-----
-
-!! 2. Requirements
-
-
-
-This HOWTO assumes you have:
-
-
-* Linux kernel v2.2.x or greater. A kernel with DVD ioctls is prefered.
-*
-
-* XFree86 3.3.X or 4.x
-*
-
-* A DVD-ROM/RAM/RW drive supported in Linux (most are)
-*
-
-* A decent knowledge of bash and english
-*
-
-
-
-

-
-!! 3. Files
-
-
-First things first, you need to get a kernel with MTRR (more on this later)
-and DVD ioctl support. While MTRR's have been in the kernel since 2.2.11
-(correct me if I'm wrong), you will probably need to update your kernel
-to get DVD ioctls. There are two ways to skin this cat, you can
-either download a development kernel (v2.3.x), or patch a stable release
-kernel (v2.2.x), the patches are at
-http://www.kernel.dk/,
-and the kernel can be found on your favorite mirror of
-ftp://ftp.kernel.org/.
-
-
-Next, you need to get the LiViD utilities. This can be done two ways:
-
-
-
-
-
-* Get the LiViD utilities from CVS, so you can update it as it is being
-updated by the developers. (recommended)
-*
-
-
-
-
-
-The following commands will retrieve them (you can use -d parameter
-instead of setting CVSROOT if you want):
-# mkdir ~/livid
-# cd ~/livid
-# export CVSROOT=:pserver:anonymous@cvs.linuxvideo.org:/cvs/livid
-# cvs login
-(Logging in to anonymous@cvs.linuxvideo.org)
-CVS password:
-There is no password for anonymous, just press enter.
-# cvs -z3 co -P ac3dec mpeg2dec oms
-They should download into their respective directories.
-
-
-
-
-
-
-*
-If you don't like CVS or can't access it due to firewall issues, you
-can download the most recent nightly tarball of LiViD tools at
-http://www.linuxvideo.org/developer/dl.phtml
-*
-
-----
-
-!! 4. Installation
-
-!!4.1 Kernel
-
-
-
-Kernels at least as recent as 2.2.16 or 2.4 series should
-already have DVD ioctl support, so you just need to make sure you
-have MTRR support enabled in the kernel configuration, and then compile
-and install it as you normally would.
-
-
-
-If you want to patch your exisiting older kernel, start by going to
-http://www.kernel.dk/
-and downloading the correct patch for your kernel.
-
-
-
-
-
-If don't know how to install or patch your kernel, you should go read
-the Kernel HOWTO at
-http://howto.tucows.com/LDP/HOWTO/Kernel-HOWTO.html
-!!4.2 LiViD Utilities
-
-
-
-To install the LiViD utilities, you need to make sure you have /usr/local/lib
-somewhere in /etc/ld.so.conf.
-
-
-DVD playback only requires OMS to be built. It builds ac3 and mpeg2 codecs
-by itself. However, feel free to play with the standalone codecs if you
-wish. The following commands should compile and install the LiViD
-utilities on your system. If you have problems, please see the "Problems"
-section.
-
-
-
-
-ac3dec: (optional)
-# cd ~/livid/ac3dec
-# ./autogen.sh
-# make
-# make install
-mpeg2dec: (optional)
-# cd ~/livid/mpeg2dec
-# ./autogen.sh
-# make
-# make install
-oms:
-# cd ~/livid/oms
-# ./autogen.sh
-# ./configure
-# make
-# make install
-
-
-
-There are some extra options that can be used. They are placed
-as arguments to the ./configure script. OMS has --enable-devel which
-will enable some development and experimental features in the code.
-Standard autoconf parameters such as --prefix can be used if you wish
-to install somehwere other than /usr/local. For instance to install
-in a subdir of the source dir you could do:
-
-# ./configure --prefix=`pwd`/inst
-
-
-
-Run ./configure --help to get a complete listing of options. If you
-install X in an odd location (for instance you have XFree86 3.3.x and 4.x
-installed at the same time) you may need the --x-includes and --x-libraries
-options.
