Windows8视频选择器

 这个是我在做的win8 项目是遇到的一个大问题，因为刚接触win8，不熟悉win8操作系统

做视频播放中出现 了好多问题， 还有视频与声音的绑定等等， 这是在界面中选取自己笔记本

上有的视频。

private async void SetLocalMedia()
        {
            try
            {
                FileOpenPicker open = new FileOpenPicker();
                open.ViewMode = PickerViewMode.Thumbnail;
                open.FileTypeFilter.Add(".wmv");
                open.FileTypeFilter.Add(".mp4");
                StorageFile file = await open.PickSingleFileAsync();
                var stream = await file.OpenAsync(Windows.Storage.FileAccessMode.Read);
                VideoPlayer.SetSource(stream, file.ContentType);
                VideoPlayer.Play();
                BitmapImage bt = new BitmapImage();
                bt.UriSource = new Uri("ms-appx:///Images/1.png");
                PlayView();
            }
            catch (Exception)
            { }
        }
