使用Microsoft表达式编码器自定义捕获大小

Question

我有我能够记录屏幕的C＃代码行。但是我找不到解决方法来确定自定义视频输出大小。我的屏幕分辨率是1920x1080，尽管我尝试为记录分配新的大小，但它保持不变。（库：Microsoft表达式编码器，包括所有依赖关系）

我在按钮单击事件中使用的代码：

        ScreenCaptureJob _screenCaptureJob = new ScreenCaptureJob();
        Rectangle _screenRectangle = Screen.PrimaryScreen.Bounds;
        _screenCaptureJob.CaptureRectangle = _screenRectangle;
        _screenCaptureJob.ScreenCaptureVideoProfile.Size = new Size(600, 400); //By doing this Is it supposed to resize original size to 600x400 pixels?
        _screenCaptureJob.ScreenCaptureVideoProfile.AutoFit = true;
        _screenCaptureJob.ShowFlashingBoundary = false;
        _screenCaptureJob.ScreenCaptureVideoProfile.FrameRate = 20;
        _screenCaptureJob.CaptureMouseCursor = true;
        _screenCaptureJob.ScreenCaptureVideoProfile.SmoothStreaming = true;
        _screenCaptureJob.ScreenCaptureVideoProfile.Quality = 20;
        _screenCaptureJob.OutputScreenCaptureFileName = string.Format(@"C:test.wmv");
        if (File.Exists(_screenCaptureJob.OutputScreenCaptureFileName))
        {
            File.Delete(_screenCaptureJob.OutputScreenCaptureFileName);
        }
        _screenCaptureJob.Start();

预先感谢！

您需要做的是将_screenrectangle设置为自定义尺寸：

_screenCaptureJob.CaptureRectangle = new Rectangle(0, 0, 600, 400);

屏幕记录大小可以无分配。
