AWS Elemental MediaPackage
User Guide

Packager Settings Fields

  1. For Type, choose Apple HLS.

  2. (Optional) For Segment duration, type the duration (in seconds) of each segment. If the value that you type here is different from the input segment size, AWS Elemental MediaPackage rounds segments to the nearest multiple of the input segment duration.

  3. (Optional) For Playlist window duration, type the total duration (in seconds) of the manifest.

  4. (Optional) To group all audio tracks into a single HLS rendition group, select Use audio rendition group. For more information about rendition groups, see Rendition Groups Reference in AWS Elemental MediaPackage.

  5. (Optional) To include an I-frame only stream along with the other tracks in the manifest, select Include IFrame only stream. This option is valid in stream sets with a single video track only. AWS Elemental MediaPackage inserts EXT-I-FRAMES-ONLY tags in the manifest, and then compiles and includes an I-frames only playlist in the stream. This playlist enables player functionality like fast forward and rewind.

  6. (Optional) To include EXT-X-PROGRAM-DATE-TIME tags in the output manifest, select Program date/time interval, and then type the interval for AWS Elemental MediaPackage to insert the tags in the manifest.

    The EXT-X-PROGRAM-DATE-TIME tag synchronizes the stream to the wall clock, enabling functionality like viewer seek in the playback timeline and time display on the player.

  7. (Optional) In Ad markers, choose how ad markers are included in the packaged content.

    Choose from the following:

    • None – Omit all SCTE-35 ad markers from the output.

    • SCTE-35 enhanced – Generate ad markers and blackout tags based on the SCTE-35 input messages from the input source.

    • Passthrough – Copy the SCTE-35 ad markers directly from the input HLS input manifest to the output manifest.
