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="ExampleCC.srt" systemLanguage="eng"/>
    </switch>
  </body>
</smil>
