livestreamer and ustream.tv - no longer one file, advice?

[FredThompson]

I've been using livestreamer to access creativelive.com feeds.

Windows OS and calls are similar to this:

livestreamer --retry-streams 1 --retry-open 200000 --stream-segment-threads 3 --stream-segment-attempts 4 -o "watch3 46.flv" "https://www.ustream.tv/embed/12858204" 720p+

This worked until a few weeks ago and now there are only short segments being captured. My guess is the streams are now Adobe HDS segments but I don't know how to confirm.

Would someone please tell me if they have the same results and, if so, how to grab such streams now?
