In this case the controls were removed from the source maps on the first call to updateControls() and on the second call to updateControls() they were missing in the source maps and therefore also removed from the camera.

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.

2024-05-08libcamera: Drop file name from header comment blocksLaurent Pinchart
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. Drop the file name from the header comment block. The change was generated with the following script: ---------------------------------------- dirs="include/libcamera src test utils" declare -rA patterns=( ['c']=' \* ' ['cpp']=' \* ' ['h']=' \* ' ['py']='# ' ['sh']='# ' ) for ext in ${!patterns[@]} ; do files=$(for dir in $dirs ; do find $dir -name "*.${ext}" ; done) pattern=${patterns[${ext}]} for file in $files ; do name=$(basename ${file}) sed -i "s/^\(${pattern}\)${name} - /\1/" "$file" done done ---------------------------------------- This misses several files that are out of sync with the comment block header.

2022-11-25ipa: rkisp1: Support raw capture in IPA operationsLaurent Pinchart
The RkISP1 can capture raw frames by bypassing the ISP. In that mode, the ISP will not produce statistics nor consume parameters. Most algorithms will thus be unable to run, with one exception: the AGC will still be able to configure the sensor exposure time and analog gain in manual mode. To prepare for this, add the ability to disable algorithms for the duration of the capture session based on the camera configuration. Individual algorithms report whether they support raw formats at construction time, and the IPA module disables algorithms in configure() based on the stream configurations. Disabled algorithms are skipped during the capture session in the processStatsBuffer() operation. As the ISP doesn't produce statistics, don't try to access the stats buffer. There is no need for similar logic in fillParamsBuffer() as that operation won't be called for raw capture. All algorithms report not supporting raw capture by default. Raw support in AGC will be added separately. The feature is implemented in the RkISP1 module without any support from libipa at this point to avoid designing a generic API based on a single user. This may be changed in the future.

The RkISP1 pipeline and IPA module allows for the CameraSensorInfo to be empty, probably to accommodate some sensor used in a test platform that does not provide the mandatory libcamera requirements. As the \todo item in the IPA reports, there is a possibility that the received CameraSensorInfo is empty and it should be checked before accessing it, but currently such requirement is not enforced in the code. This allows to assume all the test platforms in use have now successfully moved their sensor driver to comply with the minimum requirements and provide a populated CameraSensorInfo to the IPA.

The limits for the shutter speed and analogue gain are stored in IPASessionConfiguration::agc. While they're related to the AGC, they are properties of the sensor, and are stored in the session configuration by the IPA module, not the AGC algorithm. Move them to the IPASessionConfiguration::sensor structure where they belong.

Reorder functions in the base ipa::Algorithm and its derived classes to match the calling order: queueRequest(), prepare() and process(). This makes the code flow easier to read. No functional change intended. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Reviewed-by: Paul Elder <paul.elder@ideasonboard.com> Reviewed-by: Jacopo Mondi <jacopo@jmondi.org>

LSC gradient parameters are currently computed during prepare() phase. Because these parameters can be computed only one time and stay constant for each frame after, move the computation to the configure() function.

2022-10-24ipa: Pass metadata to Algorithm::process() functionLaurent Pinchart
Extend the Algorithm::process() function with a metadata control list, to be filled by individual algorithms with frame metadata. Update the rkisp1 and ipu3 IPA modules accordingly, and drop the dead code in the IPARkISP1::prepareMetadata() function while at it. This only creates the infrastructure, filling metadata in individual algorithms will be handled separately.
