A: We made a short document describing all the necessary details. Please follow the instructions.
A: Read the translation HOWTO, it should explain everything. You can get further help on the mplayer-docs mailing list.
A: We are more than happy to accept your hardware and software donations. They help us in continuously improving MPlayer.
A: We always welcome coders and documenters. Read the technical documentation to get a first grasp. Then you should subscribe to the mplayer-dev-eng mailing list and start coding. If you want to help out with the documentation, join the mplayer-docs mailing list.
A: We have a modular, handwritten build system. It does a reasonably good job, so why change? Besides, we dislike the auto* tools, just like other people.
Q: Compilation stops with an error message similar to this one:

Q: Compilation stops with an error message similar to this one:
In file included from mplayer.c:34: mw.h: In function `mplMainDraw': mw.h:209: Internal compiler error in print_rtl_and_abort, at flow.c:6458 Please submit a full bug report, with preprocessed source if appropriate.
A: This is a known problem of gcc 3.0.4, upgrade to 3.1 to solve the problem. How to install gcc is described in the gcc 2.96 section.
Q: Configure ends with this text, and MPlayer won't compile!
Your gcc does not support even i386 for '-march' and '-mcpu'
A: Your gcc isn't installed correctly, check the configure.log file for details.
A:
We strongly discourage the use of gcc 2.96!
Read this document for details about why Red Hat
released gcc 2.96 and what the problems are all about. If you still really really
want to use it, be sure to get the latest release and give the
--disable-gcc-checking
option to configure. Remember that you
are on your own from this point. Do not report
bugs, do not ask for help on the mailing lists.
We will not provide any support in case you run
into problems.
A: No, since there have been/are issues with these compilers as well. To check the status of current compilers' MPlayer support, see the Installation section.
A: Quoted from a mail A'rpi sent to the mplayer-users list (the word 'ideg' is described below):
And we have idegs. And our idegcounter overflowed again and again.
Unfortunately MPlayer is out of our control. It's used by lamers, Linux users who can't even use Windows, and never tried to compile a kernel. They installed (with default options) Mandrake or Red Hat or SuSE, and without RTFM'ing they send messages saying 'it doesn't work! help me! please! i'm new to Linux! help! oh! help me!'. We can't stop them, but at least we try to force them to RTFM and to read the messages of ./configure and MPlayer.
And you clever guys come and flame us with gcc 2.96 and binary packages. Instead of helping users or making patches to help solve problems.
Half of our spare/free time is spent by answering silly mails here and making newer tricks and checks to configure to avoid such mails.
And there is a balance. On the one side are you, clever guys, saying we are very bad because we don't like buggy gcc 2.96, and on the other side there are the 'new to Linux' guys who are showing us gcc 2.96 is buggy.
Conclusion: We can't be good. Half the people will always say we are bad.
Maybe we should close the project, make it closed source, commercial, and provide install support for it. then we could leave current work, so development could go faster, and we could earn lots of money with it and buy a big house, etc etc. Do you really want it? It seems.
A: It was tested to work with SDL 1.2.x and may run on SDL 1.1.7+. It does not work with any previous version. So if you choose to use such a version, you are on your own.
Q: I am still having trouble compiling with SDL support. gcc says something about
undefined reference to SDL_EnableKeyRepeat. What now?
A: Where did you install the SDL library? If you installed in /usr/local (the default) then edit the top level config.mak and add -L/usr/local/lib after X_LIBS=. Now type make. You're done!
A: Copy this inttypes.h to /usr/local/include/ or an equivalent place and try again ...
A: Only kernel versions 2.4.x support SSE (or try 2.2.19 or newer, but be prepared for problems).
A: Read the mga_vid section.
Q: Hmm, strange. When loading the mga_vid.o kernel module, I found this in the logs:
Warning: loading mga_vid.o will taint the kernel: no license
A: The latest kernel modutils require a flag indicating the license (mainly to avoid kernel hackers debugging closed source drivers). Upgrade your kernel, modutils and MPlayer.
Q: During 'make', MPlayer complains about X11 libraries. I don't understand, I DO have X installed!?
