2024-10-25qcam: Automatically select the camera if only one is availableStanislaw Gruszka
When only a single camera is available, showing the camera selection dialog is unnecessary. It's better to automatically select the available camera without prompting the user for input.

2024-10-24libcamera: rkisp1: Plumb the dw100 dewarper as V4L2M2M converterUmang Jain
Plumb the dw100 dewarper as a V4L2M2M converter in the rkisp1 pipeline handler. If the dewarper is found, it is instantiated and buffers are exported from it, instead of RkISP1Path. Internal buffers are allocated for the RkISP1Path in case where dewarper is going to be used. The RKISP1 pipeline handler now supports scaler crop control through the converter. Register the ScalerCrop control for the cameras created in the RKISP1 pipeline handler.

2024-10-24libcamera: rkisp1: Prepare for additional camera controlsUmang Jain
Currently the rkisp1 pipeline handler only registers controls that are related to the IPA. This patch prepares the rkisp1 pipeline-handler to register camera controls which are not related to the IPA. Hence, introduce an additional ControlInfoMap for IPA controls. These controls will be merged together with the controls in the pipeline handler (introduced subsequently) as part of updateControls() and together will be registered during the registration of the camera. This is similar to what IPU3 pipeline handler handles its controls.

2024-10-24libcamera: converter: Add interface to support cropping capabilityUmang Jain
If the converter has cropping capability on its input, the interface should support it by providing appropriate virtual functions. Provide Feature::InputCrop in Feature enumeration for the same. Provide virtual setInputCrop() and inputCropBounds() interfaces so that the converter can implement its own cropping functionality. The V4L2M2MConverter implements these interfaces of the Converter interface. Not all V4L2M2M converters will have cropping ability on its input, hence it needs to be discovered at construction time. If the capability to crop is identified successfully, the cropping bounds are determined during configure() time.

2024-10-18libcamera: software_isp: Black level from tuning fileMilan Zamazal
This patch allows obtaining a black level from a tuning file in addition to the camera sensor helper. If both of them define a black level, the one from the tuning file takes precedence. The use cases are: - A user wants to use a different black level, for whatever reason. - There is a sensor without known gains but with a known black level. Because a camera sensor helper cannot be defined without specifying gains, the only way to specify the black level is using the tuning file.

2024-10-03libcamera: yaml_parser: Take string keys in `std::string_view`Barnabás Pőcze
In many cases a static string literal is used as key. Thus having the argument type be `const std::string&` is suboptimal since an `std::string` object needs to be constructed before the call. C++17 introduced `std::string_view`, using which the call can be done with less overhead, as the `std::string_view` is non-owning and may be passed in registers entirely. So make `YamlObject::{contains,operator[]}` take the string keys in `std::string_view`s. Unfortunately, that is not sufficient yet, because `std::map::find()` takes an reference to `const key_type`, which would be `const std::string&` in the case of `YamlParser`. However, with a transparent comparator such as `std::less<>` `std::map::find()` is able to accept any object as the argument, and it forwards it to the comparator. So make `YamlParser::dictionary_` use `std::less<>` as the comparator to enable the use of `std::map::find()` with any type of argument.

2024-09-30apps: cam: Print an error when outputting DNG and DNG support is missingLaurent Pinchart
When DNG support is missing, the cam application ignores the .dng suffix of the file pattern and writes raw binary data instead, without notifying the user. This leads to confusion. Fix it by printing an error message.

2024-09-30apps: Replace HAVE_DNG with HAVE_TIFFLaurent Pinchart
Support for DNG capture is conditioned by the availability of libtiff, which is indicated by the HAVE_TIFF macro set by meson. The dng_writer.h header then defines HAVE_DNG, which is used in a couple of places to conditionally compile DNG-related code. Most of the other locations where conditional compilation is required use HAVE_TIFF. Using both HAVE_TIFF and HAVE_DNG is confusing. HAVE_DNG would be a better name, but as the macro is defined in dng_writer.h, it would require all files that need to test for DNG support to include that header. Failure to include it (directly or indirectly) would result in the code covered by the macro to be silently disabled. To avoid the confusion, standardize on using HAVE_TIFF everywhere and drop HAVE_DNG.

2024-09-30pipeline: rkisp1: Filter out sensor sizes not supported by the pipelineUmang Jain
It is possible that the maximum sensor size (returned by CameraSensor::resolution()) is not supported by the pipeline. In such cases, a filter function is required to filter out resolutions of the camera sensor, which cannot be supported by the pipeline. Introduce the filter function filterSensorResolution() in RkISP1Path class and use it for validate() and generateConfiguration(). The maximum sensor resolution is picked from that filtered set of resolutions instead of CameraSensor::resolution().

2024-09-28libcamera: rkisp1: Eliminate hard-coded resizer limitsUmang Jain
The minResolution_ and maxResolution_ limits are dynamically queried in populateFormats() from the RkISP1Path video node. Therefore, initializing these limits with the resizer limits in the constructor is unnecessary. This change allows us to remove the hard-coded max/min resolution limits of the resizer from RkISP1Path, simplifying its constructor further.

2024-09-27pipeline: simple: Increase buffer count to fourRobert Mader
Which is not only what many other pipeline handlers use, but also a good lower limit when dealing with DRM and similar APIs. Even Mesas EGL and Vulkan WSI implementations use for the reason outlined in mesa commit 992a2dbba80aba35efe83202e1013bd6143f0dba: > When the compositor is directly scanning out from the application's buffer it > may end up holding on to three buffers. These are the one that is is currently > scanning out from, one that has been given to DRM as the next buffer to flip > to, and one that has been attached and will be given to DRM as soon as the > previous flip completes. When we attach a fourth buffer to the compositor it > should replace that third buffer so we should get a release event immediately > after that. This patch therefore also changes the number of buffer slots to 4 > so that we can accomodate that situation. Given the popularity of this buffer number the bump should be unlikely to cause problems. At the same time it may help with performance or even work around glitches. The previous number was introduced in commit a8964c28c80fb520ee3c7b10143371081d41405a without mentioning a specific reason against the change at hand.

The black level is likely to get updated, if ever, only after exposure or gain changes. Don't compute its possible updates if exposure and gain are unchanged. It's probably not worth trying to implement something more sophisticated. Better to spend the effort on supporting tuning files.
