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.

2019-04-03qcam: meson: Use pkg-config method for qt5 dependenciesKieran Bingham
Meson searches for qmake to determine if QT5 is available to support the optional qcam component. When cross compiling, meson can incorrectly identify the host qmake which will cause incorrect linkage and usage of system headers. Set the dependency method to specify pkg-config which resolves the issue.

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.
