So I'm trying to record videos using AVAssetWriter, process each camera frame (e.g.: adding some watermark or text overlays) by creating CIImage from camera buffer ( CVImageBuffer), add some filter...

I have a project where I use ScreenCaptureKit. For various reasons out of the scope of the question, the format that I configure ScreenCaptureKit to use is kCVPixelFormatType_32BGRA -- I need the r...

Is there a standard performant way to edit/draw on a CVImageBuffer/CVPixelBuffer in swift? All the video editing demos I've found online overlay the drawing (rectangles or text) on the screen and d...

I have an IOSurface-backed CVPixelBuffer that is getting updated from an outside source at 30fps. I want to render a preview of the image data in an NSView -- what's the best way for me to do that?...

I'm building a video export feature for one of my apps. In essence, the video is a series of one of six different images lasting for different (short) durations. The export works fine when I expo...

I am making an swift video app. In my app, I need to crop and horizontally flip CVPixelBuffer and return result which type is also CVPixelBuffer. I tried few things. First, I used 'CVPixelBuf...

How to draw into CIImage (or maybe into CVPixelBuffer, but I guess it easier to add text to CIImage)? not to UIImage I record video (.mp4 file) using AVAssetWriter and CMSampleBuffer (from video, ...

I'm getting the depth data from the TrueDepth camera, and converting it to a grayscale image. (I realize I could pass the AVDepthData to a CIImage constructor, however, for testing purposes, I want...

In CVPixelBuffer object, have one or many planes. (reference) We have methods to get number, heigh, the base address of plane. So what exactly the plane is? And how it constructed inside a CVPixelB...

I am using the iPhone camera to capture live video and feeding the pixel buffer to a network that does some object recognition. Here is the relevant code: (I won't post the code for setting up the ...

I am recording filtered video through an iPhone camera, and there is a huge increase in CPU usage when converting a CIImage to a UIImage in real time while recording. My buffer function to make a C...

I'm having a great deal of difficulty coming up with code that reliably copies a CVPixelBuffer on any iOS device. My first attempt worked fine until I tried it on an iPad Pro: extension CVPixelBuf...

I am using AVCaptureSession & AVCapturePhotoOutput to capture RAW photo data from device's camera in the kCVPixelFormatType_14Bayer_RGGB format. I have got as far as getting the raw photo samp...

How can I get the RGB (or any other format) pixel value from a CVPixelBufferRef? Ive tried many approaches but no success yet. func captureOutput(captureOutput: AVCaptureOutput!, didOutputSampleB...

I'm trying to get a CVPixelBuffer in RGB color space from the Apple's ARKit. In func session(_ session: ARSession, didUpdate frame: ARFrame) method of ARSessionDelegate I get an instance of ARFrame...

I need to create a copy of a CVPixelBufferRef in order to be able to manipulate the original pixel buffer in a bit-wise fashion using the values from the copy. I cannot seem to achieve this with CV...

I get pixels by OpenGLES method(glReadPixels) or other way, then create CVPixelBuffer (with or without CGImage) for video recording, but the final picture is distorted. This happens on iPhone6 when...

I have a CVPixelBuffer that I'm trying to efficiently draw on screen. The not-efficient way of turning into an NSImage works but is very slow, dropping about 40% of my frames. Therefore, I've tri...

I have temporary variable tmpPixelBuffer with pixel buffer data, which is not nil, and when metadata objects are detected I want to create image from that buffer, so I could crop metadata images fr...

I am working on a function in my app to write images from my sample buffer to an AVAssetWriter. Curiously, this works fine on a 10.5" iPad Pro, but causes a crash on a 7.9" iPad Mini 2. I can't fat...

I am currently attempting to change the orientation of a CMSampleBuffer by first converting it to a CVPixelBuffer and then using vImageRotate90_ARGB8888 to convert the buffer. The problem with my c...

I'm trying to resize a CVPixelBuffer to a size of 128x128. I'm working with one that is 750x750. I'm currently using the CVPixelBuffer to create a new CGImage, which I resize then convert back into...

I want to detect ball and have AR model interact with it. I used opencv for ball detection and send center of ball which I can use in hitTest to get coordinates in sceneView. I have been converting...

I try to add a B&W filter to the camera images of an ARSCNView, then render colored AR objects over it. I'am almost there with the following code added to the beginning of - (void)renderer:(...

My camera app captures a photo, enhances it in a certain way, and saves it. To do so, I get the input image from the camera in the form of a CVPixelBuffer (wrapped in a CMSampleBuffer). I perform ...
