I have develop gstreamer application for about half year, I now try to write
custom element because application code couldn't do my task, to separate
side-by-side video, eg: a combined 2 sensor video data from MIPI CSI2, both
have the same resolution/fps.

According to plugin writer's guide,
My command is:

git clone
cd gst-template
meson builddir
ninja -C builddir

On ubuntu 18.04, its built-in gsteramer version is 1.14.5, but the request 1.19.
I tried to modify version check, and then ninja is failed.

I further check the gstreamer version of Ubuntu 20.04, is 1.16.x.

So if I want to process the guide, do I need to build the latest gstreamer
Thanks a lot.
