I never really looked at HTTP writing. So, since we're doing streaming
here, the very first thing that should be done is to not send out
Content-Range and set is_stream=1 for write-HTTP streams. But I'm not
sure if that's the issue here.
The whole of ffserver currently sends out HTTP/1.0 headers. At least the
OK reply should become HTTP/1.1 (line 1527 in ffserver.c), but we don't
really check that in http.c, so I still don't think that's the problem.
Besides, line 1196 already appears to have basic awareness of the fact
that a client may, in fact, ask for HTTP/1.1.
Somehow, I get the feeling that other parts inside ffserver will still
reject it (although a quick read doesn't really make it obvious to me
where those checks are done yet). I would need to test that to make
sure.
So, I've tried setting up a ffserver locally for testing (i.e. I
transcoded a mp3 to /tmp/gl.ffm using "./ffmpeg
-i /tmp/gl.mp3 /tmp/gl.ffm" and then use the resulting .ffm file for
recorded streaming), but I can't really get it to stream (it segfaulted
when I did a wget http://localhost:8090/gl.mp3 :-), see attached
ffserver.conf), does anyone know how to make this work?

Also, "P." (sorry, I can't find your name), things like
commandline-output of ffserver would be useful. With a bit of luck, it
spits out errors so we can find where the problem really is.
