RPi OS (Bullseye) has abandoned the omx (OpenMAX) driver used till now for this by [RPiPlay](http://github.com/FD-/RPiPlay), in
favor of v4l2 (Video4Linux2). The GStreamer Video4Linux2 plugin only works with UxPlay since GStreamer-1.21.0.0 on the development branch,

On "Desktop" operating systems, use the options `uxplay -rpigl`

systems with the 5.10.x Linux kernel,
but the recent upgrade of RPi OS to 5.15.x kernels seems to have a regression that causes unacceptable latency.
On "Desktop" operating systems with X11, use `uxplay -v4l2` (or use ``-rpi `` as a synonym),

1.51 2022-04-24 Reworked options forVideo4Linux2 support (new option -v4l2) and short options -rpi, -rpifb, -rpiwl as
synonyms for -v4l2, -v4l2 -vs kmssink, and -v4l2 -vs waylandsink. Reverted a change from 1.48 that broke

1.50 2022-04-22 Added -fs fullscreen option (for Wayland or VAAPI plugins only), Changed -rpi to be for framebuffer ("lite") RPi
systems and added -rpigl (OpenGL) and -rpiwl (Wayland) options for RPi Desktop systems.
Also modified timestamps from "DTS" to "PTS" for latency improvement, plus internal cleanups.
