2023-11-25Documentation: Add code of conductLaurent Pinchart
Communities have standards regarding behaviours they consider acceptable or not acceptable, and expect community members to follow those standards. libcamera is no different, even if it has never clearly expressed those standards in a formal code of conduct document. Like software licenses, codes of conduct can be written in a myriad of ways. And like software licenses, using a widely adopted code of conduct instead of writing our own can help bringing clarity. One such standard code of conduct is the Contributor Covenant, stewarded by the Organization for Ethical Source. The Contributor Covenant has been adopted by the freedesktop.org organization, which hosts a large number of projects historically related to graphics, and more recently to multimedia in general. freedesktop.org offers services such as git hosting with CI, which libcamera could benefit from. There is therefore a clear incentive to choose the same code of conduct as freedesktop.org, and no known drawback. As a first step towards this, and to keep the libcamera code of conduct history clear in git, copy the original Contributor Covenant v1.4 from https://github.com/EthicalSource/contributor_covenant/. "v1.4" is ambiguous as the document initially published as v1.4 has received small (but sometimes significant) modifications over time. The version imported here ([1]) is the most recent "v1.4", from tags/2.1 (commit 8a3be1350b07 "Merge pull request #979 from JustArchi/patch-2").

2023-11-22gstreamer: Implement element EOS handlingJaslo Ziska
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.

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.

If the pipeline runs out of embedded data buffers, then it will pass the frame to the IPA without the metadata. The IPA then has to use the delayed controls as inputs to the algorithms. This can cause problems with the subsequent algorithms if the sensor did not action the controls, especially with the autofocus as that doesn't have controls which can be passed in lieu of the metadata.

2023-10-18ipa: rpi: Add statsInline to the Controller hardware descriptionNaushir Patuck
Add a new boolean field (statsInline) to Controller::HardwareConfigMap. This field indicates where the statistics are generated in the hardware ISP pipeline. For statsInline == true, statistics are generated before the frame is processed (e.g. the PiSP case), and statsInline == false indicates statistics are generated after the frame is processed (e.g. the VC4 case).

Add the PiSP Frontend and Backend SharedMemObject file descriptors to the ipa::init() call. This will allow the pipeline handler to pass these objects to the IPA after construction. Add a flag to indicate if buffer swaps are needed when starting the ISP for the stitch block.

2023-10-18ipa: rpi: Add IpaBase::platformStart() member functionNaushir Patuck
Add a virtual IpaBase::platformStart() member function that is called at the end of IpaBase::start(). For the IpaVc4 derived class, this function does nothing, but will be used in the PiSP derived class to reset internal state on startup.
