2023-09-25pipeline: rpi: Reset the frame lengths queue during configureNaushir Patuck
The IPA stores a list of the last 10 frame lengths applied to the sensor for determining the timeout to use. This list gets reset on start(), but there is a path through the code that accesses this list in configure() which happens earlier, causing a logical error. Fix this by constructing the list with 10 initial values of 0s.

A channel constraint is somewhat similar to the upper/lower bound constraints that we use elsewhere, but these constraints apply between multiple AGC channels. For example, it lets you say things like "don't let the channel 1 total exposure be more than 8x that of channel 0", and so on. By using both an upper and lower bound constraint, you could fix one AGC channel always to be a fixed ratio of another. Also read a vector of them (if present) when loading the tuning file.

2023-09-16ipa: rpi: agc: Implementation of multi-channel AGCDavid Plowman
The switchMode, prepare and process methods are updated to implement multi-channel AGC correctly: * switchMode now invokes switchMode on all the channels (whether active or not). * prepare must find what channel the current frame is, and run on behalf of that channel. * process updates the most recent DeviceStatus and statistics for the channel of the frame that has just arrived, but generates updated values working through the active channels in round-robin fashion. One minor detail in process is that we don't want to change the DeviceStatus metadata of the current frame, so we now pass this to the AgcChannel's process method, rather than letting it find the DeviceStatus in the metadata.

2023-09-16ipa: rpi: agc: Reorganise code for multi-channel AGCDavid Plowman
This commit does the basic reorganisation of the code in order to implement multi-channel AGC. The main changes are: * The previous Agc class (in agc.cpp) has become the AgcChannel class in (agc_channel.cpp). * A new Agc class is introduced which is a wrapper round a number of AgcChannels. * The basic plumbing from ipa_base.cpp to Agc is updated to include a channel number. All the existing controls are hardwired to talk directly to channel 0. There are a couple of limitations which we expect to apply to multi-channel AGC. We're not allowing different frame durations to be applied to the channels, nor are we allowing separate metering modes. To be fair, supporting these things is not impossible, but there are reasons why it may be tricky so they remain "TBD" for now. This patch only includes the basic reorganisation and plumbing. It does not yet update the important methods (switchMode, prepare and process) to implement multi-channel AGC properly. This will appear in a subsequent commit. For now, these functions are hard-coded just to use channel 0, thereby preserving the existing behaviour.

2023-06-19pipeline: rpi: Do not return an error from pipeline config file handlingNaushir Patuck
If a user provided pipeline config file is not present, or if the version reported in the file is invalid, do not return with an error when creating the pipeline handler. Instead, log a warning message and return success with default pipeline config values used. This now matches the behaviour when the pipeline config file could not be parsed correctly, and we revert to default values.

2023-06-19ipa: rpi: agc: Do not switch to a default if a mode is unavailableNaushir Patuck
In commit 0ee9339331c6, a default metering/exposure/constraint mode is used if a control sets a mode that is not listed in the camera tuning file. Setting a default mode may be undesirable in these cases, so instead keep the agc mode unchanged. This also matches the behaviour for other IPA controls where no changes are made in error conditions.

2023-06-19libcamera: camera_sensor: Adjust properties::RotationJacopo Mondi
As the CameraSensor::validateTransform() function compensate for the sensor's mounting rotation, the properties::Rotation value should be adjusted to make sure application that receive already "corrected" images do not get confused by Rotation still reporting a value. Howerver, as an image sensor can only compensate rotations by applying H/V flips, only correct Rotation when the mounting rotation is 180 degrees.

2023-06-18gstreamer: Add enable_auto_focus option to the GStreamer pluginCedric Nugteren
Cameras such as the PiCam 3 support auto-focus, but the GStreamer plugin for libcamera does not enable auto-focus. With this patch auto-focus can be enabled for cameras that support it. By default it is disabled, which means default behaviour remains unchanged. For cameras that do not support auto-focus, an error message shows up if auto-focus is enabled. This was tested on cameras that do not support auto-focus (e.g. PiCam2) and was tested on a camera that does support auto-focus (PiCam3). The test involved setting the focus to AfModeContinous and observing it. However, by not setting "auto-focus-mode" or using AfModeManual as the "auto-focus-mode" both resulting in auto-focus being disabled.

2023-06-17libcamera: pipeline: Register device numbers with cameraKieran Bingham
Register the identified device numbers with each camera as the SystemDevices property. This facilitates camera daemons or other systems to identify which devices are being managed by libcamera, and can prevent duplication of camera resources. As the SystemDevices property now provides this list of devices, use it directly from within the CameraManager when adding a Camera rather than passing it through the internal API.
