Same code does not work on 300 RTK but works on mini 3 Pro - Record video

[antonymarion]

Hi Dji,

I get some records (video) on mini 3 Pro with the following code

but on 300 RTK I am getting an error (error code SYSTEM ERROR -7) with no description

    if (CameraKey.KeyIsRecording.create(cameraIndex).get() == true) {
                                    return@run Log.d("INFO", "Camera is already recording")
                                }

                                var callback = object : CommonCallbacks.CompletionCallback {
                                    override fun onSuccess() {
                                        Log.i("VIDEO", "take video success")
                                        ToastUtils.showToast("take video success")
                                    }

                                    override fun onFailure(error: IDJIError) {
                                        Log.e(
                                            "VIDEO",
                                            "take video failed: " + error.description()
                                        )
                                        ToastUtils.showToast("take video failed")
                                    }
                                }

                                flatCameraModule!!.setCameraMode(
                                    DJISDKModel.getInstance(), CameraMode.VIDEO_NORMAL
                                )

                                DJISDKModel.getInstance().performActionWithOutResult(
                                    createKey(
                                        CameraKey.KeyStartRecord, cameraIndex
                                    )
                                )
                                    .subscribe({ CallbackUtils.onSuccess(callback) }) { throwable: Throwable ->
                                        CallbackUtils.onFailure(
                                            callback, (throwable as RxError).djiError
                                        )
                                    }

Please utilize the createCameraKey method to generate a camera key.

I changed with createCameraKey and it does not change anything

Have you tested on a 300 RTK this code?

I replaced the line including the createKeywith

DJISDKModel.getInstance().performActionWithOutResult( createCameraKey( CameraKey.KeyStartRecord, cameraIndex, lensType ) )

and lensType equals the current lens: CAMERA_LENS_ZOOM, or CAMERA_LENS_WIDE, or CAMERA_LENS_THERMAL

By the way, the error description message is still equal to null which does not for troobleshooting...

Yes, it works well on our end. Would you be able to test this key using our sample code?

I will let you know yes using your simple code
