<H1><A NAME="reading">0. How to read this documentation</A></H1>
<P>If you are a first-time installer: be sure to read everything from here to
the end of the Installation section, and follow the links you will find. If
you have any other questions, return to the Table of Contents and
search for the topic, read the <A HREF="faq.html">FAQ</A>, or try grepping
through the files.</P>
<P>The main rule of this documentation: if it's not documented, it
<U>does not exist</U>. If I don't say you encode audio from TV tuner, you
can't. A healthy quantity of combining ability is welcomed, though.
Good luck. You'll need it :) And for another good advice, let me quote
Chris Phillips from the
<A HREF="http://mplayerhq.hu/pipermail/mplayer-users/">mplayer-users</A>
mailing list:</P>
<BLOCKQUOTE>
I said a while ago that there is such a difference between a newbie and
a dumbass. No matter what you actually know about a system (linux, cars,
girls :D) you should ALWAYS be able to take a step back and be objective,
otherwise, you're just dumb IMHO. A girl i live with assumed the vacuum
cleaner was broken because it didn't suck things up. never thought to change
the bag, becasue she'd never done it before... now that's just stupid, not a
case of simply not knowing what to do... Simply not being that familiar with
your surroundings is no excuse for a) laziness and b) ignorance. So many
people seem to see the word "error" and then stop... few seem to actually
read the words on the OTHER side of the colon.

<H1><A NAME="introduction">1. Introduction</A></H1>
<P><B>MPlayer</B> is a movie player for LINUX (runs on many other Unices, and
<B>non-x86</B> CPUs, see the <A HREF="#ports">ports section</A>). It plays most
MPEG, VOB, AVI, OGG, VIVO, ASF/WMV, QT/MOV, FLI, RM, NuppelVideo, yuv4mpeg,
FILM, RoQ, PVA files, supported by many native, XAnim, RealPlayer, and
Win32 DLL codecs. You can watch <B>VideoCD</B>, <B>SVCD</B>, <B>DVD</B>,
<B>3ivx</B>, <B>RealMedia</B>, and <B>DivX</B> movies too (and you don't need
the avifile
library at all!). Another big feature of <B>MPlayer</B> is the wide range of
supported output drivers. It works with X11, Xv, DGA, OpenGL, SVGAlib, fbdev,
AAlib, DirectFB, but you can also use GGI and SDL (and this way all their
drivers) and some lowlevel card-specific drivers (for Matrox, 3Dfx and Radeon,
Mach64, Permedia3) too! Most
of them supports software or hardware scaling, so you can enjoy movies in
fullscreen. <B>MPlayer</B> supports displaying through some hardware MPEG
decoder boards, such as the <B><A HREF="video.html#dvb">DVB</A></B> and
<B><A HREF="video.html#dxr3">DXR3/Hollywood+</A></B>. And what about the nice big antialiased
shaded subtitles (<B>10 supported types</B>) with European/ISO 8859-1,2
(Hungarian, English, Czech, etc), Cyrillic, Korean fonts, and the onscreen
display (OSD)?</P>
<P><B>MPlayer</B> is under GPL v2 license.</P>
<P>The player is rock solid playing damaged MPEG files (useful for some VCDs),
and it plays bad AVI files which are unplayable with the famous
windows media player. Even AVI files without index chunk are playable, and
you can temporarily rebuild their indexes with the <CODE>-idx</CODE> option, or
permanently with <B>MEncoder</B>, thus enabling seeking!
As you see, stability and quality are the most important things,
but the speed is also amazing.</P>
<H2><A NAME="history">1.1 History</A></H2>
<P>This began a year ago...
I (A'rpi) have tried lots of players under linux (mtv,xmps,dvdview,livid/oms,videolan,
xine,xanim,avifile,xmmp) but they all have some problem. Mostly with special
files or with audio/video sync. Most of them is unable to play both MPEG1,
MPEG2 and AVI (DivX) files. Many players have image quality or speed problems
too. So I've decided to write/modify one...</P>
<UL>
<LI><B>mpg12play v0.1-v0.3:</B> Sep 22-25, 2000<BR>
The first try, hacked together in a half hour!
I've used libmpeg3 from www.heroinewarrior.com up to the version 0.3,
but there were image quality and speed problems with it.</LI>
<LI><B>mpg12play v0.5-v0.87:</B> Sep 28-Oct 20, 2000<BR>
Mpeg codec replaced with DVDview by Dirk Farin, it was a great stuff,
but it was slow and was written in C++ (I hate C++!!!)</LI>
<LI><B>mpg12play v0.9-v0.95pre5:</B> Oct 21-Nov 2, 2000<BR>
Mpeg codec was libmpeg2 (mpeg2dec) by Aaron Holtzman & Michel Lespinasse.
It's great, optimized very fast C code with perfect image quality and
100% MPEG standard conformance.</LI>
<LI><B>MPlayer v0.3-v0.9:</B> Nov 18-Dec 4, 2000<BR>
It was a pack of two programs: mpg12play v0.95pre6 and my new simple AVI
player 'avip' based on avifile's Win32 DLL loader.</LI>
<LI><B>MPlayer v0.10:</B> Jan 1, 2001<BR>
The MPEG and AVI player in a single binary!</LI>
<LI><B>MPlayer v0.11pre series:</B><BR>
Some new developers joined and from 0.11 the mplayer project is a team-work!
Added .ASF file support, and OpenDivX (see www.projectmayo.com) en/decoding.</LI>
<LI><B>MPlayer v0.17a "The IdegCounter"</B> Apr 27, 2001<BR>
The release version of the 0.11pre after 4 months of heavy development!
Try it, and be amazed! Thousands of new features added... and of course
old code was improved too, bugs removed etc.</LI>
<LI><B>MPlayer 0.18 "The BugCounter"</B> Jul 9, 2001<BR>
2 months since 0.17 and here's a new release.. Completed ASF support,
more subtitle formats, introduced libao (similar to libvo but to audio),
even more stable than ever, and so on. It's a MUST!</LI>
<LI><B>MPlayer 0.50 "The Faszom(C)ounter"</B> Oct 8, 2001<BR>
Hmm. Release again. Tons of new features, beta GUI version, bugs fixed,
new vo and ao drivers, ported to many systems, including opensource DivX
codecs and much more. Try it!</LI>
<LI><B>MPlayer 0.60 "The RTFMCounter"</B> Jan 3, 2002<BR>
MOV/VIVO/RM/FLI/NUV fileformats support, native CRAM, Cinepak, ADPCM codecs,