-
-
-Now the necessary LiViD utilities should be installed. The next section is
-not required, but if you use the "pipes" plugin, you will need to make some
-special fifo pipes for the DVD data to travel over. These can be made with
-the following commands (if they don't already exist):
-
-
-
-
-
-
-
-# mkfifo /tmp/video
-# mkfifo /tmp/audio
-
-
-
-Another method of controlling the data available in the oms_devel version is to use raw I/O, which is available in the latest linux kernels. If you don't have these, data will be read from the standard device. Using raw I/O is recommended, but not necessary. If they do not exist, create two devices as follows:
-
-# mknod /dev/rawctl c 162
-# mknod /dev/raw1 c 162 1
-
-
-
-
-One last thing to do. OMS needs /dev/dvd to be a symlink to where
-your DVD drive resides, such as /dev/hdb1 or /dev/scd0. If it is at
-/dev/cdrom, you would create the link by typing:
-
-
-
-
-# ln -s /dev/cdrom /dev/dvd
-
-
-
-It is generally a good idea not to make a symlink to a symlink, because it
-adds unnecessary I/O. Replace /dev/cdrom with the
-correct device that your dvd drive is on.
-----
-
-!! 5. Playing
-
-
-First you need a config file. Copy doc/config.sample from oms source directory to .oms/config in your home directory. Edit the values to reflect the drivers, skin, device, etc you want to use.
-
-
-Expect lots of text to scroll by. This is still development code. If you see lots of text, but no video window you may have a mistake in your config file. Check to make sure you are using the right plugins and devices.
-
-
-To play a DVD, you need to be running X in 16-bit color mode. With the
-DVD in the drive, type:
-
-
-
-
-# oms
-
-
-
-There is a pipe method available in older OMS versions that uses the
-fifo's created earlier. Most people can ignore this. To use pipes
-type:
-
-# ac3dec /tmp/audio& mpeg2dec /tmp/video& oms
-
-
-
-ac3dec and mpeg2dec may need to be killed by hand using this method.
-
-
-
-If all has gone well, some text should fly by, followed by it asking
-you if you want it to look up the name of the disk in the DVDDB.
-It is safe to say yes. Then, the oms panel should pop up. Click the
-playlist button, then the scan dvd button, then play.
-----
-
-!! 6. Additional Stuff
-
-!!6.1 Setting up MTRR's
-
-
-
-
-
-** Note to Matrox video card owners **
-If you have matroxfb compiled into the kernel,
-chances are that your MTRR's are already set
-up. You can probably just skip this section.
-
-
-
-Setting up your MTRR's can increase video performance quite
-a bit in some cases, so it is a good idea to do it. First,
-you need to make sure you have MTRR support in your kernel by
-typing:
-
-
-
-
-# ls /proc/mtrr
-
-
-
-
-If it tells you that there is no such thing as /proc/mtrr, you
-need to recompile your kernel with MTRR support (it is under
-"Processor type and features" in menuconfig).
-
-
-
-Once you know MTRR is working, you need to know the base memory
-address of your video card, and how much video ram it has. The
-easiest way to do this is to look at the output of X as it starts
-up. Because the output usually scrolls off the screen and is
-lost when it switches to a different tty, you need to redirect the
-output of X to a file (xoutput) so you can go back and look at it
-to get the needed values. This can be done by typing:
-
-
-
-
-# startx 2> xoutput
-
-
-
-
-The line having the needed information is probably somewhere
-towards the middle of xoutput, and should look something like:
-
-
-
-
-(--) SVGA: PCI: NVidia Riva TNT2 rev 17, Memory @ 0xee000000, 0xe2000000
-
-
-
-
-Once you have located that, write down the last memory address, in
-this case 0xe2000000. Depending on your hardware, you may or may not
-have multiple memory addresses shown, so don't worry if yours looks a
-little different. With this information recorded, you can delete
-xoutput.
-
-
-
-Next you need to create a new MTRR. In order to do that, you have
-know how much ram your video card has in hex. Here are some common
-values:
-
-
-
-
-4MB -- 0x400000
-8MB -- 0x800000
-16MB -- 0x1000000
-32MB -- 0x2000000
-
-
-
-
-To add the MTRR, type:
-
-
-
-
-# echo "base=0xe2000000 size=0x2000000 type=write-combining" >| /proc/mtrr
-
-
-
-
-Substituting "0xe2000000" and "0x2000000" with the base address and amount
-of video ram specific to your system.
