2023-11-29build: controls: Rework how controls and properties are generatedNaushir Patuck
Add support for using separate YAML files for controls and properties generation. The mapping of vendor/pipeline handler to control file is done through the controls_map variable in include/libcamera/meson.build. This simplifies management of vendor control definitions and avoids possible merge conflicts when changing the control_ids.yaml file for core and draft controls. With this change, libcamera and draft controls and properties files are designated the 'libcamera' vendor tag. In this change, we also rename control_ids.yaml -> control_ids_core.yaml and property_ids.yaml -> property_ids_core.yaml to designate these as core libcamera controls.

2023-11-25Documentation: Add code of conductLaurent Pinchart
Communities have standards regarding behaviours they consider acceptable or not acceptable, and expect community members to follow those standards. libcamera is no different, even if it has never clearly expressed those standards in a formal code of conduct document. Like software licenses, codes of conduct can be written in a myriad of ways. And like software licenses, using a widely adopted code of conduct instead of writing our own can help bringing clarity. One such standard code of conduct is the Contributor Covenant, stewarded by the Organization for Ethical Source. The Contributor Covenant has been adopted by the freedesktop.org organization, which hosts a large number of projects historically related to graphics, and more recently to multimedia in general. freedesktop.org offers services such as git hosting with CI, which libcamera could benefit from. There is therefore a clear incentive to choose the same code of conduct as freedesktop.org, and no known drawback. As a first step towards this, and to keep the libcamera code of conduct history clear in git, copy the original Contributor Covenant v1.4 from https://github.com/EthicalSource/contributor_covenant/. "v1.4" is ambiguous as the document initially published as v1.4 has received small (but sometimes significant) modifications over time. The version imported here ([1]) is the most recent "v1.4", from tags/2.1 (commit 8a3be1350b07 "Merge pull request #979 from JustArchi/patch-2").

2023-07-04libcamera: camera: Take span of StreamRole instead of vectorBarnabás Pőcze
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.

2022-11-23libcamera: Move IPA sensor controls validation to CameraSensorJacopo Mondi
The CameraSensor class validates that the sensor driver in use supports the controls required for IPA modules to work correctly. For in-tree IPA modules, whose pipeline handlers already use CameraSensor there's no need to validate such controls again. Remove controls validation from the IPU3 and RkISP1 IPA modules and rely on CameraSensor doing that at initialization time. The list of mandatory controls is expanded to add V4L2_CID_ANALOGUE_GAIN without which IPA modules cannot function. The new requirement only applies to RAW sensors, platforms like UVC and Simple are not impacted by this change. While at it, expand the sensor driver requirements documentation to include V4L2_ANALOGUE_GAIN in the list of mandatory controls a sensor driver has to support.

2022-10-13meson: Shared Object version handlingKieran Bingham
The libcamera project is not yet ready to declare ABI nor API stability, but it will benefit the community to be able to provide more regular release cycles to determine 'versioned' points of history. Ideally, these releases will be made at any ABI breakage, but can be made at arbitary time based points along the way. To support releases which may not be ABI stable, declare the soversion of both the libcamera and libcamera-base library to be dependant upon both the major minor and patch component of the project version. As part of this, introduce a new 'Versions' summary section to highlight the different version components that may become apparent within any given build. Bumping versions may leave dangling libcamera.so.* symlinks in build directories. This will confuse Doxygen which will print during its directory scanning phase a warning that the symlink can't be read. As we don't need Doxygen to follow symlinks, disable it with EXCLUDE_SYMLINKS.

2022-08-31Documentation: Strip default options and comments from Doxyfile.inLaurent Pinchart
Doxyfile.in was generated using `doxygen -g` with Doxygen v1.8.14. This has produced a file with all options supported by Doxygen at the time, and a handful of them have then been modified to support libcamera's needs, with most options retaining their default. Some of the default options have been deprecated in newer Doxygen releases, which led to warnings when generating the documentation. The usual process to fix this is to update the configuration file with `doxygen -u`. This creates a big diff due to the large number of changes to default options, which isn't quite nice. Instead, let's just drop all the default options and the comments, to produce a small and more readable Doxyfile.in.

2022-08-03libcamera: v4l2_videodevice: Reintroduce toV4L2PixelFormat()Jacopo Mondi
This is a partial revert of commit 395d43d6d75b ("libcamera: v4l2_videodevice: Drop toV4L2PixelFormat()") The function was removed because it incorrectly maps non-contiguous V4L2 format variants (ie V4L2_PIX_FMT_YUV420M) to the API version supported by the video device (singleplanar API and multiplanar API). It was decided at the time to remove the function and let its users call directly V4L2PixelFormat::fromPixelFormat() which accepts a 'multiplanar' flags. As we aim to associate multiple V4L2PixelFormat to a single libcamera format, the next patches will verify which of them is actually supported by the video device. For now, return the contiguous version unconditionally. Re-introduce V4L2VideoDevice::toV4L2PixelFormat() and convert all the V4L2PixelFormat::fromPixelFormat() users to use it. The V4L2 compatibility layer is the only outlier as it doesn't have a video device to poke, hence it still uses V4L2PixelFormat::fromPixelFormat(). Next patches will implement the device format matching logic and handle the non-contiguous plane issue in V4L2VideoDevice::toV4L2PixelFormat().
