How to scale/resize CVPixelBufferRef in objective C, iOS
Clash Royale CLAN TAG #URR8PPP How to scale/resize CVPixelBufferRef in objective C, iOS I am trying to resize an image from a CVPixelBufferRef to 299x299. Ideally is would also crop the image. The original pixelbuffer is 640x320, the goal is to scale/crop to 299x299 without loosing aspect ratio (crop to center). I found code to resize a UIImage in objective c, but none to resize a CVPixelBufferRef. I have found various very complicated examples of object C many different image types, but none specifically for resizing a CVPixelBufferRef. What is the easiest/best way to do this, please include the exact code. ... I tried the answer from selton, but this did not work as the resulting type in the scaled buffer is not correct (goes into assert code), OSType sourcePixelFormat = CVPixelBufferGetPixelFormatType(pixelBuffer); int doReverseChannels; if (kCVPixelFormatType_32ARGB == sourcePixelFormat) { doReverseChannels = 1; } else if (kCVPixelFormatType_32BGRA == sourcePixelFormat) {...

Would you please share with us your .env file configurations so we can check whether it has anything to do with it?(Which is possibly the reason of why you are getting this error)
