2024-05-14libcamera: camera_manager: Add environment variable to order pipelines matchJulien Vuillaumier
To match the enumerated media devices, each registered pipeline handler is used in no specific order. It is a limitation when several pipelines can match the devices, and user has to select a specific pipeline. For this purpose, environment variable LIBCAMERA_PIPELINES_MATCH_LIST is created to give the option to define an ordered list of pipelines to match on.

2024-05-14libcamera: pipeline: Rename pipelines to a shorter nameJulien Vuillaumier
The PipelineHandlerFactoryBase class has a name that is propagated to the PipelineHandler instance it creates. In present implementation, this name comes from the REGISTER_PIPELINE_HANDLER registration macro. It corresponds to the stringified name of the PipelineHandler derived class. Therefore, PipelineHandler factories and instances names can be quite long such as "PipelineHandlerRkISP1". A libcamera user may have to explicitly refer to a PipelineHandler name for configuration purpose: one usage of the name can be to define a pipeline handlers match list and their priorities. It is desired, for user convenience, to use a short name to designate a pipeline handler. Reusing the short pipeline names already defined in the meson option files is an existing and consistent way of naming pipelines. This change adds an explicit name parameter to the REGISTER_PIPELINE_HANDLER registration macro. That parameter is used to define the name of a pipeline handler factory, instead of the current pipeline handler class name. Each pipeline registration is updated accordingly. The short name assigned corresponds to the pipeline directory name in the source tree. It is consistent with pipelines names used in meson. Changing the pipeline name has an impact on the IPA modules: each module defines a IPAModuleInfo structure. This structure has a pipelineName member defining the pipeline handler name it shall match with. Therefore, each internal IPA module definition has to be changed to have its IPAModuleInfo pipelineName name updated with the short pipeline handler name. In addition to this pipelineName member, the IPAModuleInfo structure also has a name member, associated to the IPA module name. Having renamed the pipelines to a short name, the pipeline name and the IPA module names of the IPAModuleInfo structure are the same: for in-tree IPA, they correspond to the respective pipeline and IPA subdirectories in the source tree. However the IPA name could be different, for instance with a close source IPA implementation built out-of-tree. Thus, it makes sense to keep the IPA name in that structure, as the 2 definitions may not always be redundant.

The camera name is copied in gst_libcamera_src_open() as we can't hold the lock protecting the name while calling GST_ELEMENT_ERROR().

2024-05-14Documentation: Add option to treat Doxygen warnings as errorsLaurent Pinchart
A new Doxygen warning introduced in a recent commit went unnoticed, both in manual tests and in CI. Unlike C/C++ warnings that are treated as errors, we don't fail the build with Doxygen warnings. This is due to the fact that the libcamera documentation compiles cleanly only with quite recent versions of Doxygen. Enabling the WARN_AS_ERROR Doxygen option unconditionally could bother many users. To improve the situation, add a meson option to treat Doxygen warnings as errors. The option is disabled by default, preserving the current behaviour, and will be enabled in CI builds.

Meson adds the current source and build directory to the include path by default. This causes a namespace clash in tests when using C++20, as the Span class test is compiled into a binary named 'span', which then gets included by source code through indirect '#include <span>' directives. Unsurprisingly, the compiler doesn't react happily when fed binary data.

2024-04-20android: camera_device: Always clear descriptors_ in stop()Anle Pan
When flush() is called and then a new stream configuration is set, the descriptors_ queue might have a chance to be not cleared in stop(), as the Camera is already in Stopped state. This will prevent further requests from being completed in sendCaptureResults() as the descriptors_ queue is not empty. To fix the issue, clear the descriptors_ even if the Camera State is Stopped. As a drawback the libcamera::Camera::stop() function might be called twice, but this is allowed by the Camera state machine, and the second call is guaranteed to be a nop.

2024-04-17ipu3: Use posix basenameKhem Raj
musl does not implement GNU basename extention and with latest musl the prototype from string.h is also removed [1] which now results in compile errors e.g. ../git/utils/ipu3/ipu3-pack.c:21:47: error: call to undeclared function 'basename'; ISO C99 and later do not support implicit function declarations [-Wimplicit-function-declaration] These utilities are using this function in usage() which is used just before program exit. Always use the basename APIs from libgen.h which is posix implementation [1] https://git.musl-libc.org/cgit/musl/commit/?id=725e17ed6dff4d0cd22487bb64470881e86a92e7 Signed-off-by: Khem Raj <raj.khem@gmail.com> Reviewed-by: Kieran Bingham <kieran.bingham@ideasonboard.com> Signed-off-by: Kieran Bingham <kieran.bingham@ideasonboard.com>
2024-04-16libcamera: software_isp: Apply black level compensationMilan Zamazal
Black may not be represented as 0 pixel value for given hardware, it may be higher. If this is not compensated then various problems may occur such as low contrast or suboptimal exposure. The black pixel value can be either retrieved from a tuning file for the given hardware, or automatically on the fly. The former is the right and correct method, while the latter can be used when a tuning file is not available for the given hardware. Since there is currently no support for tuning files in software ISP, the automatic, hardware independent way, is always used. Support for tuning files should be added in future but it will require more work than this patch. The patch looks at the image histogram and assumes that black starts when pixel values start occurring on the left. A certain amount of the darkest pixels is ignored; it doesn't matter whether they represent various kinds of noise or are real, they are better to omit in any case to make the image looking better. It also doesn't matter whether the darkest pixels occur around the supposed black level or are spread between 0 and the black level, the difference is not important. An arbitrary threshold of 2% darkest pixels is applied; there is no magic about that value. The patch assumes that the black values for different colors are the same and doesn't attempt any other non-primitive enhancements. It cannot completely replace tuning files and simplicity, while providing visible benefit, is its goal. Anything more sophisticated is left for future patches. A possible cheap enhancement, if needed, could be setting exposure + gain to minimum values temporarily, before setting the black level. In theory, the black level should be fixed but it may not be reached in all images. For this reason, the patch updates black level only if the observed value is lower than the current one; it should be never increased. The purpose of the patch is to compensate for hardware properties. General image contrast enhancements are out of scope of this patch. Stats are still gathered as an uncorrected histogram, to avoid any confusion and to represent the raw image data. Exposure must be determined after the black level correction -- it has no influence on the sub-black area and must be correct after applying the black level correction. The granularity of the histogram is increased from 16 to 64 to provide a better precision (there is no theory behind either of those numbers).
