2019-07-14libcamera: v4l2_videodevice: Signal buffer completion at streamoff timeLaurent Pinchart
When stopping the stream buffers have been queued, in which case their completion is never be notified to the user. This can lead to memory leaks. Fix it by notifying completion of all queued buffers with the status set to error. As a result the base PipelineHandler implementation can be simplified, as all requests complete as the result of stopping the stream. The stop() method that manually completes all queued requests isn't needed anymore.

2019-07-14libcamera: v4l2_videodevice: Add helper to queue all buffersLaurent Pinchart
When starting the stream on a capture video device it is often needed to queue all the allocated buffers. Add a helper method to do so, and refactor the existing queueBuffer() method to make it clearer.

2019-07-13test: v4l2_videodevice: buffer_sharing: Lower resolution to speed up testLaurent Pinchart
Lower the resolution to the smallest vivid supports, 320x180, in order to speed up the test. This isn't enough in itself as the frame rate also has to be configured, but the V4L2VideoDevice class doesn't support frame rate control yet. In the meantime the frame rate can be set manually with yavta or v4l2-ctl. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Reviewed-by: Paul Elder <paul.elder@ideasonboard.com>
2019-06-19libcamera: Rename V4L2Device to V4L2VideoDeviceJacopo Mondi
In preparation of creating a new V4L2Device base class, rename V4L2Device to V4L2VideoDevice. This is a project wide rename without any intended functional change.
