## 5.1 Compilation

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 `config.log` file for details.
Q: What does "No such file or directory" mean?
  A: Probably there is no such file or directory.
Q: What's the problem with gcc 2.96?
  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.
Q: Great, I have gcc 3.0.1 from Red Hat/Mandrake, then I'm fine!
  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.
Q: I tried to compile MPlayer, but I got this output:

        In file included from /usr/include/g++-v3/bits/std_cwchar.h:42,
                         from /usr/include/g++-v3/bits/fpos.h:40,

        `const

  A: Upgrade your glibc to the latest release. On Mandrake, use 2.2.4-8mdk.
Q: ... gcc 2.96 ... (Yes, some people are STILL flaming about gcc 2.96!)
  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.

Q: SDL output doesn't work or compile. The problem is ...
  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!
Q: It doesn't compile, and it misses uint64_t inttypes.h and similar things ...
  A: Copy etc/inttypes.h to the MPlayer directory (`cp etc/inttypes.h .`) and try again ...
Q: I have Linux running on a Pentium III but `./configure` doesn't detect SSE ...
  A: Only kernel versions 2.4.x support SSE (or try 2.2.19 or newer, but be prepared for problems).
Q: I have a G200/G400, how do I compile/use the mga_vid driver?
  A: Read the mga_vid documentation.
Q: Are there rpm/deb/... packages of MPlayer?
  A: You can make a .deb package for yourself, check the Debian packaging section. There are links to official Red Hat RPM packages available on our download page.
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/X11`
  Your distribution may differ from the Filesystem Hierarchy Standard.
Q: I can't compile SVGAlib. I'm using kernel 2.3/2.4 ...
  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 directory`
I 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`.
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: When compiling MEncoder, it segfaults at linking!
  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!
Q: MPlayer dies with segmentation fault upon pthread check!
  A: chmod 644 /usr/lib/libc.so
Q: I'd like to compile MPlayer on Minix!
  A: Me too. :)

## 5.2 General questions

Q: How do I create a proper patch for MPlayer?
  A: We made a short document describing all the necessary details. Please follow the instructions.
Q: How can I support MPlayer development?
  A: We are more than happy to accept your hardware and software donations. They help us in continuously improving MPlayer.
Q: How can I become an MPlayer developer?
  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.
Q: Can I run multiple instances of MPlayer?
  A: Yes. Some video out drivers like xv, dga or (x)mga are exclusive, some are exclusive in combination with certain graphics boards and drivers. You will not be able to run more than one instance of MPlayer with one of those video out drivers. To a lesser degree this also applies to audio drivers. Not all allow playback of multiple streams on the same device.
Q: There is a timer in the upper left corner. How can I get rid of it?
  A: Press `o` and try the `-osdlevel` option.
Q: The `-xy` or `-fs` option doesn't work with the x11 driver (`-vo x11`) ...
  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.
Q: What is the meaning of the numbers on the status line?
  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)
  Most of them are for debug purposes and will be removed at some point.
Q: What if I don't want them to appear?
  A: Use the `-quiet` option and read the man page.
Q: Why is video_out cpu usage zero (0%) for some files?
  A1: 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.
  A2: 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.
Q: There are error messages about file not found `/usr/lib/win32/` ...
  A: Download the Win32 codecs from our codecs page (avifile's codec package has a different DLL set) and install it.
Q: Are there any mailing lists on MPlayer?
  A: Yes. See the bottom of the info page on our homepage to subscribe.
Q: I've found a nasty bug when I tried to play my favorite video! Who should I inform?
  A: Please read the bug reporting guidelines and follow the instructions.
Q: I have problems playing files with the ... codec. Can I use them?
  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: Umm, what is "IdegCounter"?
  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 ;)
Q: And what is "Faszom(C)ounter"?
  A: "Fasz" is a Hungarian word you don't want to know, the others are connected to the perverted minds of the MPlayer developers.
Q: LIRC doesn't work, because ...
  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.
Q: The onscreen display (OSD) is flickering!
  A: You use a vo driver with single buffering (x11,xv). With xv, use the `-double` option. Also try `-vop expand`
Q: What exactly is this libavcodec thing?
  A: See the libavcodec section.
Q: But configure tells me "Checking for libavcodec ... no"!
  A: You need to get libavcodec from FFmpeg's CVS. Read the instructions in the libavcodec section.
Q: Icewm's taskbar keeps covering the movie in fullscreen mode!
  A: This shouldn't happen anymore, if it still does use the `-fstype layer` option and report it to the mplayer-users mailing list.
Q: I can't access the GUI menu. I press right click, but I can't access any menu items!
  A: Are you using FVWM? Try the following:
  Start -> Settings -> Configuration -> Base Configuration
  Set "Use Applications position hints" to "Yes".
Q: How can I run MPlayer in the background?
  A: Use: `mplayer <options> <filename> < /dev/null &`

## 5.3 Playback problems

Q: I can play certain AVIs but I get no sound and this kind of error:

        Detected audio codec: [divx] afm:4 (DivX audio (WMA))
        Requested audio codec family [divx] (afm=4) not available (enable it at
        compile time!)

