Flicker is the term used to describe brightness banding or oscillation of images caused typically by artificial lighting driven by a 50 or 60Hz mains supply. We add three controls intended to be used by AEC/AGC algorithms: AeFlickerMode to enable flicker avoidance. AeFlickerPeriod to set the flicker period "manually". AeFlickerDetected to report any flicker that is currently detected.

2023-07-24libcamera: rpi: pipeline_base: Cache sensor formatJacopo Mondi
The format to be applied on the sensor is selected by two criteria: the desired output size and the bit depth. As the selection depends on the presence of a RAW stream and the streams configuration is handled in validate() there is no need to re-compute the format in configure(). Centralize the computation of the sensor format in validate() and remove it from configure().

ABI Compliance: abi-compliance-checker reports 99% binary compatibility and 81.4% source compatibilty between version 0.0.5 and 0.1. - Binary compatibility: 99% - Source compatibility: 81.4% - Total binary compatibility problems: 4, warnings: 2 - Total source compatibility problems: 165, warnings: 7 Now that we have funtional ABI validation, the soname has been updated from libcamera.so.0.0.5 to libcamera.so.0.1. Future releases will now maintain the same soname until an ABI breakage is detected to reduce the repackaging and rebuilding of other components that may use libcamera. The abi-compatibility report can now be generated with the new utility './utils/abi-compat.sh'. Key differences here are due to preventing the installation of internal and private headers in the packaging process, and most of this API compatibility should not be visible to applications with the exception of: - Camera::generateConfiguration ( StreamRoles const& roles ) The StreamRoles type definition has been removed. This is now handled as a Span<StreamRole> to prevent unnecessary allocations and copies. - CameraManager::addCamera ( std::shared_ptr<struct Camera> camera, std::vector<unsigned long>const& devnums ) - CameraManager::get ( dev_t devnum ) - CameraManager::removeCamera ( std::shared_ptr<struct Camera> camera ) These functions of the CameraManager were for use exclusively by the V4L2 adaptation layer, and not intended for use by applications.

The provider g_autoptr variable introduced by commit adb1bbb748a1 ("tests: gstreamer: Test cameras' enumeration from GstDeviceProvider") is left uninitialized when declared. The cleanup function could thus get called on an unitialized variable if the scope was exited before the variable gets initialized. This can't occur here, but gcc 8.4.0 still complains about it: /usr/include/glib-2.0/glib/gmacros.h: In member function ‘virtual int GstreamerDeviceProviderTest::run()’: /usr/include/glib-2.0/glib/gmacros.h:1049:27: error: ‘provider’ may be used uninitialized in this function [-Werror=maybe-uninitialized] { if (_ptr) (cleanup) ((ParentName *) _ptr); } \ ^ ../test/gstreamer/gstreamer_device_provider_test.cpp:37:32: note: ‘provider’ was declared here g_autoptr(GstDeviceProvider) provider; Silence the error by initializing the variable to NULL at declaration time.

2023-07-11v4l2: v4l2_camera_proxy: Prevent ioctl sign-extensionsKieran Bingham
Handling ioctl's within applications is often wrapped with a helper such as xioctl. Unfortunately, there are many instances of xioctl which incorrectly handle the correct size of the ioctl request. This leads to incorrect sign-extension of ioctl's which have bit-31 set, and can cause values to be passed into the libcamera's v4l2 adaptation layer which no longer represent the true IOCTL code. Match the implementation of the Linux kernel and ensure that only 32 bits of the ioctl request are used by assigning to an unsigned int.

The imx708 must drop a single frame on startup - but only when in HDR mode. Non-HDR modes do not need to drop frames. Fix the logic in hideFramesModeSwitch() which currently unconditionally advertises to drop one frame. Unfortunately there is no clear way to tell if the sensor is in the HDR mode.

New TI SoCs from J7 and AM62 family have a camera pipeline that receives data using Cadence's DPHY-RX and CSI-RX bridge. A pixel-grabbing "shim" IP routes this incoming stream of data to the DMA subsystem, to finally store the frame data in memory. The driver for this is not merged in mainline yet, but v7 was posted [1] on linux-media list a few months ago. With some minor fixes, the work-in-progress v8 series [2] works with the simple pipeline handler, so we enable support for this device.

Change the parameter type of `generateConfiguration()` from `const std::vector&` to `libcamera::Span`. A span is almost always preferable to a const vector ref because it does not force dynamic allocation when none are needed, and it allows any contiguous container to be used. A new overload is added that accepts an initializer list so that cam->generateConfiguration({ ... }) keeps working. There is no API break since a span can be constructed from a vector and the initializer list overload takes care of the initializer lists, but this change causes an ABI break.

2023-06-19pipeline: rpi: Do not return an error from pipeline config file handlingNaushir Patuck
If a user provided pipeline config file is not present, or if the version reported in the file is invalid, do not return with an error when creating the pipeline handler. Instead, log a warning message and return success with default pipeline config values used. This now matches the behaviour when the pipeline config file could not be parsed correctly, and we revert to default values.

2023-06-19ipa: rpi: agc: Do not switch to a default if a mode is unavailableNaushir Patuck
In commit 0ee9339331c6, a default metering/exposure/constraint mode is used if a control sets a mode that is not listed in the camera tuning file. Setting a default mode may be undesirable in these cases, so instead keep the agc mode unchanged. This also matches the behaviour for other IPA controls where no changes are made in error conditions.

As the CameraSensor::validateTransform() function compensate for the sensor's mounting rotation, the properties::Rotation value should be adjusted to make sure application that receive already "corrected" images do not get confused by Rotation still reporting a value. Howerver, as an image sensor can only compensate rotations by applying H/V flips, only correct Rotation when the mounting rotation is 180 degrees.

2023-06-18gstreamer: Add enable_auto_focus option to the GStreamer pluginCedric Nugteren
Cameras such as the PiCam 3 support auto-focus, but the GStreamer plugin for libcamera does not enable auto-focus. With this patch auto-focus can be enabled for cameras that support it. By default it is disabled, which means default behaviour remains unchanged. For cameras that do not support auto-focus, an error message shows up if auto-focus is enabled. This was tested on cameras that do not support auto-focus (e.g. PiCam2) and was tested on a camera that does support auto-focus (PiCam3). The test involved setting the focus to AfModeContinous and observing it. However, by not setting "auto-focus-mode" or using AfModeManual as the "auto-focus-mode" both resulting in auto-focus being disabled.

2023-06-17libcamera: pipeline: Register device numbers with cameraKieran Bingham
Register the identified device numbers with each camera as the SystemDevices property. This facilitates camera daemons or other systems to identify which devices are being managed by libcamera, and can prevent duplication of camera resources. As the SystemDevices property now provides this list of devices, use it directly from within the CameraManager when adding a Camera rather than passing it through the internal API.

2023-06-17libcamera: camera_manager: Move {add,remove}Camera to internalKieran Bingham
The CameraManager exposes addCamera and removeCamera as public API calls, while they should never be called from an application. These calls are only expected to be used by PipelineHandlers to update the CameraManager that a new Camera has been created and allow the Camera Manager to expose it to applications. Remove the public calls and update the private implementations such that they can be used directly by the PipelineHandler through the internal CameraManager::Private provided by the Extensible class.
