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

fakenect-record

FAKENECT-RECORD(1)						libfreenect manual						FAKENECT-RECORD(1)

NAME

       fakenect-record - program to save dumps from kinect to file

SYNOPSIS

       fakenect-record [-h] [-ffmpeg] [-ffmpeg-opts options] outputdir

DESCRIPTION

       fakenect-record dumps the output of the kinect in outputdir folder. It saves the acceleration, depth, and rgb data as individual files with
       names in the form "TYPE-CURRENTIME-TIMESTAMP" where:

	* TYPE is either (a)ccel, (d)epth, or (r)gb

	* TIMESTAMP corresponds to the timestamp associated with the observation (or in the case of accel, the last timestamp seen)

	* CURRENTTIME corresponds to a floating point version of the time in seconds.

       The purpose of storing the current time is so that delays can be recreated exactly as they occurred.  For RGB and DEPTH the dump is just
       the entirety of the data provided in PPM and PGM formats respectively (just a 1 line header above the raw dump).  For ACCEL, the dump is
       the "freenect_raw_tilt_state".  Only the front part of the file name is used, with the rest left undefined (extension, extra info, etc).

       A file called INDEX.txt is also output with all of the filenames local to that directory to simplify the format (e.g., no need to read the
       directory structure).

       Once started, the program will continue to acquire data from the kinect.  When you want to stop it, hit Ctrl-C and the signal will be
       caught, runloop stopped, and everything will be stored cleanly.

OPTIONS
