NatDevice - Media Device API

If you want to record just the camera preview, see this document in the docs.

If you can't switch to the front cam, then it is likely because some other client (like WebCamTexture) or app has access to the camera and has not relinquished it. NatDevice does not support autorotation; UI best practices is to lock the app orientation when the camera preview on screen (you can cross-check this with most camera apps in the wild).

 

Hey there Shane! First, on Windows NatDevice falls back to WebCamTexture as we don't have a native camera implementation (same on macOS). As for finding a specific camera, you can filter by name when you create the query. Just define a criterion that checks the UID of the device against whatever UID you want.

 

Okay, so here is the whole log:

Do you mind editing this to use code tags? Pasting it directly into your response makes the page harder to navigate. Also, this is the same crash as the one I've reported to Apple. I'm waiting to hear back.

 

Thanks Lanre! Can you give an example of how to use a criterion with a uniqueID? I'm not sure how that syntax would look.

 

Code (CSharp):

1. var criterion = device => device.uniqueID == "Whatever unique ID";

 

Hi, I've purchased the plugin for the purposes of capturing high res images via webcam on Windows.

Having played around with the plugin, I can't seem to be able to use any attached or integrated webcams as a CameraDevice, only GenericCameraDevice's are detected.

Is it possible to capture high res images via webcam on Windows at all?

Thanks

 

On standalone platforms, NatDevice falls back to WebCamTexture. Webcams don't offer nearly as much functionality as mobile cameras.

 

Hello, I've been trying to use NatCorder to record video with microphone input, using the ReplayCam demo as an example. On iOS this works fine, but on Android the microphone input is very low. I can't do much about this myself as the audio input is based on the audio source component, and the volume for that is already set to max.
If I used NatDevice, would there be a way around this? I don't have NatDevice yet, and I'm wondering if it would be a good idea to get it if it fixes this. Thanks for the work on the NatSuite. There really should be more stuff exposed to Unity from mobile devices like this in the first place.

 

If the volume is low from the microphone itself, then there isn't anything you can do to rectify it except manually amplifying the samples in code. Chances are that NatDevice won't help here because the issue is coming from a level below both NatDevice and Unity's Microphone API.

In this case specifically, microphones don't expose any volume or attenuation controls.

 

Hi @Lanre, we have been using NatMic and tried to move over to NatDevice recently. There were however couple of issues we found out which sadly made our app unable to use NatDevice.

a) NatDevice seems to require Camera at all times, even if we are only requesting access for Microphone and using microphone device.
Can we ban NatDevice to request Camera permission? It seems to add it automatically in Android manifest as well, which can be removed but we got stuck in iOS.

b) NatDevice is only compiled for iOS arm64. Is it not armv7 compatible? Can you compile armv7 compatible version of NatDevice ? . We are still supporting armv7 and haven't decided to stop supporting it.

 

I'm not sure what you mean by 'require the camera at all times'. We need to specify the camera and microphone permission tags in the manifest. There is no way around this.

NatDevice does not ask for permissions when the app starts. So if you are seeing a permissions dialog, then it is likely because you have WebCamTexture somewhere in your scene. Unless you start a camera device or explicitly call RequestPermissions, NatDevice doesn't ask for permissions.

NatCorder, NatDevice, NatShare, and NatReader all require iOS 11+, and no armv7 device supports iOS 11, so they are all built exclusively for the arm64 architecture. See the data on this page.

 

Thanks for quick reply. Seems we missed that iOS 11+ requirement. Luckily for us updated NatMic fixed our issues. We called RequestPermission to Mic, and when we did then we got popup for that first, but then after we accepted Mic permissions, Camera permission popped up. If we did not request specific permission then we always got Camera first and then Mic. This always happened when using builtin Mic with echo cancellation on iPhone 8 plus.

 

Well I used NatDevice and somehow it fixed the volume problem I was having. I think it was using Unity's Microphone API that was the problem maybe? I don't really know.

