I searched here for ‘NACK’ and didn’t find a good match in the top results.
Note: If you use UDP ICE candidates, enabling NACK messages is recommended to allow for retransmission of lost packets. See the optional RTP properties in Configure a live application for information about how to enable NACK with Wowza Streaming Engine XML.
that page it links to (I can’t relink it here because this forums software thinks I am a new user trying to link more than 2 urls) isn’t showing me information about enabling NACK. When I use the search function I am not currently finding it on wowza.com.
