0. How to read this documentation

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 TOC (Table of Contents) and search for the topic, read the FAQ, or try grepping though the files.

The main rule of this documentation: if it's not documented, it does not exist. 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 :)

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, VOB, AVI, VIVO, ASF/WMV, QT/MOV, FLI, RM, NuppelVideo, yuv4mpeg, FILM, RoQ files, supported by many native, XAnim, and Win32 DLL codecs. You can watch VideoCD, SVCD, DVD, 3ivx, and even DivX movies too (and you don't need the avifile library at all!). The 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 use GGI and SDL (and this way all their drivers) and some lowlevel card-specific drivers (for Matrox, 3Dfx and Radeon) 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 DVB and DXR3/Hollywood+ ! And what about the nice big antialiased shaded subtitles (10 supported types!!!) with european/ISO 8859-1,2 (hungarian, english, czech, etc), cyrillic, korean fonts, and OSD?

MPlayer is basically GPL, but contains some non-GPL code which is not allowed to be distributed in binary form, and also contains the OpenDivX library which has special license. We are still developing towards GPL.

Distributing MPlayer in the form of binaries and/or binary packages is currently impossible, speaking about both technical and law areas. Detailed information can be found in the second part of this file, and it is recommended to read it.

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 temporarily rebuild their indexes with the -idx 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.

1.2. History

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...

• mpg12play v0.1-v0.3: Sep 22-25, 2000
  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: Sep 28-Oct 20, 2000
  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: Oct 21-Nov 2, 2000
  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: Nov 18-Dec 4, 2000
  It was a pack of two programs: mpg12play v0.95pre6 and my new simple AVI player 'avip' based on avifile's Win32 DLL loader.
• MPlayer v0.10: Jan 1, 2001
  The MPEG and AVI player in a single binary!
• MPlayer v0.11pre series:
  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 v0.17a "The IdegCounter" Apr 27, 2001
  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" Jul 9, 2001
  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 !
• MPlayer 0.50 "The Faszom(C)ounter" Oct 8, 2001
  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!
• MPlayer 0.60 "The RTFMCounter" Jan 3, 2002
  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.

1.3. Installation

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 neccessarily be hard. If you experience a different behaviour 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.

You need a fairly recent system. On Linux, 2.4.x kernels are recommended.

SOFTWARE REQUIREMENTS

• 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 2.95.3 to 2.95.4. NEVER use 2.96 or 3.x.x !!! They generate faulty code. If you decide to change gcc from 2.96, then don't decide in favor of 3.0 juts because it's newer! In some ways it's even worse than 2.96. So downgrade to 2.95.x (downgrade libstdc++ too!) or don't up/downgrade at all (but in this case, be prepared for runtime problems). If you vote for 3.x, try to use the latest version, early releases had various bugs, so be sure you use at least 3.0.3 or 3.1. Detailed information about gcc 2.96's bugs (that are still NOT fixed, they are WORKAROUNDED in MPlayer!) can be found here and in the FAQ !
• XFree86 - suggested version is always the newest (4.2.0). Normally everyone wants this, as starting from XFree86 4.0.2, it contains the XVideo extension (somewhere referred as Xv) which is needed to enable the hardware YUV acceleration (fast image display) on cards that support it. More information available.
  Make sure its development package is installed too otherwise it won't work.
  For some videocards you don't need XFree86. See list below.
• make - suggested version is always the newest (at least 3.79.x). This usually isn't important.
• SDL - it's not mandatory, but can help in some cases (bad audio, videocards that lag strangely with the xv driver). Always use the newest (beginning from 1.2.x). Also can display subtitles under the movie, on the black bar.
• libjpeg - optional JPEG decoder, used by -mf and some qt mov files. Useful for both MPlayer and MEncoder if you plan to work with jpeg files.
• libpng - recommended and default (M)PNG decoder. Required for GUI. Useful for both MPlayer and MEncoder.