<P>In this chapter I'll try to guide you through the compiling and
configuring process of <B>MPlayer</B>. It's not easy, but it won't necessarily
be hard. If you experience a different behavior than what I explain, please
search through this documentation and you'll find your answers. If you
see links, please follow them and read carefully what they contain. It
will take some time, but it DOES worth it.</P>
<P>You need a fairly recent system. On Linux, 2.4.x kernels are recommended.</P>
<H4>Software requirements:</H4>
<UL>
<LI><B>binutils</B> - suggested version is <B>2.11.x</B> . This program is
responsible for generating MMX/3DNow!/etc instructions, thus very important.</LI>
<LI><B>gcc</B> - suggested versions are: <B>2.95.3</B>, <B>2.95.4</B> and <B>3.1</B>.
<B>NEVER</B> use 2.96 or 3.0.x! They generate faulty code for MPlayer.
If you decide to change gcc from 2.96, then don't decide in favor of 3.0.x
just because it's newer! Early releases of 3.0.x were even more buggy than
2.96. So downgrade to 2.95.x (downgrade libstdc++ too, other programs may
need it) or don't up/downgrade at all (but in this case, be prepared for
runtime problems). If you vote for 3.x.x, try to use the latest version,
early releases had various bugs, so be sure you use at least 3.1, it's
tested and working. For detailed information about gcc 2.96's bugs (that are
still NOT fixed, they have been WORKED AROUND in <B>MPlayer</B>!), see the
<A HREF="users_against_developers.html#gcc">gcc 2.96</A> section and the
<A HREF="faq.html">FAQ</A>.</LI>
<LI><B>XFree86</B> - suggested version is <B>always the newest (4.2.1)</B>.
Normally, everyone wants this, as starting with XFree86 4.0.2, it contains
the <A HREF="video.html#xv">XVideo</A> extension (somewhere referred to
as <B>Xv</B>) which is needed to enable the hardware YUV acceleration (fast
image display) on cards that support it.<BR>
Make sure its <B>development package</B> is installed, too, otherwise
it won't work.<BR>
For some video cards you don't need XFree86. See list below.</LI>
<LI><B>make</B> - suggested version is <B>always the newest</B> (at least 3.79.x). This
usually isn't important.</LI>
<LI><B>SDL</B> - it's not mandatory, but can help in some cases (bad audio,
video cards that lag strangely with the xv driver). Always use the newest
(beginning from 1.2.x).</LI>
<LI><B>libjpeg</B> - optional JPEG decoder, used by -mf and some QT MOV files.
Useful for both <B>MPlayer</B> and <B>MEncoder</B> if you plan to work with jpeg files.</LI>
<LI><B>libpng</B> - recommended and default (M)PNG decoder. Required for GUI.
Useful for both <B>MPlayer</B> and <B>MEncoder</B>.</LI>
<LI><B>lame</B> - recommended, needed for encoding MP3 audio with MEncoder,
suggested version is <B>always the newest</B> (at least 3.90).</LI>
<LI><B>libogg</B> - optional, needed for playing OGG file format.</LI>
<LI><B>libvorbis</B> - optional, needed for playing OGG Vorbis audio.</LI>

