1. Introduction

1.1. Overview

MPlayer is a movie player for LINUX (runs on many other Unices, and non-x86 CPUs, see section 6). It plays most MPEG, AVI and ASF files, supported by many native and Win32 DLL codecs. You can watch VideoCD, SVCD, DVD and even DivX movies too. The another big feature of mplayer is the wide range of supported output drivers. It works with X11, Xv, DGA, OpenGL, SVGAlib, fbdev, AAlib, but you can use SDL (and this way all drivers of SDL) and some lowlevel card-specific drivers (for Matrox) too! Most of them supports software or hardware scaling, so you can enjoy movies in fullscreen. And what about the nice big antialiased shaded subtitles (7 supported types!!!) with hungarian, english, cyrillic, czech, korean fonts, and OSD?

I didn't write any codecs, just some players. I spent a lot of time finding the best way to parse bad damaged input files (both MPEG and AVI) and to do perfect A-V sync with seeking ability. My 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 rebuild their indexes with the -idx option, thus enabling seeking! As you see, stability and quality are the most important things for me, but the speed is also amazing.

1.2. History

This began a year ago... I've 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...

mpg12play v0.1-v0.3:
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.
mpg12play v0.5-v0.87:
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++!!!)
mpg12play v0.9-v0.95pre5:
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.
MPlayer v0.3-v0.9:
It was a pack of two programs: mpg12playv0.95pre6 and my new simple AVI player 'avip' based on avifile's Win32 DLL loader.
MPlayer v0.10:
The MPEG and AVI player in a single binary!
MPlayer v0.11:
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.
MPlayer v0.17 "The IdegCounter"
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.
MPlayer 0.18 "The BugCounter"
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 !

1.3. Installation

You'll need the following packages and versions if you don't want to experience any problems:

binutils - suggested version is 2.11.x . This program is responsible for generating MMX/3DNow!/etc instructions, thus very important.
gcc - suggested version is from 2.95.2 to 2.95.4. NEVER use 2.96 or 3.x.x !!! They generate faulty code.
XFree86 - suggested version is always the newest (4.1.0). Normally everyone wants this. If you don't know why, you do need it.
make - suggested version is always the newest (at least 3.79.x). This usually isn't important.

Read the following before trying to compile MPlayer:

If you plan to use MPlayer on x86 architecture, you possibly want to use Win32 codecs. Download and unzip w32codecs.zip to /usr/lib/win32 . Note: the avifile project has similar codecs package, but it differs from ours, so if you want to use all supported codecs, then use our package! However, you can use our codecs package with avifile.
If you own a Matrox G200/G400/G450 card, then please see the 2.2.1.7 section in order to gain big speedup. It is important to do these steps before compiling MPlayer, otherwise no Matrox-specific support will be built.
If you plan to use the ProjectMayo's DivX4 codec, check the 2.1.2.1 section before compiling. This codec can play DivX movies much faster than the Win32 DLL, and ffmpeg. It's closed-source, and only an x86 version is available.
If you plan to use ffmpeg's libavcodec, check the 2.1.2.2 section before compiling. You'll need this to gain DivX playing on non-x86 machines, or want to gain bigger speed than the Win32 codec does.
For DVD support, you'll have to compile libdvdread and libcss. See section 4.2 for more information.

Then build MPlayer:

    ./configure
    make
    make install

It is recommended to browse the output of ./configure , it contains info about what will be built, and what won't. You may also want to view config.h and config.mak files.

Though not mandatory, the fonts should be installed in order to gain OSD, and subtitle functionality. Download mp_font3.zip and optional (if exists) language updates.

    mkdir ~/.mplayer/font
    cd ~/.mplayer/font
    unzip mp_font3.zip
    unzip mp_font3_hu.zip

Only one thing remains: copy the codecs.conf file from the etc directory (relative to the MPlayer tree) to $HOME/.mplayer/codecs.conf.

1.4. What about the GUI?

I'm not a GUI programmer. I hate GUIs, I like the pure black 80x25 console. So the player has only keyboard control from the controlling console/xterm now. There is a GUI development for the player, coordinated by Pontscho/Fresh! It's still under development, but it will be merged and released real soon. BTW he needs some nice skins, if you are a good graphician, contact him!!!

