OK, I'm all in old-fashioned mode now, vanilla svn with --disable-ipv6.

I'm using that, ./ffplay test.mpg works.

ffserver.conf:

RTSPPort 8091
RTSPBindAddress 0.0.0.0
MaxClients 1000
MaxBandwidth 1000
CustomLog -
NoDaemon

<Stream test1.mpg>
Format rtp
File "/Users/ronaldbultje/Projects/ffmpeg/test.mpg"
</Stream>

Starting ffserver and connecting a client (ffplay
rtsp://127.0.0.1:8091/test1.mpg):

$ ./ffserver -f ffs.cnf
FFserver version SVN-r10739, Copyright (c) 2000-2007 Fabrice Bellard, et al.
  configuration: --disable-ipv6

ffserver started.
127.0.0.1 - - [Mon Oct 15 08:18:28 2007] "DESCRIBE
rtsp://127.0.0.1:8091/test1.mpg RTSP/1.0" 200 275

In ipv6-mode, I get a log message that says that the client sent a DESCRIBE
command when I connect the client. Here, I get it only when I quit the
client, suggesting a data caching problem (?). Client gives me nothing
otherwise.

What appears in ffserver's log? Can you try using "vlc -vvv <rtsp url>"

I'll need to try this later, I don't have any of that installed yet...

Thanks,
