NGINX pseudo streaming with byte range cache on cdn node

need someone expert on getting one of my cdn node setup so it will support nginx byte range requests with cache with mp4 module, the flash player doesn't skip if the support isn't available. HTML5 works fine. currently the nginx node pseudo streaming only works if the mp4 file is local however when requesting via proxy_pass pseudo streaming doesn't work. you need to be skilled with nginx know how to make it work via lua script. your task is to compile nginx from source with required modules on centos 7, document each steps in detail on the way for future deployment by me.
