libavformat can't handle mms streaming from http URLs

[gjdfgh]

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.

This is bad, because you can't just tell users they should try "mmsh" instead of "http" if "http" happens not to work.

PS: the fact that links are often playlists containing http URLs makes it even worse. Then users have to download the playlist and change the protocol prefix manually to mmsh.
