Creating a SMIL File

When you send an VOD MP4 asset to AWS Elemental MediaPackage, you have to include a Synchronized Multimedia Integration Language (SMIL) file as well. This .smil file acts as a wrapper for all of the files that are part of the asset.

MediaPackage supports the following attributes in a .smil file:

  • name

  • src

  • language

  • systemLanguage

Example Supported SMIL Structure

The following is an example of a .smil manifest that MediaPackage supports. It references video files ExampleHigh, ExampleMid, and ExampleLow and captions file ExampleCC.

<?xml version="1.0" encoding="utf-8"?> <smil> <head></head> <body> <switch> <video name="ExampleHigh.mp4" /> <video name="ExampleLow.mp4" /> <video name="ExampleMid.mp4" /> <textstream src="" systemLanguage="eng"/> </switch> </body> </smil>
