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.

2019-05-17test: v4l2_device: Switch most tests to vimcNiklas Söderlund
The vimc driver delivers frames much faster then the vivid driver hence most v4l2 device tests complete much quicker if vimc is used. The only v4l2 device test which can't be switched is buffer_sharing as it needs to import buffers somewhere, something vimc do not support. With this change I manage to shave of almost 7 seconds for each run of all v4l2 device tests.

This is needed to put the device under test into known state and not have the v4l2 device tests depend on that no one have touched the device before the test is executed. The resolution is picked purely at random and could possibly be moved to each test case if there is a need for different resolutions for a specific one.

To gain better control of when a file descriptor is open to the media device and reduce the work needed in pipeline handler implementations, handle the file descriptor in acquire() and release(). This changes the current behavior where a file descriptor is only open when requested by the pipeline handler to that one is always open as long a media device is acquired.

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.

2019-02-13libcamera: signal: Disconnect signal automatically on slot deletionLaurent Pinchart
When a signal is connected to a member function slot, the slot is not disconnected when the slot object is deleted. This can lead to calling a member function of a deleted object if the signal isn't disconnected manually by the slot object's destructor. Make signal handling easier by implementing a base Object class that tracks all connected signals and disconnects from them automatically when the object is deleted, using template specialization resolution in the Signal class. As inheriting from the Object class may to a too harsh requirement for Signal usage in applications, keep the existing behaviour working if the slot doesn't inherit from the Object class. We may reconsider this later and require all slot objects to inherit from the Object class.

2019-01-24libcamera: device_enumerator: Reference-count MediaDevice instancesLaurent Pinchart
The MediaDevice class will be the entry point to hot-unplug, as it corresponds to the kernel devices that will report device removal events. The class will signal media device disconnection to pipeline handlers, which will clean up resources as a result. This can't be performed synchronously as references may exist to the related Camera objects in applications. The MediaDevice object thus needs to be reference-counted in order to support unplugging, as otherwise pipeline handlers would be required to drop all the references to the media device they have borrowed synchronously with the disconnection signal handler, which would be very error prone (if even possible at all in a sane way).
