If anything, there will be follow up\nseparate patches for merge separately.\n\nProblem:\nOn nautilus, 26 tests were failing because of \"Fail to open camera\",\nbut more specifically from adb logcat:\n\n```\nE Camera2-Parameters: generated preview size list is empty!!\nE Camera2Client: initializeImpl: Camera 0: unable to build defaults: Invalid argument (-22)\nE CameraService: connectHelper: Could not initialize client from HAL.\nI Camera2Client: Camera 0: Closed\n```\n\nwas found to be root of the problem. The checks triggered are here:\n> Parameters::getFilteredSizes()\n  https://android.googlesource.com/platform/frameworks/av/+/refs/heads/master/services/camera/libcameraservice/api1/client2/Parameters.cpp#2976\n\nnautilus reports higher frame-duration to start with: 34100000\n(in CameraDevice::getStaticMetadata()).\nminFrameDurationNsec is meant to be re-adjusted down the line \nbefore round-up, *if* the difference is < 500 useconds.\n\nOn nautilus, since the difference was much larger than 500 useconds,\nthe re-adjustment failed and libcamera reported a much higher\nframe-duration to upper-layers/libcameraservice. \nThis led to the problem in Parameters::getFilteredSizes(),\nwhere all potential streams for preview are skipped to be added,\ndue to high minFrameDuration.\n\nTo force this re-adjustment, the scope of difference was increased\nto 1200 useconds as done in the patch.\n\nCTS Results on nautilus after applying the changes:\nTotal Run time: 8m 42s\n1/1 modules completed\nTotal Tests       : 221\nPASSED            : 221\nFAILED            : 0\n\n---\n src/android/camera_device.cpp | 5 +++--\n 1 file changed, 3 insertions(+), 2 deletions(-)",
