I.   ABOUT

   dvd::rip is a full featured DVD copy program written in Perl. It
   provides an easy to use but feature-rich Gtk+ GUI to control almost
   all aspects of the ripping and transcoding process. It uses the widely
   known video processing swissknife transcode and many other Open
   Source tools. dvd::rip itself is licensed under GPL / Perl Artistic
   License.

            "And note: it's spelled dvd::rip, and nothing else."

     _________________________________________________________________

   This chapter describes how you can get and install dvd::rip. You can
   try one of the several binary distributions or install it from the
   source.

[33]1.1 Binary distributions

   [ [34]Content ] [ [35]Top ]

   Installation of dvd::rip isn't that hard, but fulfilling the
   requirements actually is (simply because they are a lot ;). So you
   should first try a binary installation using the package manager of
   your Linux distribution. This should track all dependencies
   automatcially and speed up things significantly.

[36]1.1.1 Debian packages

   Christian Marillat builds video related Debian packages and publishes
   them on his website [37]http://marillat.free.fr/. You can use apt-get
   to install the packages if you add one of the following entries
   (depending on your distribution) to your /etc/apt/sources.list file:

deb http://marillat.free.fr/ testing main
deb http://marillat.free.fr/ unstable main

   You will find all packages to compile transcode on your own (if you
   need always the very latest versions), or can get binaries of
   reasonably recent transcode versions directly. The same applies to
   dvd::rip.

[38]1.1.2 SuSE packages

   Rainer Ley builds dvd::rip SuSE RPM's you can download from the
   contrib directory:

     [39]http://www.exit1.org/dvdrip/contrib/suse/

   On his homepage you find several video related RPM's, including
   transcode:

     [40]http://www6.informatik.uni-erlangen.de/~rainer/rpms/

[41]1.1.3 Mandrake packages

   Mandrake users can get actual dvd::rip and transcode RPM's from the
   Penguin Liberation Front lair.

     [42]http://plf.zarb.org/

[43]1.1.4 RedHat packages

   A kind RedHat user (who wants to stay anonymous) builds dvd::rip
   RedHat RPM's, you can download from the contrib directory:

     [44]http://www.exit1.org/dvdrip/contrib/redhat/

[45]1.1.5 RedHat-8.0-only packages

   Michel Alexandre Salim maintains an apt repository with the very
   latest snapshots of transcode and dvd::rip. It's for RedHat 8.0 only:

     [46]http://messlab.sourceforge.net

[47]1.1.6 gentoo packages

   You can get dvd::rip and transcode from the official gentoo package
   repository:

     [48]http://www.gentoo.org/packages/media-video/dvdrip.html

[49]1.2 Source download

   [ [50]Content ] [ [51]Top ]

[52]1.2.1 dvd::rip tarball download

   You can download dvd::rip sources from this server or all stable
   releases from any CPAN mirror.

   Local download of the latest stable release:

     [53]Video-DVDRip-0.50.3.tar.gz

   CPAN download directory: ([54]list of mirrors)

     [55]http://www.cpan.org/CPAN/modules/by-authors/id/J/JR/JRED/

   You can download older versions from here:

     [56]http://www.exit1.org/dvdrip/dist/
     [57]http://www.exit1.org/dvdrip/dist/pre/

[58]1.2.2 CVS access

   This is mainly intended for developers. This CVS repository is only a
   read only mirror of my main repository. It's updated manually when I
   publish releases or pre-releases, so there is no advantage for normal
   users compared to downloading the tar balls (besides making it easier
   using "cvs update" ;)

   Since development of dvd::rip is divided into two branches, you get
   the current (unstable) version, if you don't specifiy a release tag.
   If you want to access a stable version, add -r rel-MAJOR-MINOR-PATCH
   to your cvs checkout command (example: for 0.48.5 this is -r
   rel-0-48-5). All subsequent updates will stay on this branch (here:
   0.48). The easiest way of switching to another branch, is creating a
   new checkout using the corresponding release tag.

