Lowering this value will lower latency but may decrease the player's ability to build a stable buffer.
Minimum latency deviation allowed before activating catch-up mechanism.
Maximum catch-up rate, as a percentage, for low latency live streams.
Use this parameter to set the maximum threshold for which live catch up is applied. For instance, if this value is set to 8 seconds, then live catchup is only applied if the current live latency is equal or below 8 seconds. The reason behind this parameter is to avoid an increase of the playback rate if the user seeks within the DVR window.
