Question

我创建了一个播放视频的小部件，并在contoroler中放置了视频文件和视频网络，但是播放3个视频时出现此错误

hint: [{
          match: /:([\-+\w]+)$/,
          search: function (keyword, callback) {
            callback($.grep(emojis, function (item) {
              return item.indexOf(keyword)  === 0;
            }));
          },
          template: function (item) {
            var content = emojiUrls[item];
            return '<img src="' + content + '" width="20" /> :' + item + ':';
          },
          content: function (item) {
            var url = emojiUrls[item];
            if (url) {
              return $('<img />').attr('src', url).css('width', 20)[0];
            }
            return '';
          }
        },
        {
            mentions: ['jayden', 'sam', 'alvin', 'david'],
            match: /\B@(\w*)$/,
            search: function (keyword, callback) {
              callback($.grep(this.mentions, function (item) {
                return item.indexOf(keyword) == 0;
              }));
            },
            content: function (item) {
              return '@' + item;
            }    
          }]

这是我在其他页面中使用它的小部件

如何解决此错误，我在三个视频尝试后将视频文件和视频网络分配给它，我如何正确使用处理方法呢？播放了三个视频，但我最多使用chewie软件包

Answer 1

有点晚了，但这是解决方案。我拉了很多毛，终于得出结论。

“ pub.dev”中的“ video_player”库无法按预期管理资源。

如果在不处置控制器本身的情况下初始化新视频，则它会分配新资源，并且如果继续初始化3个以上视频，则手机的平台特定播放器（在这种情况下，“ exoplayer2”无法注销正确的错误消息）

确保每次播放不同的视频时都已处置控制器并创建了新控制器。

编辑：

Future<void> playVideo() async{
    VideoPlayerController _old = videoPlayerController;
    if(mounted)
      setState(() {
        videoPlayerController = null;
      });
    videoPlayerController = VideoPlayerController.file(widget.videoFiles[itemIndex]);
    await videoPlayerController.initialize();
    if(mounted)
      setState(() {duration = videoPlayerController.value.duration;});
    await videoPlayerController.play();
    Future.delayed(Duration(seconds: 1),(){
      _old?.dispose();
    });
  }

Answer 2

使用低于框架宽度和高度。宽度 1280 和高度 720 我在flutter开发中使用了这帧视频并正确显示。

颤动在视频播放器中不能播放3个以上的视频