And as far as things being exposed, I just mean that I think that some of these device functions should be easier to access within Unity, at least from my perspective.

Incidentally enough, I have another issue, this time with iOS. I'm basically copying the ReplayCam example exactly with iOS. The first recording in the application works fine. Then if the user quits and re-opens the application, and records again, the audio is delayed. This can be repeated to further delay the audio recording.

I'm pretty sure this occurs with the default ReplayCam example, without anything changed.

EDIT: Well I fixed my issue by using Natcorder + NatDevice on iOS. Before, I was only using NatCorder. I think the above issue still occurs in the ReplayCam example on both platforms. Also, on iOS, I had to use the AudioSettings.outputSampleRate instead of the sample rate from the audioDevice, as was shown in NatDevice. The sample rate should be the same with either option, from what I can tell, but somehow that made a difference. Maybe it was something else I did, but I can't pinpoint what else it could've been.

 

Hi, in order to make my object detection scene with OpenCvForUnity on an android phone better (brighter camera and high fps ) I purchased the NatDevice from asset store.

I tested on Xiaomi Redmi 5A and on Samsung galaxy S10

and the problem is that while with WebCamTextureToMat Helper when you set Initialize (Screen.width, Screen.Height)

it is covering the whole screen, in the NatCamWebCamTexturePreviewHelper when i set the resolution 1080x1920 or Initialize(Screen.width, Screen.heigth) is not goif full screen

Why is that happening???

 

It's really hard to tell, no clue.

I'm not able to reproduce this, and quitting the application (as opposed to suspending it) should definitely not produce an issue like this. Can you confirm?

This is a known bug on iOS. For some reason iOS reports the wrong sample rate before the first time the microphone starts. Immediately after that, it reports the correct value. I'm working on it.

 

I'm not too sure how the NatDeviceWithOpenCVExample UI is setup, but you might want to check that the raw image or UI plane is set to cover the entire screen. You can use an AspectRatioFitter component for this.

 

Hi Lanre,

Any update on the crash on EXC_BAD_ACCESS from Bridge.CameraDevices ?

 

I am referring to the NatDeviceCamPreviewToMatHelperExample scene
With an orothgraphic camera and a quad as the first object to show
When i set Initialize(Screen.width, Screen.Height) (canvas size: 1080,1920) in a Pixel 1 without adding the compontent Aspect Ratio Fitter
it goes full screen but not in a samsung galaxy s 10

Any Idieas, is it the phone that cant take that resolution

 

For the bug I was reporting on regarding quitting the application, I actually meant suspending it. That was my bad. I fixed that by using NatDevice's audio device system instead of using Unity's Microphone API. Maybe I was just using the Unity Microphone system wrong, but whatever works.

Good to know the other known bug. I'll just have to remember about using the other reported sample rate for iOS for now. Thanks!

 

Not just yet, Apple hasn't gotten back to me. I got a report that NatCam, NatDevice's predecessor, doesn't have this issue but it is expected since NatCam was built with an older version of the iOS SDK. In any case I'm working to deploy the old code and do an incremental upgrade to NatDevice's current code in hopes to isolate the cause of the crash.

 

I'm not sure why you are using an orthographic camera. Why not just use a normal perspective camera along with a UI canvas? Then make sure your UI panel has an aspect ratio fitter.

 

Sent an email to the email I've used before (the o**********f one)

I have separate suspicions that Google VR plugin for Unity may be to blame, (at the very least it's causing issues of its own,) but soon I'll be swapping it out with their new native Cardboard plugin that's getting released this week, so I'll see, I guess. Let me know if the XCode logs are useful!

 

Hi I have both NatCorder and NatDevice and I am having a build error saying that I have two instances of plugins with the same name.

In my assets folder I have a “NatSuit” (NatCorder) folder and a “NatDevice” folder which both have a “plugin” folder and both have an “Android” folder.

The files that have the same name are Natcorder and NatRender (could be NatRendor)

If any one has had this issue do they have any tips on how to fix it?

