您好，我在模拟器上测试，没有问题 ，使用移远的SC20报如下错误，app之间显示 blazeface has stooped，请问是什么原因导致的，谢谢 E/ACameraManager: getCameraCharacteristics: Camera ID does not exist! openCamera: cannot get camera characteristics for camera . err -10001 E/NdkCameraDevice: ACameraDevice_createCaptureRequest: invalid argument! device 0x0 request 0x99b7b430 A/libc: Fatal signal 11 (SIGSEGV), code 1, fault addr 0x4 in tid 14121 (t.blazefacencnn)

@liuweixue001 只有一个摄像头是吗？改一下代码吧 https://github.com/FeiGeChuanShu/ncnn_Android_blazeface/blob/main/ncnn_Android_mediapipe_blazeface/app/src/main/java/com/tencent/blazefacencnn/MainActivity.java#L72

是的，只有一个前置摄像头，这里new_facing设置为0和1都是一样的错误；用android studio的模拟器测试时，夜神一个摄像头，把facing的初始值改为1是可以用的，有可能是权限获取的问题吗，还是说设备的camera id不是0，1之类的整型，我注释掉这两行代码 if (facing < 0 || facing > 1) return JNI_FALSE; 从-1，到1001都试过，报一样的错误，谢谢谢谢

使用模拟器时，前置摄像头可以正常运行程序，切换到不存在的后置摄像头时，报下面的错误，但程序仍不会挂掉，切会前置，还是可以运行的。 E/ACameraManager: Get camera characteristics from camera service failed: Status(-8, EX_SERVICE_SPECIFIC): '10: getCameraCharacteristics:674: Unable to retrieve cameracharacteristics for system only device : ' E/ACameraManager: openCamera: cannot get camera characteristics for camera . err -10000 E/NdkCameraDevice: ACameraDevice_createCaptureRequest: invalid argument! device 0x0 request 0xe8592b70 E/NdkCaptureRequest: ACaptureRequest_addTarget: Error: invalid input: req 0x0, req-targets 0x0, target 0xb8543b90 E/NdkCameraDevice: ACameraDevice_createCaptureSession: Error: invalid input: device 0x0, outputs 0xb8543c90, callbacks 0xff9848c0, session 0xe8592b7c E/NdkCameraCaptureSession: ACameraCaptureSession_setRepeatingRequest: Error: invalid input: session 0x0, numRequest 1, requests 0xe8592b70 I/Choreographer: Skipped 50 frames!
