	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.
