><P
>
The xine engine is a free media player engine. It comes in the form of
a shared libarary and is typically used by media player frontends
and other multimedia applications for playback of multimedia streams
such as movies, radio/tv network streams, DVDs, VCDs.

><P
> First of all be sure that your question is really not covered here and
that you haven't just been a bit too lazy to read through all of this
text. ;-). Also check out the xine HOWTO and documentation specific to
the frontend (e.g. <B
CLASS="COMMAND"
> xine-ui </B
> or <B
CLASS="COMMAND"
> gxine </B
> or
<B
CLASS="COMMAND"
> totem </B
>).

Please provide some info about your setup so people have a chance to
help you, e.g. include information about your audio/video hardware
and drivers you use, operating system, cpu type and some console
output/any error messages. Also include command line parameters you
have specified and information about the type of stream you're
trying to play back. Also very important is the version of xine
you're using and information about any additional plugins you
may have installed on your system.

>What are those xine-lib, xine-ui, gxine, ... modules in cvs for?</H2
><P
> Some time ago xine just became too complex to be just one big program.
Therefore it was split into two major parts.
</P
><P
> xine-lib is simply speaking the engine of xine. It contains all plugins
and is necessary to run anything that relies on xine (this is the part that
is covered in this FAQ).
</P
><P
> Then there are frontends - applications that use xine. The most
common frontend is that of a media player. There are currently
two frontends being developed in the xine project, xine-ui (skinned
dvd-player style frontend directly based on xlib) and gxine,
a desktop media-player style frontend using the standard gtk widget set
and comes with a mozilla browser plugin.
External projects like sinek and totem develop additional frontends.
In the future you will likely see more and different types of apllications
being developed which will use the xine engine for video processing
and other multimedia purposes.
</P
><P
> If you simply want a media/dvd player, you'll need to install xine-lib
first and then choose and install a player frontend like xine-ui or gxine.
</P
><P
> Other modules in CVS: <TT
CLASS="FILENAME"
>xine-plugin</TT
> a mozilla browser plugin
for streaming media playback using xine (at the time of this writing
unmaintained and somewhat obsoleted by gxine's browser plugin),
<TT
CLASS="FILENAME"
>xine-www</TT
> the
xine project website sources.

>Where can I find pre-compiled binaries, e.g. RPMs?</H2

> The xine project does not provide pre-compiled binaries for legal
reasons (some parts of xine may be covered by patents in some countries).
Some OS projects/vendors (e.g. debian, freebsd, ...) offer binaries
for their distributions - please contact them for further info.
You can also find links to third parties providing xine RPMs on
the xine homepage :

><P
> First of all an official and stable release of gcc. Also be aware
that patched gcc versions may break parts of xine and are therefore
not supported by the xine project.
</P
><P
> Furthermore you'll have to use GNU make to compile xine. On most GNU/Linux
systems "make" is GNU make - on other platforms use "gmake" instead.
Also, zlib iss required (including the appropriate header files, which are
often found in a package called zlib-devel or similar.)
</P
><P
> If you want to compile xine from CVS, you'll need to have the autobuild tools
installed (automake, autoconf and libtool - in recent versions).
</P
><P
> Frontends might need additional libraries, e.g. for gxine you'll need to have
GTK installed. Make sure you have not only the shared libraries themselves
but also the header files (often packaged seperately as so-called -dev packages)
on your system.
</P
><P
> Some plugins that come with the xine engine need additional libraries (otherwise
they will not be built). For example, libogg and libvorbis (plus their include files)
are needed for ogg/vorbis support.
</P

DVD plugin that should be able to handle any unencrypted,

</P
><P
> To get DVD playback working, first make sure you have
a symlink <TT
CLASS="FILENAME"
>/dev/dvd</TT
> pointing to your
DVD device on your system. For example, if your DVD drive
is the master ide drive on the second IDE channel,
<TT
CLASS="FILENAME"
>/dev/dvd</TT
> should point to
<TT
CLASS="FILENAME"
>/dev/hdc</TT
>. Please note that if you
are using the ide-scsi emulation on your system, it is
likely that you dvd drive got mapped to a scsi device
node even though it is an ide drive. In that case first
check out you boot/kernel logs (or run <B
CLASS="COMMAND"
> cdrecord -scanbus </B
>)
to find out which device it got mapped to and set the
symlink accordingly (should be something like <TT
CLASS="FILENAME"
>/dev/scd0</TT
>,
<TT
CLASS="FILENAME"
>/dev/scd1</TT
>, ... in that case).
Also make sure you (as a user) have sufficient (read) permissions
on your dvd drive (this could mean you either have to change the device
permissions or add your user to a special group
(e.g. <B
CLASS="COMMAND"
>addgroup cdrom username</B
>),
depending on your setup and/or distribution.
</P
><P
> It is highly recommended to switch DMA mode on for your DVD drive
(without it even very recent machines will have trouble producing
smooth video output). Use a command like
<B
CLASS="COMMAND"
>hdparm -d 1 device</B
>
on your dvd device. Please note that even if you're using ide-scsi
you will have to set the dma flag on the ide device node (e.g.
<TT
CLASS="FILENAME"
>/dev/hdc</TT
>), not the mapped <TT
CLASS="FILENAME"
>/dev/scd</TT
>
scsi device.

