And our idegcounter overflowed again and again.</P> - - <P>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.</P> - - <P>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.</P> - - <P>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.</P> - - <P>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.</P> - - <P>Conclusion: We can't be good. Half the people will always say we are bad.</P> - - <P>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.</P> - </BLOCKQUOTE> - </DD> - <DD> </DD> - - <DT>Q: SDL output doesn't work or compile. The problem is ...</DT> - <DD>A: It was tested to work with SDL 1.2.x and may run on SDL 1.1.7+. - It does <B>not</B> work with any previous version. So if you choose to use - such a version, you are on your own.</DD> - <DD> </DD> - - <DT>Q: I am still having trouble compiling with SDL support. gcc says - something about "undefined reference to `SDL_EnableKeyRepeat'". What - now?</DT> - <DD>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!</DD> - <DD> </DD> - - <DT>Q: It doesn't compile, and it misses uint64_t inttypes.h and similar - things ...</DT> - <DD>A: Copy etc/inttypes.h to the MPlayer directory - (<CODE>cp etc/inttypes.h .</CODE>) and try again ...</DD> - <DD> </DD> - - <DT>Q: I have Linux running on a Pentium III but <CODE>./configure</CODE> - doesn't detect SSE ...</DT> - <DD>A: Only kernel versions 2.4.x support SSE (or try 2.2.19 or newer, but - be prepared for problems).</DD> - <DD> </DD> - - <DT>Q: I have a G200/G400, how do I compile/use the mga_vid driver?</DT> - <DD>A: Read the <A HREF="video.html#mga_vid">mga_vid documentation</A>.</DD> - <DD> </DD> - - <DT>Q: Are there rpm/deb/... packages of MPlayer?</DT> - <DD>A: You can make a .deb package for yourself, check the - <A HREF="documentation.html#debian">Debian packaging</A> section. - There are links to official Red Hat RPM packages available on our - <A HREF="http://www.mplayerhq.hu/homepage/dload.html">download page</A>.</DD> - <DD> </DD> - - <DT>Q: During 'make', MPlayer complains about X11 libraries. I don't - understand, I DO have X installed!?</DT> - <DD>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 <CODE>/usr/X11</CODE> and <CODE>/usr/include/X11</CODE> - symlinks exist (this can be a problem on Mandrake systems). They can be - created with these commands:<BR> - <CODE>$ ln -sf /usr/X11R6 /usr/X11</CODE><BR> - <CODE>$ ln -sf /usr/X11R6/include/X11 /usr/include/X11</CODE><BR> - Your distribution may differ from the - <A HREF="http://www.pathname.com/fhs/">Filesystem Hierarchy Standard</A>.</DD> - <DD> </DD> - - <DT>Q: I can't compile SVGAlib.

When loading the mga_vid.o kernel module, I found this in - the logs:<BR> - <CODE>Warning: loading mga_vid.o will taint the kernel: no license</CODE></DT> - <DD>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.</DD> - <DD> </DD> - - <DT>Q: When compiling MEncoder, it segfaults at linking!</DT> - <DD>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 <B>not</B> - report!</DD> - <DD> </DD> - - <DT>Q: MPlayer dies with segmentation fault upon pthread check!</DT> - <DD>A: chmod 644 /usr/lib/libc.so</DD> - <DD> </DD> - - <DT>Q: I'd like to compile MPlayer on Minix!</DT> - <DD>A: Me too. :)</DD> - -</DL> - - -<H2><A NAME="general">5.2 General questions</A></H2> - -<DL> - - <DT>Q: How do I create a proper patch for MPlayer?</DT> - <DD>A: We made a <A HREF="tech/patches.txt">short document</A> describing - all the necessary details. Please follow the instructions.</DD> - <DD> </DD> - - <DT>Q: How can I support MPlayer development?</DT> - <DD>A: We are more than happy to accept your hardware and software - <A HREF="http://www.mplayerhq.hu/homepage/donations.html">donations</A>. - They help us in continuously improving MPlayer.</DD> - <DD> </DD> - - <DT>Q: How can I become an MPlayer developer?</DT> - <DD>A: We always welcome coders and documenters. Read the - <A HREF="tech/">technical documentation</A> to get a first grasp. Then you - should subscribe to the - <A HREF="http://mplayerhq.hu/mailman/listinfo/mplayer-dev-eng">mplayer-dev-eng</A> - mailing list and start coding.</DD> - <DD> </DD> - - <DT>Q: Can I run multiple instances of MPlayer?</DT> - <DD>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.</DD> - <DD> </DD> - - <DT>Q: There is a timer in the upper left corner. How can I get rid of it?</DT> - <DD>A: Press <CODE>o</CODE> and try the <CODE>-osdlevel</CODE> option.