#2480: libavformat can't handle mms streaming from http URLs

The following URL works fine with mplayer and VLC, but not ffplay:
{{{
http://direct.francetv.fr/regions/evt/medit-nice-direct.wsx?MSWMExt=.asf
}}}
However, using mmsh as protocol instead make it work:
{{{
mmsh://direct.francetv.fr/regions/evt/medit-nice-direct.wsx?MSWMExt=.asf
}}}
It looks like libavformat is missing some logic to recognize that a http
URL is actually mms.
The following is even "harder", as in that it doesn't work with mplayer or
ffplay, and only VLC:
{{{
http://wm.microsoft.com/ms/evnet/Vista_Diagnostics_s_ch9.wmv
}}}
This is bad, because you can't just tell users they should try "mmsh"
instead of "http" if "http" happens not to work.
