|
#
|
|
# 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, sed
|
|
# 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.
|
|
# If something went wrong, set DEBUG=1 and send me the file which is defined in $DEBUGLOG.
|
|
# Use VDR-Portal or EMail.
|
|
#
|
|
# 7.
|
|
# 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:
|
|
# --------
|
|
# 2006-07-14: Version 2.3-beta
|
|
#
|
|
# - should be compatible with ash, busybox
|
|
# stays beta until someone confirm this or 2.4 comes
|
|
#
|
|
# 2006-06-13: Version 2.2
|
|
#
|
|
# - at mount, if third parameter is not given, take last part of path
|
|
#
|
|
# Version 2.1
|
|
#
|
|
# - Fixed bug in testing if dvd is mounted
|
|
# - more DEBUG=1 output
|
|
#
|
|
# Version 2.0
|
|
#
|
|
# - more logging
|
|
# - check if mountpoint and device exists
|
|
# - Debug Log in file $DEBUGLOG if $DEBUG is 1, for easier error reporting
|
|
#
|
|
# Version 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 ;)
|
|
#
|
|
# Version 1.8
|
|
#
|
|
# - remove sudo, is not necessary
|
|
# - on mount, if already mounted try to umount first
|
|
# - logging per syslog, see $SYSLOG
|
|