A: ... but you don't have the X development package installed. Or not correctly. It's called XFree86-devel* under Red Hat, and xlibs-dev under Debian. Also check if the /usr/X11 and /usr/include/X11 symlinks exist (this can be a problem on Mandrake systems). They can be created with these commands:
# ln -sf /usr/X11R6 /usr/X11 # ln -sf /usr/X11R6/include/X11 /usr/include/X11Your distribution may differ from the Filesystem Hierarchy Standard.
A: You have to edit SVGAlib's Makefile.cfg and comment BACKGROUND = y out.
Q: I compiled MPlayer with libdvdcss/libdivxdecore support, but when I try to start it, it says:
error while loading shared libraries: lib*.so.0: cannot load shared object file: No such file or directoryI checked up on the file and it IS there in /usr/local/lib ...
A: Add /usr/local/lib to /etc/ld.so.conf and run ldconfig.
A: This is a linker problem. Upgrading binutils should help (2.11.92.* or newer should be good). Since it is not our fault, please do not report!
A: Yes. See the mailing lists section.
A: Please read the bug reporting guidelines and follow the instructions.
A: Check the codec status, if it doesn't contain your codec, read the codec documentation, especially the codec importing HOWTO and contact us.
Q: When I start playing, I get this message but everything seems fine:
Linux RTC init: ioctl (rtc_pie_on): Permission denied
A: You need root privileges or a specially set up kernel to use the new timing code. For details see the RTC section of the documentation.
A:
You have to use a video output driver that does not employ an overlay to be
able to take a screenshot. Under X11, -vo x11
will do, under
Windows -vo directx:noaccel
works.
A:
Press o and try the -osdlevel
option.
A:
It does, but you have to explicitly specify software scaling (very slow) with the
-zoom
option. You better use XF86VidMode support: You must
specify the -vm
and the -fs
option, and you're
done. Make sure you have the right modelines in your XF86Config
file, and try to make the DGA driver and
SDL's DGA driver work for you. It's much
faster. If SDL's DGA works, use that, it'll be even faster.
A: Example:
A: 2.1 V: 2.2 A-V: -0.167 ct: 0.042 57/57 41% 0% 2.6% 0 4 49%
A: audio position in seconds
V: video position in seconds
A-V: audio-video difference in seconds (delay)
ct: total A-V sync correction done
frames played (counting from last seek)
frames decoded (counting from last seek)
video codec CPU usage in percent (for slices and DR this includes video_out)
video_out CPU usage
audio codec CPU usage in percent
frames needed to drop to maintain A-V sync
current level of image postprocessing (when using
-autoq
)
current cache size used (around 50% is normal)
playback speed as a factor of original speed
A:
It's not zero, but it's called from the codec and thus cannot be measured
separately. You should try to play the file using -vo null
and
then -vo ...
and check the difference to see the video_out speed.
A: You are using Direct Rendering, where the codec renders to the video memory itself. In this case, the decoding percentage contains the display percentage, too.
A: Download the Win32 codecs from our codecs page (avifile's codec package has a different DLL set) and install it.
A: A combination of a Hungarian and an English word. "Ideg" in Hungarian means the same as "nerve" in English, and is pronounced as something like "ydaegh". It was first used to measure the nervousness of A'rpi, after some (umm) "mysterious" disappearance of CVS code ;)
A: "Fasz" is a Hungarian word you don't want to know, the others are connected to the perverted minds of the MPlayer developers.
A: Are you sure you are using mplayer instead of mplayer_lirc? Note that it was mplayer_lirc for a long time, including the 0.60 release, but it was recently changed back to mplayer.
Q: Subtitles are very nice, the most beautiful I've ever seen, but they slow down playing! I know it's unlikely ...
A: After running ./configure, edit config.h and replace #undef FAST_OSD with #define FAST_OSD. Then recompile.
A:
You use a vo driver with single buffering (x11, xv). With xv, use the
-double
option. Also try -vf expand
.
A: See the libavcodec section.
A: You need to get libavcodec from FFmpeg's CVS. Read the instructions in the libavcodec section.
A:
This shouldn't happen anymore, if it still does use the -fstype
layer option and report it to the mplayer-users
mailing list.
A: Are you using FVWM? Try the following:
Start -> Settings -> Configuration -> Base Configuration
Set Use Applications position hints to Yes
A:
You have to use -aid
(audio ID) or -alang
(audio language), -sid
(subtitle ID) or -slang
(subtitle language), for example:
mplayer example.mkv -alang eng -slang eng mplayer example.mkv -aid 1 -sid 1To see which ones are available:
mplayer -vo null -ao null -frames 0 -v filename | grep sid mplayer -vo null -ao null -frames 0 -v filename | grep aid
A:
Try playing the stream with the -playlist
option.
