Systems and methods for dynamically syncing from time-shifted frame to live stream of content
Systems and methods for skipping a presentation of a portion of segments to catch up to live based on a priority level value is disclosed. For example, a streaming application generates a content item for live streaming where the content item comprises a plurality of segments. In response to determining that playing of the content item lags behind the live streaming of the content item, the streaming application identifies a duration of lag and determines a priority threshold based on the lag. Based on a manifest which includes priority level information, the streaming application determines whether a respective segment needs to be cached. For example, if a priority level for a segment that is within the duration of the lag has a priority level that is higher the priority threshold, then the segment is stored in a cache from a respective network address and is played from the cache.
