2019-07-04qcam: Update window title with FPSKieran Bingham
Provide an average FPS in the QCam title bar to show the current rate of frame processing. The QCam compilation is updated to process the Qt MoC headers to support signals and slots accordingly.

2019-07-04qcam: Add the version string to the titleKieran Bingham
Provide the version string reported by the libcamera library on the qcam test utility. This helps confirm the exact version of the library that is being used while testing. The version string is stored in the MainWindow so that it can be reused without reconstructing.

The 'last' buffer timestamp is stored as a static. Rename the variable to a more descritive 'lastBufferTime' and move it to the class instance. Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Signed-off-by: Kieran Bingham <kieran.bingham@ideasonboard.com>
2019-05-23libcamera: camera: Return a pointer from generateConfiguration()Laurent Pinchart
To prepare for specialising the CameraConfiguration class in pipeline handlers, return a pointer to a camera configuration instead of a reference from Camera::generateConfiguration(). The camera configuration always needs to be allocated from the pipeline handler, and its ownership is passed to the application. For symmetry, change Camera::configure() to take a CameraConfiguration pointer instead of a reference. This aligns with our coding practice of passing parameters that are modified by the callee by pointer.

2019-05-23libcamera: Refactor the camera configuration storage and APILaurent Pinchart
Refactor the CameraConfiguration structure to not rely on Stream instances. This is a step towards making the camera configuration object more powerful with configuration validation using "try" semantics. The CameraConfiguration now exposes a simple vector-like API to access the contained stream configurations. Both operator[]() and at() are provided to access elements. The isEmpty() method is renamed to empty() and the methods reordered to match the std::vector class. As applications need access to the Stream instances associated with the configuration entries in order to associate buffers with streams when creating requests, expose the stream selected by the pipeline handler through a new StreamConfiguration::stream().

2019-05-23libcamera: Use stream roles directly instead of StreamUsageLaurent Pinchart
In order to prepare for an API overhall of the camera configuration generation, remove the StreamUsage class and replace its uses by stream roles. The size hints can't be specified anymore, and will be replaced with an API on the StreamConfiguration to negotiate configuration parameters with cameras.

2019-05-23libcamera: camera: Rename configureStreams() and streamConfiguration()Laurent Pinchart
Rename the configureStreams() and streamConfiguration() methods to configure() and generateConfiguration() respectively in order to clarify the API. Both methods deal with CameraConfiguration objects, and are thus not limited to streams, even if a CameraConfiguration currently contains streams only. While at it, remove the qcam MainWindow::configureStreams() method that is declared but never defined or used.

2019-04-05libcamera: camera: Add support for stream usagesNiklas Söderlund
Instead of requesting the default configuration for a set of streams where the application has to figure out which streams provided by the camera is best suited for its intended usage, have the library figure this out by using stream usages. The application asks the library for a list of streams and a suggested default configuration for them by supplying a list of stream usages. Once the list is retrieved the application can fine-tune the returned configuration and then try to apply it to the camera. Currently no pipeline handler is prepared to handle stream usages but nor did it make use of the list of Stream IDs which was the previous interface. The main reason for this is that all cameras currently only provide one stream each. This will still be the case but the API will be prepared to expand both pipeline handlers and applications to support streams usages.

2019-03-29qcam: Add Qt-based GUI applicationLaurent Pinchart
qcam is a sample camera GUI application based on Qt. It demonstrates integration of the Qt event loop with libcamera. The application lets the user select a camera through the GUI, and then captures a single stream from the camera and displays it in a window. Only streams in YUYV formats are supported for now.
