[code=CSharp]
_clock = new RealtimeClock();
_videoRecorder = new MP4Recorder(

);
_cameraInput = new CameraInput(_videoRecorder,_clock,Camera.allCameras);
_audioInput = new AudioInput(_videoRecorder,_clock,Camera.main.GetComponent<AudioListener>());

UPD:
Answer from NatCorder support
You'll have to reach out to Wikitude's support for this one. CameraInput is simply rendering the camera view to a texture. It is likely the case that Wikitude is overriding how the camera renders, which is why it is offset (cropped). This would have nothing to do with NatCorder, and you can verify this by looking at the CameraInput sources; all it is doing is re-rendering the camera to a RenderTexture by calling `camera.Render`. The camera is expected to render normally, as it did when rendering to the screen.

Hi Maksim,
if you are using Professional Edition, the Background Camera is hidden. With this simple script you can enable it and add to NatCorder.
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class BackgroundCameraEnable : MonoBehaviour
{
public Camera BackgroundCamera;
void Update() {
if(!BackgroundCamera) {
BackgroundCamera = gameObject.transform.Find("BackgroundCamera").GetComponent<Camera>();
BackgroundCamera.gameObject.hideFlags = HideFlags.None;
}
}
}
Kind regards,
Gökhan
thanks, I'll check it out. But why is this information not in the documents? or is it my fault?
Hi Gökhan
This is doesnt work for me or I doing something wrong?!
BackgroundCamera dont draw real world, but seems like in video background is in. but video is incorrect and very laggy. video attached

Hi Maksim,
is this video recorded in the Unity Editor? Does this also happen on the device?
That looks like the Unity Editor running in the background.
Could you send a demo project where I could have a closer look?
Kind regards,
Gökhan

Hi Maksim,
I just saw that we probably don't support this functionality yet. A fix is coming with the next release in a month.
I can send you a custom build, where the background camera isn't hidden at runtime and different resolutions with NatCorder are supported, if you want. Just let me know.
Kind regards,
Gökhan
Thanks, will test it in future.
Also i want to ask. Is it possible to change image recognition for tracking picture in dark colors.
you see at this video. light image fine, darker - no

That should track perfectly. Could you send me the target collection for me to investigate?
Kind regards,

main problem appear when you print image and coloring. If you will hover a camera to screen everything will be ok
Wikitude Technical Support
That's an interesting use case. Let me quickly check with our CV team what best to use as an image target. Meanwhile, you could try to make a transparent image target out of a .png, with just the black lines and a transparent background, in a .zip format. Additionally, let's proceed in another thread regarding this issue please.
Kind regards,
Gökhan
we cant use zip because we MUST have only 1 dataset