A: Your file is most probably broken or a fake file. If you got it from a friend, and he says it works, try comparing md5sum hashes.
Q: I've just installed MPlayer. When I want to open a video file it causes a fatal error:
Error opening/initializing the selected video_out (-vo) device.How can I solve my problem?
A: Just change your video output device. Issue the following command to get a list of available video output drivers:
mplayer -vo helpAfter you've chosen the correct video output driver, add it to your configuration file. Add
vo = selected_voto ~/.mplayer/config and/or
vo_driver = selected_voto ~/.mplayer/gui.conf.
A: Make sure you have installed fonts properly. Run through the steps in the OSD and subtitle part of the installation section again. If you are using TrueType fonts, verify that you have the freetype library installed. Other things include checking your subtitles in a text editor or with other players. Also try converting them to another format.
A: Do you have a stray codecs.conf file in ~/.mplayer/, /etc/, /usr/local/etc/ or a similar location? Remove it, outdated codecs.conf files can cause obscure problems. MPlayer will use its built-in one instead.
A: There is a bad interaction on Fedora between exec-shield, prelink, and any applications which use Windows DLLs (such as MPlayer).
The problem is that exec-shield randomizes the load addresses of all the system libraries. This randomization happens at prelink time (once every two weeks).
When MPlayer tries to load a Windows DLL it wants to put it at a specific address (0x400000). If an important system library happens to be there already, MPlayer will crash. (A typical symptom would be a segmentation fault when trying to play Windows Media 9 files.)
If you run into this problem you have two options:
Wait two weeks. It might start working again.
Relink all the binaries on the system with different prelink options. Here are step by step instructions:
Edit /etc/syconfig/prelink and change
PRELINK_OPTS=-mR
to
PRELINK_OPTS="-mR --no-exec-shield"
touch /var/lib/misc/prelink.force
/etc/cron.daily/prelink (This relinks all the applications, and it takes quite a while.)
execstack -s /path/to/mplayer (This turns off exec-shield for the MPlayer binary.)
A: MPlayer is not xine/avifile/.... Although these players have some code in common, the codecs (DLL) set, synchronization, demultiplexing etc is different and should not be compared. If you have a file MPlayer fails to play correctly but works in another player, please read the bug reporting guidelines and upload the file to our FTP server.
A:
Try the -bps
or -nobps
option. If it does not
improve, read this and upload the file to FTP.
A: Check ldd /usr/local/bin/mplayer output. If it contains
libc.so.6 => /lib/libc.so.6 (0x4???????)where "?" is any number then it's OK, the error is not here. If it is:
libc.so.6 => /lib/libc.so.6 (0x00??????)then there is a problem with your kernel/libc. Maybe you are using some security patches (for example Solar Designer's OpenWall patch) which forces loading libraries to very low addresses. Because l3codeca.acm is a non-relocatable DLL, it must be loaded to 0x00400000, we can't change this. You should use a non-patched kernel, or use MPlayer's
-afm 1
option to disable using l3codeca.acm.
Q:
My computer plays MS DivX AVIs with resolutions ~ 640x300 and stereo MP3 sound
too slow. When I use -nosound
option, everything is OK (but quiet).
A: Your machine is too slow or your sound card driver is broken. Consult the documentation to see if you can improve performance.
A: Try running MPlayer on the machine you compiled on. Or recompile with runtime CPU detection (./configure --enable-runtime-cpudetection). Don't use MPlayer on a CPU different from the one it was compiled on, without using the feature mentioned just now.
A: Read the bug reporting guidelines and send us a proper bug report.
A:
You have an old version of codecs.conf in
~/.mplayer/,
/etc/,
/usr/local/etc/ or similar. Remove it,
it's not needed anymore.
OR you have the vc=
option or
something similar in your config file(s).
Q: When starting MPlayer under KDE I just get a black screen and nothing happens. After about one minute the video starts playing.
A:
The KDE arts sound daemon is blocking the sound device. Either wait until the
video starts or disable the arts-daemon in control center. If you want to use
arts sound, specify audio output via our native arts audio driver
(-ao arts
). If it fails or isn't compiled in, try SDL
(-ao sdl
) and make sure your SDL can handle arts sound. Yet
another option is to start MPlayer with artsdsp.
