我们可以在setVideoSource中给出副摄像头的整数值吗？

我想使用设备上可用的辅助摄像头在我的应用程序中录制视频。我使用以下代码来获取辅助摄像头的 int 值：

    int mNumberOfCameras = Camera.getNumberOfCameras();
    CameraInfo cameraInfo = new CameraInfo();
    int mSecondaryCamera;
    for(int i=0;i<mNumberOfCameras;i++)
    {
         Camera.getCameraInfo(i, cameraInfo);
         if (cameraInfo.facing == CameraInfo.CAMERA_FACING_FRONT) {
             mSecondaryCamera=i;
             break;
         }
    }

我使用 MediaRecorder.setVideoSource(mSecondaryCamera); 将视频源设置为辅助摄像头，但它仍然启动主摄像头。。任何人都可以通过提供示例代码或此问题的解决方案来帮助我解决此问题吗？

谢谢

I wanted to record videos in my application using secondary camera available on the device. I am using the following code to get the int value of the secondary camera:

    int mNumberOfCameras = Camera.getNumberOfCameras();
    CameraInfo cameraInfo = new CameraInfo();
    int mSecondaryCamera;
    for(int i=0;i<mNumberOfCameras;i++)
    {
         Camera.getCameraInfo(i, cameraInfo);
         if (cameraInfo.facing == CameraInfo.CAMERA_FACING_FRONT) {
             mSecondaryCamera=i;
             break;
         }
    }

I am using MediaRecorder.setVideoSource(mSecondaryCamera); to set the video source to the secondary camera but its still initiating the primary camera..
Can anyone help me with this by providing a sample code or a solution to this problem?

Thanks
