NatDevice - Media Device API

When the preview is started, it takes some memory. But there shouldn't be any memory accumulating across calls to StartPreview and StopPreview. Can you share a screenshot of the memory profiler in Xcode?

 

Thanks for the reply. But I do not have StartPreview and StopPreview in my NatCam.
The version I have is 2.0f4.
I will upload the screenshot again when I'm ready.

 

When using NatCam on iOS, I need to alternate between pause () and play (). What functions do I need to call to avoid memory leaks? Could you give me your mail? It is a little urgent problem.

 

Upgrade to NatCam 2.1 on the Asset Store. We don't provide support for older versions of our API's. You can email me here.

 

Okay. I will apply the new version.

However, to use the new natcam version, I need to use Unity 2018.2.14 or later. I am using 2018.1.9f1. How should this be handled?

Unity version upgrade seems to be hard to match photon version.

 

You should be able to download NatCam anyway. NatCam works with Unity versions as old as 5.3.

 

Ok Thank You!

 

NatCam is updated as you said. Thank you very much. However, if you use the rear camera on iOS, please confirm that the picture is not taken and the purple screen appears. This is the result from minicam.scene.

 

What is your photo resolution? If it's too big to fit into a GPU texture, then you'll see a purple screen.

 

I am using the resolution of the back camera of the iPhone x.

If so, should the resolution of the rear camera be lowered?

There was no problem using the front camera.

 

Yes, you will probably want to reduce the photo resolution on the rear camera.

 

thank you

 

public void SwitchCamera () {
// Switch camera
if (NatCam.Camera.IsFrontFacing)
{
NatCam.StartPreview(DeviceCamera.RearCamera, OnStart);
DeviceCamera.RearCamera.PhotoResolution = new Vector2Int(1920, 1080);
DeviceCamera.RearCamera.PreviewResolution = new Vector2Int(1920, 1080);
}
else
{
NatCam.StartPreview(DeviceCamera.FrontCamera, OnStart);

}


}

What if you set the resolution yourself when switching to the rear camera? As above.

 

The resolution has to be set before StartPreview is called.

 

How do you enable torch mode?

 

How do you set NatCam to portrait mode? Or to auto detect the phone orientation? Or be based on Unity's orientation

 

DeviceCamera.TorchEnabled.

NatCam handles device rotation and autorotation by itself. You cannot change it.

 

How does NatCam determine device rotation? Is it based on Unity's global device rotation?

 

It's based on Screen.orientation.

Hello everyone,

I've got the next issue

NatCam 2.1.3
Unity 2018.3.5f1
API Level 22
Device: Epson Moverio BT-300 (Android 5.1.1)

Using NatCam preview:

Googling strings
"Bad argument passed to camera service"
and
"Tried to submit a request with a surface that we have not called createStream on"
I found this thread https://stackoverflow.com/questions/32516539/android-camera2-bad-argument-passed-to-camera-service
But that doesn't help me using Unity.

I've also tested the same APK on the Samsung S7 with Android 8 and that works great, but I really need to get results using BT-300.

Any suggestions?

Can you help, please?

 

Hi, any chance you can provide a new lib that works with all your plugins together?

 

You need to grant the app camera permissions.

 

Issues like this are device-specific due to the OEM's implementation of the Android spec. There isn't anything we can do on our end since we're following the Android implementation of the camera2 API spec.

 

Check the NatCorder README on how to resolve these errors.

 

Thanks for the answer!
So I have another way to solve this. Previously I tested the NatCam on this device and the app worked fine. Can I get the older version of NatCam (before camera2 used)?

 

Email me with your invoice number. I should mention that we don't provide support for older versions of our API.

 

Hi Lanre, I followed the instructions on NatCorder's ReadMe file but errors persist. Am I missing something?

Undefined symbols for architecture arm64:
"_OBJC_CLASS_$_GLTransferContext", referenced from:
objc-class-ref in libNatCorder.a(NatCorder.o)

objc-class-ref in libNatCorder.a(NatCorder.o)

ld: symbol(s) not found for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

 

It looks like you are using a much older version of NatCorder. Upgrade to 1.4 on the Asset Store and let me know if you face any issues there.

