Icecast - Aug 2004 - how to start liveice with screen?

Moin,
I installed liveice as well as 'screen' at a debian maschine, both 
applications are running fine. But when I try to start liveice in a
'screen'
environment then the liveice process ends without an error message:

$ /usr/bin/screen -dmS liveice  /usr/bin/liveice

A prefixed 'strace -f' shows me:
[pid  5614] old_mmap(NULL, 167936, PROT_READ|PROT_WRITE, 
MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x40187000
[pid  5614] write(2, "LAME version 3.92  (http://www.m"..., 45) = 45
[pid  5614] write(2, "usage: /usr/bin/lame [options] <"..., 542) =
542
[pid  5614] _exit(1)

Why is 'lame' started with wrong (in fact: with no) parameters? When
liveice
is startet direct it runs and feeds my icecast server.
Does anybody start liveiceusing screen and can give me the command line?
Thanks

We did the same and it's working OK here :-)

It's just a test if lame is executable at all. In fact lame is executed
twice by liveice.

If you look carefully at your strace output, you will notice a failing
setpgid() call. This patch worked for me:

<p>This is my command line:

USER=`whoami`
CONFIG="/etc/liveice/$USER.cfg"
R="/home/www.scram.fm/mitschnitte/`date +%Y%m%d_%H%M%S`.mp3"

udo /usr/bin/screen /opt/liveice/liveice -F $CONFIG -R $R -V

"-R" is yet another parameter added by me to control the remote dump
file.
