[vlc] Re: HELP: vlc multicasting problems...

Hi....

Thanx for the reply.....actually it seems to be only live streams. I just 
tried multicasting a DVD and it worked everytime.

I realise this probably points the finger at vdr+streamdev, but I can do the 
following:

[Server]
vdr+streamdev -> vlc http://localhost:3000/PS/16331 --sout 
'#standard{access=http,mux=ts,url=:1234}'

[Client]
vlc http://[Server]:1234

and this works perfectly, so it seems that the vlc server process is 
receiving the stream from vdr+streamdev.

It only seems to not work when I tell --sout to use multicast.....I have 
listed at the end of this post the debug output from a vlc -vvv attempt at 
multicasting.....perhaps you might see something in the output.

Thanx for your help.

Chris.
