NatDevice - Media Device API

I just need to see the full logs from logcat. I suspect a padding issue, but I can't be sure without the logs.

 

Also, can you Debug.Log(NatCam.Preview.width+", "+NatCam.Preview.height)?

 

Now I updated the version to 2.1f1 and I just use the GreyCam example for sample but I just faced 2 issues :

1. switch camera to the front always failed(a black screen without any error)
   
   Code (CSharp):

   1. if (NatCam.Camera.IsFrontFacing)
   2.                 NatCam.StartPreview(DeviceCamera.RearCamera, OnStart, OnFrame);
   3.             else
   4.                 NatCam.StartPreview(DeviceCamera.FrontCamera, OnStart, OnFrame);
2. switch camera is very slow and always crash. The preview resolution is 640*480

 

What device are you testing on? Can you upload the full logs in a .txt file?

I pasted logcat output from a few tries on the Nexus6P. I tried to remove all the useless junk.
Hope it helps, thanks!

Preview resolution logs as 1280x720, which the logcat output seems to agree with.

 

will we have a black friday sale for natcam? I am very curious about this asset. If there is any discount in this season, I'll buy it.

 

Unfortunately Unity is not providing a Black Friday discount for NatCam this year.

 

Can you shoot me an email? The problem isn't because of padding. I need to find out what exactly the issue is so I'll be sharing builds of the Android library with you for testing.

 

Hi,
Thanks for the fantastic plugin!
I have a question about android. I'm not using the webcam or WebCamTexture features of Natcorder. Although, on Android it asks to access the camera when opening the app, how can I disable this request?
Thanks again!!
Eric

 

Check the manifest to remove the Camera permission. But you won't be able to use any Camera related feature then.

 

Also, make sure that the NatCorder example scenes are not included in the build.

 

Hi, we (Eric and I) would like to remove the permission prebuild. When you say manifest you are talking about the post build manifest correct? I don’t see a plugin manifest. I am assuming unity creates the permissions from the API used in the plugin? And there is no option to turn it off?

 

That's right. To do it pre-build, you need to make sure that no scenes in the build rely on the camera (so that when Unity performs stripping, there is no code referencing the WebCamTexture class).

 

Ok removing the examples folder did the trick. Thanks everyone!

 

Hello, I bought the natcam plugin to use it with opencv

I'm testing this example :
https://github.com/EnoxSoftware/NatCamWithOpenCVForUnityExample

but it gives me an error with this line:

Code (csharp):

1. public CameraResolution previewResolution = CameraResolution._1280x720;

Assets/NatCamWithOpenCV/Assets/NatCamWithOpenCVForUnityExample/NatCamPreviewOnlyExample/NatCamPreviewOnlyExample.cs(32,16): error CS0246: The type or namespace name `CameraResolution' could not be found. Are you missing an assembly reference?

Assets/NatCamWithOpenCV/Assets/NatCamWithOpenCVForUnityExample/NatCamPreviewToMatExample/NatCamPreviewToMatExample.cs(48,16): error CS0246: The type or namespace name `CameraResolution' could not be found. Are you missing an assembly reference?

maybe this line must be diferent with the new version of natcam ?

 

Ah I have to update the OpenCV example; sorry about that. We removed `CameraResolution`. Use Unity's built-in `Vector2Int` type instead.

 

I will wait for the updated sample because I'm getting some errors when I change that line.
Thanks!

 

I'm working on it right now. You can keep track here.

 

CurrentVersion 2.1f1 is now critical issues in Android.
NatCam.aar used AndroidManifest.xml in <uses-feature android:name="android.hardware.camera2.full" />
is not supported android feature.
so apk file containing that's aar, devices supported is 0 in the play store.

 

A workaround is to export a Gradle project and modify the Android manifest from there. I'm submitting the fix to the Asset Store tomorrow.

 

Hi,
First of all thanks for making this great plugin! Im facing the same issues as jpenery. Green bar in the top and weird colors. Im running NatCam on a Huawei Mediapad T3. I tried running your APK from the NatCamWithOpenCVForUnityExample git, and everything is working fine. Hence I suspect the issue is with the new update to NatCam. Is there any chance that I can get a hold of the old release of NatCam that the APK is running or do I have to wait until you've fixed it in the new update? And if so, when can I expect a fix?

