Flutter 颤振视频播放包问题

你好，我尝试了video_playeur软件包，但在我多次重放视频时崩溃。。。报告如下：

我的职能

   Future<String> create_video() async {

SharedPreferences prefs = await SharedPreferences.getInstance();
prefs.setString('daysfromnow_modify',daysfromnow_modify)??"";


final Directory extDir = await getApplicationDocumentsDirectory();
_controller = VideoPlayerController.network(

    'file:${extDir.path}/Movies/$daysfromnow_modify.mp4'

)

..initialize().then((_) {
  setState(() {


      if( _controller!=null){
        _changed(true, "video_chargement"); //display video
      }else{
        _changed(false, "video_chargement"); // hide video
      }

    });

});

Future create_video（）异步{
SharedReferences prefs=等待SharedReferences.getInstance（）；
prefs.setString（'daysfromnow\u modify'，daysfromnow\u modify）；
最终目录extDir=wait getApplicationDocumentsDirectory（）；
_控制器=VideoPlayerController.network(
'文件：${extDir.path}/Movies/$daysfromnow\u modify.mp4'
)
…初始化（）。然后（u41;{
设置状态（）{
如果（_controller！=null）{
_更改（true，“视频收费”）；//显示视频
}否则{
_更改（错误，“视频收费”）；//隐藏视频
}
});
});

} 一切都很好，但在5次重播、8次重播或10次重播后，我随机崩溃了

我使用这个示例，只添加了_controller.initialize（）；若要在没有它的情况下重放视频，我无法重放已完成的视频。但是当controller.initialize（）时；如果（\u controller.value.position>=\u controller.value.duration）{u controller.seekTo（duration.zero），则通过不使用initilized，而是将播放返回到零来实现此解决方案}但我在加载下一个视频时总是遇到ressource问题，因为我不知道如何在不使用.initialize（）的情况下重新加载。是的，我有一个三星s7，你觉得发布它怎么样？如果你有一个小例子，你必须先释放当前的视频/媒体编解码器实例，然后再启动另一个实例。如果其他应用程序正在使用

MediaCodec

，如摄像头应用程序或其他视频播放器，也可能发生此问题。不幸的是，在您启动下一个实例时，无法知道解码器是否已释放。假设您使用的是

曲面

来显示视频，则应在

onSurfaceTextureDistromed

中释放编解码器。您可以通过调用

getMaxSupportedInstances

来检查支持多少个

MediaCodec