(sorry for the unsure-ness about the file name, it’s a question for the work I have to do tomorrow and I’m not at work)

 

Sorry for the late response; I just responded to your email.

 

I responded to your email.

 

Hi, I'm getting worse quality photos with the plugin compared to the camera on my Samsung. The colors are way sharper and details a lot clearer in the original camera app. Any idea of how to fix this?

 

The only thing you can check is that your photo resolution is high (set the photo resolution to something like (9999, 9999)). It is not uncommon for camera apps to perform image post-processing like sharpening and color enhancement. So you can't use them as a baseline.

 

are they doing this at runtime? The original samsung camera "preview texture" is also a lot better.

 

Realtime image filters are everywhere; in fact this is Snapchat's entire product.

 

It seems the documentation link in the very first post here doesn't work any more.

 

I'll fix that. I've been migrating to new online docs. I should note that the NatDevice docs are currently incomplete.

 

Hi Lanre,
I try get timestamp and samplebuffer for my purpose, but debug always result = 0

Code (CSharp):

1. async void Start () {
2.             // Request mic permissions
3.             if (!await MediaDeviceQuery.RequestPermissions<AudioDevice>()) {
4.                 Debug.LogError("User did not grant microphone permissions");
5.                 return;
6.             }
7.             // Create a media device query for audio devices
8.             var deviceQuery = new MediaDeviceQuery(MediaDeviceQuery.Criteria.AudioDevice);
9.             // Get the device
10.             device = deviceQuery.currentDevice as AudioDevice;
11.             Debug.Log($"{device}");
12.             if (device != null)
13.                 device.StartRunning(OnSampleBuffer);
14.         }
15.  
16.         void OnSampleBuffer (float[] sampleBuffer, long timestamp) {
17.            
18.             //var position = Microphone.GetPosition(null);
19.  
20.             Debuger.Log("timestamp: " + timestamp);
21.             Debuger.Log("Max: " + sampleBuffer.Max());
22. }

so I don't understand it
and with Unity API, it has Microphone.GetPosition(null), so with NatDevice how we can get it value?

 

I'm a bit confused. Are you saying that the array max is always zero? If so, then what device does this happen on? If you are testing on iOS, this will happen if the app doesn't have microphone permissions.

 

Hi Lanre,
we've purchased the upgrade but it is crashing the editor immediately.
This is reproducible in a blank project with only the plugin imported, trying to run the minicam scene
I have already tried various unity versions to no avail: 2019.2.6f1, 209.2.17f, 2019.3.0f5, and 2019.3.13f1. All on MacOS.
Please advise.

 

I responded to your email. It's likely because of macOS Catalina's permissions.

 

Hi, I want to record video that Avatar Lipsyncing what I'm talking about, using NatCorder, NatDevice and Oculus Lipsync on Oculus Quest.
I tried and got Oculus Lipsync getting an error "Timeout initializing microphone".
Can't NatDevice and Lipsync asset be used together?
Could you give me any advice if possible?

 

Two clients cannot access the camera or microphone at the same time. So if your lipsyncing uses the microphone, NatDevice cannot use it and vice versa.

 

Hi,

I just updated to the latest versions of NatSuite and NatDevice. Everything works like a charm on Android, but when i run the same code on iOS, it only finds one microphone (built-in microphone), which makes the audio lag and also mute and then play it all really fast at the end. I have tested this on iPhone 7 and XS. Shouldnt they find more than one microphone?
This is the code for the microphone:

Code (CSharp):

1.         // Request mic permissions
2.         if (!await MediaDeviceQuery.RequestPermissions<IAudioDevice>())
3.         {
4.             Debug.LogError("User did not grant microphone permissions");

Hi Lanre, I am seeing similar to what is said in the above post.

I am seeing:

2 mics on Android (Both built in) Galaxy S9.
1 mic on iOS (iPhone Microphone) iPhone 8.

Android recording and playback are fine, using built in mics.
Unity Editor recording and playback are fine.

iOS constantly fails after CommitSamples.
In ClipRecorder.cs - FinishWriting() - AudioClip.Create throws an exception claiming

ArgumentException: Length of created clip must be larger than 0.

