2019-02-13test: v4l2_device: release capture device resourcesKieran Bingham
Ensure that the cleanup operation releases the device and resources. Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Signed-off-by: Kieran Bingham <kieran.bingham@ideasonboard.com>
2019-02-13test: v4l2_device: Rename dev_ to capture_Kieran Bingham
Change the variable name globally throughout the tests. Repair the V4L2DeviceTest constructor style, as checkstyle complained. Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Signed-off-by: Kieran Bingham <kieran.bingham@ideasonboard.com>
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.

2019-02-13test: v4l2_device: Use VIVID capture streamKieran Bingham
Utilise the VIVID capture device for testing the V4L2Device objects. Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Signed-off-by: Kieran Bingham <kieran.bingham@ideasonboard.com>
2019-02-06test: v4l2_device: Provide asynchronous capture testKieran Bingham
Utilise the event_dispatcher to create a default event loop, and process asynchronous buffer receive events. If no frames are captured in 5 seconds, the test will fail. It will also fail if less than 30 frames have been captured in the same timeout period.
