在Android中使用相机2录制视频时出现错误可以有多种原因，以下是一种可能的解决方法，包含代码示例：

1. 确保在清单文件中添加相应的权限：

2. 在代码中获取相机权限：

private static final int REQUEST_CAMERA_PERMISSION = 1;

private void requestCameraPermission() {
    if (ContextCompat.checkSelfPermission(this, Manifest.permission.CAMERA)
            != PackageManager.PERMISSION_GRANTED) {
        ActivityCompat.requestPermissions(this,
                new String[]{Manifest.permission.CAMERA},
                REQUEST_CAMERA_PERMISSION);
    } else {
        // 已经授予相机权限
        // 进行相机初始化操作
        setupCamera();
    }
}

@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions,
                                       @NonNull int[] grantResults) {
    if (requestCode == REQUEST_CAMERA_PERMISSION) {
        if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
            // 相机权限已授予
            // 进行相机初始化操作
            setupCamera();
        } else {
            // 相机权限被拒绝
            Toast.makeText(this, "相机权限被拒绝", Toast.LENGTH_SHORT).show();
        }
    }
}

3. 初始化相机：

private CameraDevice mCameraDevice;
private CameraCaptureSession mCaptureSession;
private CaptureRequest.Builder mPreviewRequestBuilder;
private ImageReader mImageReader;

private void setupCamera() {
    CameraManager cameraManager = (CameraManager) getSystemService(Context.CAMERA_SERVICE);
    try {
        String cameraId = cameraManager.getCameraIdList()[0]; // 获取第一个相机的ID
        cameraManager.openCamera(cameraId, new CameraDevice.StateCallback() {
            @Override
            public void onOpened(@NonNull CameraDevice camera) {
                mCameraDevice = camera;
                // 进行预览等其他操作
                createCaptureSession();
            }

            @Override
            public void onDisconnected(@NonNull CameraDevice camera) {
                // 相机断开连接
                mCameraDevice = null;
            }

            @Override
            public void onError(@NonNull CameraDevice camera, int error) {
                // 相机打开错误
                mCameraDevice = null;
            }
        }, null);
    } catch (CameraAccessException e) {
        e.printStackTrace();
    }
}

private void createCaptureSession() {
    try {
        // 创建相机预览和录制会话
        List outputSurfaces = new ArrayList<>();

        // 添加预览的Surface
        SurfaceTexture surfaceTexture = previewTextureView.getSurfaceTexture();
        surfaceTexture.setDefaultBufferSize(previewWidth, previewHeight);
        Surface previewSurface = new Surface(surfaceTexture);
        outputSurfaces.add(previewSurface);

        // 添加录制视频的Surface
        mImageReader = ImageReader.newInstance(videoWidth, videoHeight,
                ImageFormat.YUV_420_888, 1);
        Surface videoSurface = mImageReader.getSurface();
        outputSurfaces.add(videoSurface);

        // 创建请求构建器
        mPreviewRequestBuilder = mCameraDevice.createCaptureRequest(CameraDevice.TEMPLATE_PREVIEW);
        mPreviewRequestBuilder.addTarget(previewSurface);
        mPreviewRequestBuilder.addTarget(videoSurface);

        // 创建相机会话
        mCameraDevice.createCaptureSession(outputSurfaces, new CameraCaptureSession.StateCallback() {
            @Override
            public void onConfigured(@NonNull CameraCaptureSession session) {
                mCaptureSession = session;
                // 开始预览
                startPreview();
            }

            @Override
            public void onConfigureFailed(@NonNull CameraCaptureSession session) {
                // 相机会话配置失败
            }
        }, null);
    } catch (CameraAccessException e) {
        e.printStackTrace();
    }
}

private void startPreview() {
    try {
        // 设置预览请求为连续自动对焦
        mPreviewRequestBuilder.set(CaptureRequest.CONTROL_AF_MODE,
                CaptureRequest.CONTROL_AF_MODE_CONTINUOUS_PICTURE);
        // 设置预览请求为自动曝光
        mPreviewRequestBuilder.set(CaptureRequest.CONTROL_AE_MODE,
                CaptureRequest.CONTROL_AE_MODE_ON_AUTO_FLASH);
        // 设置预览请求为屏幕方向
        mPreviewRequestBuilder.set(CaptureRequest.JPEG_ORIENTATION,
                getWindowManager().getDefaultDisplay().getRotation());

        // 设置预览回调
        m
