camera-samples VS LaserDistancer-and-SerialMonitor

For the device formats, what you get on CameraX should be what you get on Camera2, but you can verify with the Camera2Video sample app. It lists the available resolutions and framerates (which notably calculates it in largely the same way that you're already doing).

It's been many years since I used camera APIs, and only camera1. I don't have experience with camera2 and cameraX. The android camera docs https://developer.android.com/training/camerax/choose-camera-library lists the available libraries and in additional resources at bottom of pages, there are samples available. You probably need https://github.com/android/camera-samples/tree/master/Camera2Basic or https://github.com/android/camera-samples/tree/master/Camera2Extensions

https://github.com/android/camera-samples They have both Camera2 and X code.

Have you checked out the official samples: https://github.com/android/camera-samples/tree/master/CameraXBasic

Simple multi picture capture with camera1 and opencv processing is also available at https://github.com/agnostic-apollo/LaserDistancer-and-SerialMonitor/blob/master/app/src/main/java/com/allonsy/laserdistancer/PhotoTaker.java and https://github.com/agnostic-apollo/LaserDistancer-and-SerialMonitor/blob/ea5b1fa1ad62f623ae99a974986dc57741ffd923/app/src/main/java/com/allonsy/laserdistancer/DistanceCalculatorService.java#L273 but it was just for research/testing purposes so not for "production", but it did work.
