Rules for Rendition Groups - AWS Elemental Server

Rules for Rendition Groups

Rules exist for associating both audio and video streams in their respective rendition groups. These are described following.

  • A given audio stream can belong to only one audio rendition group.

  • Any given video stream can be associated with more than one rendition group. (For example, “video high” can be associated with both “Dolby audio streams” and “AAC audio streams.” You do not need to create two video streams.)

    With this setup, all the rendition groups associated with the same video stream must contain the same audio streams.( For example, “Dolby audio streams” and “AAC audio streams” must contain the same audio streams (perhaps English, French and Spanish)).

  • Any given audio rendition group can be associated with more than one video stream.( For example, “Dolby audio streams” rendition group can be associated with “video high” and “video low.” You do not need to create two rendition groups, one for each video.)

  • Any video stream can be associated with more than one output group. (For example, “video high” can appear in two different HLS output groups).

You can use a combination of these rules. For more information, see Examples of HLS Rendition Groups.
