# VOD supported codecs and input types The following sections describe supported input types, input codecs, and output codecs for file-based video on demand (VOD) content. ## Supported input types These are the input types that MediaPackage supports for VOD content. | MediaPackage input type | Use case | | --- | --- | | HLS | Pull an HLS stream set from an Amazon S3 bucket, with or without a secure connection.Additional requirements:[\[See the AWS documentation website for more details\]](http://docs.aws.amazon.com/mediapackage/latest/ug/supported-inputs-vod.html) | | SMIL | Pull an MP4 stream set referenced by a .smil manifest from an Amazon S3 bucket, with or without a secure connection.

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. ``` ```
