<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 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 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,

  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>

  <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 &amp; 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,

<H2><A NAME="installation">1.2 Installation</A></H2>

<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 (4.2.0)</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>

<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,
  and subtitle functionality. Download <CODE>mp-arial-iso-8859-*.zip</CODE>
  and/or optional (if exists) language updates. See the

<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>use the <CODE>-gui</CODE> option</LI>

<BLOCKQUOTE>
  <B>Hint</B><BR>
  Press the middle button (on 2 button mice press left and right
  simultaneously) to open a GTK menu with a DVD playing option.
</BLOCKQUOTE>

<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

  file directive to use the skin in <CODE>*/Skin/newskin</CODE> directory.</P>


<H2><A NAME="subtitles_osd">1.4 Subtitles and OSD</A></H2>

<P>
  <B>MPlayer</B> can display subtitles along with movie files. Currently the following 
  formats are supported:</P>
<UL>
  <LI>VobSub</LI>
  <LI>Microdvd</LI>
  <LI>SubRip</LI>
  <LI>SubViewer</LI>
  <LI>Sami</LI>
  <LI>VPlayer</LI>
  <LI>RT</LI>
  <LI>SSA</LI>
  <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
  &lt;id&gt;</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 &lt;sec&gt;</CODE></DT>
  <DD>Delays subtitles by &lt;sec&gt; seconds. Can be negative.</DD>

  <DT><CODE>-subfps &lt;rate&gt;</CODE></DT>
  <DD>Specify frame/sec rate of subtitle file (float number)</DD>

  <DT><CODE>-subpos &lt;0 - 100&gt;</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

<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
  etc.</P>

<H3><A NAME="install_osd">1.4.2 Installing OSD and subtitles</A></H3>

<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 &lt;video_name&gt;.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>
    Some URLs:
    <UL>
      <LI><A HREF="ftp://ftp.mplayerhq.hu/MPlayer/releases/">ftp://ftp.mplayerhq.hu/MPlayer/releases/</A> - ISO fonts</LI>
      <LI><A HREF="ftp://ftp.mplayerhq.hu/MPlayer/contrib/fonts/">ftp://ftp.mplayerhq.hu/MPlayer/contrib/fonts/</A> - various fonts by users</LI>
      <LI><A HREF="http://realtime.ssu.ac.kr/~lethean/mplayer">http://realtime.ssu.ac.kr/~lethean/mplayer</A> - Korean fonts &amp; RAW plugin</LI>
    </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 &gt; /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 &gt; 64) &amp;&amp; (!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.

  More about it at <A HREF="http://www.lirc.org">www.lirc.org</A>.</P>

<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

<P>If you don't like the standard location for the lirc-config file (~/.lircrc)
  use the -lircconf &lt;filename&gt; switch to specify another file.</P>


<H3><A NAME="slave">3.2.4 Slave mode</A></H3>

<P>The slave mode allow you to build simple frontend to <B>MPlayer</B>. When
  enabled (with the <CODE>-slave</CODE> switch) <B>MPlayer</B> will read
  commands separated by new line (\n) from stdin.</P>


<H2><A NAME="streaming">3.3 Streaming from network or pipes</A></H2>

<P><B>MPlayer</B> can play files from network, using the HTTP or MMS protocol.</P>

<P>Playing goes by simply using adding the URL to the command line.
  <B>MPlayer</B> also honors the http_proxy environment variable, and uses
  proxy if available. Proxy usage can also be forced:</P>

<P><CODE>mplayer http_proxy://proxy.micorsops.com:3128/http://micorsops.com:80/stream.asf</CODE></P>

<P><B>MPlayer</B> can read from stdin (NOT named pipes). This can be for example
  used to play from FTP:</P>

<P><CODE>&nbsp;&nbsp;wget ftp://micorsops.com/something.avi -O - | mplayer -</CODE></P>

<P>Note: it's also recommended to enable CACHE when playback from network:</P>

<P><CODE>&nbsp;&nbsp;wget ftp://micorsops.com/something.avi -O - | mplayer -cache 8192 -</CODE></P>

<H2><A NAME="debian">6.1 Debian packaging</A></H2>

<P>To build the package, get the cvs version, or .tgz and uncompress it,
  and cd into programs directory:</P>

