2024-05-16ipa: rpi: Add HDR supportNaushir Patuck
Add support for the following HDR modes in the Raspberry Pi IPA: - Night mode - Single exposure mode - Multi-exposure (merged and unmerged) The algorithm is updated to expect the HDR short channel to meter explicitly for highlights. This means that it will not in general under-expose the short channel more than is actually necessary. When images don't have much saturation, it's good to detect this so that some of the boost we want to apply to the dark areas can be implemented as regular gain. This means we can then adjust the tone curve less, leading to less flat looking images. The impact on the HDR algorithm is then that this determines how we build tonemaps dynamically. The highlights are more-or-less correct now, so we have to build a power-type curve that gives us the appropriately configured targets in the lower part of the histogram. We allow the tuning file to supply the maximum spatial gain value, rather than the whole curve (though it can supply this if it wants). Some parameter defaults are tweaked to be generally better across the range of our cameras.

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.

2024-05-13test: gstreamer: Simplify single stream testNicolas Dufresne
The single stream test for the GStreamer component has a simple pipeline construction using only a fakesink. The implementation currently supports connecting to a more complex stream construction defined by the streamDescription, but this is over engineered for the simple need to start a stream to capture and discard the frames. Convert the use of gst_parse_bin_from_description_full() which uses only a single element 'fakesink' to construct the fakesink directly and link it to the libcamerasrc.

Commit 1dc01bc9e6c3 ("ipa: libipa: histogram: Add transform parameter to constructor") added a new constructor for the Histogram class. The implementation is inline in the header file, and the documentation was added in the corresponding .cpp file, but it missed the \fn directive. This causes Doxygen to complain: src/ipa/libipa/histogram.h:31: warning: Member Histogram(Span< const uint32_t > data, Transform transform) (function) of class libcamera::ipa::Histogram is not documented. src/ipa/libipa/histogram.cpp:59: warning: libcamera::ipa::Histogram::bins has @param documentation sections but no arguments Fix it.

Source files in libcamera start by a comment block header, which includes the file name and a one-line description of the file contents. While the latter is useful to get a quick overview of the file contents at a glance, the former is mostly a source of inconvenience. The name in the comments can easily get out of sync with the file name when files are renamed, and copy & paste during development have often lead to incorrect names being used to start with. Readers of the source code are expected to know which file they're looking it.

2024-05-09ipa: libipa: histogram: Add transform parameter to constructorPaul Elder
Add a parameter to the histogram constructor that takes a transformation function to apply to all the bins upon construction. This is necessary notably for the rkisp1, as the values reported from the hardware are 20 bits where the upper 16-bits are meaningful integer values and the lower 4 bits are fractional and meant to be discarded. As adding a right-shift parameter is probably too specialized, a generic function is added as a parameter instead. While at it, optimize the existing constructor to avoid push_back() into a vector with a known final size.

2024-05-07test: Don't add current build directory to include pathLaurent Pinchart
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. We could work around the problem by renaming the test executable, but disabling the implicit inclusion of the local directory is a more generic solution that will avoid similar issues in the future.
