keepSegments property
Applies only if Mode field is LIVE.
Specifies the number of media segments to retain in the destination directory. This number should be bigger than indexNSegments (Num segments). We recommend (value = (2 x indexNsegments) + 1).
If this "keep segments" number is too low, the following might happen: the player is still reading a media manifest file that lists this segment, but that segment has been removed from the destination directory (as directed by indexNSegments). This situation would result in a 404 HTTP error on the player.
Implementation
final int? keepSegments;