Thanks!
- Carl

 

Hi Carl. We've submitted the update with the fix. We're waiting for Unity to approve it.

 

Thanks for the quick reply! Im looking forward to the update.

 

Hi, I’ve purchased the NatCam plugin but it is crashing/hanging the app on mobile after the capture button is pressed. The image freezes and no error is displayed on the log.
It works fine on the editor using the webcam.
Could I be doing something wrong?

Using:
sony xperia xz1, Android 8.0.0,
Unity 2018.1.8f1
minimum API level 24
NatCam ver. 2.1f2

 

I'm having this same issue when uploading to the google play store. Thanks for submitting the fix.

 

Can you upload the full logs in a .txt file? It might be that you need to reduce the photo resolution because it might be too much for the device to process before sending to Unity.

 

The 2.1f2 update fixes this issue. The update is now available on the Asset Store.

 

Hello Lanre,

when taking a photo on Android, I get these two entries in my LogCat, presumably in the first two lines of NatCamAndroid.
onPhoto:
Bitmap : Called getWidth() on a recycle()'d bitmap! This is undefined behavior!
Bitmap : Called getHeight() on a recycle()'d bitmap! This is undefined behavior!

Is that expected?

(My NatCam version is still 2.0f1 because of the crashes on my Xperia Z3 Compact with higher versions. Maybe you remember; we had a whole email thread around it.)

Also, while I'm here: What do you think is the most performant way to crop a picture I've taken with NatCam to a quadratic texture?

And how does NatCam choose it's camera resolution if I give it certain values and it can't match that? Is there any way for me to say "Use the lowest possible height that bigger or equal to 1440"?

Cheers,
Tobias

 

Hi Lanre,
Initially your update seemed to work but I found some issues - im running my app on a Huawei Mediapad T3 with Android 7.0. First of all changing the resolution does not seem to have any impact. The picture drawn to my screen looks the same regardless of what resolution I pick - I use the greycam example. Im printing the resolution set by the Natcam.preview and I can see that it changes depending on wether im running 640x480 or 1280x720, however the picture looks the same.
Second of all my app is crashing on the Huawei but not when running in the editor. Skimming the logcat, this line seems to break the thing: "02-11 23:59:32.542 14920-15216/? E/art: JNI ERROR (app bug): accessed deleted global reference 0x100b3e". When the app crashes seems random, however I noticed that when im running image processing on the camera stream it seems to appear faster.

I hope you can help.
- Carl

 

hi, I experienced issue when uploading to google play store too. after I update Natcam to 2.1f2, the google play store issue solved. but I've got another error and can't build the app for iOS:



i use natcam and natcorder at the same project.

 

I tried changing the resolution but it did not help. Log summary below:

Nope, this is a bug in that version. I don't recall the issue with the Z3, but have you tried NatCam 2.1? It uses the newer android.hardware.camera2 API, so pretty much everything has been overhauled on Android.

I recommend getting the raw texture data (not Color32[]), and performing a row-by-row copy into a destination pixel buffer. Going through the GPU might seem like the faster alternative, but if you need the pixel data in system memory, then I recommend the row-copy approach. Use Buffer.BlockCopy to perform the copying as it internally does a `memmove`.

NatCam chooses the supported resolution closest to what you pass in. It uses L1 distance to find the closest match. You don't have control over the resolution being less than or greater than.

 

NatCam doesn't have any control over this. We receive the pixel data provided by the camera Hardware Abstraction Layer (HAL), and we forward it to OpenGL ES for preview. Apparent quality changes are entirely up to the device and camera, not NatCam.

Can you upload the full logs in a .txt attachment?

 

Can you share a fuller screenshot? Below the area you cropped should be a list of the symbols that are missing. I need to see that. You can try deleting your built iOS project and re-building from Unity.

 

Has anyone tried Natcam+ OpenCVForUnity? If so, do you have a before/after shot of the camera difference?

 

hi lanre, i deleted the iOS project and re-building from unity. here is another screenshoot. but there's nothing below activity log complete.