<H4>Codecs:</H4>
<UL>
<LI><B>libavcodec</B>: This codec package is capable of decoding
H263/MJPEG/RV10/DivX3/DivX4/DivX5/MP41/MP42/WMV1 encoded video streams, on

to /usr/lib/win32 <B>BEFORE</B> compiling <B>MPlayer</B>, otherwise no Win32
support will be compiled!<BR>
<B>Note:</B> the avifile project has a similar codecs package, but it differs
from ours. If you want to use all supported codecs, then install our package
(do not worry, avifile works with it without problems). Features:<BR>
<UL>
<LI>you need this if you want to play or encode for example movies recorded
with various hardware compressors, like tuner cards, digital cameras
(example: DV, ATI VCR, MJPEG)</LI>
<LI>needed if you want to play <B>WMV8 movies</B>. Not needed for old
ASF's with MP41 or MP42 video (though VoxWare audio is frequent for these
files - it's done by the Win32 codec), or WMV7.</LI>
</UL>
</LI>
<LI><B>DivX4/DivX5</B>: information about this codec is available in the
<A HREF="codecs.html#divx">DivX4/DivX5</A> section. You possibly don't want
this codec as <B>libavcodec</B> (see above) is much faster and has better
quality than this, for both decoding and encoding.<BR>
Features:

<LI>1 pass or 2 pass encoding with
<A HREF="encoding.html">MEncoder</A></LI>
<LI>can play old <B>DivX3</B> movies much faster than the Win32 DLL but

