Nginx + secure pseudo-streaming
View 0. nginx_setup.sh
# Nginx can serve FLV/MP4 files by pseudo-streaming way without any specific media-server software.
# To do the custom build we use 2 modules: --with-http_secure_link_module --with-http_flv_module
# This module "secure-link" helps you to protect links from stealing away.
#
# NOTE: see more details at coderwall: http://coderwall.com/p/3hksyg
