digitalFAQ.com Forums [Archives] - FFMPEG: Need a good script for mencoder

Hello

I'm a newbabe in linux and I don't understand the english forum full.

I have opened a post in spanish forum about mencoder.
http://www.kvcd.net/forum/viewtopic.php?p=72937

I'm trying this script

Code:

#!/bin/bash

#

# Copyright (C) 2003-2038 russiansexpat

#

# script:       mpeg(1,2,3,4) conversion to (S,X)VCD with quantisation matrix

#               and auto-splitting into multiple CDs and writing them.

#

# requires:     mencoder(1.0pre3) mplayer mplex vcdimager cdrdao

# optional:     normalize toolame(0.2k)

#

# does not require: microsoft. This script has not been tested on animals.

#

# version 0.3

#

# Changeslog

#

# - Added subtitle suport (Alexandre Possebom(otzi))

#



for exe in mencoder mplayer mplex vcdim

ager cdrdao; do

   if [ -z "`which $exe`" ]; then

      echo "ERROR: $exe must be in your path $PATH"

      exit 1

   fi

done

And I have this error:

Code:

$ ./ofkvcd.sh corte.avi

./ofkvcd.sh: line 21: syntax error near unexpected token `ager'

./ofkvcd.sh: line 21: `ager cdrdao; do'

Wath is the problem? Sorry I am rokkie in linux

If you are trying other script, give me it !!

Thanks from spain!!

P.S. excuse me for my bad english
