Setting Up Dynamic Multiview Outputs (Console) - MediaLive

Setting Up Dynamic Multiview Outputs (Console)

This section walks through creating a multiview output group in the AWS Elemental MediaLive console. Repeat it for each source feed — one MediaLive channel per feed.

Before you start

  • A MediaPackage V2 channel group containing one channel per source feed.

  • A decision about which layouts you want to support, which determines the renditions you need. See How Dynamic Multiview works.

To create a multiview output group

  1. Create or edit the channel. Create the channel as you normally would, or open an existing channel for editing. Configure the input and input attachment first; nothing about the input is multiview-specific.

  2. Add a multiview output group. Add an output group and choose the MediaPackage Multiview output group. This will create a MediaPackage output group. There isn't a new "multiview" output group variant in the API or SDK, but the MediaPackage Multiview option in the console is a shortcut to help expedite and simplify encode setup for multiview.

  3. Answer the wizard prompts. The console asks for the properties it needs to generate a valid set of outputs:

    • Codec – H.264, H.265, or both.

    • Frame rate – Choose the default frame rate to configure. All properties are editable afterwards.

    • Layout support – Whether you want MediaLive to generate encodes that are suited for equal-size layouts, primary/secondary layouts, or both.

    The wizard uses these answers to generate a set of outputs with dimensions, encoder settings, and multiview usage roles already filled in so the channel has a tuned ABR stack and passes validation. All properties can be edited afterwards if changes are desired.

  4. Review the generated outputs. The wizard creates an output group backed by a MediaPackage V2 destination with CMAF Ingest outputs. Enter the MediaPackage channel group name and the endpoint ID.

    Also, check the generated outputs before saving. For each one, confirm:

    • Resolution – that the ladder covers the range you want, and that primary/secondary pairs are in an exact 2:1 relationship.

    • Bitrate – the wizard's defaults are a starting point; tune them for your content.