</UL>
</LI>
<LI>The <A HREF="codecs.html#xanim">XAnim codecs</A> are the best (full
screen, hardware YUV zoom) for decoding <B>3ivx</B> and Indeo 3/4/5 movies,
and some old formats. And they are multiplatform, so this is the only way to
play Indeo on non-x86 platforms (well, apart from using XAnim:). But for
example Cinepak movies are best played with <B>MPlayer</B>'s own Cinepak
decoder!</LI>
<LI>For <B>Ogg Vorbis</B> audio decoding you need to install
<CODE>libvorbis</CODE> properly. Use deb/rpm packages if available, or
compile from
<A HREF="http://ogg.org/ogg/vorbis/download/vorbis_nightly_cvs.tgz">source</A>
(this is a nightly updated tarball of Vorbis CVS).</LI>
<LI><B>MPlayer</B> can use the libraries of RealPlayer 8 or RealONE to play
files with <B>RealVideo 2.0 - 4.0</B> video, and Sipro/Cook audio. See
<A HREF="formats.html#real">RealMedia file format</A> section for
installation instructions and more information.</LI>
</UL>
<H4>Video Cards</H4>
<P>There are generally two kind of video cards. One kind (the newer cards) has
<B>hardware scaling and YUV acceleration</B> support, the other cards don't.</P>
<H4>YUV cards</H4>
<P>They can display and scale (zoom) the picture to any size that fits in
their memory, with <B>small CPU usage</B> (even when zooming), thus
fullscreen playing is nice and very fast.</P>
<UL>
<LI><B>Matrox G200/G400/G450/G550 cards</B>: although a
<A HREF="video.html#vidix">Vidix driver</A> is provided, it is recommended
to use the mga_vid kernel module instead, for it works much better.
Please see the <A HREF="video.html#mga_vid">mga_vid</A> section about its
installation and usage. It is important to do these steps <I>before</I>
compiling <B>MPlayer</B>, otherwise no mga_vid support will be built. Also
check out the <A HREF="video.html#tv-out_matrox">Matrox TV-out</A> section.

<LI><B>S3 cards</B>: the Savage and Virge/DX chips have hardware acceleration.
Use as new XFree86 version as possible, older drivers are buggy. Savage chips
have problems with YV12 display, see <A HREF="video.html#xv_s3">S3 Xv

support.</LI>
<LI><B>nVidia cards</B>: very bad choice for video playing (nVidia
<A HREF="users_against_developers.html#nvidia">does not think so</A>).
nVidia's cards have very cheap and bad quality chips. Moreover, <B>the
built-in nVidia driver in XFree86 does not support hardware YUV
acceleration on all nVidia cards.</B> You have to download nVidia's
closed-source drivers from nVidia.com. See the <A

<UL>
<LI>Try if the XFree86 driver (and your card) supports hardware
acceleration. See the <A HREF="video.html#xv">Xv section</A> for
details.</LI>
<LI>If it doesn't, then your card's video features aren't supported under
your operating system :(<BR>
If hardware scaling works under Windows, it doesn't mean it will work
under Linux or other operating systems: it depends on the drivers. Most
manufacturers neither make Linux drivers nor release specifications
for their chips, so you are unlucky using their cards.

<P>Fullscreen playing can be achieved by either enabling <B>software scaling</B>
(use the <CODE>-zoom</CODE> or <CODE>-vop scale</CODE>
option, but I warn you: this is slow), or switching to a small resolution
video mode, for example 352x288. If you don't have YUV acceleration, the
latter method is recommended. Video mode switching can be enabled by
using the <CODE>-vm</CODE> option and it works with the following drivers:</P>

<LI>XFree86 3: works in 8/16bpp modes. However, the driver is
dramatically slow and buggy in 800x600@16bpp.
<B>Recommended: 640x480@16bpp</B></LI>
<LI>XFree86 4: the Xserver freezes soon after start unless
acceleration is disabled, but then the whole thing gets
slower than XFree86 3. No XVideo.</LI>
<LI>FBdev: framebuffer can be turned on with the <CODE>clgenfb</CODE>
driver in the kernel, though for me it worked only in 8bpp, thus
unusable. The clgenfb source had to be extended with the 7548 ID
before compilation.</LI>
<LI>VESA: the card is only VBE 1.2 capable, so VESA output can't be
used. Can't be workarounded with UniVBE.</LI>

