2019-07-17libcamera: qcam: Allow specifying sizes on command lineJacopo Mondi
Add a '-s|--size' option to qcam to allow selecting the stream resolution using a command line option. If the sizes are not supported by the camera, they get automatically adjusted and the user notified via an output message.

2019-07-14libcamera: buffer: Add an accessor to the BufferMemoryLaurent Pinchart
Buffer instances reference memory, which is modelled internally by a BufferMemory instance. Store a pointer to the BufferMemory in the Buffer class, and populate it when the buffer is queued to the camera through a request. This is useful for applications to access the buffer memory in the buffer or request completion handler.

2019-07-14libcamera: buffer: Split memory information to BufferMemoryLaurent Pinchart
The Buffer class is a large beast the stores information about the buffer memory, dynamic metadata related to the frame stored in the buffer, and buffer reference data (in the index). In order to implement buffer import we will need to extend this with dmabuf file descriptors, making usage of the class even more complex. Refactor the Buffer class by splitting the buffer memory information to a BufferMemory class, and repurposing the Buffer class to reference a buffer and to store dynamic metadata. The BufferMemory class becomes a long term storage, valid and stable from the time buffer memory is allocated to the time it is freed. The Buffer class, on the other hand, becomes transient, is created on demand when an application requires a buffer, is given to a request, and is deleted when the request completes. Buffer and BufferMemory don't need to be copied, so their copy constructor and assignment operators are deleted.

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: 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.

2019-03-29qcam: 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.