<PRE>
    cd main
    fakeroot debian/rules binary
</PRE>

<P>(... mplayer detects hardware/software, builds itself and.. )
  dpkg-deb: building package `mplayer' in `../mplayer_0.90-1_i386.deb'.</P>

<P>And now just become root, and:</P>

<PRE>
    dpkg -i ../mplayer_0.90-1_i386.deb as root.
</PRE>

<P>Here's how it looks like:</P>

<PRE>
	eyck@incubus:/src/main$ sudo dpkg -i ../mplayer_0.90-1_i386.deb
	Password:
	(Reading database ... 26946 files and directories currently installed.)

	Unpacking replacement mplayer ...
	Setting up mplayer (0.90-1) ...
</PRE>


<H2><A NAME="freebsd">6.2 FreeBSD</A></H2>

<P>To build the package you will need GNU make (gmake, /usr/ports/devel/gmake),
  native BSD make will not work.</P>

<P>To run <B>MPlayer</B> you will need to re-compile the kernel with
  "options USER_LDT" (unless you are running -CURRENT, where this is default).
  If you have a CPU with SSE also use "options CPU_ENABLE_SSE" to use it
  (FreeBSD-STABLE required, or use kernel patches).</P>

<P>If <B>MPlayer</B> complains about "CD-ROM Device '/dev/cdrom' not found!" make a
  symbolic link: <CODE>ln -s /dev/(your_cdrom_device) /dev/cdrom</CODE></P>

<P>There's no DVD support for FreeBSD yet.</P>


<H2><A NAME="solaris">6.3 Solaris</A></H2>

<P>MPlayer should work on Solaris 2.6 or newer.</P>

<P>AVI file playback works best on Solaris x86, because you have the
  option to use the win32 codecs on the x86 platform, or can use
  MMX/MMX2/3DNow/etc instructions for MP3/DivX/DVD/whatever. On Colaris SPARC,
  you'll find quite a few AVI files with non working video and/or audio
  playback, because the video/audio codecs using the Win32 DLLs are not
  available. However, <B>DivX/OpenDivX</B> movies should work, when using
  libavcodec.</P>

<P>On <B>UltraSPARC</B>s, <B>MPlayer</B> takes advantage of their <B>VIS</B>
  extensions (equivalent to MMX), currently only in <I>libmpeg2</I>,
  <I>libvo</I> and <I>libavcodec</I>, but not in mp3lib. You can watch a VOB
  file on a 400MHz CPU. You'll need
  <A HREF="http://www.sun.com/sparc/vis/mediaLib.html">mLib</A> installed.</P>

<P>To build the package you will need GNU make (gmake, /opt/sfw/gmake), native
  Solaris make will not work. Typical error you get when building with Solaris'
  make instead of GNU make:</P>

<PRE>
   % /usr/ccs/bin/make
   make: Fatal error in reader: Makefile, line 25: Unexpected end of line seen
</PRE>

<P>On Solaris SPARC, you need the GNU C/C++ Compiler; it does not matter
  if GNU C/C++ compiler is configured with or without the GNU assembler.</P>

<P>On Solaris x86, you need the GNU assembler and the GNU C/C++ compiler,
  configured to use the GNU assembler! The mplayer code on the x86 platform
  makes heavy use of MMX, SSE and 3DNOW! instructions that cannot be compiled
  using Sun's assembler <CODE>/usr/ccs/bin/as</CODE>.</P>

<P>The configure script tries to find out, which assembler program is used by
  your "gcc" command (in case the autodetection fails, use the
  <CODE>--as=/whereever/you/have/installed/gnu-as</CODE> option to tell the
  configure script where it can find GNU "as" on your system).</P>

<P>Error message from configure on a Solaris x86 system using GCC
  without GNU assembler:</P>

<PRE>
   % configure
   ...
   Checking assembler (/usr/ccs/bin/as) ... , failed
   Please upgrade(downgrade) binutils to 2.10.1...
</PRE>

<P>(Solution: Install and use a gcc configured with "--with-as=gas")</P>

<P>Typical error you get when building with a GNU C compiler that does
  not use GNU as:</P>

