2024-01-09build: controls: Add Raspberry Pi vendor specific controlsNaushir Patuck
Add a new control_ids_rpi.yaml file to hold the Raspberry Pi specific vendor controls. Define a control StatsOutputEnable to allow the ISP hardware statistics to be output through metadata via the Bcm2835StatsOutput control. The implementation of these controls will follow in a subsequent patch.

The gst_clear_event() function used by libcamerasrc has been introduced in GStreamer 1.16, while libcamera claims to need 1.14 or newer. This causes a compilation error. Fix it by copying the gst_clear_event() implementation to gstlibcamera-utils.h when compiling with older GStreamer version. The version check makes it clear that the workaround is needed with older versions only, flagging it for removal when the minimum GStreamer version requirement will be bumped.

When compiling with gcc 8.4.0, the compiler was reported to throw an unused variable warning: ../src/libcamera/camera.cpp: In member function ‘libcamera::CameraConfiguration::Status libcamera::CameraConfiguration::validateColorSpaces(libcamera::CameraConfiguration::ColorSpaceFlags)’: ../src/libcamera/camera.cpp:497:19: error: unused variable ‘i’ [-Werror=unused-variable] for (auto [i, cfg] : utils::enumerate(config_)) { ^ The build environment may have been incorrect as the problem couldn't be reproduced with gcc 8.3.0 and 8.5.0.

2023-12-08meson: Replace hack with usage of '@BASENAME@'Laurent Pinchart
Starting with meson 0.59, the custom_target() function substitutes '@BASENAME@' in the output parameter with the input file name, with the extension removed. This is exactly what we implement manually when generating the IPA interface .cpp files. Furthermore, starting with meson 0.60, the 'name' positional parameter to the custom_target() function is optional, and defaults to the basename of the output file (including the extension). This is exactly the name we compute manually and pass to the function. As libcamera requires meson 0.60 or newer, we can depend on those two features and drop manual computation of the base name. This fixes a warning with recent meson versions that complain that passing a file object to the format() function is a broken feature: WARNING: Broken features used: * 1.3.0: {'str.format: Value other than strings, integers, bools, options, dictionaries and lists thereof.'} Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Reviewed-by: Kieran Bingham <kieran.bingham@ideasonboard.com>
2023-12-07meson: Tag all installed filesLaurent Pinchart
Meson uses tags to sort installed files in categories, and makes it possible to install a subset of the files using the '--tags' argument to 'meson install'. This is typically used by distributions to split the runtime, development and documentation files into separate packages. By default, meson tries to guess the correct tag for installed files, but can't always do so properly. Mark the install targets that meson can't guess with the correct install_tag. As the feature has been introduced in meson 0.60, bump the minimum meson version. The latest LTS release of all major distributions that libcamera currently targets ship a recent enough meson version.

2023-12-07gstreamer: Implement renegotiationJaslo Ziska
This commit implements renegotiation of the camera configuration and source pad caps. A renegotiation can happen when a downstream element decides to change caps or the pipeline is dynamically changed. To handle a renegotiation the GST_FLOW_NOT_NEGOTIATED return value has to be handled in GstLibcameraSrcState::processRequest(). Otherwise the default would be to print an error and stop streaming. To archive this in a clean way the if statement is altered into a switch statement which now also has a case for GST_FLOW_NOT_NEGOTIATED. In the case of GST_FLOW_NOT_NEGOTIATED every source pad is checked for the reconfiguration flag with gst_pad_needs_reconfigure() which does not clear this flag. If at least one pad requested a reconfiguration the function returns without an error and the renegotiation will happen later in the running task. If no pad requested a reconfiguration then the function will return with an error. In gst_libcamera_src_task_run() the source pads are checked for the reconfigure flag by calling gst_pad_check_reconfigure() and if one pad returns true and the caps are not sufficient anymore then the negotiation is triggered. It is fine to trigger the negotiation after only a single pad returns true for gst_pad_check_reconfigure() because the reconfigure flags are cleared in the gst_libcamera_src_negotiate() function. If any pad requested a reconfiguration the following will happen: 1. The camera is stopped because changing the configuration may not happen while running. 2. The completedRequests queue will be cleared by calling GstLibcameraSrcState::clearRequests() because the completed buffers have the wrong configuration. 3. The new caps are negotiated by calling gst_libcamera_src_negotiate(). When the negotiation fails streaming will stop. 4. The camera is started again.

2023-11-30ipa: rpi: cac: Minor code improvements and tidyingDavid Plowman
We make a few small improvements to the code: * The arrayToSet method is prevented from overwriting the end of the array if there are too many values in the input table. If you supply a table, it will force you to put the correct number of elements in it. * The arrayToSet and setStrength member functions are turned into static functions. (There may be a different public setStrength member function in future.) * When no tables at all are given, the configuration is flagged as being disabled, so that we can avoid copying tables full of zeroes around. As a consequence, the pipeline handler too will disable this hardware block rather than run it needlessly. (Note that the tuning tool will put in a completely empty "rpi.cac" block if no CAC tuning images are supplied, benefiting from this behaviour.) * The initialise member function is removed as it does nothing.