Q:
I have an AVI that produces a gray screen when played with -vc odivx
and a green one with -vc divx4
.
A: It's not a DivX file, but an MS MPEG4v3. If you have an old version of codecs.conf in ~/.mplayer/, /etc/, /usr/local/etc/ or similar, remove it.
Q: When I play this movie I get video-audio desync and/or MPlayer crashes with the following message:
DEMUXER: Too many (945 in 8390980 bytes) video packets in the buffer!
A: This can have multiple reasons.
Your CPU and/or video card and/or bus is too slow. MPlayer displays a message if this is the case (and the dropped frames counter goes up fast).
If it is an AVI, maybe it has bad interleaving. Try the -ni
option.
Your sound driver is buggy, or you use ALSA 0.5 with -ao oss
.
See the sound card section.
The AVI has a bad header, try the -nobps
option, and/or -mc 0
.
A:
Use another codec to play the file, try -vc ffmjpeg
.
Q: When I try to grab from my tuner, it works, but colors are strange. It's OK with other applications.
A: Your card probably reports some colorspaces as supported when in fact it does not support them. Try with YUY2 instead of the default YV12 (see the TV section).
A: You have a buggy sound card/driver. Most likely it's fixed at 44100Hz, and you try to play a file which has 22050Hz audio. Try the resample audio filter.
Q: All the WMV (or other..) files I play create a green/gray window and there is only sound! MPlayer prints:
Detected video codec: [null] drv:0 (NULL codec (no decoding))
A: If you have an old version of codecs.conf in ~/.mplayer/, /etc/, /usr/local/etc/ or similar, remove it.
A: It's an effect of the power management / power saving system of your notebook (BIOS, not kernel). Plug the external power connector in before you power on your notebook. You can also try whether cpufreq (a SpeedStep interface for Linux) helps you.
Q: The audio/video gets totally out of sync when I run MPlayer as root on my notebook. It works normal when i run it as a user.
A:
This is again a power management effect (see above). Plug the external power
connector in before you power on your notebook
or use the -nortc
option.
A:
After setting up your
asoundrc
you have to use -ao alsa:device=dmix
.
Q: I have no sound when playing a video and get error messages similar to this one:
AO: [oss] 44100Hz 2ch Signed 16-bit (Little-Endian) audio_setup: Can't open audio device /dev/dsp: Device or resource busy couldn't open/init audio device -> NOSOUND Audio: no sound!!! Start playing...
A:
Are you running KDE or GNOME with the ARTS or ESD sound daemon? Try disabling
the sound daemon or use the -ao arts
or -ao esd
option to make MPlayer use ARTS or ESD.
A:
./configure autodetects your DGA driver. If -vo help
doesn't show DGA, then there's a problem with your X installation. Try
./configure --enable-dga and read the
DGA section. Alternatively, try SDL's DGA driver
with the -vo sdl:dga
option.
A: It works only if running as root! It's a DGA limitation. You should become root (su -), and try again. Another solution is making MPlayer SUID root, but it's not recommended!
chown root /usr/local/bin/mplayer chmod 755 /usr/local/bin/mplayer chmod +s /usr/local/bin/mplayer
Warning |
This is a big security risk! Never do this on a server or on a computer that you do not control completely because other users can gain root privileges through SUID root MPlayer. You have been warned. |
Q: When using XVideo, my Voodoo 3/Banshee says:
X Error of failed request: BadAccess (attempt to access private resource denied) Major opcode of failed request: 147 (MIT-SHM) Minor opcode of failed request: 1 (X_ShmAttach) Serial number of failed request: 26 Current serial number in output stream:27
A: The tdfx driver in XFree86 4.0.2/4.0.3 had this bug. This was solved by bug fix #621 of the XFree86 4.1.0 CVS log. So upgrade to XFree86 4.1.0 or later. Alternatively, either download (at least) DRI version 0.6 from the DRI homepage, or use CVS DRI.
A: Your OpenGL driver doesn't support dynamic texture changes (glTexSubImage). It's known not to work with nVidia's binary mess. It's known to work with Utah-GLX/DRI and Matrox G400 cards. Also with DRI and Radeon cards. It won't work with DRI and other cards. it will not work with 3DFX cards because of the 256x256 texture size limit.
