Features of AWS Elemental MediaPackage

AWS Elemental MediaPackage supports the following features:


AWS Elemental MediaPackage supports multi-language audio inputs, as well as the following audio codecs:

  • AAC stereo

  • Dolby AC3 and E-AC3 (Dolby Digital and Dolby Digital+)

AWS Elemental MediaPackage accepts these codecs from the input source and passes them through to the output stream.


AWS Elemental MediaPackage supports input 608/708 captions and passes them through to the output stream.


AWS Elemental MediaPackage supports content protection through digital rights management (DRM).

Input Redundancy

AWS Elemental MediaPackage creates two input URLs on every channel so that you can create input redundancy by sending two identical streams to the same channel. For information about how input redundancy works, see How Input Redundancy Works.


AWS Elemental MediaPackage supports input WebVTT text-based subtitles. MediaPackage translates the subtitles to the appropriate format based on the packager that is used on the endpoint:

  • For HLS and CMAF: WebVTT is passed through

  • For DASH: subtitles are translated to EBU-TT

  • For Microsoft Smooth Streaming: subtitles are translated to DFXP

Time-shift Viewing

AWS Elemental MediaPackage allows playback of a stream at a time earlier than the current time. Start-over, catch-up TV, and time delay are all supported. For more information about setting up time-shift capabilities, see Time-shifted Viewing Reference in AWS Elemental MediaPackage.


AWS Elemental MediaPackage supports the input H.264 video codec and passes it through to the output stream. Common Media Application Format (CMAF) endpoints in MediaPackage also support H.265/HEVC and HDR-10 following the Apple spec to applicable playback devices.


AWS Elemental MediaPackage supports restricting network access to the endpoint. To take advantage of this feature, you must enter the allowed IP addresses on the endpoint. For more information about adding whitelisting information, see Access Control Fields.