</UL>
<P>Then build <B>MPlayer</B>:</P>
<PRE>
./configure
make
make install
</PRE>
<P>At this point, <B>MPlayer</B> is ready to use. The directory
<CODE>$PREFIX/share/mplayer</CODE> contains the <CODE>codecs.conf</CODE>
file, which is used to tell the program all the codecs and their
capabilities. This file should always be kept up to date together with the
main binary.<BR>
Check if you have <CODE>codecs.conf</CODE> in your home directory
(<CODE>~/.mplayer/codecs.conf</CODE>) left from old <B>MPlayer</B> versions, and remove it.</P>
<P><B>Debian users</B> can build a <CODE>.deb</CODE> package for themselves,
it's very simple. Just exec <CODE>fakeroot debian/rules binary</CODE> in
<B>MPlayer</B>'s root directory. See
<A HREF="documentation.html#debian">Debian packaging</A> for detailed
instructions.</P>
<P><B>Always browse the output of <CODE>./configure</CODE></B>, and the
<CODE>configure.log</CODE> file, they contain information about what will be
built, and what will not. You may also want to view <CODE>config.h</CODE> and
<CODE>config.mak</CODE> files.<BR>
If you have some libraries installed, but not detected by
<CODE>./configure</CODE>, then check if you also have the proper header files
(usually the -dev packages) and their version matches. The
<CODE>configure.log</CODE> file usually tells you what is missing.</P>
<P>Though not mandatory, the fonts should be installed in order to gain OSD,

</PRE>
<H2><A NAME="gui">1.3 What about the GUI?</A></H2>
<P>The GUI needs GTK (it isn't GTK, but the panels are). The skins are stored
in PNG format, so gtk, libpng (and their devel stuff) has to be installed.
You can build it by specifying <CODE>--enable-gui</CODE> during
<CODE>./configure</CODE>. Then, to turn on GUI mode, you either</P>
<UL>
<LI>specify <CODE>gui=yes</CODE> in your config file</LI>
<LI><CODE>ln -s $PREFIX/bin/mplayer $PREFIX/bin/gmplayer</CODE> ,
and call <CODE>gmplayer</CODE> instead.</LI>
</UL>
<P>Currently you can't use the <CODE>-gui</CODE> option on the command line,
due to technical reasons.</P>
<P>As <B>MPlayer</B> doesn't have a skin included, you have to download them if
you want to use the GUI. See the
<A HREF="http://www.mplayerhq.hu/homepage/dload.html">download page</A>.
They should be extracted to the usual system-wide directory
(<CODE>$PREFIX/share/mplayer/Skin</CODE>), or to
<CODE>$HOME/.mplayer/Skin</CODE>. <B>MPlayer</B> by default looks in these
directories for a directory named <I>default</I>, but you can use the

