Packager settings fields

For Packaging type, choose DASH-ISO.

(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.

(Optional) For Manifest window duration, enter the total duration (in seconds) of the manifest.

(Optional) For Profile, choose a DASH profile that determines the segment and manifest formats of the output.

(Optional) For Manifest layout, choose if you want MediaPackage to serve a full or compact manifest in response to playback requests.

For more information about the manifest layout options, see Compacted DASH manifests.

(Optional) For Min update period, enter the minimum amount of time (in seconds) that the player should wait before requesting manifest updates. A lower value means that manifests are updated more frequently, but a lower value also contributes to request and response network traffic.

(Optional) For Min buffer time, enter the minimum amount of time (in seconds) that a player must keep in the buffer. If network conditions interrupt playback, the player will have additional buffered content before playback fails, allowing for recovery time before the viewer's experience is affected.

(Optional) For Suggested presentation delay, enter the amount of time (in seconds) that the player should be from the end of the manifest. This sets the content start point back x seconds from the end of the manifest (the point where content is live). For example, with a 35-second presentation delay, requests at 5:30 receive content from 5:29:25. When used with time delay, MediaPackage adds the suggested presentation delay to the time delay duration.

(Optional) For Segment template format, choose how MediaPackage and playback requests refer to each segment.

For more information about the formatting options of the SegmentTemplate tag, see DASH manifest segment template format.

(Optional) For UTC timing, select the method that the player uses to synchronize to coordinated universal time (UTC) wall clock time. This enables the player and MediaPackage to run on the same UTC wall clock time. This is a requirement, otherwise playback timing or synchronization issues can occur.

The options are HTTP-HEAD, HTTP-ISO, HTTP-XSDATE, and NONE. This value will be set as the @schemeIdURI attribute for the UTCTiming element in the outbound Media Presentation Description. For information about UTCTiming, see DASH, UTC Timing Descriptor, 5.8.4.11.

(Optional) For UTC timing URI, specify a URI to use for UTC synchronization. This is the URI used to fetch the timing data according to the scheme defined by UTC timing. This value is only valid if UTC timing is not NONE. This value will be set as the @value attribute for the UTCTiming element. For information about @value, see DASH, DASH UTC Timing Schemes, 5.8.5.7.

(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 an <EssentialProperty schemeIdUri="http://dashif.org/guidelines/trickmode" value="X"/> descriptor, where X is the ID of the original Adaptation set, and then generates and includes an I-frame only rendition in the stream. If you use encryption, MediaPackage encrypts the I-frame only rendition with the same content key as the original video rendition. This rendition enables player functionality like fast forward and rewind.

For Period triggers, choose how MediaPackage creates media presentation description (MPD) periods in the DASH output manifest. Choose from the following:

(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:

(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.

If you choose not to insert ad markers, MediaPackage also won't create periods. The output manifest is contained in a single period.
