ffmpeg | branch: master | Carl Eugen Hoyos <cehoyos at ag.or.at> | Thu Jul 11 23:05:53 2013 +0200| [0fff7f039c148a91dde41772d2dc26dd0efb5f89] | committer: Carl Eugen Hoyos

Supply a User-Agent header when opening rtsp streams.

Some rtsp servers like the IP Cam IcyBox IB-CAM2002 need it.
Fixes ticket #2761.
Reported, analyzed and tested by trac user imavra.
