[http://ldt.iri.centrepompidou.fr] JW Player with content lead to UnsupportedError(URL) in _real_extract

[cregouby]

Hello,
This mooc content is available through JVPlayer (flash) and should lead to a mp4 video.
Right now it seems that youtube-dl fallbacks to default extractor and is missing the rtmp part extraction of the content
Using chrome browser in conjunction with wireshark provides the following decode in the rtmpt flow : "Real Time Messaging Protocol (AMF0 Command play('mp4:video/ldtplatform/upload/cours_ic01/cours1.mp4'))" - no idea if it helps-
Thanks a lot for your support
Christophe
