2024-01-09libcamera: framebuffer_allocator: Remove unnecessary `clear()`Barnabás Pőcze
The vector in question is destroyed when the item in the `buffers_` map is destroyed as a result of the `erase()` call. A vector's destructor already does all the things that `clear()` does, so calling it earlier is not needed.

2023-12-08meson: Replace hack with usage of '@BASENAME@'Laurent Pinchart
Starting with meson 0.59, the custom_target() function substitutes '@BASENAME@' in the output parameter with the input file name, with the extension removed. This is exactly what we implement manually when generating the IPA interface .cpp files. Furthermore, starting with meson 0.60, the 'name' positional parameter to the custom_target() function is optional, and defaults to the basename of the output file (including the extension). This is exactly the name we compute manually and pass to the function. As libcamera requires meson 0.60 or newer, we can depend on those two features and drop manual computation of the base name. This fixes a warning with recent meson versions that complain that passing a file object to the format() function is a broken feature: WARNING: Broken features used: * 1.3.0: {'str.format: Value other than strings, integers, bools, options, dictionaries and lists thereof.'} Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Reviewed-by: Kieran Bingham <kieran.bingham@ideasonboard.com>
2023-12-07meson: Tag all installed filesLaurent Pinchart
Meson uses tags to sort installed files in categories, and makes it possible to install a subset of the files using the '--tags' argument to 'meson install'. This is typically used by distributions to split the runtime, development and documentation files into separate packages. By default, meson tries to guess the correct tag for installed files, but can't always do so properly. Mark the install targets that meson can't guess with the correct install_tag. As the feature has been introduced in meson 0.60, bump the minimum meson version. The latest LTS release of all major distributions that libcamera currently targets ship a recent enough meson version.

2023-12-07gstreamer: Implement renegotiationJaslo Ziska
This commit implements renegotiation of the camera configuration and source pad caps. A renegotiation can happen when a downstream element decides to change caps or the pipeline is dynamically changed. To handle a renegotiation the GST_FLOW_NOT_NEGOTIATED return value has to be handled in GstLibcameraSrcState::processRequest(). Otherwise the default would be to print an error and stop streaming. To archive this in a clean way the if statement is altered into a switch statement which now also has a case for GST_FLOW_NOT_NEGOTIATED. In the case of GST_FLOW_NOT_NEGOTIATED every source pad is checked for the reconfiguration flag with gst_pad_needs_reconfigure() which does not clear this flag. If at least one pad requested a reconfiguration the function returns without an error and the renegotiation will happen later in the running task. If no pad requested a reconfiguration then the function will return with an error. In gst_libcamera_src_task_run() the source pads are checked for the reconfigure flag by calling gst_pad_check_reconfigure() and if one pad returns true and the caps are not sufficient anymore then the negotiation is triggered. It is fine to trigger the negotiation after only a single pad returns true for gst_pad_check_reconfigure() because the reconfigure flags are cleared in the gst_libcamera_src_negotiate() function. If any pad requested a reconfiguration the following will happen: 1. The camera is stopped because changing the configuration may not happen while running. 2. The completedRequests queue will be cleared by calling GstLibcameraSrcState::clearRequests() because the completed buffers have the wrong configuration. 3. The new caps are negotiated by calling gst_libcamera_src_negotiate(). When the negotiation fails streaming will stop. 4. The camera is started again.

We make a few small improvements to the code: * The arrayToSet method is prevented from overwriting the end of the array if there are too many values in the input table. If you supply a table, it will force you to put the correct number of elements in it. * The arrayToSet and setStrength member functions are turned into static functions. (There may be a different public setStrength member function in future.) * When no tables at all are given, the configuration is flagged as being disabled, so that we can avoid copying tables full of zeroes around. As a consequence, the pipeline handler too will disable this hardware block rather than run it needlessly. (Note that the tuning tool will put in a completely empty "rpi.cac" block if no CAC tuning images are supplied, benefiting from this behaviour.) * The initialise member function is removed as it does nothing.

2023-11-30libcamera: controls: Use vendor tags for draft controls and propertiesNaushir Patuck
Label draft controls and properties through the "draft" vendor tag and deprecate the existing "draft: true" mechanism. This uses the new vendor tags mechanism to place draft controls in the same libcamera::controls::draft namespace and provide a defined control id range for these controls. This requires moving all draft controls from control_ids.yaml to control_ids_draft.yaml. One breaking change in this commit is that draft control ids also move to the libcamera::controls::draft namespace from the existing libcamera::controls namespace. This is desirable to avoid API breakages when adding new libcamera controls. So, for example, the use of controls::NOISE_REDUCTION_MODE will need to be replaced with controls::draft::NOISE_REDUCTION_MODE.

Similarly, a ControlIdMap control is generated in the libcamera::controls::rpi namespace. A #define LIBCAMERA_HAS_RPI_VENDOR_CONTROLS is also generated to allow applications to conditionally compile code if the specific vendor controls are present. For the python bindings, the control is available with libcamera.controls.rpi.MyExampleControl. The above controls example applies similarly to properties. Existing libcamera controls defined in control_ids.yaml are given the "libcamera" vendor tag. A new --mode flag is added to gen-controls.py to specify the mode of operation, either 'controls' or 'properties' to allow the code generator to correctly set the #define string.

This commit implements EOS handling for events sent to the libcamerasrc element by the send_event method (which can happen when pressing Ctrl-C while running gst-launch-1.0 -e, see below). EOS events from downstream elements returning GST_FLOW_EOS are not considered here. To archive this add a function for the send_event method which handles the GST_EVENT_EOS event. This function will set an atomic to the received event and push this EOS event to all source pads in the running task. Also set the GST_ELEMENT_FLAG_SOURCE flag to identify libcamerasrc as a source element which enables it to receive EOS events sent to the (pipeline) bin containing it. This in turn enables libcamerasrc to receive EOS events, for example, from gst-launch-1.0 with the -e (--eos-on-shutdown) flag applied.

Perform check against availability of the control prior to usage in order to avoid the crash.

2023-11-06pipeline: rpi: vc4: Fix drop frame bug when no ISP streams are configuredNaushir Patuck
If no ISP output streams are configured, the ISP output count is skipped for the the low res stream, and causes the drop frame logic to fail because of a count mismatch. This in-turn stops any requests from completing correctly. Fix this by ensuring the low res output is counted correctly when no ISP output streams are configured.

2023-11-06libcamera: controls: Add controls for HDRDavid Plowman
We add an HdrMode control (to enable and disable HDR processing) and an HdrChannel, which indicates what kind of HDR frame (short, long or medium) has just arrived. Currently the HdrMode supports the following values: * Off - no HDR processing at all. * MultiExposureUnmerged - frames at multiple different exposures are produced, but not merged together. They are returned "as is". * MultiExposure - frames at multiple different exposures are merged to create HDR images. * SingleExposure - multiple frames all at the same exposure are merged to create HDR images. * Night - multiple frames will be combined to create "night mode" images.

We need to be able to do things like enable/disable AGC for all the channels, so most of the AGC controls are updated to be applied to all channels. There are a couple of exceptions, such as setting explicit shutter/gain values, which apply only to channel 0.

AWB writes this out during prepare, so we may as well read it in AGC prepare as well. Reading it in process is wrong on the PiSP platform because process runs before prepare, so the AWB status won't be there (on vc4 it made no difference).

"Fast desaturation" is a technique that can help the AGC algorithm to desaturate images more quickly when they are very over-exposed. However, it uses digital gain to do this which can confuse our HDR techniques. Therefore make it optional.
