Hello everyone,

I am trying to do something very specific with vlc/vls, and am unable to
find example to help me.

1) multicast a mp4 stream with an provide an sdp description file 
(basically like mp4live from mpeg4ip)

I figured this line out from the docs:
vlc -vvv
v4l:/dev/video0:channel=0:adev=/dev/dsp:audio=1:size=vga:norm=ntsc:frequency
=433250
--sout
'#transcode{vcodec=mp4v,vb=2048,scale=1,acodec=mpga,ab=192,channels=2}:#rtp{
dst=224.1.2.3:port=1234:sdp=rstp://1.1.1.1:9090/test.sdp }'

When I run this line... I get all sorts of errors... 
In particular sout modules transcode,none not found, rtp,none not found,...

Vlc keeps running, but my cpu load is all idle.

Is the command line ok?
Can somebody help me?

2) also, I saw on the cvs's changelog and files  that a lot of info about
h264 is present... (cd /somewhere/vlc_cvs; grep -R h264 *)

Does that mean that I can set vcodec=h264 in the transcode section?

Thank you very much all for your help