 

Hi @Lanre

I'm trying to get multiple USB webcams working on an Nvidia Shield TV box, the app detects both cameras but when turning the second camera on the first goes blank. Might your asset help?

 

NatCam doesn't (currently) support running more than one camera. The pipeline is designed with this restriction.

 

NatCam 2.2.0 is out!

And with it comes an updated front-end API which is designed to be more device-oriented. In a nutshell, everything now happens on the `DeviceCamera`: camera properties, starting and stopping the preview, capturing photos, and so on. The new API is leaner (exposing only one class that can be used for every single thing) and more intuitive to use. Upgrade to 2.2.0 today!

 

Hi! I just download the new version, but the VR passthrough sample doesn't work. Do you have an updated sample? Thanks!

 

That example has been archived a long time ago. We aren't updating it anymore.

 

Hi!How can I use the telephoto camera on iPhone 7 plus,or how to get the depth map with NatCam?Thanks!

 

NatCam doesn't support telephoto or depth on iOS.

 

That is weird because, with an old project updated, natCam 2.2.0 is working.
But when I create a new unity project from scratch and import natCam 2.2.0, then it only displays a white screen with no errors.

Tested with :
OnePlus 5 + Unity 2018.3.8f1

I checked the player settings and every thing look OK.
Any idea ?

Thx
Seb

 

Permissions! I'm adding a permissions API in the next minor update.

 

Thank you !
Could you also have a look to the mail I send you (blackScreen when rotating my OnePlus 5)

Thx

 

hello,

I'm using natCam and with the last update ( 2.2.0 ) there have been some small issues, for example I can't activate the torch.

 

Can you share your code? What other small issues are you facing?

 

Code (CSharp):

1. public void TorchOn()
2.     {
3.         if (deviceCamera == null)
4.             return;
5.  
6.         if (deviceCamera.IsRunning == false)
7.             return;
8.  
9.         // Switch camera
10.         if (deviceCamera.IsTorchSupported == true )
11.         {
12.             deviceCamera.TorchEnabled = true;
13.         }
14.     }

in the previous version it worked.

Also issues:
- if I switch the camera (usually after 2 attempts) the preview becomes completely black or white (I also tried your example MiniCam, same result )
- if I put the app on pause

I downloaded NatCam last night. I get the same error any time I call StopPreview() on android using the front facing cam (haven't tried back, I only need front). I even tried this:

if (deviceCamera )
{
deviceCamera.StopPreview();
}

Also, Separate problem on Android: When I turn it to landscape, the video disappears (black screen). When I rotate back, still nothing.

 

Hi @Lanre,

I have just bought your plugin. It seems to be suitable for my needs when testing in Unity Editor, but when trying on the first device i own (Samsung Galaxy Note 3, running Lineage), i get white screen only. Happens for both unmodified GreyCam and MiniCam examples. Logs show that the issue might have to do with RenderScript.

Any ideas?

Best,

What device are you running on? Also, is `deviceCamera.IsTorchSupported` true?

I'm looking into this.

I'll check this out too.

 

You need to check that the device camera is running. NatCam doesn't check for you, so if the preview isn't running but you still call StopPreview, you can expect an exception.

This is a known issue. I'm working on a fix for the next minor update.

 

We have no guarantees for non-official Android builds. Officially, the highest supported Note 3 Android version is 5.0. This is below NatCam's requirement, 6.0. Seems that Lineage OS has a faulty RenderScript implementation.

 

Hi,

I tested it on a samsung s6 and samsung s7.

yes deviceCamera.IsTorchSupported is true, I used an if statement before activate the torch.

At the first time the torch is activated for one second then the torch turns off automatically. If I tried to activate torch a second time this errors appear ( I try to move deviceCamera.TorchEnabled = true; after and before StartPreview, but same result ):

In my experience, this is a bug in camera2. The torch flickers instead of staying on.

Apparently when the preview is running, turning on the torch must be done a different way. I'll implement it and see how it works.
