我正在尝试使用MediaPlayer类显示视频。 codeProject我正在看一个例子。
public partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();
MediaTimeline timeline =
new MediaTimeline(new Uri("airplane.mpg", UriKind.Relative));
timeline.RepeatBehavior = RepeatBehavior.Forever;
MediaClock clock = timeline.CreateClock();
MediaPlayer player = new MediaPlayer();
player.Clock = clock;
VideoDrawing drawing = new VideoDrawing();
drawing.Rect = new Rect(0, 0, 300, 200);
drawing.Player = player;
DrawingBrush brush = new DrawingBrush(drawing);
this.Background = brush;
}
}
一切都很好,但我不知道如何延长视频。除了使用视图,有谁知道如何使用System.Windows.Media.Stretch来更改视频大小?
(请不要建议使用MediaElement或WpfMediakit或其他类或外部库,此问题专门针对System.Windows.Media.MediaPlayer)。
答案 0 :(得分:0)
好的,我很笨,实际上很容易,
drawing.Rect = new Rect(0, 0, player.NaturalVideoWidth , player.NaturalVideoHeight );
brush.Stretch = System.Windows.Media.Stretch.SomeStretchEnum
