Help need to make a shell script run for ffmpeg vhook watermaking in shell

i have a small problem getting a batxh shell script to run in shell

this is the code

Quote:

#!/bin/bash
echo "flv-watermarker converter"
vhook='/usr/local/cpffmpeg/lib/vhook'
output='/var/www/vhosts/mysite.com/httpdocs/con'
fonts='/usr/share/fonts/TrueType'
text='MYSITE.COM'
echo "$vhook - $output - $fonts - $text"
if (($# ==0))
then
echo "Usage: flvwatermarker [flv files] ..."
exit
fi
while (($# !=0 ))
do
ffmpeg -i $1 -sameq -vhook '$vhook/drawtext.so $fonts/Verdana.TTF -t $text -x 5 -y 5' $output/${1%.*}.flv
shift
done
echo "Finished with flv-watermarker converter"

the problem seems to be centered around the ffmpeg command, something maybe to do with the ' ' wrapping around the vhook part command

this is a strange problem , if i take the ffmpeg command and run it directly from the shell promt it works, but inside this shell script it always seems to stop working around the ffmpeg part

i have other simlier shell scripts without the ' ' wrapping around parts of the ffmpeg command and they work fine, just this one seems to not work at all, i have tried adding " " to wrap the hole ffmpeg command, remove the ' ' from the vhook part, but it does not seem to work for me

i'm new to shell scripting and unix, any help or advise as to way this is not working whould be very usefull, thanks in advance

ps this was the orgianl script before i moved some commands into variables, on the ffmpeg line, to stop that long line always breaking onto two lines in nano

platform::shell

platform::shell(n)					       Tcl Bundled Packages						platform::shell(n)

__________________________________________________________________________________________________________________________________________________

NAME

       platform::shell - System identification support code and utilities

SYNOPSIS

       package require platform::shell ?1.1.4?

       platform::shell::generic shell
       platform::shell::identify shell
       platform::shell::platform shell
_________________________________________________________________

DESCRIPTION

       The platform::shell package provides several utility commands useful for the identification of the architecture of a specific Tcl shell.

       This  package  allows the identification of the architecture of a specific Tcl shell different from the shell running the package. The only
       requirement is that the other shell (identified by its path), is actually executable on the current machine.

       While for most platform this means that the architecture of the interrogated shell is identical to the architecture of  the  running  shell
       this  is  not generally true. A counter example are all platforms which have 32 and 64 bit variants and where a 64bit system is able to run
       32bit code. For these running and interrogated shell may have different 32/64 bit settings and thus different identifiers.

       For applications like a code repository it is important to identify the architecture of the shell which will  actually  run  the  installed
       packages, versus the architecture of the shell running the repository software.

COMMANDS

       platform::shell::identify shell
	      This command does the same identification as platform::identify, for the specified Tcl shell, in contrast to the running shell.

       platform::shell::generic shell
	      This command does the same identification as platform::generic, for the specified Tcl shell, in contrast to the running shell.

       platform::shell::platform shell
	      This command returns the contents of tcl_platform(platform) for the specified Tcl shell.
