2023-04-20libcamera: controls: guard ControlInfoMap against nullptr idmap_Mattijs Korpershoek
It's possible to construct a Camera with an unsafe controlInfo_. This is the case in the Simple pipeline, where the camera controls are not populated. With Simple, if we attempt to set a Control, we end up with a segfault because the default constructor for ControlInfoMap doesn't intialized idmap_ which is initialized at class declaration time as const ControlIdMap *idmap_ = nullptr; Add some safeguards in ControlInfoMap to handle this case.

2023-04-19libcamera: device_enumerator_udev: Use std::string_viewBarnabás Pőcze
In `udevNotify()`, constructing an std::string from the device's associated action is unnecessary as it is only compared against static strings, and for that purpose an std::string_view works just as well, while being cheaper to construct. In the same vein, an std::string_view can be used to store the device's devnode initially, and the string construction can be deferred until it is needed. Furthermore, previously `udev_device_get_devnode()` was called twice. The extra call is now removed.

Previously, after `addV4L2Device()` had seen all dependecies, it would remove the `MediaDeviceDeps` object from the `pending_` list, which would result in it being destroyed. However, there would still be (dangling) pointers to this object in `devMap_` that were added in `addUdevDevice()` (line 103). So remove the entry with the given devnum when it is removed from the corresponding `MediaDeviceDeps` object.

2023-03-21py: cam: Fix demosaic overflow issueTomi Valkeinen
The demosaic code first expands the buffer datatype to uint16, and then shifts the data left so that the 8, 10 and 12 bitspp formats all become 16 bitspp. It then, eventually, uses np.einsum to calculate averages, but this averaging sums multiple uint16 values together, and stores them in uint16 storage. As in the first step we shifted the values left, possibly getting values close to the maximum of uint16 range, we, of course, overflow when summing them together. This leads to rather bad looking images. Fix this by dropping the original shift. It serves no purpose, and is probably a remnant of some early testing code. This way the largest numbers we are summing together are 12 bit values, and as we use a 3x3 window from which we fetch values, for a single rgb plane, the max number of 12 bit values is 5 (for green). Sum of 5 12 bit values is well below the 16 bit maximum.

Add a new parameter to the pipeline handler config file named "unicam_timeout_value_ms" to allow users to override the automatically computed Unicam timeout value. This value is given in milliseconds, and setting a value of 0 (the default value) disables the override. An example use of this parameter would be if an application configured a RAW stream, and provides buffers for the stream on every request. If the application holds off on sending requests for a particular reason (e.g. a timelapse use case), then we will possibly hit the watchdog timeout as it is only a small multiple of the frame length. This override allows an application to select a larger value with the knowledge that it may space requests longer than the calculated timeout value.

2023-03-07ipa: raspberrypi: Better heuristics for calculating Unicam timeoutNaushir Patuck
The existing mechanism of setting a timeout value simply uses the maximum possible frame length advertised by the sensor mode. This can be problematic when, for example, the IMX477 sensor can use a frame length of over 600 seconds. However, for typical usage the frame length will never go over several 100s of milliseconds, making the timeout very impractical. Store a list of the last 10 frame length values requested by the AGC. On startup, and at the end of every frame, take the maximum frame length value from this list and return that to the pipeline handler through the setCameraTimeoutValue() signal. This allows the timeout value to better track the actual sensor usage.

2023-03-06libcamera: camera_manager: Stop exponential explosive calls to ↵Sophie Friedrich
createPipelineHandlers Currently the function `createPipelineHandlers` connects itself to the `devicesAdded` signal at the end of each call. As the Signal object supports multiple non-unique listeners connected to it, the former function would be called exponentially often with each new emitted event on `devicesAdded` (i.e. with udev plugging in a new camera) Fix it by connecting the createPipelineHandlers() slot to `devicesAdded` signal in CameraManager::Private::init() instead. This will prevent the slot getting connected multiple times to the `devicesAdded` signal.

2023-03-01libcamera: Keep using syslog for isolated IPA modulesMatthias Fend
Currently it is not possible to display debug output from an isolated IPA module. The standard descriptors are all closed and any specified log file is explicitly deactivated for the IPA module. Since libcamera and the isolated IPA module are separate processes, they cannot write to the same file. However, if syslog is used, then this would be possible. If syslog is specified as a log file, then this is left as it is for the isolated IPA module.

Commit 613d5402673e ("pipeline: raspberrypi: Fix handling of colour spaces") adjusts the colorspace to ColorSpace::Raw for raw streams. However, if the colorspace is not requested for raw streams(nullopt), we should still set the colorspace to ColorSpace::Raw, for raw streams.
