如何使用网络摄像头的Andr​​oid模拟器捕获实时图像？ [英] How to use web camera in android emulator to capture a live image?

问题描述

据我所知，Android模拟器不会有一个摄像头。要捕获实时图像，我们必须使用网络摄像头。我见过code在此网站使用网络摄像头的Andr​​oid模拟器捕获图像，但我不知道如何使用这个code。

解决方案

1. 下载所有网页上列出的源文件：CameraSource，GenuineCamera，HttpCamera，SocketCamera，BitmapCamera和WebcamBroadcaster
2. 创建一个包在您的项目称为com.tomgibara.android.camera和内部发生的前4个源文件。
3. 从这里并安装它。
4. 在编译WebcamBroadcaster使用以下命令：C：\ Program Files文件（x86）的\的Java \ jdk1.6.0_15 \斌\器javac.exe-classpathC：\ Program Files文件（x86）的\ JMF2.1.1e \ LIBWebcamBroadcaster.java或什么是等同于它。
5. 用下面的命令来运行它，并保持运行：java的-Djava.library.path = C：\ Program Files文件（x86）的\ JMF2.1.1d \ lib目录WebcamBroadcaster
6. 使用以下code程序中的：

  CameraSource CS =新SocketCamera（192.168.0.100，9889，320，240，真正的）;
如果（！cs.open（））{
/ *处理未能获得摄像头* /
}
而（/ *某些情况* /）{
cs.capture（画布）//帧捕捉到画布
}
cs.close（）;
 

PS：我一直没能对此进行测试，因为我得到一个错误，当我运行 WebcamBroadcaster

。

PPS：我刚开始与Android尝试，所以今天这一切都可能是错误的。

As far as i know, Android emulator doesn't have a camera. To capture a live image we have to use the web camera. I have seen code in this web site to use the web camera in the android emulator to capture an image, but I don't know how to use this code.

解决方案

1. Download all the source files listed on the page: CameraSource, GenuineCamera, HttpCamera, SocketCamera, BitmapCamera, and WebcamBroadcaster.
2. Create a package in your project called com.tomgibara.android.camera and place the first 4 source files inside.
3. Download JMF from here and install it.
4. Compile WebcamBroadcaster using the following command: "C:\Program Files (x86)\Java\jdk1.6.0_15\bin\javac.exe" -classpath "C:\Program Files (x86)\JMF2.1.1e\lib" WebcamBroadcaster.java or what's equivalent to it.
5. Run it with the following command and keep it running: java "-Djava.library.path=C:\Program Files (x86)\JMF2.1.1d\lib" WebcamBroadcaster
6. Use the following code in your program:

CameraSource cs = new SocketCamera("192.168.0.100", 9889, 320, 240, true);
if (!cs.open()) { 
/* deal with failure to obtain camera */ 
} 
while(/*some condition*/) {   
cs.capture(canvas) //capture the frame onto the canvas
}
cs.close();

PS: I haven't been able to test this because I'm getting an error when I run WebcamBroadcaster.

PPS: I just started experimenting with Android today so all this could be wrong.