CODECS

• libavcodec : If you want to use this DivX3/DivX4/DivX5/etc codec, check the 2.2.1.2 section before compiling. Features :
  
  • you can gain DivX/DivX4/DivX5 playing on non-x86 machines
  • RealVideo 1.0/VIVO/MJPEG/h263/others playing and encoding
  • this codec has the greatest decoding speed for DivX and DivX4/DivX5 movies (even faster than the original DivX4 library itself) ! Recommended!
• Win32 codecs : If you plan to use MPlayer on x86 architecture, you will possibly need them. 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. Features:
  
  • 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)
  • needed if you want to play WMV movies or older (MP42) ASF's
• DivX4/DivX5 : information about this codec is available in the 2.2.1.1 section. If you don't want to encode with it, you possibly don't want this codec as libavcodec (see above) is much faster than this.
  Features :
  • 1 pass or 2 pass encoding with MEncoder
  • can play old DivX3 movies much faster than the Win32 DLL but slower than libavcodec !
  • it's closed-source, and only an x86 version is available.
• XviD : Opensource encoding alternative to Divx4Linux
  Features :
  • 1 pass or 2 pass encoding with MEncoder
  • it's open-source, so not only an x86 version is available.
  • it's about 2 times faster than divx4 when encoding - about the same quality
• The XAnim codecs are the best (full screen, hardware YUV zoom) for decoding 3ivx 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 MPlayer's own Cinepak decoder !

VIDEOCARDS

There are generally two kind of videocards. One kind (the newer cards) has hardware scaling and YUV acceleration support, the other cards don't.

YUV cards

They can display and scale (zoom) the picture to any size that fits in their memory, with small CPU usage (zooming doesn't increase it!), thus you get a nice and very fast fullscreen playing.

• Matrox G200/G400/G450/G550 cards : please see the mga_vid 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. Also check out the Matrox TV-out section. If you are non-Linux user, read Vidix documentation !
• 3Dfx Voodoo3/Banshee cards : please see the 2.3.1.9 section in order to gain big speedup. It is important to do these steps before compiling MPlayer, otherwise no 3Dfx support will be built. Also see the 3dfx TV out section. If you use X, use at least 4.2.0, as 3dfx Xv driver was broken in 4.1.0, and earlier releases!
• ATI cards : see the ATI cards section of the TV-out documentation, to know what features of your card is supported under Linux/MPlayer. If you have a Radeon, Rage128 or Mach64 (Rage XL/Mobility, Xpert98) card, we have a XXX_vid driver for you, with optional TV out ! Check this section ! If you are non-Linux user, read Vidix documentation !
• S3 cards : 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 S3 Xv section for details. Older, Trio cards have no, or slow hardware support.
• Nvidia cards : very bad choice for video playing (NVidia has different opinion!). Nvidia's cards have very cheap and bad quality chips. Moreover, the built-in Nvidia driver in XFree86 doesn't contain support for hardware YUV acceleration for all NVidia cards ! You have to download Nvidia's closed-source drivers from nvidia.com . See details in Nvidia Xv driver section.
• other cards : none of the above?
  • Try if the XFree86 driver (and your card) supports hardware acceleration. See the Xv section for details.
  • If it doesn't, then your card's video features aren't supported under your OS :(
    If it does hardware scaling under Windows, it doesn't mean it will do the same under Linux or other OS, it depends on the drivers! Most manufacturers don't make Linux drivers nor release chip specs - so you're unlucky if using their cards. See next section:

Non-YUV cards

Fullscreen playing can be achieved by either zooming by software (use the option -zoom, but i warn you: this is slooow!), or changing to a smaller videomode, for example to 352x288. If you don't have YUV accel, this latter method is the recommended one. Throughout MPlayer, this behaviour can be switched on by using the -vm option and with the following drivers :

• using XFree86 : see details in DGA driver and X11 driver sections. DGA is recommended! Also try DGA via SDL, sometimes it's better.
• not using XFree86 : try the drivers in the following order : vesa, fbdev, svgalib, aalib.

SOUNDCARDS

• Soundblaster Live! : with this card you can use 4 or 6 (5.1) channels AC3 decoding instead of 2. Read the Software AC3 decoding section. For hardware AC3 passthrough you MUST use ALSA 0.9 oss emulation!
• C-Media with SP/DIF out : hardware AC3 passthrough is possible with these cards, see Hardware AC3 decoding section.
• other cards' features aren't supported by MPlayer. It's very recommended to read the soundcards section !

