The same way MPlayer would... And it has the advantage that it can
assume that all filenames start with a protocol specifier like http://
rtsp:// etc.
And no, MIME type won't work. It doesn't even work with "normal" files,
there are just to many plain stupid people creating websites.
Just as an example: that rtsp URL that didn't work with MPlayer but with
RealPlayer, do you know why? The streaming server they used (Darwin
Streaming Server) doesn't support .rm file (only mov). RealPlayer just
does a fallback to "wgetting" the file via a normal webserver on port
80...
