Ok what we ended up doing is using the onPreviewFrame method and decoding the data in a seperate Thread using a method which can be found in the android help group. decodeYUV(argb8888, data, camSize.width, camSize.height); Bitmap bitmap = Bitmap.createBitmap(argb8888, camSize.width, camSize.height, Config.ARGB_8888); … // decode Y, U, and V values on the YUV 420 buffer … Read more
In iOS 11, you should use like this : @available(iOS 11.0, *) func photoOutput(_ output: AVCapturePhotoOutput, didFinishProcessingPhoto photo: AVCapturePhoto, error: Error?) { let imageData = photo.fileDataRepresentation() }
Well, it’s taken me fracking forever but I’ve done it! The bit of code I was looking for is [UIDevice currentDevice].orientation; This goes in as so AVCaptureConnection *videoConnection = [CameraVC connectionWithMediaType:AVMediaTypeVideo fromConnections:[imageCaptureOutput connections]]; if ([videoConnection isVideoOrientationSupported]) { [videoConnection setVideoOrientation:[UIDevice currentDevice].orientation]; } And it works perfectly 😀 Woop woop!
androidx.camera:camera-core:1.0.0-alpha10 You can check is torch available or not with this: val camera = cameraProvider.bindToLifecycle(lifecycleOwner, cameraSelector, preview, imageAnalyzer) camera.cameraInfo.hasFlashUnit() And you can enable torch with: camera.cameraControl.enableTorch(true)
HTC has an alternative API that supports this, however it’s only on HTC Sense devices, and as of Gingerbread they’ve changed the permissions so it’s only for their Flashlight app, not third party ones (unless you use root). But on 2.2 HTC devices you can use it by writing a string to /sys/devices/platform/flashlight.0/leds/flashlight/brightness. This controls … Read more
So I figured it out using a combination of the tutorials above and have created the class below. It tweens towards your target and follows it around. Try it out. public interface IFocusable { Vector2 Position { get; } } public interface ICamera2D { /// <summary> /// Gets or sets the position of the camera … Read more
UIImagePickerControllerCameraDeviceFront is not a valid enum for the sourceType property. The sourceType property defines whether you’re using the camera or the photo library. You need to set the cameraDevice property instead. Objective-C self.imgPicker.sourceType = UIImagePickerControllerSourceTypeCamera; self.imgPicker.cameraDevice = UIImagePickerControllerCameraDeviceFront; Swift 2 imgPicker.sourceType = .Camera imgPicker.cameraDevice = .Front Swift 3 imgPicker.sourceType = .camera imgPicker.cameraDevice = .front
You can use SurfaceView and create a CustomView that will open the camera and you can adjust its size in the xml accordingly. Below is a pseudo code. Create a class that extends SurfaceView and open camera inside that CapturePreview.java public class CapturePreview extends SurfaceView implements SurfaceHolder.Callback{ public static Bitmap mBitmap; SurfaceHolder holder; static Camera … Read more
I did some research on this and put together a working(ish) example. Here’s what I found. It’s pretty easy to get the raw data coming off of the camera. It’s returned as a YUV byte array. You’d need to draw it manually onto a surface in order to be able to modify it. To do … Read more
Button otherCamera = (Button) findViewById(R.id.OtherCamera); otherCamera.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { if (inPreview) { camera.stopPreview(); } //NB: if you don’t release the current camera before switching, you app will crash camera.release(); //swap the id of the camera to be used if(currentCameraId == Camera.CameraInfo.CAMERA_FACING_BACK){ currentCameraId = Camera.CameraInfo.CAMERA_FACING_FRONT; } else { currentCameraId = Camera.CameraInfo.CAMERA_FACING_BACK; … Read more