<LI>MPsub</LI>
<LI>AQTitle</LI>
</UL>
The command line options differ slightly for the different formats:
<H4>VobSub subtitles</H4>
<P>VobSub subtitles consist of a big (some megabytes) .SUB file, and optional
.IDX and/or .IFO files.<BR>
Usage: if you have files like <CODE>sample.sub</CODE>,
<CODE>sample.ifo</CODE>, <CODE>sample.idx</CODE> - you have to pass the
<CODE>-vobsub sample -vobsubid
<id></CODE> options (optionally with pathname, of course). The
<CODE>-vobsubid</CODE> option is like <CODE>-sid</CODE> for DVDs, you can
choose between subtitle tracks (languages) with it.</P>
<H4>Other subtitles</H4>
<P>The other formats consist of a single text file containing timing,
placement and text information.<BR>
Usage: if you have a file like <CODE>sample.txt</CODE>, you have to pass the
option <CODE>-sub sample.txt</CODE> (optionally with pathname, of course).</P>
<H4>Adjusting subtitle timing and placement:</H4>
<DL>
<DT><CODE>-subdelay <sec></CODE></DT>
<DD>Delays subtitles by <sec> seconds. Can be negative.</DD>
<DT><CODE>-subfps <rate></CODE></DT>
<DD>Specify frame/sec rate of subtitle file (float number)</DD>
<DT><CODE>-subpos <0 - 100></CODE></DT>
<DD>Specify the position of subtitles.</DD>
</DL>
<P>If you experience a growing delay between the movie and the subtitles when
using a MicroDVD subtitle file, most likely the frame rate of the movie and
the subtitle file are different.<BR> Please note that the MicroDVD subtitle
format uses absolute frame numbers for its timing, and therefore the
<CODE>-subfps</CODE> option cannot be used with this format. As
<B>MPlayer</B> has no way to guess the frame rate of the subtitle file, you
have to manually convert the frame rate. There is a little perl script in the
<CODE>contrib</CODE> directory of the MPlayer FTP site to do this conversion
for you.</P>
<P>About DVD subtitles, read the <A HREF="cd-dvd.html#dvd">DVD section</A>.</P>
<H3><A NAME="mpsub">1.4.1 MPlayer's own subtitle format (MPsub)</A></H3>
<P><B>MPlayer</B> introduces a new subtitle format called <B>MPsub</B>. It was
designed by me (Gabucino). Basically its main feature is being
<I>dynamically</I> time-based (although it has frame-based mode too). Example
(from
<A HREF="tech/mpsub.sub">DOCS/tech/mpsub.sub</A>):</P>
<P><CODE><I># first number : wait this much after previous subtitle disappeared<BR>
# second number : display the current subtitle for this many seconds<BR>
<BR>
15 3<BR>
A long long, time ago...<BR>
<BR>
0 3<BR>
in a galaxy far away...<BR>
<BR>
0 3<BR>
Naboo was under an attack.<BR></I></CODE></P>
<P>So you see, the main goal was to <B>make subtitle
editing/timing/joining/cutting easy</B>. And, if you - say - get an SSA
subtitle but it's badly timed/delayed to your version of the movie, you
simply do a <CODE>mplayer dummy.avi -sub source.ssa -dumpmpsub</CODE>.
A <CODE>dump.mpsub</CODE> file will be created in the current directory,
which will contain the source subtitle's text, but in <B>MPsub</B> format.
Then you can freely add/subtract seconds to/from the subtitle.</P>
<P>Subtitles are displayed with a technique called <B>'OSD', On Screen
Display</B>. OSD is used to display current time, volume bar, seek bar

<P>You need an <B>MPlayer</B> font package to be able to use OSD/SUB feature.
There are many ways to get it:</P>
<UL>
<LI>download ready-to-use font packages from <B>MPlayer</B> site.
Note: currently available fonts are limited for iso 8859-1/2 support,
but there are some other (including Korean, Russian, 8859-8 etc) fonts
at contrib/font section of FTP, made by users.<BR>
<BR>
Font should have appropriate font.desc file which maps unicode font
positions to the actual code page of the subtitles text. Other solution is
to have subtitles encoded in utf8 encoding and use <CODE>-utf8</CODE>
option or just name the subtitles file <video_name>.utf and have it
in the same dir as the video file. Recoding from different codepages to
utf8 could be done by using konwert (Debian) or iconv (Red Hat)
programs.<BR>

