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.

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.

2023-06-06libcamera: rkisp1: Assign sizes to rolesJacopo Mondi
Currently each RkISP1 path (main and self) generate a configuration by bounding the sensor's resolution to their respective maximum output aspect ratio and size. Size maxResolution = maxResolution_.boundedToAspectRatio(resolution) .boundedTo(resolution); In the case of self path, whose maximum size is 1920x1920, the generated configuration could get assigned unusual sizes, as the result of the above operation. As an example, with the imx258 sensor whose resolution is 4208x3118, the resulting size for the Viewfinder use case is an unusual 1920x1423.

The generateConfiguration() implementation in the Rockchip RkISP1 pipeline handler uses by default the self path (if available) for the Viewfinder and VideoRecording StreamRoles. The validate() implementation, at the contrary, prefers using the main path, when available, for all streams. As the self-path is limited in output resolution to 1920x1920, generating a configuration using the self path limits the maximum stream size to 1920x1920, while higher resolutions can be obtained by using the main path.

2023-05-31py: Move to mainline pybind11 versionTomi Valkeinen
We are using pybind11 'smart_holder' branch to solve the Camera destructor issue (see the comment in this patch, or the commit that originally added Python bindings support). As it would be very nice to use the mainline pybind11 (which is packaged in distributions), this patch adds a workaround allowing us to move to the mainline pybind11 version. The workaround is simply creating a custom holder class (PyCameraSmartPtr), used only for the Camera, which wraps around the shared_ptr. This makes the compiler happy. Moving to mainline pybind11 is achieved with: - Change the pybind11 wrap to point to the mainline pybdind11 version - Tell pybind11 to always use shared_ptr<> as the holder for PyCameraManager, as we use the singleton pattern for the PyCameraManager, and using shared_ptr<> to manage it is a requirement - Tell pybind11 to always use PyCameraSmartPtr<> as the holder for Camera - Change the meson.build file to use a system-installed pybind11 Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ideasonboard.com> Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>

Files opened internally in libcamera without the O_CLOEXEC file will remain open upon a call to one of the exec(3) functions. As exec() doesn't destroy local or global objects, this can lead to various side effects. Avoid this by opening file descriptors with O_CLOEXEC for all internal files. The O_CLOEXEC flag should also be set when obtaining file handles from the V4L2 VIDIOC_EXPBUF operation, but was missed during the updates to both d942bdc913c5 ("libcamera: v4l2_device: openat(2) with O_CLOEXEC to cleanup after exec(3)") and 436b38fd89fe ("libcamera: Open files with O_CLOEXEC"). Set the O_CLOEXEC flag on calls to ioctl(VIDIOC_EXPBUF).

2023-05-04v4l2: Move the v4l2 compat layer to libexec/libcameraKieran Bingham
Move the v4l2-compat.so shared library installation to the libcamera directory under libexec. This is the same location that the proxy workers live and will facilitate easier packaging of the V4L2 compatibility layer with distributions. Create a new libcamera_libexecdir variable within meson to simplify representation of this path and update the proxy worker meson.build infrastructure to make use of it as well.

2023-05-04pipeline: raspberrypi: Introduce PipelineHandlerBase classNaushir Patuck
Create a new PipelineHandlerBase class that handles general purpose housekeeping duties for the Raspberry Pi pipeline handler. Code the implementation of new class is essentially pulled from the existing pipeline/rpi/vc4/raspberrypi.cpp file with a small amount of refactoring. Create a derived PipelineHandlerVc4 class from PipelineHandlerBase that handles the VC4 pipeline specific tasks of the pipeline handler. Again, code for this class implementation is taken from the existing pipeline/rpi/vc4/raspberrypi.cpp with a small amount of refactoring. The goal of this change is to allow third parties to implement their own pipeline handlers running on the Raspberry Pi without duplicating all of the pipeline handler housekeeping tasks.

Restructure the IPA mojom interface to be more consistent in the use of the API. Function parameters are now grouped into *Params structures and results are now returned in *Results structures. The following pipeline -> IPA interfaces have been removed: signalQueueRequest(libcamera.ControlList controls); signalIspPrepare(ISPConfig data); signalStatReady(uint32 bufferId, uint32 ipaContext); and replaced with: prepareIsp(PrepareParams params); processStats(ProcessParams params); signalQueueRequest() is now encompassed within prepareIsp().