Q: I have an nVidia TNT/TNT2 card, and I have a band with strange colors, right under the movie! Whose fault is this?
A: This is a bug of nVidia's binary X driver. These bugs appear ONLY with the TNT/TNT2 cards, and we can't do anything about it. To fix the problem, upgrade to the latest nVidia binary driver version. If still bad, complain to nVidia!
Q: I have an nVidia XYZ card, and when I click on the GUI's display window to toggle displaying the GUI panel, a black square appears where I clicked. I have the newest driver.
A: Yes, nVidia corrected a previous bug (above), and introduced a new one. Let's congratulate them. UPDATE: According to nVidia, this has already been fixed.
A:
Try that x11 target again. Now try -vo x11
-fs -zoom
. See the difference? No?! OK, here comes the enlightenment:
SDL's x11 target uses xv when available, you don't have
to worry about it ... Note: With SDL you can force/disable Xv using
-forcexv
and -noxv
.
A: MPlayer does not support DVD menus due to serious architectural limitations that prevent proper handling of still images and interactive content. If you want to have fancy menus, you will have to use another player like xine, vlc or Ogle. If you want to see DVD navigation in MPlayer you will have to implement it yourself, but be aware that it is a major undertaking.
Q: While playing a DVD, I encountered this error:
mplayer: ifo_read.c:1143: ifoRead_C_ADT_internal: Assertion nfo_length / sizeof(cell_adr_t) >= c_adt->nr_of_vobs' failed.
A: This is a known libdvdread 0.9.1/0.9.2 bug. Use libmpdvdkit2, which is present in MPlayer source, and used by default.
A: Who knows ... It's said to work, so please test it and send feedback. Refer to the documentation of libdvdread and its homepage as well. We're not the authors of libdvdread. Use libmpdvdkit2, which is present in MPlayer source, and used by default.
A: Yes. See the DVD chapter.
A: Use the regionset tool.
A: No. However you must have the proper rights on the DVD device entry (in /dev/).
A: You don't need to. Use libmpdvdkit2, which is present in the MPlayer source, and used by default. You can get the mentioned packages from the Ogle site.
A:
Use the -cache
option (described in the man page) and try
enabling DMA for the DVD drive with the hdparm tool (described
in the CD chapter).
Q: If MPlayer is paused and I try to seek or press any key at all, MPlayer ceases to be paused. I would like to be able to seek in the paused movie.
A: This is very tricky to implement without losing A/V synchronization. All attempts have failed so far, but patches are welcome.
A: This won't be done. It was, but then it messed up A/V sync. Feel free to implement it, and send a patch. Don't ask for it.
A: Read the MEncoder section.
A: Try the mencvcd script from the TOOLS subdirectory. With it you can encode DVDs or other movies to VCD or SVCD format and even burn them directly to CD.
A: This has been discussed to no end on mplayer-users. Go search the archives for a complete answer. This is a complicated topic and your mileage may vary a lot depending on the kind of files you want to merge. MPEGs can be concatenated into a single file with luck. For AVIs there are two tools, avidemux and avimerge (part of the transcode tool set), available that might do the job. You can also try MEncoder if you have two files sharing the same dimensions and codec. Try
cat file1 file2 > file3 mencoder -ovc copy -oac copy -o out.avi -forceidx file3.avi
Q: My tuner works, I can hear the sound and watch the video with MPlayer, but MEncoder doesn't encode audio!
A: TV audio encoding for Linux is currently unimplemented, we're working on it. At the moment it works only on BSD.
A:
Use the -chapter
option correctly, like: -chapter 5-7
A: No, VFAT doesn't support 2GB+ files.
A: Because the bitrate you encoded the audio with is too large to fit the movie on any CD. Check if you have libmp3lame installed properly.
A:
Because ASF uses variable frame rate but AVI uses a fixed one, you
have to set it by hand using -ofps
.
A:
Just pass the -sub <filename>
(or -sid
,
respectively) option to MEncoder.
A: It's not possible directly, but you can try this (note the & at the end of mplayer command):
mkfifo encode mplayer -ao pcm -aofile encode dvd://1 & lame your_opts encode music.mp3 rm encodeThis allows you to use any encoder, not only LAME, just replace lame with your favorite audio encoder in the above command.
