Hello,
With YouTube Live you will be sending RTMP which is usually very low latency.
By default HLS needs 3 ten second chunks before starting a stream. To change this please view this article under Configure Properties for Live Streams.
Configure properties for live streams
Use a text editor to open the Application.xml file for your live application. Then add the properties described in the Cupertino segmenter property reference above to the / container. Be sure to add the properties to the correct container in Application.xml as there are several such containers in the file.
I would try a value like this to have 3 two second chunks. If the quality is effected, or buffering occurs, I would recommend upping the cupertinoChunkDurationTarget value.
cupertinoChunkDurationTarget
2000
Integer
cupertinoMaxChunkCount
10
Integer
cupertinoPlaylistChunkCount

cupertinoRepeaterChunkCount

Please save and restart the Wowza Server when making changes.
