如何使用网络摄像头在Android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模拟器没有摄像头。要捕获实时图像，我们必须使用网络摄像头。我已在此网站中看到代码，以在Android模拟器中使用网络摄像头捕获图像，但我不知道如何使用此代码。

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.

推荐答案

1. 在页面上列出的源文件：CameraSource，GenuineCamera，HttpCamera，SocketCamera，BitmapCamera和WebcamBroadcaster。


2. 在项目中创建一个名为com.tomgibara.android.camera的包， 4个源文件。


3. 从
   
4. 使用以下命令编译WebcamBroadcaster：C：\Program Files（x86）\Java\\ \\jdk1.6.0_15\bin\javac.exe-classpathC：\Program Files（x86）\JMF2.1.1e\libWebcamBroadcaster.java或与之相当的内容。


5. 使用以下命令运行它并保持其运行：java-Djava.library.path = C：\Program Files（x86）\JMF2.1.1d\libWebcamBroadcaster


6. 在您的程序中使用以下代码：

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：我无法测试当我运行 WebcamBroadcaster 时出现错误。

PPS：我刚刚开始使用Android可能是错误的。

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