Do I really have to create smil file for every mp4 added to my content catalogue to get adaptive streaming going for on-demand ?

I have adaptive groups for live being generated automatically (e.g \_360p, \_240p, \_all, \_mobile), is there no way to get this automatically for on-demand?

Do I need to write a system script to generate smil-file ? If so I have to restart wowza every time to import the changes right ?

Hi,

A better way would be to have a module where you decide what happens in code when a smil request is made, similar to ngrp for live transcoded streams.

This is possible using AMLST (API for Media Lists) and [is described here.](https://www.wowza.com/forums/showthread.php?14664-New-API-for-resolving-MediaList-%28SMIL-file-requests%29-through-Java-API)