1.5. Subtitles and OSD

Yes, MPlayer also supports many kinds of subtitles. Currently 7 kinds of subtitle can be used by the subreader code. To see what are these subtitle formats, see subreader.c, line ~20.

Subtitles are displayed with a technique called 'OSD', On Screen Display. OSD is used to display current time, volume bar, seek bar etc.

INSTALLING OSD and SUB

You need an MPlayer font package to be able to use OSD/SUB feature. There are many ways to get it:

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)
use the font generator GIMP plugin at TOOLS/subfont-GIMP (note: you must have HSI RAW plugin too, see URL below)
download ready-to-use font packages from MPlayer site. Note: currently available fonts are limited for iso 8859-1/2 support, and there are a few special versions for korean, russian etc codepages. You better build fonts yourself with the tool mentioned above. 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 -utf8 option or just name the subtitles file
.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 (RedHat) programs.
Some URLs:
- ftp://ftp.mplayerhq.hu/MPlayer/releases/ - ISO fonts, OBSOLETED!
- ftp://ftp.mplayerhq.hu/MPlayer/contrib/fonts/ - various fonts by users
- http://realtime.ssu.ac.kr/~lethean/mplayer - korean fonts & RAW plugin

After that, UNZIP the files to ~/.mplayer/font/ . Now you have to see a timer at the upper left corner of the movie (switch it off with 'o') .

OSD has 3 states: (switch with 'o')

timer + volume bar + seek bar + subtitles (default)
volume bar + seek bar + subtitles
subtitles only

You can change default behaviour by setting osdlevel= variable in config file.

  mplayer -dvd 1 /dev/dvd
  mplayer -abs 65536 -delay -0.4 -nobps ~/movies/test.avi

3.1. Control from keyboard

<- or -> seek backward/forward 10 seconds
up or down seek backward/forward 1 minute
pgup/pgdown seek backward/forward 10 minutes
p or SPACE pause movie (press any key)
q or ESC stop playing and quit program
+ or - adjust audio delay by +/- 0.1 second
/ or * decrease/increase volume
o toggle OSD: none / seek / seek+timer
m toggle using master/pcm volume
z or x adjust subtitle delay by +/- 0.1 second

(the following keys are valid only when using DirectShow DivX codec)
1 or 2 adjust contrast
3 or 4 adjust brightness
5 or 6 adjust hue
7 or 8 adjust saturation

3.2. Control from LIRC

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 www.lirc.org.

If you have installed the lirc-package, you can compile MPlayer with LIRC support using ./configure --enable-lirc

If everything went fine, MPlayer will print a message like LIRC init was successful. on startup. If an error occurs it will tell you. If it doens't tell you anything about LIRC there's no support compiled in. That's it :-)

The application name for MPlayer is - oh wonder - mplayer_lirc. It understands the following commands:

PAUSE pause playing. Any other keystroke will continue replay.
QUIT exit MPlayer
RWND 10 secs back
FRWND 60 secs back
FWD skip 10 secs
FFWD skip 60 secs
INCVOL increase volume one percent
DECVOL decrease volume one percent
MASTER use master mixer channel
PCM use pcm mixer channel

Don't forget to enable the repeat flag for RWND/FWD in .lircrc. Here's an excerpt from my .lircrc:

  begin
   remote = CU-SX070
   prog = mplayer_lirc
   button = Tape_Play
   repeat = 1
   config = FFWD
  end

  begin
   remote = CU-SX070
   prog = mplayer_lirc
   button = Tape_Stop
   config = QUIT
  end

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

3.3. Streaming from network or pipes

MPlayer can play media from network, by using the HTTP protocol, and even beta ASF streaming (FROM network) is available. Configuring it is simple, just recompile MPlayer with

./configure --enable-streaming

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

wget ftp://micorsops.com/something.avi -O - | mplayer -

5. CD/DVD section

6. Misc OS'es

6.1. Debian packaging

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

    cd main
    fakeroot debian/rules binary

(... mplayer detects hardware/software, builds itself and.. ) dpkg-deb: building package `mplayer' in `../mplayer_0.18-1_i386.deb'.

And now just become root, and:

    dpkg -i ../mplayer_0.18-1_i386.deb as root.

