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.

2022-08-08cam: sdl_texture_yuyv: Make line stride configurableLaurent Pinchart
The line stride of the texture is currently hardcoded based on the image width, which may not match the real stride. Use the stride value from the stream configuration instead.

2022-07-28cam: sdl_sink: Pass a Span<const uint8_t> to SDLTexture::update()Laurent Pinchart
The SDLTexture::update() function isn't meant to modify the data it receives. Make the Span type const to ensure this at compile time. While at it, pass the Span by value instead of reference, as a Span is only a pointer and size, which will fit in registers and will avoid pointer dereferences in the callee.

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.