   Root                            Module Unstable tag Stable tag
   :pserver:cvs@cvs.exit1.org:/cvs dvdrip none         rel-MAJOR-MINOR-PATCH

[59]1.2.2.1 CVS examples

   Checkout a stable/bugfix version (here 0.48.5) with:

cvs -z9 -d :pserver:cvs@cvs.exit1.org:/cvs checkout -r rel-0-48-5 dvdrip

   Checkout the current development version with:

cvs -z9 -d :pserver:cvs@cvs.exit1.org:/cvs checkout dvdrip

   Update a checkout - created using one of the commands above - with:

cd dvdrip; cvs -z9 update

[60]1.3 Requirements

   [ [61]Content ] [ [62]Top ]

   dvd::rip is a Gtk+ based program written in Perl, using the video
   processing tool transcode and many other tools for the internals. So
   you first have to comply some prerequisites before installing
   dvd::rip.

   dvd::rip expects all command line tools mentioned here to be found in
   the standard search PATH.

[63]1.3.1 Brief overview

   This table gives a brief overview about the tools used by dvd::rip
   (everything but Perl modules - see chapters below for more information
   about them). Most tools are optional - the corresponding dvd::rip
   modules are just switched off, if you don't have them.

   But you need at least the tools marked mandatory, otherwise dvd::rip
   will complain with an error message on startup. You can get also a
   dvd::rip window listing this information, refer to the
   [64]corresponding chapter in the documentation for details.

   Tool Comment Mandatory Suggested Minimum Maximum
   transcode dvd::rip is nothing without transcode Yes 0.6.3 0.6.2 -
   ImageMagick Needed for preview image processing Yes 5.5.3 4.0.0 -
   pstree Needed to determine child PID's Yes 21.2 18 -
   subtitle2pgm Needed for subtitles No 0.3 0.3 -
   rar Needed for compressed subtitles No 2.71 2.71 2.99
   mplayer Needed for subtitle vobsub viewing No 0.90 0.90 -
   ogmtools Needed for OGG/Vorbis No 0.972 0.960 -
   mjpegtools Needed for (S)VCD encoding No 1.6.0 1.6.0 -
   cdrdao Needed for (S)VCD burning No 1.1.7 1.1.7 -
   vcdimager Needed for (S)VCD burning No 0.7.12 0.7.12 -
   mkisofs Needed for AVI/OGG burning No 2.0 1.15 -
   cdrecord Needed for AVI/OGG burning No 2.0 0.7.12 -
   xine Can be used to view DVD's/files No 0.9.15 0.9.13 -
   fping Only for cluster mode master No 2.4 2.2 -

   The following chapters describe the needed tools in detail, including
   information on how to get them. Additionally to the table above all
   need Perl modules are described also.

[65]1.3.2 Perl 5.6.0 or better

   You need a recent Perl version on your system. Perl 5.8.0 is
   recommended, 5.6.0 and 5.6.1 should work also. dvd::rip won't start
   with Perl versions prior 5.6.0. Actual distributions ship minimum
   5.6.1, so this shouldn't be a real problem, anyway.

[66]1.3.3 Perl Gtk Module

   For its GUI component dvd::rip needs the Perl Gtk module, which
   presumes Gtk+ version 1.2 or higher. I tested dvd::rip with Perl Gtk
   0.7008.

   You can find the Gtk module on CPAN, e.g.:

     [67]http://www.perl.org/CPAN/modules/by-module/Gtk/

   Note:
   Perl Gtk detects your installed Gtk libs and build sub components only
   if the correspondent Gtk library was found.

   dvd::rip needs the Gtk::Gdk::Pixbuf component which needs gdk-pixbuf
   to be installed on your system. So first make sure, that gdk-pixbuf is
   installed. Then install Perl Gtk and everything should work as
   expected.

