#!/bin/bash
#
# Version 1.9 2006-04-28
#
# Author: Mike Constabel
# VDR-Portal: vejoun
# EMail: vejoun @ toppoint.de
#
# MANUAL:
# -------
# 1.
# If you run VDR as user, you need in /etc/fstab the option "user" for your DVD mountpoint.
#
# Example:
# /dev/hdc /media/cdrom iso9660 defaults,ro,user,noauto 0 0
#
# 2.
# If you use a VFAT partition for your video-data, you must configure sudo to allow the
# VDR-user to execute mount and umount as root. To edit sudoers run 'visudo' command as root.
#
# Example:
# # Cmnd alias specification
# Cmnd_Alias SYSTEM = /bin/mount, /bin/umount
# # User privilege specification
# vdr ALL=(root) NOPASSWD: SYSTEM
#
# With a vfat partition some things doesn't work: resume, marks
#
# 3.
# For dvd-in-drive detection compile isodetect.c and put it into the $PATH,
# usually /usr/local/bin/
# You find isodetect.c in the extrecmenu plugin source package.
#
# 4.
# Tools needed: mount, awk, find, test, stat
# Optional tools: isodetect
#
# 5.
# If you have some DVDs with the index.vdr only on DVD, you don't use vfat and you
# want to see the recording length in the menu, you can switch GETLENGTH to 1 and
# the script will create a length.vdr for you.
#
# 6.
# Exitcodes:
#
# exit 0 - no error
# exit 1 - mount/umount error
# exit 2 - no dvd in drive
# exit 3 - wrong dvd in drive / recording not found
# exit 4 - error while linking [0-9]*.vdr
# exit 5 - sudo or mount --bind / umount error (vfat system)
#
# HISTORY:
# --------
# 1.9 - use "sudo mount --bind" for mounting if filesystem is vfat
# - automatic fallback to 'sudo' and 'mount --bind' if filesystem is vfat
# - mounting more failure tolerant
# - added MANUAL part in script
# - length.vdr creation, you must not use it ;)
#
# 1.8 - remove sudo, is not necessary
# - on mount, if already mounted try to umount first
# - logging per syslog, see $SYSLOG
#
#<Configuration>
# Mountpoint, the same as in fstab
MOUNTPOINT="/media/cdrom" # no trailing '/'
# Eject DVD for exit-codes 2 and 3 (no or wrong dvd). 1 = yes, 0 = no.
EJECTWRONG=0
# Eject DVD after unmounting. 1 = yes, 0 = no.
EJECTUMOUNT=0
# Log warnings/errors in syslog. 1 = yes, 0 = no.
SYSLOG=0
# Create a length.vdr after mounting the dvd for the played recording. 1 = yes, 0 = no.
# Only for non-vfat and with index.vdr only on dvd.
GETLENGTH=0
#</Configuration>
# No changes needed after this mark
