2020-02-14qcam: Move requestCompleted signal mappingKieran Bingham
The MainWindow connects a handler to the Camera requestCompleted signal when the camera is opened, but never disconnects it. Move the connection to the startCapture() function, and ensure that it is disconnected again when the stream is stopped. This ensures that we can successfully tear down the stream, and restart with a new camera. Introducing the error_disconnect cleanup path in start_capture identified that we left the camera in the start state, thus we also add a call to camera->stop() when disconnecting the signal connection.

2020-02-13libcamera: camera: Implement the threading modelLaurent Pinchart
Document the threading model of the Camera class and implement it. Selected functions become thread-safe, and require a few functions of the PipelineHandler class to be called through cross-thread invocation as the pipeline handlers live in the camera manager thread, while the Camera class is mostly accessed from the application thread. The PipelineHandler is made to inherit from the Object class to support this. Disconnection is currently left out as it is not implemented in pipeline handlers, and isn't fully supported in the Camera class either. This will be revisited when implementing proper hotplug support. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Reviewed-by: Niklas Söderlund <niklas.soderlund@ragnatech.se>
2020-02-13libcamera: camera_manager: Run the camera manager in a threadLaurent Pinchart
Relying on the application event loop to process all our internal events is a bad idea for multiple reasons. In many cases the user of libcamera can't provide an event loop, for instance when running through one of the adaptation layers. The Android camera HAL and V4L2 compatibility layer create a thread for this reason, and the GStreamer element would need to do so as well. Furthermore, relying on the application event loop pushes libcamera's realtime constraints to the application, which isn't manageable. For these reasons it's desirable to always run the camera manager, the pipeline handlers and the cameras in a separate thread. Doing so isn't too complicated, it only involves creating the thread internally when starting the camera manager, and synchronizing a few methods of the Camera class. Do so as a first step towards defining the threading model of libcamera. The event dispatcher interface is still exposed to applications, to enable cross-thread signal delivery if desired.
