[vlc-devel] Re: bug - vlc 0.8.2 stream and WMP8

Tue Nov 23 13:15:27 CET 2004

hi,
i've hacked vlc source to return 'HTTP/1.0 404 Not found' on any POST 
request(VLC_ENOOBJ), now i am getting WMP8 error C00D0FCB which should 
mean that file is corrupted

i tried to encode --sout-ffmpeg-keyint 1 which i believe means 'encode 
key frames only' but WMP8 still cannot play stream ...
i'm running out of ideas what could be wrong

good thing is that ffmpeg/ffserver 0.4.8 can stream correct .asf stream 
to any WMP version but ffserver crashes too much to be used for anything 
but testing

i also noticed that ffserver checks for 'NSPlayer' string in User-Agent 
and if it's not there, returns this:
------------------------------
HTTP/1.0 200 ASF Redirect follows
Content-type: video/x-ms-asf

[Reference]
Ref1=http://stream/live.asf
------------------------------
and if it is there:
------------------------------
HTTP/1.0 200 OK
Pragma: no-cache
Server: Cougar 4.1.0.3923
Cache-Control: no-cache
Pragma: client-id=1459286601
Pragma: features="broadcast"
Content-Type: video/x-ms-asf
-------------------------------
and stream starts....