> To be able to play back encrypted dvds you need to have
libdvdcss installed on your system (please check if this is legal where
you live).
</P

Newer (post-2000) dvd drives (so-called RPC-2 drives) check the dvd
region, which means they'll prevent you from playing back dvds that have
a different region code from what the drive is set up for (most drives
come with a factory setting of region 0 so they can only play back
region 0 dvds and there are not many of those available). The easiest
way to handle this is to use the regionset utility from

buttons or menu entries that start dvd playback immediately.

button or start xine from the command line.

by the many redirectors that are often placed around the actual url.
Use wget to download any http://-style urls and use less to look inside

Your soundcard does not keep it's sampling frequency accurately

can help here.

deliver overdue frames. Imagine if it finished decoding the frame
tagged for displaying at 11:30 but xine clock marks 11:31. When this

to recover. Not every decoder may support this feature.

be the disk access operation, which may halt the system for a few
miliseconds without DMA. See performance section tips above.

> However some users may want to explore better the available hardware
capabilities (eg. syncing frame drawing with monitor refresh).
Also some Xv drivers contain slow copies and accessing the video card
directly may yield performance gains.
</P
><P
> Drivers that access hardware directly includes VIDIX (warning: requires
root priviledges) and SyncFB (requires kernel helper - Matrox only).
User may try one of those, but should be warned that with root access
they can cause the system to crash hard. The support is also limited to
a couple of graphics cards only.
</P

> Graphic workstations like SGI have usually a good support for OpenGL.
In that case, using OpenGL may be a better choice than XShm. However for
most desktop systems the performance of OpenGL will be quite bad.

> If you are using GNOME, chances are that this is caused by ESD. Now you
have two possibilities. Either deactivate ESD (temporarily) by right
clicking on the sound monitor applet and selecting "Place Esound in
standby" or just kill it. Then xine will use OSS audio output. The other
method is to make xine use ESD for audio output with:
<TABLE
BORDER="0"
BGCOLOR="#E0E0E0"
WIDTH="100%"
><TR
><TD
><PRE
CLASS="PROGRAMLISTING"
> gxine -A esd
</PRE

This may result in worse playback - exact syncronization is not possible
with esd, so using oss should be preferred.
</P
><P
> If you are using KDE, there is the possibility that the aRts sound
daemon is currently running and thus blocking your sound device. You
can check that by starting the aRts control (in your KDE menu it should
be under Multimedia). If it is running, you can either use the aRts
audio output plugin:
<TABLE
BORDER="0"
BGCOLOR="#E0E0E0"
WIDTH="100%"
><TR
><TD
><PRE
CLASS="PROGRAMLISTING"
> gxine -A arts
</PRE
></TD
></TR
></TABLE

Or you suspend the aRts daemon by checking the appropriate option in
your aRts control. (recommended)
</P
><P
> Newer versions of arts have an auto-suspend mode - this can lead to
some nondeterministic behaviour of xine if it is set up to use
the audio device directly. Using arts is recommended in that case,
however you will loose the ability to do four/five channel audio output.

But, to help you and of course to fix this, we need some information.
So, let's go through the checklist and maybe prepare a nice bug report
for the xine-user mailing list:
</P
><P
></P
><UL
><LI
><P
> did xine really crash (segfault) or did it hang (deadlock) ?
</P
></LI
><LI
><P

did and when you do it again it crashes again?)
</P
></LI
><LI
><P
> is that a specific media file or format which crashes xine? (have you
tried other files types?)
</P
></LI
><LI
><P
> check the console output (and include it in a bug report), maybe earlier
there is some output that points to the problem.
</P
></LI
><LI
><P
> Your X server just froze on you? unfortunately that's a known problem
with some chipsets and drivers (most commonly Savage chipsets) when
using Xv. You might want to try running <B

>
to see if the problem is related to the Xv driver. This will unfortunately
be much slower, as lots of things are now done
in software instead of hardware scaling/colour space conversion.
</P
><P

this for the Savage driver. If that works for you, please notify the xine crew at

><P

<TT

make sure you include a the above information (when applicable)
and also some information about your machine (operating system, cpu type and
speed, gfx card, sound card, ...) and please use a meaningfull subject
line ("xine bug" is bad, "xine fails to play this quicktime trailer in fullscreen mode"
ist much better).
