deepAR and IVS Isues

this is privous topic read this first plz

Here’s the translation of the provided content:

I realized that I made a mistake previously. When I set up the device configuration using the frontCamera, it caused the screen to freeze.

The current issues are:

When only the microphone is set up and played back on the AWS IVS website, the microphone isn’t broadcasting properly.
The customImageSource is capturing the default camera view, not the image with the deepAR filter. I even saved the sampleBuffer as an image to verify this.

This code pertains to the CustomImage source, and it’s a test code that allows verification by saving it as a photo.

    func frameAvailable(_ sampleBuffer: CMSampleBuffer!) {
        customImageSource?.onSampleBuffer(sampleBuffer!)
        
       // CMSampleBuffer를 UIImage로 변환
        if let image = self.imageFromSampleBuffer(sampleBuffer: sampleBuffer) {
           // UIImage를 사진 앱에 저장
           UIImageWriteToSavedPhotosAlbum(image, nil, nil, nil)
      }
    }

    func imageFromSampleBuffer(sampleBuffer: CMSampleBuffer) -> UIImage? {
        if let imageBuffer = CMSampleBufferGetImageBuffer(sampleBuffer) {
            CVPixelBufferLockBaseAddress(imageBuffer, CVPixelBufferLockFlags(rawValue: 0))
            
            let baseAddress = CVPixelBufferGetBaseAddress(imageBuffer)
            let bytesPerRow = CVPixelBufferGetBytesPerRow(imageBuffer)
            let width = CVPixelBufferGetWidth(imageBuffer)
            let height = CVPixelBufferGetHeight(imageBuffer)
            
            let colorSpace = CGColorSpaceCreateDeviceRGB()
            
            let bitmapInfo: CGBitmapInfo = [CGBitmapInfo.byteOrder32Little, CGBitmapInfo(rawValue: CGImageAlphaInfo.premultipliedFirst.rawValue)]
            
            let context = CGContext(data: baseAddress, width: width, height: height, bitsPerComponent: 8, bytesPerRow: bytesPerRow, space: colorSpace, bitmapInfo: bitmapInfo.rawValue)
            
            if let cgImage = context?.makeImage() {
                let image = UIImage(cgImage: cgImage)
                CVPixelBufferUnlockBaseAddress(imageBuffer, CVPixelBufferLockFlags(rawValue: 0))
                return image
            }
            
            CVPixelBufferUnlockBaseAddress(imageBuffer, CVPixelBufferLockFlags(rawValue: 0))
        }
        
        return nil
    }

this is IVS setup Code

 func setupIVS() {
        do {
            let broadcastSession = try IVSBroadcastSession(configuration: IVSPresets.configurations().standardPortrait(),
                                                           descriptors: IVSPresets.devices().microphone(),
                                                           delegate: self)

      
            let customImageSource = broadcastSession.createImageSource(withName: "customSourceName")
            
            broadcastSession.attach(customImageSource, toSlotWithName: "customSourceSlot")
            self.customImageSource = customImageSource
            
            self.broadcastSession = broadcastSession
            
            let url = URL(string: kIngestServer)
            let key = kStreamKey
            try broadcastSession.start(with: url!, streamKey: key)
        } catch {
            assertionFailure("IVSBroadcastSession faild to initialize.")
        }
    }

and 1 more question the frameAvailable function is not calling evert Frame
why???

**class** DeepARViewController: UIViewController, DeepARDelegate {

func setupDeepARAndCamera() {
        self.deepAR = DeepAR()
        
        self.deepAR.delegate = self
}


 func frameAvailable(_ sampleBuffer: CMSampleBuffer!) {
        // this part dosent called everyFrame or not even Once
    }


}

Can you check that DeepAR is initialized and that the camera started? If possible can you share more of your code or reproduce the issue on our quickstart example?

I am using DeepAR in SwiftUI, and I have three files where I use UIViewRepresentable to adapt DeepARViewController for use in SwiftUI. However, the DeepARDelegate is not working for some reason. Can you please explain why?

and if you want to more info then i can send my code

this is View

The problem is quite complex, but I’ll explain it briefly.

  1. To use the deepAR ViewController in SwiftUI, I’m using UIViewRepresentable. However, for some reason, the frameAvailable function of DeepARDelegate is not being called. I explained this issue in the response above, so please refer to that for more details.
  2. In the case of deepAR with IVS, I set up the microphone connection using the following code inside the setupIVS() function:
let broadcastSession = try IVSBroadcastSession(configuration: IVSPresets.configurations().standardPortrait(),
                                               descriptors: IVSPresets.devices().microphone(),
                                               delegate: self)

And I’m using it like this in the frameAvailable function:

func frameAvailable(_ sampleBuffer: CMSampleBuffer!) {
    customImageSource?.onSampleBuffer(sampleBuffer!)
}

I have a basic understanding of the code overall, but there are two issues here:

1.When watching IVS in this state, the microphone is broadcasting correctly, but the screen is not rendering.
2. Additionally, I tested whether the sampleBuffer is correctly converted into an image within the frameAvailable function:

  • (1) When there is no mask filter, the image is displayed correctly.
  • (2) When there is a mask filter, a white screen is saved as an image.

I’m not sure if these issues are causing problems with the live broadcast output, but at the moment, it seems to be the case.

So, even though you may be very busy, could you please download and test the sample code you provided at GitHub - DeepARSDK/ios-deepar-amazon-ivs-sample-integration? Also, please share the version you are using anout deepAR and IVS SDK

Just for reference, I used the provided deepAR with IVS sample code with only the necessary unique values like the appId changed, but it is not functioning as expected.

this is GitHub - DeepARSDK/quickstart-ios-swift: DeepAR SDK for iOS example project code i just added only LicenseKey for test and added frameAvailable function and
that function[frameAvailable] not calling every frame not even once

DeepAR version: 5.4.3

so im wondering
why frameAvailable function working in this code (GitHub - DeepARSDK/ios-deepar-amazon-ivs-sample-integration)

and why its not woring with quickstart-ios-swift code what is different?

    func frameAvailable(_ sampleBuffer: CMSampleBuffer!) {
        print("프레임 도는중") 
    }

    var path: String? {
        return Bundle.main.path(forResource: self, ofType: nil)

}

As it says in the API reference, in order for frameAvailable() to be called, startCapture() needs to be called first. So placing a startCapture() call inside didInitialize() should make it work.

thank you its works
and can you check other question too?
which is IVS for LiveStreaming
if i use this sampleCode only mic its works not camera
so

    func frameAvailable(_ sampleBuffer: CMSampleBuffer!) {
        customImageSource?.onSampleBuffer(sampleBuffer!)
    }

when i append sampleBuffer on CustomImageSource
its not work that i expected or guide that youguys provided

Can you go into a bit more detail? So the camera is not working on the example?

To be precise, after registering only the necessary license key in the sample code and running it, if you go to the IVS website, you can see the current live streaming screen is in a live state, but only sound is transmitted on a black screen. Also, inside the ‘setIupVS’ in the sample code, it’s set to:

let broadcastSession = try IVSBroadcastSession(configuration: IVSPresets.configurations().standardPortrait(),
                                                           descriptors: IVSPresets.devices().microphone(),
                                                           delegate: self)

It is set to the microphone (In other words, it seems like the sample code is not working properly).

Any updates? its been a week ㅠㅠ
