# Based on the ffmpegprogress bar from: http://handybashscripts.blogspot.com/2011/01/ffmpeg-with-progress-bar-re-work.html
# which was based on my initital progress script - circle of life and all that ;)
# version 2.0
# 07.04.2011
# now uses apparently better progress detection, based on duration of overall video and progress along the conversion
####################################################################################
# USAGE #
# 1) Run the script with the name of the file to be converted after the name of the script 
# (e.g. ./ffmpeg-progress.sh "My Awesome Video.mpg)
# 2)   Pipe to zenity to show progress
# (e.g ./ffmpeg-progress.sh video.mpg | zenity --auto-close --time-remaining --progress
###################################################################################
# Please adjust the following variables as needed. 
# It is recommended you at least adjust the first variable, the name of the script
