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.

2019-05-23meson: Create and use a dependency for libcamera and its headersLaurent Pinchart
Instead of manually adding the libcamera library and include path to every target that requires it, declare a dependency that groups the headers as source, the library and the include path, and use it through the project. This simplifies handling of the dependency. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Reviewed-by: Kieran Bingham <kieran.bingham@ideasonboard.com>

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.

2019-05-17test: v4l2_device: Reset media links and set a resolutionNiklas Söderlund
When initializing the test reset any media links and set a know resolutions. 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.

2019-02-13libcamera: v4l2_device: Simplify exportBuffers()Kieran Bingham
exportBuffers() can only operate on an existing BufferPool allocation. The pool identifies its size through its .count() method. Passing a count in to the exportBuffers() call is redundant and can be incorrect if the value is not the same as the BufferPool size. Simplify the function and remove the unnecessary argument, correcting all uses throughout the code base. While we're here, remove the createBuffers() helper from the V4L2DeviceTest which only served to obfuscate which pool the buffers were being allocated for.

2019-02-13test: v4l2_device: capture_async: End test at 30 framesKieran Bingham
The capture_async test was written to run for a fixed 5 second duration. Modify the test such that it runs until it has captured 30 frames, or a 10 second time out occurs. Running the capture_async test on an ARM64 platform using VIVID captures 30 frames in 6.15 seconds. There may be scope to optimise this speed by changing the format on the capture device.
