Description

Device: Pixel 5
System: Android 12 (S2B1.211112.006)

Phenomenon 1:
Without any modification, select "Back(0) 3840x2160 60 FPS" and the camera has a black screen

Phenomenon 2:
After adding `set(CaptureRequest.CONTROL_AE_TARGET_FPS_RANGE, Range(args.fps, args.fps))` in [here][1], "Back(0) 3840x2160 60 FPS" is displayed normally, [modified][2]FPS is 30 cameras Black screen

Notice:
1. Pixel 6 Pro performs as expected
2. Add `CaptureCallback#onCaptureFailed` in [here][2] to get `CaptureFailure#REASON_ERROR`

Research direction

Reproduce the Pixel 5 Android 12 behavior in Camera2Video/app/src/main/java/com/example/android/camera2/video/fragments/CameraFragment.kt and SelectorFragment.kt, focusing on the linked capture-request and FPS-selection lines. Compare capture failures for 3840x2160 at 60 and 30 FPS, including CaptureFailure.REASON_ERROR. Done means the supported configuration records without a black preview or capture failure on the affected device.