2023-11-30libcamera: controls: Use vendor tags for draft controls and propertiesNaushir Patuck
Label draft controls and properties through the "draft" vendor tag and deprecate the existing "draft: true" mechanism. This uses the new vendor tags mechanism to place draft controls in the same libcamera::controls::draft namespace and provide a defined control id range for these controls. This requires moving all draft controls from control_ids.yaml to control_ids_draft.yaml. One breaking change in this commit is that draft control ids also move to the libcamera::controls::draft namespace from the existing libcamera::controls namespace. This is desirable to avoid API breakages when adding new libcamera controls. So, for example, the use of controls::NOISE_REDUCTION_MODE will need to be replaced with controls::draft::NOISE_REDUCTION_MODE.

Add support for vendor-specific controls and properties to libcamera. The controls/properties are defined by a "vendor" tag in the YAML control description file, for example: vendor: rpi controls: - MyExampleControl: type: string description: | Test for libcamera vendor-specific controls. This will now generate a control id in the libcamera::controls::rpi namespace, ensuring no id conflict between different vendors, core or draft libcamera controls. Similarly, a ControlIdMap control is generated in the libcamera::controls::rpi namespace. A #define LIBCAMERA_HAS_RPI_VENDOR_CONTROLS is also generated to allow applications to conditionally compile code if the specific vendor controls are present. For the python bindings, the control is available with libcamera.controls.rpi.MyExampleControl. The above controls example applies similarly to properties. Existing libcamera controls defined in control_ids.yaml are given the "libcamera" vendor tag. A new --mode flag is added to gen-controls.py to specify the mode of operation, either 'controls' or 'properties' to allow the code generator to correctly set the #define string. As a drive-by, sort and redefine the output command line argument in gen-controls.py and gen-py-controls.py to ('--output', '-o') for consistency.

This commit implements EOS handling for events sent to the libcamerasrc element by the send_event method (which can happen when pressing Ctrl-C while running gst-launch-1.0 -e, see below). EOS events from downstream elements returning GST_FLOW_EOS are not considered here. To archive this add a function for the send_event method which handles the GST_EVENT_EOS event. This function will set an atomic to the received event and push this EOS event to all source pads in the running task. Also set the GST_ELEMENT_FLAG_SOURCE flag to identify libcamerasrc as a source element which enables it to receive EOS events sent to the (pipeline) bin containing it. This in turn enables libcamerasrc to receive EOS events, for example, from gst-launch-1.0 with the -e (--eos-on-shutdown) flag applied.

Supported values are the ones obtained by applying flips to the camera sensor: - rot0: no rotation - rot180: rotate 180 degrees - flip: vertical flip - mirror: horizontal flip Signed-off-by: Jacopo Mondi <jacopo.mondi@ideasonboard.com> Reviewed-by: David Plowman <david.plowman@raspberrypi.com> Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
2023-10-23libcamera: Use CameraConfiguration::orientationJacopo Mondi
Replace the usage of CameraConfiguration::transform with the newly introduced CameraConfiguration::orientation. Rework and rename the CameraSensor::validateTransform(transform) to CameraSensor::computeTransform(orientation), that given the desired image orientation computes the Transform that pipeline handlers should apply to the sensor to obtain it. Port all pipeline handlers to use the newly introduced function. This commit breaks existing applications as it removes the public CameraConfiguration::transform in favour of CameraConfiguration::orientation.

2023-10-23libcamera: transform: Add operations with OrientationJacopo Mondi
Add two operations that allows to combine Transform with Orientation. - Transform operator/(const Orientation &o1, const Orientation &o2) allows to easily get back the Transform that needs to be applied to Orientation2 to get Orientation1 - Orientation operator*(const Orientation &o, const Transform &t) allows to apply a Transform to an Orientation and obtain the combination of the two These two operations allow applications to use Transforms to manipulate the Orientation inside the CameraConfiguration, if they wish.

2023-10-23libcamera: transform: Invert operator*() operandsJacopo Mondi
The current definition of operator*(Transform t1, Transform t0) follows the function composition notion, where t0 is applied first then t1 is applied last. In order to introduce operator*(Orientation, Transform) where a Transform is applied on top of an Orientation, invert the operand order of operator*(Transform, Transform) so that usage of operator* with both Orientation and Transform can be made associative. For example: Orientation o; Transform t = t1 * t2 Orientation o1 = o * t = o * (t1 * t2) = (o * t1) * t2 = o * t1 * t2 Signed-off-by: Jacopo Mondi <jacopo.mondi@ideasonboard.com> Reviewed-by: David Plowman <david.plowman@raspberrypi.com> Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>

2023-10-23libcamera: properties: Make 'Rotation' the mounting rotationJacopo Mondi
Specify in the documentation that properties::Rotation specifies the mounting rotation of the camera module. This avoids confusion with the image orientation which is instead expressed by CameraConfiguration::orientation. For this reason, do not compensate the Rotation property when initializing the CameraSensor class but report the value of V4L2_CID_CAMERA_SENSOR_ROTATION or 0 if the control is not available.

2023-10-23libcamera: camera: Introduce OrientationJacopo Mondi
Introduce the Orientation enumeration which describes the possible 2D transformations that can be applied to an image using two basic plane transformations. Add to the CameraConfiguration class a new member 'orientation' which is used to specify the image orientation in the memory buffers delivered to applications. The enumeration values follow the ones defined by the EXIF specification at revision 2.32, Tag 274 'orientation'. The newly introduced field is meant to replace CameraConfiguration::transform which is not removed yet not to break compilation.
