I am looking to hear directly from Apple Engineers who advocate Core Image for video apps. My experience with DTS has not been good in the last few years, I have found DTS views to be opposite of Apple Engineers when I interacted with them in WWDC labs!

Thanks for the answer. I want to understand what is meant by that (Volume purchases isn't supported by StoreKit 2).To put things in context, I understand AppTransaction has a field originalAppVersion which tells the original version of application purchased by the user. Will this field also identify purchases that were previously made under VPP? Can I rely on this field to identify the version of app originally purchased by the user (be it normal or VPP)? Or this field will not work for VPP?

No, it is not a sandbox user. Do I need to sign-in with a sandbox account for the same?

@Frameworks Engineer So you mean only Apple's camera app on iPhone 15 can save ProRes videos to external USB storage device, but not third party apps?

It now works!

Doesn't work on iOS 17 it seems! ambientViewingEnvironmentData is nil.

The plist itself is type CFData in this case. Nothing works as I said, including the second code sample I posted in the question where I simply copy and paste the attachment from source sample buffer. Feel free to modify and post the sample code you think should work.

@Frameworks Engineer Thanks a lot, though I see the API only works for iPhone 15 family, not earlier devices.

@Frameworks Engineer Ok I undertstand color conversion needs to be done, but is there a way for 32-bit floating point format accomadate 10 bit integer format pixel format for histogram calculation? Or the 10-bit would need to be converted to 32-bit Floating point format first.

Was it resolved? I can not add the same flag in XCode 15.

Hello @gchiste , yes the hardware cost comes to be 1.5 for simple ProRes 1080p@30 fps video. So it would not work for ProRes. But even for non-ProRes presets such as YcbCr420 10 bit where it works, there are frame drops when using 4K@60 fps activeFormat and using AVAssetWriter to encode. This happens even if you merely add preview video data output and do zero processing on the buffers delivered for preview (just a return statement in captureOutput delegate).

I believe originalAppVersion should be present in the AppTransaction, no matter the type of purchase. Only Apple Engineers can verify this, but I can only know once I push my update in the coming few weeks.

Hello @App Store Commerce Engineer Can you please confirm whether AppTransaction.originalAppVersion field will be present for users who purchased the app previously using VPP? Or is this field only present for normal purchases only?

Did you find an answer to this?

I think it is best to avoid using originalAppversion and instead use originalPurchaseDate.
