2020-05-13licenses: License all meson files under CC0-1.0Laurent Pinchart
In an attempt to clarify the license terms of all files in the libcamera project, the build system files deserve particular attention. While they describe how the binaries are created, they are not themselves transformed into any part of binary distributions of the software, and thus don't influence the copyright on the binary packages. They are however subject to copyright, and thus influence the distribution terms of the source packages. Most of the meson.build files would not meet the threshold of originality criteria required for copyright protection. Some of the more complex meson.build files may be eligible for copyright protection. To avoid any ambiguity and uncertainty, state our intent to not assert copyrights on the build system files by putting them in the public domain with the CC0-1.0 license.

2020-03-19libcamera: geometry: Construct SizeRange from SizeLaurent Pinchart
The SizeRange constructors take minimum and maximum width and height values as separate arguments. We have a Size class to convey size information, use it in the constructors, and update the callers.

2020-03-18libcamera: PixelFormat: Make constructor explicitLaurent Pinchart
To achieve the goal of preventing unwanted conversion between a DRM and a V4L2 FourCC, make the PixelFormat constructor that takes an integer value explicit. All users of pixel formats flagged by the compiler are fixed.

The IPA, IPC and Stream tests are self-contained so they can run in parallel. Signed-off-by: Niklas Söderlund <niklas.soderlund@ragnatech.se> Reviewed-by: Kieran Bingham <kieran.bingham@ideasonboard.com> Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
2019-06-19test: stream: Add test for StreamFormatNiklas Söderlund
Test that both discrete and range based stream format descriptions result in good discrete frame sizes. The range based stream formats needs to be fitted with a table of resolutions inside libcamera so if that table is updated this test might need to be updated.
