Create CMSampleBuffer from UIImage

UIImageToCMSampleBuffer

import ImageIO
import AVFoundation

var cvPixelBuffer: CVPixelBuffer? {
    var pixelBuffer: CVPixelBuffer? = nil
    let options: [NSObject: Any] = [
        kCVPixelBufferCGImageCompatibilityKey: false,
        kCVPixelBufferCGBitmapContextCompatibilityKey: false,
        ]
    let status = CVPixelBufferCreate(kCFAllocatorDefault, Int(size.width), Int(size.height), kCVPixelFormatType_32BGRA, options as CFDictionary, &pixelBuffer)
    CVPixelBufferLockBaseAddress(pixelBuffer!, CVPixelBufferLockFlags(rawValue: 0))
    let pixelData = CVPixelBufferGetBaseAddress(pixelBuffer!)
    let rgbColorSpace = CGColorSpaceCreateDeviceRGB()
    let context = CGContext(data: pixelData, width: Int(size.width), height: Int(size.height), bitsPerComponent: 8, bytesPerRow: CVPixelBufferGetBytesPerRow(pixelBuffer!), space: rgbColorSpace, bitmapInfo: CGBitmapInfo.byteOrder32Little.rawValue)
    context?.draw(cgImage!, in: CGRect(origin: .zero, size: size))
    CVPixelBufferUnlockBaseAddress(pixelBuffer!, CVPixelBufferLockFlags(rawValue: 0))
    return pixelBuffer
}
    
var cmSampleBuffer: CMSampleBuffer {
    let pixelBuffer = cvPixelBuffer
    var newSampleBuffer: CMSampleBuffer? = nil
    var timimgInfo: CMSampleTimingInfo = kCMTimingInfoInvalid
    var videoInfo: CMVideoFormatDescription? = nil
    CMVideoFormatDescriptionCreateForImageBuffer(nil, pixelBuffer!, &videoInfo)
    CMSampleBufferCreateForImageBuffer(kCFAllocatorDefault, pixelBuffer!, true, nil, nil, videoInfo!, &timimgInfo, &newSampleBuffer)
    return newSampleBuffer!
}

Hello levantAJ is there any way to convert CMSampleBufffer to Data(). As i am creating application which having video recording and I got this sample buffer for video recording. And I want to send this video buffer data to server. So I need to convert this buffer to data.

Thanks in advance

I got this error using your code, and I used CGImage instead of UIImage

CGBitmapContextCreate: unsupported parameter combination:
 	8 bits/component; integer;
 	24 bits/pixel;
	RGB color space model; kCGImageAlphaNone;