[68]1.3.4 transcode

   dvd::rip delegates all the low level video processing to transcode,
   which can be obtained here:

     [69]http://www.theorie.physik.uni-goettingen.de/~ostreich/transcode
     /

   dvd::rip should work with the latest transcode releases (at least with
   the latest major stable release). Otherwise correspondent notes are
   added to the release notes resp. posted on the homepage.

   If you plan to create (S)VCD's you must compile transcode with the
   mjpeg export filter module. transcode's internal bbmpeg filter isn't
   supported yet.

   Note: For almost any Linux distribution exist binary transcode
   packages. Compiling transcode sometimes isn't an easy task, in
   particular if you are not familiar with building packages, which have
   lots of dependencies. So you should try binary packages first. Refer
   to the [70]binaries section for details.

[71]1.3.5 Image Magick

   For image processing dvd::rip uses the widely distributed software
   package Image Magick, at least the programs identify and convert
   should be installed on your system.

   If your Linux distribution does not ship Image Magick, you can find it
   here:

     [72]http://www.imagemagick.org/

[73]1.3.6 ogmtools

   dvd::rip has support for generating audio / video ogg streams (often
   known as OGM streams). You need a recent version of ogmtools for that
   to work:

     [74]http://www.bunkus.org/videotools/ogmtools/index.html

[75]1.3.7 subtitleripper

   To get subtitles with dvd::rip you need a recent version of the
   subtitleripper package. It's shipped with transcode in the
   contrib/subrip directory or you can fetch it from the subtitleripper
   homepage:

     [76]http://sourceforge.net/projects/subtitleripper

[77]1.3.8 mplayer and/or xine (with a DVD plugin)

   If you have mplayer or xine (with the d4d or dvdnav plugin) installed,
   you can preview selected DVD titles/chapters with the appropriate
   audio channels.

   You can download xine and mplayer from here:

     [78]http://xine.sourceforge.net/
     [79]http://www.mplayerhq.hu/

[80]1.3.9 CD burning tools

   If you want to use dvd::rip's [81]CD burning module, you must have the
   following tools installed:

     [82]mkisofs
     [83]cdrecord
     [84]vcdimager
     [85]cdrdao

[86]1.3.10 rar (for vobsub compression)

   MPlayer supports vobsub files compressed with rar, but you need a 2.x
   version, 3.x and higher doesn't work. You can get a 2.x version
   locally from here:

     [87]http://www.exit1.org/dvdrip/contrib/rarlnx271.sfx.bin

   I suggest to install the binary to e.g. /usr/local/bin. Then configure
   this path using the [88]Preferences dialog.

[89]1.3.11 Additional requirements for cluster mode

   Some additional Perl modules and command line tools are needed for the
   cluster mode.

[90]1.3.12 Perl modules

   Cluster mode needs the Storable and Event Perl modules. Check if your
   distribution ships them already. If not, you can find them on CPAN:

     [91]http://www.perl.org/CPAN/modules/by-module/Storable/
     [92]http://www.perl.org/CPAN/modules/by-module/Event/

[93]1.3.13 fping and pstree

   The dvd::rip cluster control daemon uses fping to check if nodes are
   online and pstree to get information about specific child processes.
   Both tools should be shipped with your Linux distribution (fping
   sometimes isn't, but you can get it here: [94]http://www.fping.com/).

   Note: Matthias Riese told me that there are IPv6 fping packages which
   don't support IPv4, what's most likely not what you want, so pay
   attention to get the right version ("ipv6" should not occur in the
   package name).

   dvd::rip expects fping to be installed set-uid root (because you
   hopefully don't run dvd::rip as root ;), which is not the default for
   most distributions. Please set the set-uid flag by typing this command
   as root:

chmod u+s /usr/sbin/fping

   If fping is installed in another location, set a symlink to
   /usr/sbin/fping, because dvd::rip expects it there.

   Note: These steps are necessary only on the computer, where the
   cluster control daemon runs. All slave nodes of a dvd::rip cluster
   only need transcode installed, dvd::rip or any packages mentioned here
   aren't needed there.

