2022-08-08cam: Rename sdl_texture_yuyv.{cpp,h} to sdl_texture_yuv.{cpp,h}Laurent Pinchart
In preparation for the addition of NV12 support in the SDL sink, rename the sdl_texture_yuyv.{cpp,h} files to just "yuv". Separate sdl_texture_nv12.{cpp,h} files could be added instead, but given how short the implementation will be, grouping all YUV formats in a single file is better.

2022-07-28cam: sdl_sink: Use libjpeg over SDL2_imageEric Curtin
We were using the libjpeg functionality of SDL2_image only, instead just use libjpeg directly to reduce our dependancy count, it is a more commonly available library.

2022-05-23cam: sdl_sink: Add MJPG support to SDL sinkEric Curtin
So we have at least two supported capturing pixel formats (although many possible output pixel formats thanks to SDL conversion). MJPG support only built in if SDL2_image is available, provides decompression.

2022-05-23cam: sdl_sink: Add SDL sink with initial YUYV supportEric Curtin
This adds more portability to existing cam sinks. You can pass a YUYV camera buffer and SDL will handle the pixel buffer conversion to the display. This allows cam reference implementation to display images on VMs, Mac M1, Raspberry Pi, etc. This also enables cam reference implementation, to run as a desktop application in Wayland or X11. SDL also has support for Android and ChromeOS which has not been tested. Also tested on simpledrm Raspberry Pi 4 framebuffer successfully where existing kms sink did not work. Can also be used as kmsdrm sink. Only supports one camera stream at present.

2022-05-22cam: Add a parser for capture scriptsJacopo Mondi
Add a parser class to the cam test application to control the capture operations through a yaml script. The capture script currently allow to specify a list of controls and their associated values to be applied per-frame. Also add a trivial capture script example to showcase the intended script structure.

2021-09-07cam: Add Image classLaurent Pinchart
The new Image class represents a multi-planar image with direct access to pixel data. It currently duplicates the function of the MappedFrameBuffer class which is internal to libcamera, and will serve as a design playground to improve the API until it is considered ready to be made part of the libcamera public API.

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.
