如何在安卓模拟器中使用网络摄像头捕捉实时图像? [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.我在这个 网站 中看到了使用 android 模拟器中的网络摄像头进行捕获的代码图片，但我不知道如何使用此代码.

解决方案

1. 下载页面上列出的所有源文件:CameraSource、GenuineCamera、HttpCamera、SocketCamera、BitmapCamera 和 WebcamBroadcaster.
2. 在您的项目中创建一个名为 com.tomgibara.android.camera 的包，并将前 4 个源文件放入其中.
3. 从这里下载 JMF 并安装它.
4. 使用以下命令编译 WebcamBroadcaster:"C:Program Files (x86)Javajdk1.6.0_15injavac.exe" -classpath "C:Program Files (x86)JMF2.1.1elib" WebcamBroadcaster.java 或与之等效的文件.
5. 使用以下命令运行并保持运行:java "-Djava.library.path=C:Program Files (x86)JMF2.1.1dlib" WebcamBroadcaster
6. 在您的程序中使用以下代码:

<块引用>

CameraSource cs = new SocketCamera("192.168.0.100", 9889, 320, 240, true);如果(！cs.open()){/* 处理获取相机失败*/}while(/*某些条件*/) {cs.capture(canvas)//将帧捕捉到画布上}cs.close();

PS:我无法对此进行测试，因为我在运行 WebcamBroadcaster 时遇到错误.

PPS:我今天才开始尝试 Android，所以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)Javajdk1.6.0_15injavac.exe" -classpath "C:Program Files (x86)JMF2.1.1elib" 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)JMF2.1.1dlib" 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.
