在Android模拟器中将网络摄像头用作摄像头的示例项目

Question

I've started developing for Android. I want to write an barcode scanning app, but without a way to activate the camera in the emulator it could be annoying.

Does anybody knows a way to use the USB-Webcam of my PC as an Android Camera ? I've searched everywhere i know there is a lib from tomgibara, but it would be really nice if some has got an sample project for this.

At the moment the Emulator only asks for the capturing device, but when i start now the camera app from android i only see this dummy camera site with this chessy squares.

Thank you for all of your help.

Answer 1

You can specify which camera to use and how in the emulator command line using the options

-fake-camera <mode>                   set fake camera emulation mode

where mode can be one of back , front , or off , and

-webcam name=<name>[,dir=<direction>] setup web camera emulation

where name is a valid connected camera name and dir is one of front or back . The connected camera names can be obtained by using the special option -webcam list . For example, in Linux you can obtain something like

List of web cameras connected to the computer:
 Camera 'webcam0' is connected to device '/dev/video0' on channel 0 using pixel format 'YUYV'

单击“确定”后，我可以按照上述方式运行模拟器，但“ fake-camera”选项无济于事=（它允许我选择要使用的照相机，然后单击“确定”，模拟器将启动，但是不使用网络摄像头作为前置或后置摄像头=（是否有可能是不支持的摄像头？如果是，是否支持哪些摄像头？
