Features of AWS Elemental MediaPackage

AWS Elemental MediaPackage supports the following features:

Audio

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.

Important

MediaPackage does not support audio-only inputs. The stream configuration from the encoder must include at least one video track.

Captions

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

DRM

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

HLS Rendition Groups

MediaPackage supports rendition groups for incoming and outgoing HLS content. For information about output redundancy groups, see Rendition Groups Reference in AWS Elemental MediaPackage.

Input Redundancy

Input redundancy is available with only live workflows in AWS Elemental MediaPackage.

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 Live Input Redundancy AWS Elemental MediaPackage Processing Flow.

Subtitles

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

Time-shift viewing is available with only live workflows in AWS Elemental MediaPackage.

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.

Video

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 specification to applicable playback devices.

Important

MediaPackage requires at least one video track to be present in the stream configuration from the encoder. The service does not support audio-only ingest.

Whitelisting

Whitelisting is available with only live workflows in AWS Elemental MediaPackage.

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.
