=0, format=Format(1, null, null, video/avc, avc1.64001F, -1, null, [540, 960, 30.0], [-1, -1]), format_supported=YES, null, null)

有时候只有声音没有画面是怎么回事？

• 大概持续向下刷一段时间，就会出现视频闪一下然后开始播放声音，但是屏幕是黑的。同时失去控制，控制台打印currentplayer的value，状态也不是正在播放。等于完全没有办法控制了，像是漏网一样。

还有加载失败重播应该如何处理比较好？

• 有时候会网络加载失败，我采用的方法是重新填入原来的播放列表，强制刷新...

Actually, I'm showing continuous video player [similar to homePage] on upper layer (means in separate screen).

I had opened videoplayer and close it, at the dispose time it shows these errors

I'm doing this in dispose method

 @override
  void dispose() {
    WidgetsBinding.instance!.removeObserver(this);
    _videoListController.currentPlayer.pause();
    _videoListController.dispose();
    super.dispose();
  }

the error comes on this line on pause method of the video

 @override
  Future<void> pause({bool showPauseIcon: false}) async {
    await Future.wait(_actLocks);
    _actLocks.clear();
    await init();
    if (!prepared) return;
    if (_disposeLock != null) {
      await _disposeLock?.future;
    }
    await this.controller.pause();
    **------------_showPauseIcon.value = true;------------**
  }
