[MPlayer-users] Playing WMV over HTTP fails when Proxy is used

[Robert Huitl]

Hello,

I use MPlayer through KMPlayer, which sets the http_proxy environment variable 
depending on my Desktop's proxy settings. These are set to a host running 
Privoxy.

When the proxy is used, MPlayer fails to play the movie, because the proxy 
server answers something like "400 - Bad Request". This is caused by the 
"Host: server:0" line (see below), where the port number is set to 0.

I tried to fix that with the attached patch, and the bad-request-error is 
gone. But still the video is not played, MPlayer does nothing and finally 
quits with "end of file" after some seconds:

$ http_proxy="http://homebase:8118" mplayer

Also, I'm wondering why the User-Agent reported by MPlayer is different 
depending on whether a proxy is used. That line "ASF Redirector" is not 
printed when no proxy is used. There seems to be some special handling for 
ASF in MPlayer, which is triggered by setting a proxy server.

These are the HTTP requests that MPlayer sends out:

MPlayer, without Proxy:
=======================
GET /vids/vid_00965.wmv HTTP/1.0
Host: media.skoopy.com
User-Agent: MPlayer/1.0pre7try2-3.3.6
Connection: close
 
 
MPlayer, with Proxy (http_proxy="http://proxy:8118" mplayer url):
=================================================================
GET http://media.skoopy.com/vids/vid_00965.wmv HTTP/1.0
Accept: */*
User-Agent: NSPlayer/4.1.0.3856
Host: media.skoopy.com:0
