2022-08-08cam: sdl_sink: Fix compilation with SDL2 <2.0.16Laurent Pinchart
The SDL_UpdateNVTexture() function, used for NV12 texture support, has been introduced in SDL2 2.0.16. Compiling against older SDL versions fails with ../src/cam/sdl_texture_yuv.cpp: In member function ‘virtual void SDLTextureNV12::update(const std::vector<libcamera::Span<const unsigned char> >&)’: ../src/cam/sdl_texture_yuv.cpp:19:2: error: ‘SDL_UpdateNVTexture’ was not declared in this scope; did you mean ‘SDL_UpdateYUVTexture’? 19 | SDL_UpdateNVTexture(ptr_, &rect_, data[0].data(), pitch_, | ^~~~~~~~~~~~~~~~~~~ | SDL_UpdateYUVTexture Fix it with conditional compilation based on the SDL version.

2022-08-08cam: sdl_sink: Add NV12 texture supportLaurent Pinchart
Extend the SDL sink with support for NV12 textures, useful on platforms that don't support packed YUYV formats.

2022-08-08cam: sdl_sink: Support multi-planar formatsLaurent Pinchart
In order to prepare for NV12 support, implement support for multi-planar formats in the SDL sink. This mainly consists in passing a vector of plane data to the SDLTexture::update() function instead of a single value.

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.
