2022-10-20qcam: Simplify dependency handling for libtiffLaurent Pinchart
There's no need to conditionally add tiff_dep to the list of qcam dependency, as a not found dependency() is ignored when listed in the executable dependencies argument.

2022-09-05qcam: Use QDialog for selection of cameras at startupUtkarsh Tiwari
Currently we use QInputDialog convenience dialogs to allow the user to select a camera. This doesn't allow adding of more information (such as camera location, model etc). Create a QDialog with a QFormLayout that shows a QComboBox with camera Ids. Use a QDialogButtonBox to provide buttons for accepting and cancelling the action. The CameraSelectorDialog is only initialized the first time when the MainWindow is created. From this commit we cease to auto select the camera if only a single camera is available to libcamera. We would always display the selection dialog with the exception being that being if the camera is supplied on the command line.

2020-12-01qcam: Make log less verbose by defaultLaurent Pinchart
The qcam log prints one message per frame, which is pretty verbose. This feature is useful for debugging, but not necessarily as a default option. Silence it by default, and add a -v/--verbose command line parameter to make the log verbose. While this could have been handled manually by checking a verbose flag when printing the message, the feature is instead integrated with the Qt log infrastructure to make it more flexible. Messages printed by qDebug() are now silenced by default and controlled by the -v/--verbose argument.

2020-05-13licenses: License all meson files under CC0-1.0Laurent Pinchart
In an attempt to clarify the license terms of all files in the libcamera project, the build system files deserve particular attention. While they describe how the binaries are created, they are not themselves transformed into any part of binary distributions of the software, and thus don't influence the copyright on the binary packages. They are however subject to copyright, and thus influence the distribution terms of the source packages. Most of the meson.build files would not meet the threshold of originality criteria required for copyright protection. Some of the more complex meson.build files may be eligible for copyright protection. To avoid any ambiguity and uncertainty, state our intent to not assert copyrights on the build system files by putting them in the public domain with the CC0-1.0 license.

2020-03-24qcam: viewfinder: Make the viewfinder hold a reference to a bufferLaurent Pinchart
The viewfinder is currently expected to render frames to the screen synchronously in the display() function, or at least to copy data so that the buffer can be queued in a new request when the function returns. This prevents optimisations when the capture format is identical to the display format. Make the viewfinder take ownership of the buffer, and notify of its release through a signal. The release is currently still synchronous, this will be addressed in a subsequent patch. Rename the ViewFinder::display() function to render() to better describe its purpose, as it's meant to start the rendering and not display the frame synchronously.

2020-03-24qcam: Remove custom event dispatcherLaurent Pinchart
The qcam application installs a custom event dispatcher based on the Qt event loop. As the camera manager now creates an internal thread, it doesn't use that event dispatcher of the application thread at all. Furthermore, the custom event dispatcher is buggy, as it doesn't dispatch messages posted to the main thread's event loop. This isn't an issue as no messages are posted there in the first place, but would cause incorrect behaviour if we were to use that feature (for instance to deliver signals from the camera manager thread to the application thread). Fixing the event dispatcher requires a change in the libcamera public API, as there's currently no way to dispatch messages using the public API (Thread::dispatchMessages() is not exposed). This isn't worth it at the moment, so just remove the custom event dispatcher. If qcam later needs the libcamera request and buffer completion signals to be delivered in the application thread, it will need to handle that internally, using Qt's cross-thread signal delivery.
