2022-08-09cam: sdl_texture: Rename 'pitch' to 'stride'Laurent Pinchart
The libcamera public API uses 'stride' to refer to the line stride. Rename the SDLTexture::pitch_ member variable for consistency. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Reviewed-by: Eric Curtin <ecurtin@redhat.com> Reviewed-by: Jacopo Mondi <jacopo@jmondi.org>
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.

2022-07-28cam: 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.

2022-07-28cam: 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.