-
-
-
-Now you should have MTRR set up, and just to make sure, type:
-
-
-
-
-# cat /proc/mtrr
-
-
-
-
-And you should get output that looks remotely similar to:
-
-
-
-
-reg00: base=0x00000000 ( 0MB), size= 128MB: write-back, count=1
-reg01: base=0xe2000000 (3616MB), size= 32MB: write-combining, count=1
-
-
-
-
-Again, the number of entries will probably be different from these,
-don't sweat it.

-
-!! 7. Problems
-
-!! 7.1 Run time errors
-
-
-
-This is a (small) list of known run-time errors.
-
-!Illegal Instruction Error
-
-
-If you use a non-Intel chip (K6 especially), and you are getting
-this error when you try to run mpeg2video, try editing
-nist/configure.in, lines 129 and 130:
-
-
-
-
-CFLAGS="$CFLAGS -DHAVE_MMX -DLINUX -march=i686 -fschedule-insns2 -malign-doub
-CXXFLAGS="$CXXFLAGS -DHAVE_MMX -DLINUX -march=i686 -fschedule-insns2 -malign-
-
-
-
-
-replace "-march=i686" in both with "-march=i586", and then recompile
-and reinstall.
-
-!! 7.2 Compilation errors
-
-
-
-This is a running list of common compilation errors that have known
-fixes.
-
-!`dvd_struct' undeclared...
-
-
-The most frequent problem people have when trying to compile these utilities stems from oms looking in the wrong place for the kernel headers. By default, it uses /usr/include/
[[linux|asm
], but those headers are from a stable kernel so that when you compile a normal program, it will be using older headers. OMS needs to use headers with dvd ioctl support. If things are set up wrong many things are undeclared and compilation fails. The best way to fix this is to use the configure option --with-kernel-headers=(path to headers). Another way is to adjust which headers are in the default location.
-
-
-
-
-These commands should do it:
-# mkdir /usr/include/old
-# mv /usr/include/linux /usr/include/old/linux
-# mv /usr/include/asm /usr/include/old/asm
-# mv /usr/include/scsi /usr/include/old/scsi
-# ln -s /usr/src/linux/include/linux /usr/include/linux
-# ln -s /usr/src/linux/include/scsi /usr/include/scsi
-# ln -s /usr/src/linux/include/asm /usr/include/asm
-
-
-!Can't determine absolute dir of '../../../../src/plugin/codec/mpeg2dec/.libs'
-
-
-Another common error is with the oms/src/plugin/codec/mpeg2dec/.libs
-directory. For some reason or another, this directory does not
-exist, and it needs to for compilation. To fix it, just make the
-directory:
-
-
-
-
-# mkdir src/plugin/codec/mpeg2dec/.libs
-
-
-!Can't find libXv.so or libXxf86dga.so
-
-
-Xfree86 4.x doesn't build shared libs for Xv and Xxf86dga. However, the
-shared lib setup OMS uses needs them. Build them as follows in your
-favorite lib dir:
-
-
-
-
-# ld --whole-archive -shared -o libXv.so libXv.a
-# ld --whole-archive -shared -o libXxf86dga.so libXxf86dga.a
-
-
-!Failure via segfault for no apparent reason
-
-
-Sometime you have old libraries laying around that are used by mistake.
-This will cause unwanted behavior such as crashing. Get rid of old
-libraries from /usr/local/lib or wherever you put them and things
-should work.
-
-!! 7.3 Broken stuff
-
-
-
-Features that don't currently work as intended:
-
-
-* The chapter seek buttons may fail.
-*
-
-* The play/pause/stop buttons may fail to work.
-*
-
-* Audio/video may skip or sound "choppy". This is due to proper syncronization and framedropping not being implemented yet.
-*
-
-
-!! 7.4 Other errors
-
-
-
-If your problem isn't listed
here, then likely the current CVS
-code has a bug in it or is missing a feature. You can either
-hope it will be fixed and update CVS every so often or subscribe
-to the mailing lists and report the bug or request a feature.
-To subscribe send a blank email to
-livid-user-subscribe@linuxvideo.org.
-----
-
-!! 8. To Do
-
-
-
-
-
-* Makefile options (HAVE_MMX, HAVE_3DNOW, etc)
-*
-
-* proper architecture detection (compile time and runtime)
-*
-
-* add easy MTRR stuff (framebuffer)
-*
-
-* add need for region coding to be set on most drives: www.linuxtv
.org/dvd
-*
