Packager settings fields - AWS Elemental MediaPackage

Packager settings fields

The Packager settings fields hold general information about the endpoint.

  1. For Packaging type, choose Apple HLS.

  2. (Optional) For Segment duration, enter the duration (in seconds) of each segment. Enter a value equal to, or a multiple of, the input segment duration. If the value that you enter is different from the input segment duration, AWS Elemental MediaPackage rounds segments to the nearest multiple of the input segment duration.

  3. (Optional) For Live playlist window duration, enter the total duration (in seconds) of the parent manifest.

  4. (Optional) Select Use audio rendition group to group all audio tracks into a single HLS rendition group. For more information about rendition groups, see Rendition groups reference in AWS Elemental MediaPackage.

  5. (Optional) Select Include DVB subtitles to passthrough DVB subtitles into the output.

  6. (Optional) Select Include IFrame only stream to include an additional I-frame only stream along with the other tracks in the manifest. MediaPackage generates an I-frame only stream from the first rendition in the manifest. The service inserts EXT-I-FRAMES-ONLY tags in the output manifest, and then generates and includes an I-frames only playlist in the stream. This playlist enables player functionality like fast forward and rewind.

  7. (Optional) For Program date/time interval, enter the interval (in seconds) for MediaPackage to insert the EXT-X-PROGRAM-DATE-TIME tags in the manifest.

    The EXT-X-PROGRAM-DATE-TIME tag holds the time of the segment. When program date time (PDT) information is available in the source content, MediaPackage uses this same information on the output content. Otherwise, MediaPackage uses Coordinated Universal Time (UTC) for the PDT.

    The PDT information helps downstream players to synchronize the stream to the wall clock, enabling functionality like viewer seek in the playback timeline and time display on the player.

  8. (Optional) For Playlist type, choose Event or VOD. When specified as either event or VOD, a corresponding EXT-X-PLAYLIST-TYPE entry is included in the media playlist. Indicates if the playlist is live to VOD content.

SCTE-35 Options

The following fields dictate how MediaPackage processes SCTE-35 messages from the input stream. For more information, see SCTE-35 message options in AWS Elemental MediaPackage.

  1. (Optional) For 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.

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

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

    • Daterange – Emit EXT-X-DATERANGE tags in HLS and CMAF manifests to signal ads and program transitions.

  2. (Optional) For Ad triggers, choose the SCTE-35 message types that you want to be treated as ad markers in the output. If you don't make a selection here, MediaPackage inserts ad markers in the output manifest based on these message types:

    • Splice insert

    • Provider advertisement

    • Distributor advertisement

    • Provider placement opportunity

    • Distributor placement opportunity

  3. (Optional) For Ads on delivery restrictions, choose what ad insertion action MediaPackage takes based on delivery restriction flags in the segmentation descriptors of SCTE-35 messages.

    • None – MediaPackage doesn't insert any ad markers in the output manifest.

    • Restricted – MediaPackage inserts ad markers when there are delivery restrictions in the SCTE-35 message types that you indicated in Customize ad triggers.

    • Unrestricted – MediaPackage inserts ad markers when there aren't delivery restrictions in the SCTE-35 message types that you indicated in Customize ad triggers.

    • Both – MediaPackage inserts ad markers whether or not there are delivery restrictions in the SCTE-35 message types that you indicated in Customize ad triggers.
