最快速的方法来捕捉游戏画面截图在C＃中？（更多than20每秒图像） [英] fastest method to capture game screen shots in c#?(more than20 images per second)

问题描述

我怎样才能让screenshoots到整个游戏画面非常快？类似的财产以后20-30每秒？（我想将它们转换为视频）

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)

我已经试过WMEncoder.Results分别是WMEncoder只能使用一组预先编解码器的视频格式（WMA）捕获屏幕和屏幕区域。 （29 fps的最佳编码结果）.WMEncoder不能进行截图

[[1]] 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.

我已经试过的DirectX：

[[2]] 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);

这就像GDI ..very慢....而且它只能在DirectX 1.0，因为SurfaceLoader在DirectX 2.0不存在

This works like gdi ..very slow....and it works only in DirectX 1.0 because SurfaceLoader does not exist in directX 2.0

这是我在一些岗位读过的另一种方法是使用：

Another way that i've read in some post is using :

s = device.GetBackBuffer(0, 0, Microsoft.DirectX.Direct3D.BackBufferType.Mono);

，但这MAKS截图只对CURENT窗口。

, but this maks screenshots only to the curent window.

我试图用Taksi（在sourceforge.net）...但我不知道如何在C＃中使用它，使其发挥作用。

[[3]] I've tried to use Taksi (at sourceforge.net)... but i don't know how to use it in c# and make it work.

请帮我...

推荐答案

您真的要挂接到DirectX的，所以你可以，如果你是那场比赛/应用程序打的电话。以下是这样做的几个网站（大多数抽取多余的东西，但我不明白为什么你不能保存后备缓冲每x帧）：

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：我没有尝试过这一点，所以不知道FPS你可以得到，但我认为这是最快的方法你有效地从游戏中做这件事。

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.
