<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.
</BLOCKQUOTE>
<H1><A NAME="introduction">1. Introduction</A></H1>
<P>MPlayer 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 MPlayer 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. MPlayer 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>MPlayer 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 MEncoder, 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 &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,
and support for XAnim's binary codecs; DVD subtitles support, first
release of MEncoder, TV grabbing, cache, liba52, countless fixes.</LI>

<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 MPlayer. 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 MPlayer!), see the
<A HREF="users_against_developers.html#gcc">gcc 2.96</A> section and the
<A HREF="faq.html">FAQ</A>.</LI>

</UL>
<P>Then build MPlayer:</P>
<PRE>
./configure
make
make install
</PRE>
<P>At this point, MPlayer 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 MPlayer 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
MPlayer'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
<A HREF="#subtitles_osd">Subtitles and OSD</A> section for details.</P>
<PRE>
mkdir ~/.mplayer
cd ~/.mplayer
unzip mp-arial-iso-8859-1.zip
ln -s ~/.mplayer/iso-8859-1/arial-24 font
</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 $PREFIX/bin/gmplayer</CODE> ,
and call <CODE>gmplayer</CODE> instead.</LI>
</UL>
<P>Currently you can't use the <CODE>-gui</CODE> option on the command line,
due to technical reasons.</P>
<P>As MPlayer doesn't have a skin included, you have to download them if
you want to use the GUI. See the
<A HREF="http://www.mplayerhq.hu/homepage/dload.html">download page</A>.
They should be extracted to the usual system-wide directory
(<CODE>$PREFIX/share/mplayer/Skin</CODE>), or to
<CODE>$HOME/.mplayer/Skin</CODE>. MPlayer by default looks in these
directories for a directory named <I>default</I>, but you can use the
<CODE>-skin newskin</CODE> option, or the <CODE>skin=newskin</CODE> config
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>
MPlayer 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
MPlayer 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>MPlayer 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 MPlayer 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 MPlayer 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>

<CODE>font</CODE> (like: <CODE>ln -s ~/.mplayer/arial-24

<H2><A NAME="rtc">1.5 RTC</A></H2>
There are three timing methods in MPlayer.
<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>
MPlayer 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>

<LI>If you capture the video with the vertical resolution higher than half of
the full resolution (i.e. 288 for PAL or 240 for NTSC), make sure you
turned deinterlacing on. Otherwise you'll get a movie which is distorted
during fast-motion scenes and the bitrate controller will be probably even
unable to retain the specified bitrate as the interlacing artifacts produce
high amount of detail and thus consume lot of bandwidth. You can enable
deinterlacing with <CODE>-vop pp=DEINT_TYPE</CODE>. Usually
<CODE>pp=lb</CODE> does a good job, but it can be matter of personal
preference. See other deinterlacing algorithms in the manual and give it a
try.</LI>
<LI>Crop out the dead space. When you capture the video, the areas at the
edges are usually black or contain some noise. These again consume lots of
unnecessary bandwidth. More precisely it's not the black areas themselves
but the sharp transitions between the black and the brighter video image
which do but that's not important for now. Before you start capturing,
adjust the arguments of the <CODE>crop</CODE> option so that all the crap
at the margins is cropped out. Again, don't forget to keep the resulting
dimensions sane.</LI>
<LI>Watch out for CPU load. It shouldn't cross the 90% boundary for most of
the time. If you have a large capture buffer, MEncoder can survive an
overload for few seconds but nothing more. It's better to turn off the 3D
OpenGL screensavers and similar stuff.</LI>
<LI>Don't mess with the system clock. MEncoder uses the system clock for
doing A/V sync. If you adjust the system clock (especially backwards in
time), MEncoder gets confused and you will lose frames. This is an
important issue if you are hooked to a network and run some time
synchronization software like NTP. You have to turn NTP off during the
capture process if you want to capture reliably.</LI>
<LI>Don't change the <CODE>outfmt</CODE> unless you know what you are doing
or your card/driver really doesn't support the default (YV12 colorspace).
In the older versions of MPlayer/MEncoder it was necessary to specify the
output format. This issue should be fixed in the current releases and
<CODE>outfmt</CODE> isn't required anymore, and the default suits the most
purposes. For example, if you are capturing into DivX using libavcodec and
specify <CODE>outfmt=RGB24</CODE> in order to increase the quality of the
captured images, the captured image will be actually later converted back
into YV12 so the only thing you achieve is a massive waste of CPU power.
</LI>
<LI>To specify the I420 colorspace (<CODE>outfmt=i420</CODE>), you have to
add an option <CODE>-vc rawi420</CODE> due to a fourcc conflict with an
Intel Indeo video codec.</LI>
<LI>There are several ways of capturing audio. You can grab the sound either
using your soundcard via an external cable connection between video card
and line-in, or using the built-in ADC in the bt878 chip. In the latter
case, you have to load the <b>btaudio</b> driver. Read the
<CODE>linux/Documentation/sound/btaudio</CODE> file (in the kernel tree,
not MPlayer's) for some instructions on using this driver.</LI>
<LI>If MEncoder cannot open the audio device, make sure that it is really
available. There can be some trouble with the sound servers like arts
(KDE) or esd (GNOME). If you have a full duplex soundcard (almost any
decent card supports it today), and you are using KDE, try to check the
"full duplex" option in the sound server preference menu.</LI>