FEATURES

• For DVD support, you'll have to compile libdvdcss and libdvdread, and in this order! See section 4.2 for more information.
• Decide if you need GUI. If you do, see the 1.4 section before compiling.
• If you want to install MEncoder (our great all-purpose encoder), see the MEncoder section .
• If you have a V4L compatible TV tuner card, and wish to watch/grab and encode movies with MPlayer, read the TV input section.
• There are three timing methods in MPlayer. To use the old method, you don't have to do anything. It uses usleep() to tune A/V sync, with +/- 10ms accuracy. However sometimes the sync has to be tuned even finer. The new timer code uses PC's RTC (Real Time Clock) for this task, because it has precise 1ms timers. This requires root, or a setuid root MPlayer binary (or a little kernel hacking, but that's unadvised). You can see the new timer's efficiency in the status line. The third timer code is turned on with the -softsleep option. It has the efficiency of the RTC, but it doesn't use RTC. On the other hand, it requires more CPU. Note: NEVER install setuid MPlayer binary on a multiuser system! It's a clear way for everyone to gain root.

Then build MPlayer:

    ./configure
    make
    make install

At this point, MPlayer is ready to use. The directory /usr/local/share/mplayer contains the codecs.conf file, which is used to tell the program all the codecs and their capabilities. This file should always be kept uptodate together with the main binary !
Check if you have codecs.conf in your home directory (~/.mplayer/codecs.conf) left from old MPlayer versions, and remove it!

Debian users can build a .deb package for themselves, it's very simple. Just exec fakeroot debian/rules binary in MPlayer's root dir. Detailed instructions can be found here.

ALWAYS browse the output of ./configure, and the configure.log file, they contain info about what will be built, and what won't. You may also want to view config.h and config.mak files.
If you have some libs installed, but not detected by ./configure, then check if you also have the proper header files (usually the -dev packages) and their version matches. The configure.log usually tells you what is missing.

Though not mandatory, the fonts should be installed in order to gain OSD, and subtitle functionality. Download mp-arial-iso-8859-*.zip and/or optional (if exists) language updates. It's VERY RECOMMENDED to check section 1.5 for details.

    mkdir ~/.mplayer/font
    cd ~/.mplayer/font
    unzip mp-arial-iso-8859-1.zip

1.4. What about the GUI?

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 --enable-gui during ./configure . Then, to turn on GUI mode, you either

• use the -gui option
• specify gui=yes in your config file
• ln -s /usr/local/bin/mplayer /usr/local/bin/gmplayer , and call gmplayer instead.

HINT: use the middle button (on 2 button mice press left and right simultaneously) for a popup GTK menu, with DVD playing option!

As MPlayer doesn't have a skin included, you have to download them if you want to use the GUI. See the download page. They should be extracted to the usual system-wide directory (/usr/local/share/mplayer/Skin), or to $HOME/.mplayer/Skin . MPlayer by default looks in these directories for a default named directory, but you can use the -skin newskin option, or the skin=newskin config file directive to use the skin in */Skin/newskin directory.

1.5. Subtitles and OSD

Yes, MPlayer also supports many kinds of subtitles. Currently 10 kinds of subtitle can be used by the subreader code. To see what are these subtitle formats, see subreader.c, line ~30.

MPlayer supports VobSub subtitles. VobSub subtitles consist of a big (some megabytes) .SUB file, and optional .IDX and/or .IFO files. Usage : if you have files like sample.sub, sample.ifo, sample.idx - you have to pass the -vobsub sample -vobsubid 0 options (optionally with pathname, of course). The -vobsubid option is like -sid for DVDs, you can choose between subtitle tracks (languages) with it.

About DVD subtitles, read the DVD section.

MPlayer introduces a new subtitle format called MPsub. It was designed by me (Gabucino). Basically its main feature is being dynamically time-based (although it has frame-based mode too). Example (from DOCS/tech/mpsub.sub) :

# first number : wait this much after previous subtitle disappeared
# second number : display the current subtitle for this many seconds

15 3
A long, long time ago...

0 3
in a galaxy far away...

0 3
Naboo was under an attack.


So you see, the main goal was to make subtitle editing/timing/joining/cutting easy. And, if you - say - get an SSA subtitle but it's badly timed/delayed to your version of the movie, you simply do a mplayer dummy.avi -sub source.ssa -dumpmpsub . A dump.mpsub file will be created in the current directory, which will contain the source subtitle's text, but in MPsub format. Then you can freely add/substract seconds to/from the subtitle.

