Description of the issue, suggested solution and other information

Hello.
Some (not all) videos from ustream as the one present in the output above are not supported by youtube-dl.
Here is the callstack of the execution interrupted right at the point where the problem appear:

InfoExtractor._download_json in common line 665	Python
UstreamIE._get_stream_info in ustream line 106	Python
UstreamIE._get_streams in ustream line 113	Python
UstreamIE._real_extract in ustream line 204	Python
InfoExtractor.extract in common line 429	Python
YoutubeDL.extract_info in YoutubeDL line 761	Python
YoutubeDL.download in YoutubeDL line 1890	Python

Inside "InfoExtractor._download_json" the function "_download_webpage" is called to download a JSON-formatted file containing some infos about the video.

Here is the last few lines of a JSON file describing an ustream video that youtube-dl can download:

   "stream":[
               {
                  "name":"uhls",
                  "url":"http://c742eece-lp-live.ums.ustream.tv/playlist/auditorium/recorded/100652907/playlist.m3u8?token=17518093_1491439035019&appType=11&appVersion=2&ts=1491439035&chunkingType=improved&geo=US&sgn=887863d4a1b5549864f56e941dadae2a5f874363&cdnHost=uhs-akamai.ustream.tv/"
               }
            ]
         }
      ],
      "cmd":"moduleInfo"
   }

And the next snippet is from the JSON file of the video I'm trying to download:

"args":[
         {
            "stream":[

            ]
         }
      ],
      "cmd":"moduleInfo"
   }

It seems that the stream link (m3u8 file) is missing in the above JSON file.

Unfortunatly, I have no idea how to solve the issue. And my zero knowledge about python isn't helping me either.

It seems that the video was deleted because it reached 30 day.
Here is annother one with the same problem

http://www.ustream.tv/recorded/101156587 is also gone. Any new example?

Closing as no response for a long time. Feel free to open a new issue if another Ustream video breaks youtube-dl.
