I tried to add the remoting-plugin, but it didn't work when Weston started.
Here is the configuration in weston.ini file:

[remote-output]
name=remote-output
mode=1280x800
host=192.168.1.103
port=5000

To figure out why it wasn't working,I added logging to the relevant processes in the remoting-plugin.
In the end, I traced the issue to an exception occurring in the third call to the gl_renderer_repaint_output() function, after two repaint processes. This exception occurs on the here

if (gr->swap_buffers_with_damage && !gr->fan_debug) {
...
	ret = gr->swap_buffers_with_damage(gr->egl_display,
					   go->egl_surface,
					   egl_rects, n_egl_rects);
	free(egl_rects);
...

Here is the code statement for the logging I added.

if (gr->swap_buffers_with_damage && !gr->fan_debug) {
	...
	pixman_region_to_egl_y_invert(output, output_damage,
				      &egl_rects, &n_egl_rects);
	weston_log("Debug Info: [%s] %s.\n", __func__, output->name);
	weston_log("Debug Info: [%s] start swap buffer.\n", __func__);
	ret = gr->swap_buffers_with_damage(gr->egl_display,
					   go->egl_surface,
					   egl_rects, n_egl_rects);
	weston_log("Debug Info: [%s] end swap buffer.\n", __func__);
	free(egl_rects);
...

Then, when I run Weston, the weston.log file will have the following content:
