I updated macOS to 15.0 yesterday, and I found some floating point value support under CMFormatDescriptionExtensions and CVPixelBuffer's Attachment seems to be broken. When I call CMSampleBufferCreateReadyWithImageBuffer() from CVPixelBuffer, macOS 15.0 always fail with floating point values. a. kCMFormatDescriptionExtension_GammaLevel Previous macOS 14.x works with double value like NSString* keyGamma = (__bridge NSString*)kCMFormatDescriptionExtension_GammaLevel; extensions[keyGamma] = @(2.2); b. kCMFormatDescriptionExtension_CleanAperture I am not sure yet but such non-integer value issue also seems to be applied to CleanAperture. kCMFormatDescriptionKey_CleanApertureWidth kCMFormatDescriptionKey_CleanApertureHeight kCMFormatDescriptionKey_CleanApertureHorizontalOffset kCMFormatDescriptionKey_CleanApertureVerticalOffset Also, When I add rational values to extensions, it cannot pass CMVideoFormatDescriptionMatchesImageBuffer() with: kCMFormatDescriptionKey_CleanApertureWidthRational kCMFormatDescriptionKey_CleanApertureHeightRational kCMFormatDescriptionKey_CleanApertureHorizontalOffsetRational kCMFormatDescriptionKey_CleanApertureVerticalOffsetRational Is there any known workaround?