  A: Probably the audio uses a codec not natively supported by MPlayer. Install the Win32 codec package as described in the README or in the Installation section.
Q: ... works with avifile/aviplay but doesn't with MPlayer.
  A: MPlayer is not avifile. The only common thing between these players is the Win32 DLL loader. The codecs (DLL) set, synchronization, demultiplexing etc is totally different and shouldn't be compared. If something works with aviplay it doesn't mean that MPlayer will work and vice versa.
Q: Audio goes out of sync playing an AVI file.
  A: Try the `-bps` or `-nobps` option. If it does not improve, read this and upload the file to FTP.
Q: MPlayer exits with some error when using l3codeca.acm.
  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 M$ 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 soundcard driver is broken. Consult the documentation to see if you can improve performance.
Q: MPlayer dies with "MPlayer interrupted by signal 4 in module: decode_video".
  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.
Q: I have problems with [your window manager] and fullscreen xv/xmga/sdl/x11 modes ...
  A: Read the bug reporting guidelines and send us a proper bug report.
Q: I got this playing MPEG files: Can't find codec for video format 0x10000001!
  A: You have an old version of codecs.conf at `~/.mplayer/`. Upgrade it from `/etc/`.
  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 kontrol 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 M$ MPEG4v3. Update your codecs.conf.
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`.
Q: I have an MJPEG file which works with other players but displays only a black image in MPlayer.
  A: Disable the Windows DLL in `codecs.conf`, or use the `-vc ffmjpeg` option (compile MPlayer with libavcodec for this to work).
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 misreports its colorspace capacity. Try with YUY2 instead of default YV12 (see the TV input documentation).
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.
Q: I have A/V sync problems. Some of my AVIs play fine, but some play with double speed!
  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 plugin.
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: Update your `codecs.conf`.
Q: I get very strange percentage values (way too big) while playing files on my notebook.
  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.
Q: While playing a movie it suddenly gets jerky and I get the following message:
`Badly interleaved AVI file detected - switching to -ni mode...`
  A: Badly interleaved files and `-cache` don't work well together. Try `-nocache`.

## 5.4 Video/audio driver problems (vo/ao)

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.
Q: What about the DGA driver? I can't find it!
  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 documentation. Alternatively, try SDL's DGA driver with the `-vo sdl:dga` option.
Q: OK, `-vo help` shows DGA driver, but it complains about permissions. Help me!
  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: security risk
  > 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 bugfix #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.
Q: OpenGL (`-vo gl`) output doesn't work (hang/black window/X11 errors/...).
  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.
Q: When I use the GUI with SDL video output, a second video window is created.
  A: Known, don't use SDL for the GUI yet.
Q: Oh the world is cruel ...! SDL has only `x11` target, but not `xv`!
  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: you can force/disable Xv via SDL using `-forcexv` and `-noxv`

## 5.5 DVD playback

Q: What about DVD navigation?
  A: Support for dvdnav in MPlayer is currently broken, normal playback does work, though. If you want to have fancy menus, you will have to use another player like xine or Ogle. If you care about DVD navigation, send a patch.
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.
Q: Can I compile libdvdread and libdvdcss on my sweet SPARC under Solaris?
  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.
Q: What about subtitles? Can MPlayer display them?
  A: Yes. See the DVD chapter of the documentation.
Q: How can I set the region code of my DVD-drive? I don't have Windows!
  A: Use the regionset tool.
Q: Do I need to be (setuid) root/setuid fibmap_mplayer to be able to play a DVD?
  A: No, only for old-style DVD support. However you must have the proper rights on the DVD device entry (in `/dev/`).
Q: Where can I get libdvdread and libdvdcss packages?
  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.
Q: Is it possible to play/encode only selected chapters?
  A: Yes, try the `-chapter` option.
Q: My DVD playback is sluggish!
  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 of the documentation).

## 5.6 Feature requests

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.
Q: I'd like to seek +/- 1 frames instead of 10 seconds.
  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.
Q: Where is the Windows version?
  A: It's not released, and won't be. Look around the Windows scene (open source ASF parsers, open source ASF encoders, etc) and you'll know why. We don't want to go to jail. BTW you can compile it yourself, under Cygwin.
Q: How can I make MPlayer remember the options I use for this particular file?
  A: Create a file named `movie.avi.conf` with the file-specific options in it and put it in `~/.mplayer` or in the same directory as the file.

## 5.7 Encoding

Q: How can I encode?
  A: Read the MEncoder documentation.
Q: How can I create VCDs?
  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.
Q: How can I join two video files?
  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.
Q: I can't encode DVD subtitles into the AVI!
  A: You have to specify the `-sid` option correctly!
Q: MEncoder segfaults on startup!
  A: Upgrade DivX4Linux.
Q: How can I encode only selected chapters from a DVD?
  A: Use the `-chapter` option correctly, like: `-chapter 5-7`
Q: I'm trying to work with 2GB+ files on a VFAT file system. Does it work?
