[ronnie escobedo]

#!/bin/bash

############## MEncoder Chapter Encoder #########################
# author: ronnie r escobedo					#
# contact: rescobedo at mixsessions.com				#
# created: 12-11-2004						#
#								#
# -this script was created because I needed a better		#
#  method for encoding several chapters from several		#
#  different DVDs and not having to worry about			#
#  remembering the name of the last file			#
#								#
# -allows you to specify which chapters per dvd to encode	#
# -will automatically name the files using a number naming	#
#  convention							#
# Everything is well commented. The only necessary change	#
# are to 'videodir'. This is where all your encoded files	#
# will be saved. The other changes that must be made are	#
# to MEncoder. Remember to change -dvd-device, set your		#
# encoding quality, video filter and crop options.		#
#								#
#								#
# Run script with appropriate permissions. When you launch	#
# the script you will be prompted to enter the chapters		#
# for encoding. Enter 'ALL' the chapters you would like to	#
# encode. The prompt will only run once.			#
#								#
# When the file encoding is complete Mplayer will play the	#
# audio of the 1st avi file encoded to let you know all		#
# encoding is complete. You can comment out Mplayer or		#
# specify your own audio file.					#
