2019-02-06libcamera: Add Buffer ManagementKieran Bingham
Provide classes that represent frame buffers and pools of frame buffers. An image within the system may use one or more Plane objects to track each plane in the case of multi-planar image formats. The Buffer class manages all of the data required to render or interpret the raw image data.

2019-02-01libcamera: stream: add initial Stream classNiklas Söderlund
Add an initial Stream implementation. The idea is that once capability support is added to the library each stream will describe its capabilities using this class. An application will then select one or more streams based on these capabilities and use them to configure the camera and capture. At this stage the Stream class is empty as capabilities are yet to be added. The class is still useful as it will be used to communicate how many streams a Camera object provides.

2019-01-08libcamera: Add a poll-based event dispatcherLaurent Pinchart
Provide a poll-based event dispatcher implementation as convenience for applications that don't need a custom event loop. The poll-based dispatcher is automatically instantiated if the application doesn't provide its own dispatcher. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
2019-01-08libcamera: Add event notification infrastructureLaurent Pinchart
Add three new classes, EventDispatcher, EventNotifier and Timer, that define APIs for file descriptor event notification and timers. The implementation of the EventDispatcher is meant to be provided to libcamera by the application. The event dispatcher is integrated twith the camera manager to implement automatic registration of timers and events.

2019-01-08libcamera: Add signal/slot communication mechanismLaurent Pinchart
Introduce a Signal class that allows connecting event sources (signals) to event listeners (slots) without adding any boilerplate code usually associated with the observer or listener design patterns.

2019-01-02libcamera: Remove libcamera classLaurent Pinchart
The class was just a placeholder, now that we have other objects defined, remove it along with the associated test. The libcamera/libcamera.h header is kept as a shortcut to include the whole libcamera public API. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
2018-12-31libcamera: Add MediaDevice classJacopo Mondi
The MediaDevice object implements handling and configuration of the media graph associated with a media device. The class allows enumeration of all pads, links and entities registered in the media graph.

2018-12-31libcamera: Add MediaObject class hierarchyJacopo Mondi
Add a class hierarcy to represent all media objects a media graph represents. Add a base MediaObject class, which retains the global unique object id, and define the derived MediaEntity, MediaLink and MediaPad classes. This hierarchy will be used by the MediaDevice objects which represents and handles the media graph.

2018-12-31libcamera: device_enumerator: add DeviceInfo classNiklas Söderlund
Provide a DeviceInfo class which holds all information from the initial enumeration of a media device. Not all information available at a media device is stored, only the information needed for a pipeline handler to find a specific device.

2018-12-31libcamera: add dependency on libudevNiklas Söderlund
The device enumeration will depend on libudev, add the dependency to the build system. This should be turned into a optional dependency once a device enumerator not using udev is supported.

2018-12-31libcamera: Add Camera classNiklas Söderlund

2018-12-19build: Define library private include pathJacopo Mondi
Separate declaration of library internal inclusion path. This will be used by tests, developed outside of library code, that need to include parts of the library internal APIs and can re-use the here defined variable.

2018-12-11build: Clean up file names variablesLaurent Pinchart
The build system defines two variables, public_api and sources, that store the names of the public headers and the source files respectively. These files will need to be referenced when generating documentation from source code, so let's make the variable names more descriptive: - Rename public_api to libcamera_api and use the files() function - Rename sources to libcamera_sources - Add a libcamera_headers variable to hold the internal headers Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
2018-12-06libcamera: Add initial loggerLaurent Pinchart
The logger is based on the ostream API, allowing code to log messages in a native way. It automatically logs the time stamp, severity level, file name and line number. Many important features are missing, such as logging to file, logging classes, and log filtering based on the severity level, file name and class.

2018-12-06Overhaul the directory structureLaurent Pinchart
In order to match the directory structure of traditional projects, rename the top-level lib/ directory to src/libcamera/. Other libraries developed as part of the project will later find a home in src/. Split the libcamera header files in three categories: public headers describing the public API in include/libcamera/, internal headers describing the internal API in src/libcamera/include/, and private headers local to one or a small number of compilation units along the corresponding .cpp files. As no internal header exists yet the src/libcamera/include/ directory is created empty as the build system would fail otherwise.