Spoiler

and here is some snippet that show warning some plugins need newer iOS version.

Spoiler

Code (CSharp):

1. ld: warning: object file (/Users/***/Build/Libraries/NatCam/Plugins/iOS/libNatRender.a(RenderContext.o)) was built for newer iOS version (12.0) than being linked (9.0)
2. ld: warning: object file (/Users/***/Build/Libraries/NatCam/Plugins/iOS/libNatRender.a(RenderDispatch.o)) was built for newer iOS version (12.0) than being linked (9.0)
3. ld: warning: object file (/Users/***/Build/Libraries/NatCam/Plugins/iOS/libNatRender.a(TransferContext.o)) was built for newer iOS version (12.0) than being linked (9.0)
4. ld: warning: object file (/Users/***/Build/Libraries/NatCam/Plugins/iOS/libNatRender.a(RenderTrigger.o)) was built for newer iOS version (12.0) than being linked (9.0)

 

Although the official example hasn't been updated to NatCam 2.1, you can find benchmarks on the performance difference. See here.

 

When you got the updated NatCam version, it looks like you didn't delete the version you had. Delete NatCam from your project and reimport it from the Asset Store. Then delete the iOS build project, and rebuild from Unity.

 

Hi, did you get a chance to look at the logs?

 

What device is this? Apparently the camera device is encountering an error (outside what we can control). Also, are you setting the preview and photo resolution after calling StartPreview? You should only set them before starting the preview.

 

I had tried setting the resolution before startPreview, but then I got a NullReferenceException. I was able to solve the issue by changing the resolution on the device camera object that is passed to startPreview. Thanks for your help!

 

The T3 issue starting happening with NatCam 2.0f2 and was extremely weird since it crashed in libunity.so/glDrawElements (which you said NatCam doesn't), but it *only* happened when I upgraded from NatCam 2.0f1 to NatCam 2.0f2. A total overhaul sounds like it might be worth checking out again, so I'll do that soon!

Thanks! I don't necessarily need the pixel data in memory, I just wanted the cropped texture as a result. How would you do it via GPU? I tried Graphics.CopyTexture, which worked fine on Windows, but failed on Android. I don't remember how exactly, but I think the resulting texture was just completely white.

Alright. That's not ideal for me, but at least it's "closest" and not "next lowest".

 

You probably tried setting the preview and photo resolution on `NatCam.Camera`. If the preview is not running, `NatCam.Camera` will be null. Instead, get the camera that you will be starting the preview from and set the resolution there:

Code (CSharp):

1. var camera = DeviceCamera.RearCamera;
2. camera.PreviewResolution = ...;
3. camera.PhotoResolution = ...;
4. NatCam.StartPreview(camera, ...);

Setting the preview resolution, photo resolution, and framerate after the preview starts has no effect. You have to set these properties on the camera before calling `StartPreview` with that camera.

 

In that case you can blit with a custom shader that performs the crop. You have to check if your Android device supports Graphics.CopyTexture.

 

Hello Lanre, I have an Apple iPad Pro 11" 2018. I would like to take fotos with the native resulution of the ipads cameras,(both are higher than full hd). Is this possible with NatCam api? Are there any Bugs with your current version and this ipad? thank you in advance.

Edit: the exact modelname of the ipad is : mtxn2fd/a

 

You can set the photo resolution on the device camera to an arbitrarily high value (like (9999, 9999)) and NatCam will pick the highest supported photo resolution for capture.

 

Hi,
I am running into issues on iOS. I was not using any torchmode reference but the camera was throwing an error so I tried forcing torch mode to be false. The error is still there. Is there anything I am missing here?

Uncaught exception: NSInvalidArgumentException: *** -[AVCaptureDevice setTorchMode:] The passed torchMode 0 is not supported - use -isTorchModeSupported: to discover valid torch modes

 

What is the error you face before you set torch mode to false?

 

Hello! Just implemeted NatCam into our project and it's working great, except when i move the camera fast the screen starts tearing. Is there a way to fix this? At the moment i'm just using the NatCam.Preview texture.

Thanks!

 

I removed that line and there is no error now on iOS.
