在c#中捕获游戏屏幕截图最快的方法？（每秒超过20张图像）
如何快速截取整个游戏屏幕？每秒 20-30 次之类的东西？（我想将它们转换为视频）
[[1]] 我尝试过 WMEncoder。结果是 WMEncoder 只能使用一组预配置的编解码器以视频格式 (wma) 捕获屏幕和屏幕区域。 （29 fps 最佳编码结果）。WMEncoder 无法截图。
[[2]] 我已经尝试过 DirectX ：
Surface s = device.CreateOffscreenPlainSurface(
Screen.PrimaryScreen.Bounds.Width,
Screen.PrimaryScreen.Bounds.Height,
Format.A8R8G8B8, Pool.SystemMemory);
device.GetFrontBufferData(0, s);
SurfaceLoader.Save("c:\\Screenshot"+i.ToString()+".bmp", ImageFileFormat.Bmp, s);
这就像 gdi ..非常慢......并且它仅在 DirectX 1.0 中工作，因为 DirectX 2.0 中不存在 SurfaceLoader
我在一些帖子中读到的另一种方法是使用 :
s = device.GetBackBuffer(0, 0, Microsoft.DirectX.Direct3D.BackBufferType.Mono);
，但这使得仅对当前窗口进行屏幕截图。
[[3]] 我尝试使用 Taksi （在 sourceforge.net）...但我不知道如何在 C# 中使用它并使其工作。
请帮帮我...
How can i make screenshoots to the entire game screen very fast? Somthing like 20-30 per second?(i want to convert them to video)

I've tried WMEncoder.Results were that WMEncoder can capture the screen and regions of screen only in a video format (wma) using a set of preconfigured codecs. (29 fps best encode result).WMEncoder can not make screenshots.

I've tried DirectX :
Surface s = device.CreateOffscreenPlainSurface(
Screen.PrimaryScreen.Bounds.Width,
Screen.PrimaryScreen.Bounds.Height,
Format.A8R8G8B8, Pool.SystemMemory);
device.GetFrontBufferData(0, s);
SurfaceLoader.Save("c:\\Screenshot"+i.ToString()+".bmp", ImageFileFormat.Bmp, s);
This works like gdi ..very slow....and it works only in DirectX 1.0 because SurfaceLoader does not exist in directX 2.0
Another way that i've read in some post is using :
s = device.GetBackBuffer(0, 0, Microsoft.DirectX.Direct3D.BackBufferType.Mono);
, but this maks screenshots only to the curent window.

I've tried to use Taksi (at sourceforge.net)... but i don't know how to use it in c# and make it work.
Please help me out...

您确实想连接到 directx，这样您就可以像那个游戏/应用程序一样进行调用。下面是一些执行此操作的网站（大多数都绘制了额外的东西，但我不明白为什么你不能每 x 帧保存后备缓冲区）：

免责声明：我还没有尝试过这个，所以不确定你能得到多少 FPS，但我认为这是最快的方法，因为你在游戏中有效地做到了这一点。
You really want to hook into directx so you can make the calls as if you were that game/application. Below are a few sites that do this (most draw extra things, but i don't see why you couldn't save the backbuffer every x frames):

Disclamer: I've not tried this, so not sure what FPS you can get, however i would think this is the fastest method as you're doing it effectively from within the game.