Here's how it looks like:

	eyck@incubus:/src/main$ sudo dpkg -i ../mplayer_0.18-1_i386.deb 
	Password:
	(Reading database ... 26946 files and directories currently installed.)
	Preparing to replace mplayer 0.17a-1 (using ../mplayer_0.18-1_i386.deb)
	Unpacking replacement mplayer ...
	Setting up mplayer (0.18-1) ...

6.2. FreeBSD

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

To run MPlayer 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).

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

There's no DVD support for FreeBSD yet. (??? libdvdread?)

6.3. Solaris

MPlayer should work on Solaris 2.6 or newer.

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 Solaris 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, DivX/OpenDivX movies should work, when using libavcodec.

On UltraSPARCs, MPlayer takes advantage of their VIS extensions (equivalent to MMX), currently only in libmpeg2, libvo and libavcodec, but not in mp3lib. You can watch a VOB file on a 400Mhz CPU. You'll need mLib installed.

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:

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

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.

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 /usr/ccs/bin/as.

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

Error message from configure on a Solaris x86 system using GCC without GNU assembler:

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

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

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

   % 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 ...

For DVD support you must have the patched libcss installed. Patch: http://www.tools.de/solaris/mplayer/.

Due to two bugs in solaris 8 x86, you cannot reliably play DVDs using a capacity >4GB:

The sd(7D) driver on solaris 8 x86 driver has bug when accessing a disk block >4GB on a device using a logical blocksize != DEV_BSIZE (i.e. CDROM and DVD media). Due to a 32bit int overflow, a disk address modulo 4GB is accessed. (http://groups.yahoo.com/group/solarisonintel/message/22516)
The similar bug is present in the hsfs(7FS) filesystem code (aka ISO9660), hsfs currently does not support partitions/disks >4GB, all data is accessed modulo 4GB (http://groups.yahoo.com/group/solarisonintel/message/22592)

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 mediaLib.

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

6.4. StrongARM

MPlayer is reported to compile on StrongARM. Use the following command line:

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

SOLVED: disabled SSE code in fastmemcpy.h ;(
No image (black image) in RGB 15/16bpp (x11,dga,fbdev,svga) playing MPEG or OpenDivX files:
Problem: gcc 2.96 bug
Workaround: ./configure --disable-mmx, or use gcc 2.95.x
SOLVED: code fixed
SIGILL (signal 4) or other fault at loading l3codeca.acm:
Problem: shared libs are loaded to 0x00xxxxxx instead of 0x40xxxxxx
Workaround: mplayer -afm 1 ...
SOLVED: you are using some security kernel patch, like OpenWall etc.
SIGILL (signal 4) on P3 using 2.2.x kernels:
Problem: kernel 2.2.x doesn't have proper (working) SSE support
Solution: upgrade kernel to 2.4.x
Workaround: ./configure --disable-sse
General SIGILL (signal 4):
Problem: you compiled and run mplayer in different machines (for example compiled on P3 and running on celeron)
Solution: compile MPlayer on the same machine where you will use it!
Workaround: ./configure --disable-sse etc. options

Various A-V sync and other audio problems:

General audio delay or jerky sound (exists with all or many files):

audio buffer problems (buffer size badly detected)
Workaround: mplayer -abs option
slow machine (cpu or vga)
try with -vo null, if it plays well, then you have slow VGA card/driver
Workaround: buy a faster card or read this documentation about how to speed up
SOLVED: try -framedrop

Audio delay/de-sync specific to one or a few files:

bad file (please upload the file, so we can check & fix)
Workaround: -ni or -bps option (for non-interlaved or bad files)
-mc 0 (required for files with VBR audio)
-delay option or +/- keys at runtime to adjust delay
your soundcard doesn't support 48Khz playback
Workaround: buy a better soundcard... or try to decrease fps by 10% (use -fps 27 for a 30fps movie)
slow machine
(if A-V is not around 0, and the last number in the status line increasing)
Workaround: -framedrop

No sound at all:

your file uses an unsupported codec
Workaround: read the documentation and help us adding support for it

Video-out problems:

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.

OSD/sub flickering:
- x11 driver: sorry, it can't be fixed now
- xv driver: use -double option
