ustream via https - no path found - is my call format correct?

Win8.1x64 youtube-dl 2016-08-13
goal is to catch successive streams on an https ustream.tv recorded feed

Sample calls made through batch file:

youtube-dl.exe -o "watch2 01.flv" -v "https://www.ustream.tv/embed/12858195"
youtube-dl.exe -o "watch2 02.flv" -v "https://www.ustream.tv/embed/12858195"
youtube-dl.exe -o "watch2 03.flv" -v "https://www.ustream.tv/embed/12858195"
youtube-dl.exe -o "watch2 04.flv" -v "https://www.ustream.tv/embed/12858195"
...

The -v status includes:

[ustream] 12858195: Downloading webpage
[download] Downloading playlist: 12858195
[ustream] playlist 12858195: Downloading 0 videos
[download] Finished downloading playlist: 12858195

Would someone please tell me how to fix the youtube-dl calls?

Live streams are not supported.

I'm not sure how to respond. I stated these are recorded streams.

livestreamer works but the end of each stream is lost:

livestreamer --retry-streams 1 --retry-open 200000 --stream-segment-threads 3 --stream-segment-attempts 4 -o "watch2 01.flv" "https://www.ustream.tv/embed/12858195" 720p+

https://www.ustream.tv/embed/12858195 is a live stream.

By "live" do you mean it's a data stream as opposed to a static file?
If so, I'm back to chasing the buffering issue in livestreamer.
