How to use OpenCV with gstreamer support on X86 platform?

@CoderJustin

But this time I want to run on x86, some say the nv-gst-plugin only work on ARM machine?

DS propvides DS plugins, e.g. nvv4l2decoder, that has the same name, properities on Jetson/ARM and x86.
But some NV plugins, e.g. nvvidconv , is not DS plugin, which can only work on Jetson.

Here is the reference - DeepStream SDK FAQ - #15 by Fiona.Chen about DS plugin and non-DS plugin
