Rewind MediaPackage generated live stream to beginning

Hello,

You'll want to use the Startover window along with time-shifted viewing in order to accomplish this. You can set the Startover window to up to 14 days from when the content was streaming live. You can then use query parameters to send the player to the start time of the event, or times in between by passing different query paramenters to the same endpoint. You can do this while the live event is still running. If the player requests the manifest without any query parameters it will send it to the live window, but with start and/or end parameters you can send the player to a specific time in the past as long as the time in the past is within the startover window. Here's a bit more documentation around how to accomplish that: https://docs.aws.amazon.com/mediapackage/latest/ug/time-shifted.html?icmpid=docs_elemental_mediapackage_helppanel
