Ustream - die faster when a segment ends

[personalt]

I am recording something on Ustream where there are 10 minute video segments. I have a separate batch file looping the following command. It works great except when the stream ends it take a good 10 seconds for livestreamer to 'fail' and exit (in order to restart)

If there any modifications I can make to get it to fail quicker? At the end I think it echos an error about failure to retrieve the header. I will post the exact message in a bit.

livestreamer --retry-streams 1 --retry-open 200000 --stream-segment-threads 3 --stream-segment-attempts 4 -o "watch1 01.flv" "https://www.ustream.tv/embed/XXXX" 720p+