</UL>
</LI>
<LI>use the font generator tool at TOOLS/subfont-c
It's a complete tool to convert from TTF/Type1/etc font to mplayer font pkg.
(read TOOLS/subfont-c/README for details)</LI>
<LI>use the font generator GIMP plugin at TOOLS/subfont-GIMP
(note: you must have HSI RAW plugin too, see URL below)</LI>
</UL>
<P>After that, UNZIP the file you downloaded to <CODE>~/.mplayer</CODE> or
<CODE>$PREFIX/share/mplayer</CODE>. Then rename or symlink one of them to
<CODE>font</CODE> (like: <CODE>ln -s ~/.mplayer/arial-24
~/.mplayer/font</CODE>). Now you have to see a timer at the upper left corner
of the movie (switch it off with the "o" key).</P>
<P>OSD has 3 states: (switch with 'o')</P>
<UL>
<LI>timer + volume bar + seek bar + subtitles</LI>
<LI>volume bar + seek bar + subtitles (default)</LI>
<LI>subtitles only</LI>
</UL>
<P>You can change default behaviour by setting <CODE>osdlevel=</CODE> variable
in config file.</P>
<H2><A NAME="rtc">1.5 RTC</A></H2>
There are three timing methods in <B>MPlayer</B>.
<UL>
<LI><B>To use the old method</B>, you don't have to do anything. It uses
<CODE>usleep()</CODE> to tune A/V sync, with +/- 10ms accuracy. However
sometimes the sync has to be tuned even finer.</LI>
<LI><B>The new timer</B> code uses PC's RTC (Real Time Clock) for this task,
because it has precise 1ms timers. It is automagically enabled when
available, but requires root privileges, a <I>setuid root</I>
<B>MPlayer</B> binary or a properly set up kernel.
<BR>
If you are running kernel 2.4.19pre8 or later you can adjust the maximum
RTC frequency for normal users through the <CODE>/proc</CODE> filesystem.
Use this command to enable RTC for normal users:
<P>
<CODE>echo 1024 > /proc/sys/dev/rtc/max-user-freq</CODE>
</P>
If you do not have such a new kernel, you can also change one line in
<CODE>drivers/char/rtc.c</CODE> and recompile your kernel. Find the
section that reads
<PRE>
* We don't really want Joe User enabling more
* than 64Hz of interrupts on a multi-user machine.
*/
if ((rtc_freq > 64) && (!capable(CAP_SYS_RESOURCE)))
</PRE>
and change the 64 to 1024. You should really know what you are doing, though.
<BR>
You can see the new timer's efficiency in the status line.
<BR>
The power management functions of some notebook BIOSes with speedstep CPUs
interact badly with RTC. Audio and video may get out of sync. Plugging the
external power connector in before you power up your notebook seems to help.
You can always turn off RTC support with the <CODE>-nortc</CODE> switch.
In some hardware combinations (confirmed during usage of non-DMA DVD
drive on an ALi1541 board) usage of the RTC timer causes skippy playback.
It's recommended to use the third method in these cases.</LI>
<LI><B>The third timer code</B> is turned on with the <CODE>-softsleep</CODE>
option. It has the efficiency of the RTC, but it doesn't use RTC. On the other
hand, it requires more CPU.</LI>
</UL>
<B>Note:</B> <B>NEVER install a setuid root MPlayer binary on a multiuser system!</B>
It's a clear way for everyone to become root.

<P>If you have installed the lirc-package, configure will autodetect it. If
everything went fine, <B>MPlayer</B> will print a message like "Setting up

doesn't tell you anything about LIRC there's no support compiled in. That's
it :-)</P>
<P>The application name for <B>MPlayer</B> is - oh wonder - 'mplayer'.
You can use any mplayer commands and even pass more than one command by
separating them with \n. Don't forget to enable the repeat flag in .lircrc

<P>If <B>MPlayer</B> complains about not finding '/dev/cdrom' or
'/dev/dvd' make a symbolic link, e.g. <CODE>ln -s
/dev/rcd0c /dev/dvd</CODE></P>
<P>The not so hardcore hackers amongst us might want to use the ports
version (/usr/ports/x11/mplayer).</P>
<H2><A NAME="cygwin">6.8. Cygwin</A></H2>
<P>You will have to go to the <B>MPlayer</B> directory, and copy or symlink
<CODE>etc/cygwin_inttypes.h</CODE> to <CODE>/usr/include/inttypes.h</CODE> to
make <B>MPlayer</B> compile. Otherwise it will complain about missing
<CODE>intypes.h</CODE>.</P>

