Requirements for .smil manifests

When sending a VOD MP4 asset to AWS Elemental MediaPackage, a .smil manifest must be included. The .smil manifest is an XML file that acts as a wrapper for all the files in the asset, letting MediaPackage know which MP4s are part of a single asset.

Resources

MediaPackage supports the following attributes in a .smil manifest.

Attributes

  • audioName - The name of the audio track, such as English 2.

  • includeAudio -A Boolean value indicating if the audio tracks should be included. If not specified, all tracks default to true.

  • src or name - Either the name or the source of the text stream or video file relative to the manifest location.

  • subtitleName - The subtitle name, such as English.

  • systemLanguage or language - The system language, such as eng.
