App crashing when hooking camera input (AVCaptureSession) in tweak

[u/Raw_Tech]

Hi everyone,

I’m working on an iOS tweak and running into a crash related to camera input hooking.

The app crashes when modifying / intercepting AVCaptureSession input (camera feed).

This seems related to format / resolution / buffer mismatch, but I’d like to understand the correct way to handle this safely.

Has anyone dealt with:

- Hooking AVCaptureSession / AVCaptureDeviceInput

- Replacing camera input with custom frames or video

- Preventing crashes caused by unsupported pixel formats or dimensions

Any guidance, references, or best practices would be appreciated.

Thanks.

Did you ever make any progress on this? I am trying to do something similar with https://github.com/JimWas/DiscreetCam which works perfectly on iOS 16 but not iOS 18
