38 hourslibcamera: pipeline: vivid: Handle controlsKieran Bingham
When constructing the camera, we parse the available controls on the video capture device, and map supported controls to libcamera controls, and initialise the defaults. The controls are handled during queueRequestDevice for each request and applied to the device through the capture node. Signed-off-by: Kieran Bingham <kieran.bingham@ideasonboard.com>
38 hourslibcamera: pipeline: vivid: Initialise key controlsKieran Bingham
The VIVID pipeline handler retains state globally of it's controls. Ensure that when we configure this specific pipeline we set initial parameters on the device that suit our (specific) needs. This introduces how controls can be set directly on a device, however under normal circumstances controls should usually be set from libcamera controls as part of a request. These are VIVID specific only. Signed-off-by: Kieran Bingham <kieran.bingham@ideasonboard.com>
38 hourslibcamera: pipeline: vivid: Queue requestsKieran Bingham
When a request is given to a pipeline handler, it must parse the request and identify what actions the pipeline handler should take to enact on hardware. In the case of the VIVID pipeline handler, we identify the buffer from the only supported stream, and queue it to the video capture device.

38 hourslibcamera: pipeline: vivid: Buffer handling and stream controlKieran Bingham
We can now add buffer management, and connect up our bufferReady signal to a callback. Note that we provide the ability to export buffers from our capture device (data->video_) using the exportBuffers() functionality from the V4L2VideoDevice which allows a FrameBufferAllocater to obtain buffers from this device. When buffers are obtained through the exportFrameBuffers API, they are orphaned and left unassociated with the device, and must be reimported at start() time anyway. This allows the same interface to be used whether internal buffers, or external buffers are used for the stream. When a buffer completes, we call the buffer completion handler on the pipeline handler, and because we have only a single stream, we can also immediately complete the request.

38 hourslibcamera: pipeline: vivid: Configure the deviceKieran Bingham
When the configurations have been generated and validated, they can be applied to a device. Vivid supports only a single stream, so it directly obtains the first StreamConfiguration from the CameraConfiguration. The VIVID catpure device is a V4L2Video device, so we generate a V4L2DeviceFormat to apply directly to the capture device node. Note that we convert the libcamera Format stored in cfg.pixelFormat to a V4L2PixelFormat using V4L2PixelFormat helper. This currently defaults to the single-planar formats, and should be extended to support the Multiplanar configuration from the V4L2Device. [todo Repair the link between the multiplanar configuration of the V4L2VideoDevice and the pixel format selection] Following the call to set the format using the Kernel API, if the format has been adjusted in any way by the kernel driver, then we have failed to correctly handle the validation stages, and thus the configure operation is idendified has having failed. Finally stream specific data can be directly stored and set as reflecting the state of the stream. [NOTE: the cfg.setStream() call here associates the stream to the StreamConfiguration however that should quite likely be done as part of the validation process. TBD] Signed-off-by: Kieran Bingham <kieran.bingham@ideasonboard.com>

6 daysmeson: Convert `v4l2` into a feature optionBarnabás Pőcze
The v4l2 compatibility layer does not have external dependencies, the usual benefits of a feature option do not apply. The main motivation behind this change is making use of the `auto_features` meson option that can change all feature options set to "auto" by default to the desired value. This can be useful for two reasons: (1) using auto_features=disabled and then building up the list of features that are desired in the particular build; (2) using auto_features=enabled to achieve (usually) more testing and compilation coverage.

10 dayslibcamera: virtual: Speed up test pattern animationBarnabás Pőcze
After the initial generation, when a frame is requested, the test pattern generator rotates the image left by 1 column. The current approach has two shortcomings: (1) it allocates a temporary buffer to hold one column; (2) it swaps two columns at a time. The test patterns are simple ARGB images, in row-major order, so doing (2) works against memory prefetching. This can be addressed by doing the rotation one row at a time as that way the image is addressed in a purely linear fashion. Doing so also eliminates the need for a dynamically allocated temporary buffer, as the required buffer now only needs to hold one sample, which is 4 bytes in this case. In an optimized build, this results in about a 2x increase in the number of frames per second as reported by `cam`. In an unoptimized, ASAN and UBSAN intrumented build, the difference is even bigger, which is useful for running lc-compliance in CI in a reasonable time.

2024-12-23libcamera v0.4.0Kieran Bingham
The abi-compliance-checker reports that there is both ABI and API breakage in this release. Binary compatibility: 91.2% Source compatibility: 98.9% Total binary compatibility problems: 69, warnings: 0 Total source compatibility problems: 9, warnings: 0 This is not too surprising as this was the reason for the extra delay holding up this release, and as such this release bumps the SONAME to 0.4 accordingly. The majority of the ABI breakages are around the public API for Control handling and definitions, which have caused underlying identifiers to be changed, and the reuqired storage for controls has increased. I hope that grouping the expected ABI and API breakages and delaying this release will allow a longer stability on the 0.4 series but as we are developing rapidly this can not be guaranteed, though we aim to minimise disruption to distributions and applications whereever possible. This release brings in 253 commits, with substantial development on image control and tuning features for IPA and Pipeline handlers supporting libipa, as well as integrating libipa support for IPA handling on the ARM Mali-C55 ISP. A new 'Virtual Pipeline Handler' has been introduced to support more testing in CI and virtual environments. Gstreamer has had some interesting development to rework expressing the full control set from libcamera using auto generation from the full control descriptors. A key and notable change in this release too is that the softISP is now moving towards utilising the libipa implementaitons which will enable future tuning and image control capabilities, and should also support future development on a GPU-ISP implementation for GPU-accelerated handling. I do believe this work may have introduced an oscillation regression in the AEGC which will need to be investigated and fixed in the near future, but I don't want to hold up progressing the ABI updates at this stage. The i.MX8MP can now make full use of the DW100 Dewarp Engine for full rotation and digital zoom capabilities. Raspberry Pi systems now have improved support for the OV7251, IMX462, and IMX327 Sensors, and libipa platforms can now make use of the GalaxyCore gc05a2 and gc08a3 Image sensors.

2024-12-20ipa: rpi: awb: Make it possible to set the colour temperature directlyDavid Plowman
ColourTemperature is now exported as a writable control so that applications can set it directly. The AWB algorithm class now requires a method to be provided to perform this operation. The method should clamp the passed value to the calibrated range known to the algorithm. The default range is set very wide to cover all conceivable future AWB calibrations. It will always be clamped before use.

2024-12-20ipa: rkisp1: awb: Implement ColourTemperature controlStefan Klug
There are many use-cases (tuning-validation, working in static environments) where a manual ColourTemperature control is helpful. Implement that by interpolating and applying the white balance gains from the tuning file according to the requested colour temperature. If colour gains are provided on the same request, they take precedence. Store the colour temperature used for a given frame in the frame context and report that in metadata. Note that in the automatic case, the colour gains are still based on the gray world model and the CT curve from the tuning file get ignored.
