Doesn't work in iOS #6

I tried the project in example folder, while it works in android, it always returns empty data in iOS, and shows this error in logs.

VisionCamera.captureOutput(_:didOutput:from:): The Frame Processor took so long to execute that a frame was dropped.

I have the same problem, works good on Android but not on iOS. Any solution?

smisaacs commented 2 years ago

runs perfectly for me on iOS. iPhone XS, using Expo SDK45.

sumi-svmx commented 2 years ago

@smisaacs Which version of iOS did you run it on? For me the text always return empty with iOS v14.1. I have heard it works fine in v15.4.1 Have you set any format/ preset different from the one given in /example?

smisaacs commented 2 years ago

yes. 15.4.1. Only played with framerates and targeting lines vs blocks. Works in all configurations though.

Interesting, this may be a limitation of your hardware and / or Vision Camera. Can you file a bug with vision camera?

hello @aarongrider please help to check on ios 14, i tried but it not work Thanks

Seeing the same. There is an issue with iOS 14 only. Maybe 13 and older as well? There are still people with iOS 14 out there. I played with the orientation but doesn't change anything. Result still empty.