<PRE>
   % gmake
   ...
   gcc -c -Iloader -Ilibvo -O4 -march=i686 -mcpu=i686 -pipe -ffast-math
	-fomit-frame-pointer  -I/usr/local/include   -o mplayer.o mplayer.c
   Assembler: mplayer.c
   "(stdin)", line 3567 : Illegal mnemonic
   "(stdin)", line 3567 : Syntax error
   ... more "Illegal mnemonic" and "Syntax error" errors ...
</PRE>

<P>For DVD support you must have the patched libcss installed. Patch:
  <A HREF="http://www.tools.de/solaris/mplayer/">http://www.tools.de/solaris/mplayer/</A>.</P>

<P>Due to two bugs in Solaris 8 x86, you cannot reliably play DVD discs larger
  than 4 GB:</P>

<UL>
  <LI>The sd(7D) driver on Solaris 8 x86 driver has bug when accessing a disk
    block &gt;4GB on a device using a logical blocksize != DEV_BSIZE (i.e.  CD-ROM
    and DVD media).  Due to a 32Bit int overflow, a disk address modulo 4GB is
    accessed.
    (<A HREF="http://groups.yahoo.com/group/solarisonintel/message/22516">http://groups.yahoo.com/group/solarisonintel/message/22516</A>)
  </LI>
  <LI>A similar bug is present in the hsfs(7FS) filesystem code (aka
    ISO9660), hsfs currently does not support partitions/disks larger than 4GB, all data
    is accessed modulo 4GB.
    (<A HREF="http://groups.yahoo.com/group/solarisonintel/message/22592">http://groups.yahoo.com/group/solarisonintel/message/22592</A>)
  </LI>
</UL>

<P>On Solaris with an UltraSPARC CPU, you can get some extra speed by
  using the CPU's VIS instructions for certain time consuming operations.
  VIS acceleration can be used in MPlayer by calling functions in Sun's
  <A HREF="http://www.sun.com/sparc/vis/mediaLib.html">mediaLib</A>.</P>

<P>VIS accelerated operations from mediaLib are used for mpeg2 video
  decoding and for color space conversion in the video output drivers.</P>


<H2><A NAME="strongarm">6.4 StrongARM</A></H2>

<P><B>MPlayer</B> is reported to compile on StrongARM. Use the following command line:</P>

<PRE>
  ./configure --target=arm-linux --disable-css --with-x11libdir=/usr/arm/lib
	      --with-x11incdir=/usr/arm/lib --disable-gcc-checking
</PRE>


<H2><A NAME="sgi">6.5 Silicon Graphics / IRIX</A></H2>

<P>Reported working. You'll probably have to use the <I>SGI</I> ao driver.
  Anyone has closer info?</P>


<H2><A NAME="qnx">6.6 QNX</A></H2>

<P>Works. You'll need to download SDL for QNX, and install it. Then run
  <B>MPlayer</B> with <CODE>-vo sdl:photon</CODE> and <CODE>-ao sdl:nto</CODE>
  options, and it should be fast.</P>

<P>The <CODE>-vo x11</CODE> output will be even slower than on Linux, since
  QNX has only X <I>emulation</I> which is VERY slow. Use SDL.</P>


<H2><A NAME="openbsd">6.7 OpenBSD</A></H2> 
    
<P>To build the package you will need GNU make (gmake,
  /usr/ports/devel/gmake), native BSD make will not work, and a recent
  binutils (including objcopy).</P>

<P>Due to limitations in different versions of gas (relocation vs mmx), you'll
  need to compile in two steps: First make sure that the non-native as is first
  in PATH and do a '<CODE>gmake -k</CODE>', then make sure that the native
  version is used and do '<CODE>gmake</CODE>'.</P>

<P>To use Win32 DLLs with <B>MPlayer</B> you will need to re-compile the
  kernel with "<CODE>option USER_LDT</CODE>".</P>

<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="bug_reports">Appendix C</A> - <A HREF="bugreports.html">How to report bugs</A></H1>



<H1><A NAME="known_bugs">Appendix D - 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 &lt; 3.90 was compiled with gcc 2.96 or 3.x.<BR>
  Solution: use lame &gt;=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>
