[MPlayer-dev-eng] [PATCH] Following ASF redirections and detecting ASX playlist

[bl4]

Hi,

I've made a patch that fixes problems with ASF streaming I came across 
when streaming Yahoo Launchcast. In response to an HTTP request, server 
replies with an ASF content-type and a single URL in the content. 
Instead of following this URL and making another request, mplayer wants 
to stream the original URL and fails. Before I made this patch, I had to 
write a Perl script that followed these redirections until it received 
an MMS URL. Then the script passed the URL to mplayer.

With this patch, when an HTTP response is received with an ASF 
content-type, mplayer checks if the content starts with `http://` or 
`mms://`. If it does, it makes another HTTP request (if http) or changes 
the current URL to the new one (if mms).

The second problem is ASX playlist detection. If mplayer is started with 
-playlist option, everything is fine, but I think it should be the 
player, not the user, that checks if the URL is a playlist. Especially 
if one uses mplayer plugin in a web browser and doesn't have chance to 
modify mplayer command line.

mplayer only checks the content-type. If it's an ASX content-type, the 
URL is treated as playlist. But if it's an ASF content-type, the URL is 
always treated as stream. mplayer doesn't check the content, even if it 
contains a playlist. With this patch, when the content-type of an HTTP 
response indicates ASF, mplayer checks if the content starts with `<asx`.
