value
Use an ISO 8601 time value between 0.5 to 20 seconds to specify the output fragment length for the video and audio tracks of an encoding live event. For example, use PT2S to indicate 2 seconds. For the video track it also defines the key frame interval, or the length of a GoP (group of pictures). The value cannot be set for pass-through live events. Defaults to PT2S.
