Using external assets on Phoenix

Hello guys, I’m currently trying to use some static assets (images and videos) which are not stored under the priv folder of Phoenix app. Normally I would simply use the helpers and provide a relative path to the static_path/2 function. However, it’s the first time using files that are outside of the usual assets folder. How should I correctly use the path for these files? If I use the absolute path, a localhost:4000 is always prepend to the src attribute.