Input from standard V4L<BR>
<CODE>&nbsp;&nbsp;&nbsp;&nbsp;mplayer -tv
on:driver=v4l:width=640:height=480 -vo xv</CODE><BR>
<BR>
A more sophisticated example. This makes MEncoder capture the full
PAL image, crop the margins, and deinterlace the picture using
a linear blend algorithm. Audio is compressed with a constant
bitrate of 64kbps, using LAME codec. This setup is suitable for
capturing movies.<BR> <CODE> &nbsp;&nbsp;&nbsp;&nbsp;mencoder -tv
on:driver=v4l:width=768:height=576 \<BR>
&nbsp;&nbsp;&nbsp;&nbsp;-ovc lavc -lavcopts
vcodec=mpeg4:vbitrate=900 \<BR> &nbsp;&nbsp;&nbsp;&nbsp;-oac
mp3lame -lameopts cbr:br=64 \<BR> &nbsp;&nbsp;&nbsp;&nbsp;-vop
pp=lb,crop=720:540:24:18 -o output.avi </CODE><BR>
<BR>
This will additionally rescale the image to 384x288 and compresses
the video with the bitrate of 350kbps in high quality mode. The
vqmax option looses the quantizer and allows the video compressor to
actualy reach so low bitrate even at the expense of the
quality. This can be used for capturing long TV series, where the
video quality isn't so important.<BR>
<CODE>
&nbsp;&nbsp;&nbsp;&nbsp;mencoder -tv on:driver=v4l:width=768:height=576 \<BR>
&nbsp;&nbsp;&nbsp;&nbsp;-ovc lavc -lavcopts vcodec=mpeg4:vbitrate=350:vhq:vqmax=31:keyint=300 \<BR>

&nbsp;&nbsp;&nbsp;&nbsp;-vop scale=384:288,pp=tn/lb,crop=720:540:24:18 -sws 1 -o output.avi
</CODE><BR>
It's also possible to specify smaller image dimensions in the
<CODE>-tv</CODE> option and omit the software scaling but this
approach uses the maximum available information and is a little more
resistant to noise. The bt8x8 chips can do the pixel averaging only
in the horizontal direction due to a hardware limitation.</P>

<P>Linux Infrared Remote Control - use an easy to build home-brewn IR-receiver,
an (almost) arbitrary remote control and control your Linux box with it!
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, MPlayer will print a message like "Setting up
lirc support..." on startup. If an error occurs it will tell you. If it
doesn't tell you anything about LIRC there's no support compiled in. That's
it :-)</P>
<P>The application name for MPlayer is - oh wonder - <CODE>mplayer</CODE>.
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
when it make sense (seek, volume, etc). Here's an excerpt from my
.lircrc:</P>
<PRE>
begin
button = VOLUME_PLUS
prog = mplayer
config = volume 1
repeat = 1
end
begin
button = VOLUME_MINUS
prog = mplayer
config = volume -1
repeat = 1
end
begin
button = CD_PLAY
prog = mplayer
config = pause
end
begin
button = CD_STOP
prog = mplayer
config = seek 0 1\npause

use the -lircconf &lt;filename&gt; switch to specify another file.</P>
<H3><A NAME="slave">3.2.3 Slave mode</A></H3>
<P>The slave mode allow you to build simple frontend to MPlayer. When
enabled (with the <CODE>-slave</CODE> switch) MPlayer 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>MPlayer can play files from network, using the HTTP, MMS or RTSP/RTP
protocol.</P>
<P>Playing goes by simply using adding the URL to the command line.
MPlayer 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>MPlayer 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>

<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 &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>
- 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>
