屏幕記錄單個窗口

Question

我正在尋找一個SDK，插件或代碼，將videorecord特定的窗口（hwnd）。 如果可能的話用C＃或Java。有誰知道這是否存在？我一直在使用Google，但沒有遇到任何問題。

Answer 1

安裝Microsoft Expression Encoder 4 with Service Pack 2 (SP2)。

下面是一個示例程序來使用它。一個更完整的樣本隨SDK提供，包含在下載中。

using System; 
using System.Drawing; 
using Microsoft.Expression.Encoder.ScreenCapture; 

// Added references to: 
// Microsoft.Expression.Encoder 
// Microsoft.Expression.Encoder.Types 
// Microsoft.Expression.Encoder.Utilities 
// WindowsBase 
// System.Drawing (for Rectangle) 

namespace scrcap 
{ 
    class Program 
    { 
     static void Main(string[] args) 
     { 
      ScreenCaptureJob job = new ScreenCaptureJob(); 

      // You can capture a window by setting its coordinates here 
      job.CaptureRectangle = new Rectangle(100, 100, 200, 200); 

      // Include the mouse pointer in the captured video 
      job.CaptureMouseCursor = true; 

      // Output file; you can transcode the xesc file to something else later. 
      // Note that this silently does nothing if the file already exists. 
      job.OutputScreenCaptureFileName = @"C:\Users\arx\scrcap\capture.xesc"; 

      // Do some capture 
      job.Start(); 
      // Wait for a keypress 
      Console.ReadKey(); 
      // And stop 
      job.Stop(); 
     } 
    } 
}