[95]1.4 Install from source

   [ [96]Content ] [ [97]Top ]

[98]1.4.1 Install dvd::rip

   This is quite easy, if you have managed installing the packages
   mentioned above... ;)

   [99]Download the .tar.gz archive of the dvd::rip version you want to
   install. Then extract the file, change into the created directory,
   generate the Makefile and execute make:

# as a normal user
tar xfz Video-DVDRip-0.50.3.tar.gz
cd Video-DVDRip-x.xx
perl Makefile.PL
make
make test

   If the "make test" reported no errors, you can install the files into
   your Perl library path. Usually you must be root to do this:

# become root
su
make install

   You can ommit the "make install" step. But then you can execute the
   'dvdrip' binary only from the build directory and must put "." into
   your PATH, otherwise dvd::rip can't find its files.

[100]1.4.2 Update dvd::rip

   Updating is just like installing. The only thing you should be aware
   of is switching the underlying Perl version. This way you easily can
   get two versions of dvd::rip installed in your system, because
   dvd::rip installs its libraries in your Perl library directory. Such a
   installation mixing isn't recommended unless you know exactly what
   you're doing. So it's better to remove the old version from the old
   Perl directory if you change the Perl version.
   Read the Changes file!

   I strongly suggest you reading at least the latest change log entry of
   the Changes file, resp. all entries of the versions you probably
   skipped in case of an update. It contains important release notes,
   e.g. about compatibility issues, and all relevant changes from release
   to release.

   Note:
   Changes on the unstable branch are logged in the file
   Changes.unstable.

[101]1.4.3 Multiple dvd::rip versions in parallel

   It's possible to use several dvd::rip versions in parallel on your
   system, but you can install only one version using make install into
   your system directories.

   Just extract another dvd::rip version you want to use somewhere, enter
   the created directory (Video-DVDRip-x.xx) and execute perl Makefile.PL
   && make here (no make install). Add the actual directory to your PATH
   (export PATH=.:$PATH) and you can start this version with ./dvdrip
   from this directory. All files and libraries located in the actual
   distribution directory will be used. The . in PATH is neccessary,
   otherwise some dvd::rip helper binaries may be taken from another
   place.

tar xvfz Video-DVDRip-0.50.3.tar.gz
cd Video-DVDRip-x.xx
perl Makefile.PL && make
export PATH=.:$PATH
./dvdrip

V.   MAILING LIST

   If you want to discuss usage, problems and suggestions with other
   dvd::rip users, you should subscribe to the dvdrip-users mailing list.
   This list is low traffic and announces, patches etc. will be posted
   here, too.

   The language of the mailing list is english.

This is closed mailing list: subscribe before posting.

   The list is closed to prevent members from getting flooded by spam. So
   you have to subscribe before posting. Postings from non subscribed
   users may be discarded without notification! Also you must use the
   correct sender address, because the mailing list program has no idea
   of your alternative mail addresses.

   Before posting any questions or bug reports: please first check the
   [3]documentation, in particular the [4]FAQ.

     * [5]Mailing list subscription
     * [6]Searchable mailing list archive

   IMPORTANT NOTE: please don't post any illegal stuff here, e.g.
   requests for movie downloads or similar stuff! Members breaking this
   simple rule will be removed immediately.

   Because dvd::rip is highly transcode related, I suggest subscribing to
   the [7]transcode-user mailing list, too.

VII. CHANGES
   $Id: Changes,v 1.131.2.6 2003/02/17 22:22:16 joern Exp $

   Revision history and release notes for dvd::rip.

   0.50.3 [stable branch] Mon 17 Feb 2003, joern
	Bugfixes:
	- Dropped the pstree dependend stuff completely. Now ps
	  is used, using Posix conform options only, so this should
	  work on most systems without problems.
	- Thanks to Ron Smits, who reported a problem with a few
	  zombie processes per dvd::rip session on a Slackware system.
	  After about an hour of IRC chatting we found a solution
	  for it ;)