(I read a previous post suggesting this happens on first attempt only but I get it constantly on iOS)

I've immediately logged out the variables prior to this call to AudioClip.Create in this function.

byteSamples.Length = 667648
totalSampleCount = 166912

It's also worth knowing that:
Neither platform running Natdevice will recognise a connected bluetooth mic as a listed device for selection.
Neither platform will record from the bluetooth mic. (Android will record from built in mics and playback audio in the bluetooth headset.)

Any help or advice would be very appreciated.

Edit: FYI - this is post successful permissions acceptance.

 

Hi Lanre,
sorry I'm busy on other project so I forget this
"Are you saying that the array max is always zero" -> yes, both timestamp and sampleBuffer.Max() always log 0
"If you are testing on iOS, this will happen if the app doesn't have microphone permissions"-> I think microphone device work fine because video after record have sound
thanks!

 

This is correct behaviour. NatDevice will only find microphones for each connected microphone. So if you have no external devices (like AirPods) plugged in, then there's only going to be one device. If you have headphones, that's 2 devices. And so on.

This audio lag could be an issue we have been facing with iOS where it incorrectly reports the sample rate and channel count until after the microphone has started recording. We have fixed this in the upcoming 1.0.2 update.

In the next update, this will be only 1 built-in microphone. The reason why NatDevice reports two is because of echo cancellation (one supports, the other doesn't). We've changed this such that `echoCancellation` is now a read-write property on the audio device.

This is weird. I can't reproduce it on my end, and the number of samples is clearly non-zero. It could be a Unity bug.

On Android, NatDevice doesn't detect external microphones as independent devices. This is because the Android API's don't expose this until API level 23, and NatDevice's minimum is 21. On iOS, you should be getting a device for bluetooth microphones on NatDevice 1.0.1 (the current Asset Store version). For example, I get my AirPod Pro's as a second audio device after the built in mic.

 

This definitely sounds like you don't have permissions. Check the device's Settings to confirm.

 

Lanre, thank you for the response.

it was quite informative, can you confirm the version of Unity that you are using?

I'll test mine against that version and see what happens.

 

I use Unity 2019.3.

 

Good afternoon! First of all amazing asset!

I'm using it to record audio, however for example on Windows my microphone list shows 2 devices, which would be the plugged in one (which records) and a virtual oculus one which doesn't, how can I select a default or make sure that the one selected is indeed recording?

So current behaviour when I use "query.currentDevice" gives me the virtual one which doesn't record I have to manually set the index to 1, which then doesn't work on all platforms I support, how can I default to a mic that actually records?

Thank you so so much!

 

@Lanre - Hope all is well and you managed to stay healthy. Sent you an email recently about a bug i was facing with Nat Device.

I have a literal copy and paste straight from your documentation/readme and my camera device keeps coming back as null when I try to call the command capture photo.But interestingly i do see a camera feed.

Using unity 2019.3.12

 

I am not familiar with this concept of virtual microphones, or microphones which record or don't record. Windows doesn't make any distinction; MediaFoundation reports audio capture devices, and we simply forward these to Unity. As such I don't think there is anything we can do on our end. A simple workaround for you is to search for a device that is not the Vuforia microphone.

 

I responded to your email. You need to check if you have a `CameraDevice` instance or a `WebCameraDevice` instance. The former supports photo capture; the latter doesn't.

 

Hello @Lanre.

We have just purchased your plugin and are running into a slight issue. We use your plugin with an Android tablet (Samsung Galaxy A T550 - with a 4:3 aspect ratio). In portrait mode and using the back camera, the camera feed preview is displayed properly but when we call the CapturePhoto() the capture is flipped horizontally.

Unfortunately this way text become unreadable unless we flip back ourselves the resulting texture2D. We could not find a way to have acapture that matches the preview using only functions from your plugin.

Is this a bug or is there a way to configure this?

Thanks.