<H1><A NAME="known_bugs">Appendix C - Known bugs</A></H1>
<P>Special system/CPU-specific bugs/problems:</P>
<UL>
<LI>SIGILL (signal 4) on P3 using 2.2.x kernels:<BR>
Problem: kernel 2.2.x doesn't have proper (working) SSE support<BR>
Solution: upgrade kernel to 2.4.x<BR>
Workaround: <CODE>./configure --disable-sse</CODE></LI>
<LI>General SIGILL (signal 4):<BR>
Problem: you compiled and run mplayer in different machines
(for example compiled on P3 and running on Celeron)<BR>
Solution: compile MPlayer on the same machine where you will use it!<BR>
Workaround: <CODE>./configure --disable-sse</CODE> etc. options</LI>
<LI>"Internal buffer inconsistency" during MEncoder run:<BR>
Problem: known problem when lame < 3.90 was compiled with gcc 2.96 or 3.x.<BR>
Solution: use lame >=3.90.<BR>
Workaround: compile lame with gcc 2.95.x and remove any already installed
lame packages, they may have been compiled with gcc 2.96.</LI>
<LI>Messed up MP2/MP3 sound on PPC:<BR>
Problem: known GCC miscompilation bug on PPC platforms, no fix yet.<BR>
Workaround: use FFmpeg's (slow) MP1/MP2/MP3 decoder (<CODE>-ac ffmpeg</CODE>)</LI>
<LI>sig11 in libmpeg2, when scaling+encoding:<BR>
Problem: known GCC 2.95.2 MMX bug, upgrade to 2.95.3.</LI>
</UL>
<P>Various A-V sync and other audio problems:</P>
General audio delay or jerky sound (exists with all or many files):
<UL>
<LI>most common: buggy audio driver! - try to use different drivers, try
ALSA 0.9 OSS emulation with -ao oss, also try -ao sdl, sometimes it helps.
If your file plays fine with -nosound, then you can be sure it's sound card
(driver) problem.</LI>
<LI>audio buffer problems (buffer size badly detected)<BR>
Workaround: mplayer -abs option</LI>
<LI>samplerate problems - maybe your card doesn't support the samplerate
used in your files - try the resampling plugin (-aop)</LI>
<LI>slow machine (CPU or VGA)<BR>
try with -vo null, if it plays well, then you have slow VGA card/driver<BR>
Workaround: buy a faster card or read this documentation about how to speed up<BR>
Also try -framedrop</LI>
</UL>
Audio delay/de-sync specific to one or a few files:
<UL>
<LI>bad file<BR>
Workaround:
<UL>
<LI>-ni or -nobps option (for non-interleaved or bad files)<BR>
and/or</LI>
<LI>-mc 0 (required for files with badly interleaved VBR audio)<BR>
and/or</LI>
<LI>-delay option or +/- keys at runtime to adjust delay</LI>
</UL>
If none of these help, please upload the file, we'll check (and fix).
</LI>
<LI>your sound card doesn't support 48kHz playback<BR>
Workaround: buy a better sound card... or try to decrease fps by 10% (use
-fps 27 for a 30fps movie) or use the resampler plugin</LI>
<LI>slow machine<BR>
(if A-V is not around 0, and the last number in the status line increasing)<BR>
Workaround: -framedrop</LI>
</UL>
No sound at all:
<UL>
<LI>your file uses an unsupported audio codec<BR>
Workaround: read the documentation and help us adding support for it</LI>
</UL>
No picture at all (just plain grey/green window):
<UL>
<LI>your file uses an unsupported video codec<BR>
Workaround: read the documentation and help us adding support for it</LI>
<LI>auto-selected codec can't decode the file, try to select another using -vc
or -vfm options</LI>
<LI>you try to play DivX 3.x file with OpenDivX decoder or XviD (-vc odivx)
- install Divx4Linux and recompile player</LI>
</UL>
<P>Video-out problems:</P>
<P>First note: options -fs -vm and -zoom are just recommendations, not (yet)
supported by all drivers. So it isn't a bug if it doesn't work.
Only a few driver supports scaling/zooming, don't expect this from x11 or dga.</P>
<P>OSD/sub flickering:<BR>
- x11 driver: sorry, it can't be fixed now<BR>
- xv driver: use -double option</P>
<P>Green image using mga_vid (-vo mga / -vo xmga):<BR>
- mga_vid misdetected your card's RAM amount, reload it using mga_ram_size option</P>
