GetDashStreamingSessionUrlRequest

The time range of the requested fragment and the source of the timestamps.

Fragments are identified in the manifest file based on their sequence number in the session. If DisplayFragmentNumber is set to ALWAYS, the Kinesis Video Streams fragment number is added to each S element in the manifest file with the attribute name “kvs:fn”. These fragment numbers can be used for logging or for use with other APIs (e.g. GetMedia and GetMediaForFragmentList). A custom MPEG-DASH media player is necessary to leverage these this custom attribute.

Per the MPEG-DASH specification, the wall-clock time of fragments in the manifest file can be derived using attributes in the manifest itself. However, typically, MPEG-DASH compatible media players do not properly handle gaps in the media timeline. Kinesis Video Streams adjusts the media timeline in the manifest file to enable playback of media with discontinuities. Therefore, the wall-clock time derived from the manifest file may be inaccurate. If DisplayFragmentTimestamp is set to ALWAYS, the accurate fragment timestamp is added to each S element in the manifest file with the attribute name “kvs:ts”. A custom MPEG-DASH media player is necessary to leverage this custom attribute.

The time in seconds until the requested session expires. This value can be between 300 (5 minutes) and 43200 (12 hours).

The maximum number of fragments that are returned in the MPEG-DASH manifest.
