Issue:
[UstreamIE] [generic] Please add support for Ustream embed URLs
Example embed page http://www.american.edu/spa/pti/nsa-privacy-janus-2014.cfm

Example embed URL: http://www.ustream.tv/embed/17357891?wmode=direct

As best as I can tell, the `video_id` differs from the normal video vs an embedded one. 

The correct video ID on a normal video can simply be found on the end of the URL. www.ustream.tv/recorded/videoid  whereas the embed page seems to have a different one. 

The proper video ID can be found in the source of the embed page `ContentVideoIds=["45734260"]` that then needs to be passed to UstreamIE.