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:

• 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. 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
  • ftp://ftp.mplayerhq.hu/MPlayer/contrib/fonts/ - various fonts by users
  • http://realtime.ssu.ac.kr/~lethean/mplayer - korean fonts & RAW plugin
• 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)

After that, UNZIP the file you downloaded to ~/.mplayer or $PREFIX/share/mplayer. Then rename or symlink one of them to font (like : ln -s ~/.mplayer/arial-24 ~/.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.

3. Usage

3.1. Command line

MPlayer utilizes a complex playtree. It consists of global options written as first (for example mplayer -vfm 5), and options written after filenames, that apply only to the given filename/URL/whatever (for example mplayer -vfm 5 movie1.avi movie2.avi -vfm 4).
You can group filenames/URLs together using { and }. It's usefull with option -loop: mplayer { 1.avi -loop 2 2.avi } -loop 3 will play files in this order: 1 1 2 1 1 2 1 1 2

	file		mplayer [options] [path/]filename
	files		mplayer [default options] [path/]filename1 [options for filename1] filename2 [options for filename2] ...
	VCD		mplayer [options] -vcd trackno [-cdrom-device /dev/cdrom]
	DVD		mplayer [options] -dvd titleno [-dvd-device /dev/dvd]
	net		mplayer [options] http://site.com/file.asf (playlists can be used too)

Latest versions of MPlayer also accepts VCD and DVD tracks in URL style, just like Xine does: mplayer dvd://1 or mplayer vcd://1

  mplayer -vo x11 /mnt/Films/Contact/contact2.mpg
  mplayer -vcd 2
  mplayer -afm 3 /mnt/DVDtrailers/alien4.vob
  mplayer -dvd 1 -dvd-device /dev/hdc
  mplayer -abs 65536 -delay -0.4 -nobps ~/movies/test.avi

3.3. 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 doesn'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.

3.4. Streaming from network or pipes

MPlayer can play files from network, using the HTTP or MMS protocol.

Playing goes by simply using adding the URL to the command line. MPlayer also honours the HTTP_PROXY environment variable, and uses proxy if available. Proxy usage can also be forced :

mplayer http_proxy://proxy.micorsops.com:3128/http://micorsops.com:80/stream.asf

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 -

Note: it's also recommended to enable CACHE when playback from network:

wget ftp://micorsops.com/something.avi -O - | mplayer -cache 8192 -

4. FAQ section

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.

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

6.5. Silicon Graphics Indigo / IRIX

Reported working. You'll probably have to use the sgi ao driver. Anyone has closer info?

6.6. QNX

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

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

Appendix C - How to report bugs

Appendix D - Known bugs

Special system/cpu-specific bugs/problems:

• 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
• "Internal buffer inconsistency" during MEncoder run:
  Problem: known gcc 2.96 bug, no fix yet. If you have gcc 2.95, you have a libmp3lame library that was compiled with gcc 2.96 (installed from a deb/rpm package?). Check which lib does MEncoder found : ldd mencoder.
• Messed up MP2/MP3 sound on PPC:
  Problem: known GCC miscompilation bug on PPC platforms, no fix yet.
  Workaround: use FFmpeg's (slow) MP1/MP2/MP3 decoder (-ac ffmpeg)
• sig11 in libmpeg2, when scaling+encoding:
  Problem: known GCC 2.95.2 MMX bug, upgrade to 2.95.3.

Various A-V sync and other audio problems:

• 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 eb sure it's soundcard (driver) problem.
• audio buffer problems (buffer size badly detected)
  Workaround: mplayer -abs option
• samplerate problems - maybe your card doesn't support the samplerate used in your files - try the resampling plugin (-aop)
• 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
  Also try -framedrop

• bad file
  Workaround:
  • -ni or -nobps option (for non-interleaved or bad files)
  and/or
  • -mc 0 (required for files with badly interleaved VBR audio)
  and/or
  • -delay option or +/- keys at runtime to adjust delay
  If none of these help, please upload the file, we'll check (and fix).
• 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) or use the resampler plugin
• slow machine
  (if A-V is not around 0, and the last number in the status line increasing)
  Workaround: -framedrop

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

• your file uses an unsupported video codec
  Workaround: read the documentation and help us adding support for it
• auto-selected codec can't decode the file, try to select another using -vc or -vfm options
• you try to play DivX 3.x file with opendivx decoder or XviD (-vc odivx) - install Divx4Linux and recompile player

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

Green image using mga_vid (-vo mga / -vo xmga):
- mga_vid missdetected your card's RAM amount, reload it using mga_ram_size option
