# Requirements for .smil manifests
<a name="supported-inputs-vod-smil"></a>

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**
+ For guidance on creating a .smil manifest, see [.smil using AWS Elemental MediaPackage VOD](https://aws.amazon.com/blogs/media/smil-using-aws-elemental-mediapackage-vod/) (blog).
+ For general information about Synchronized Multimedia Integration Language (SMIL), see the [SMIL 3.0 specification](https://www.w3.org/TR/SMIL/).

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. This attribute should contain as many values as there are languages defined. 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`.

**Example .smil manifest**  
The following is an example of a `.smil` manifest.   

```
<?xml version="1.0" encoding="utf-8"?>
<smil>
    <body>
        <alias value="Example"/>
        <switch>
            <video name="example_360.mp4" systemLanguage="eng,fra,spa" audioName="English,French,Spanish" includeAudio="true,true,true"/>
            <video name="example_480.mp4" systemLanguage="eng" audioName="English 2" includeAudio="false"/>
            <textstream src="example_subs_eng.srt" systemLanguage="eng" subtitleName="English" includeAudio="false"/>
            <textstream src="example_subs_fra.srt" systemLanguage="fra" subtitleName="French" includeAudio="false"/>
            <textstream src="example_subs_spa.srt" systemLanguage="spa" subtitleName="Spanish" includeAudio="false"/>
    </switch>
</body>
</smil>
```
