Overview
When passing DASHFragmentSelector as input to an Aws::Client method, you can use a vanilla Hash:
{
fragment_selector_type: "PRODUCER_TIMESTAMP", # accepts PRODUCER_TIMESTAMP, SERVER_TIMESTAMP
timestamp_range: {
start_timestamp: Time.now,
end_timestamp: Time.now,
},
}
Contains the range of timestamps for the requested media, and the source of the timestamps.
Returned by:
Instance Attribute Summary collapse
-
#fragment_selector_type ⇒ String
The source of the timestamps for the requested media.
-
#timestamp_range ⇒ Types::DASHTimestampRange
The start and end of the timestamp range for the requested media.
Instance Attribute Details
#fragment_selector_type ⇒ String
The source of the timestamps for the requested media.
When FragmentSelectorType
is set to PRODUCER_TIMESTAMP
and
GetDASHStreamingSessionURLInput$PlaybackMode is ON_DEMAND
or
LIVE_REPLAY
, the first fragment ingested with a producer timestamp
within the specified FragmentSelector$TimestampRange is included
in the media playlist. In addition, the fragments with producer
timestamps within the TimestampRange
ingested immediately following
the first fragment (up to the
GetDASHStreamingSessionURLInput$MaxManifestFragmentResults value)
are included.
Fragments that have duplicate producer timestamps are deduplicated. This means that if producers are producing a stream of fragments with producer timestamps that are approximately equal to the true clock time, the MPEG-DASH manifest will contain all of the fragments within the requested timestamp range. If some fragments are ingested within the same time range and very different points in time, only the oldest ingested collection of fragments are returned.
When FragmentSelectorType
is set to PRODUCER_TIMESTAMP
and
GetDASHStreamingSessionURLInput$PlaybackMode is LIVE
, the
producer timestamps are used in the MP4 fragments and for deduplication.
But the most recently ingested fragments based on server timestamps are
included in the MPEG-DASH manifest. This means that even if fragments
ingested in the past have producer timestamps with values now, they are
not included in the HLS media playlist.
The default is SERVER_TIMESTAMP
.
Possible values:
- PRODUCER_TIMESTAMP
- SERVER_TIMESTAMP
#timestamp_range ⇒ Types::DASHTimestampRange
The start and end of the timestamp range for the requested media.
This value should not be present if PlaybackType
is LIVE
.