</DD> - <DD> </DD> - - <DT>Q: The <CODE>-xy</CODE> or <CODE>-fs</CODE> option doesn't work with the - x11 driver (<CODE>-vo x11</CODE>) ...</DT> - <DD>A: It does, but you have to explicitly specify software scaling (very - slow) with the <CODE>-zoom</CODE> option. You better use XF86VidMode - support: You must specify the <CODE>-vm</CODE> and the <CODE>-fs</CODE> - option, and you're done. Make sure you have the right modelines in your - XF86Config file, and try to make the <A HREF="video.html#dga">DGA driver</A> - and <A HREF="video.html#sdl">SDL's DGA driver</A> work for you. - It's much faster. If SDL's DGA works, use that, it'll be even faster.</DD> - <DD> </DD> - - <DT>Q: What is the meaning of the numbers on the status line?</DT> - <DD>A: Example: - <CODE>A: 2.1 V: 2.2 A-V: -0.167 ct: 0.042 57/57 41% 0% 2.6% 0 4 49%</CODE> - <UL> - <LI>A: audio position in seconds</LI> - <LI>V: video position in seconds</LI> - <LI>A-V: audio-video difference in seconds (delay)</LI> - <LI>ct: total A-V sync correction done</LI> - <LI>frames played (counting from last seek)</LI> - <LI>frames decoded (counting from last seek)</LI> - <LI>video codec cpu usage in percent (for slices and DR this includes - video_out)</LI> - <LI>video_out cpu usage</LI> - <LI>audio codec cpu usage in percent</LI> - <LI>frames needed to drop to maintain A-V sync</LI> - <LI>current level of image postprocessing (when using <CODE>-autoq</CODE>)</LI> - <LI>current cache size used (around 50% is normal)</LI> - </UL> - Most of them are for debug purposes and will be removed at some point.</DD> - <DD> </DD> - - <DT>Q: What if I don't want them to appear?</DT> - <DD>A: Use the <CODE>-quiet</CODE> option and read the man page.</DD> - <DD> </DD> - - <DT>Q: Why is video_out cpu usage zero (0%) for some files?</DT> - <DD>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 - <CODE>-vo null</CODE> and then <CODE>-vo ...</CODE> and check the - difference to see the video_out speed.</DD> - <DD>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.</DD> - <DD> </DD> - - <DT>Q: There are error messages about file not found - <CODE>/usr/lib/win32/</CODE> ...</DT> - <DD>A: Download the Win32 codecs from our - <A HREF="http://www.mplayerhq.hu/MPlayer/releases/codecs/">codecs page</A> - (avifile's codec package has a different DLL set) and install it.</DD> - <DD> </DD> - - <DT>Q: Are there any mailing lists on MPlayer?</DT> - <DD>A: Yes. See the bottom of the info page on - <A HREF="http://www.mplayerhq.hu/homepage/info.html">our homepage</A> to - subscribe.</DD> - <DD> </DD> - - <DT>Q: I've found a nasty bug when I tried to play my favorite video! - Who should I inform?</DT> - <DD>A: Please read the <A HREF="bugreports.html">bug reporting guidelines</A> - and follow the instructions.</DD> - <DD> </DD> - - <DT>Q: I have problems playing files with the ... codec. Can I use them?</DT> - <DD>A: Check the - <A HREF="http://www.mplayerhq.hu/DOCS/codecs-status.html">codec status</A>, - if it doesn't contain your codec, read the - <A HREF="codecs.html">codec documentation</A>, especially the - <A HREF="codecs.html#importing">codec importing HOWTO</A> and contact us.</DD> - <DD> </DD> - - <DT>Q: Umm, what is "IdegCounter"?</DT> - <DD>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 ;)</DD> - <DD> </DD> - - <DT>Q: And what is "Faszom(C)ounter"?</DT> - <DD>A: "Fasz" is a Hungarian word you don't want to know, the others are - connected to the perverted minds of the MPlayer developers.</DD> - <DD> </DD> - - <DT>Q: LIRC doesn't work, because ...</DT> - <DD>A: Are you sure you are using <CODE>mplayer</CODE> instead of - <CODE>mplayer_lirc</CODE>? Note that it was <CODE>mplayer_lirc</CODE> for a - long time, including the 0.60 release, but it was recently changed back to - <CODE>mplayer</CODE>.</DD> - <DD> </DD> - - <DT>Q: Subtitles are very nice, the most beautiful I've ever seen, but they - slow down playing! I know it's unlikely ...</DT> - <DD>A: After running <CODE>./configure</CODE>, edit <CODE>config.h</CODE> and - replace <CODE>#undef FAST_OSD</CODE> with <CODE>#define FAST_OSD</CODE>. - Then recompile.</DD> - <DD> </DD> - - <DT>Q: The onscreen display (OSD) is flickering!</DT> - <DD>A: You use a vo driver with single buffering (x11,xv). With xv, - use the <CODE>-double</CODE> option. Also try <CODE>-vop expand</CODE></DD> - <DD> </DD> - - <DT>Q: What exactly is this libavcodec thing?</DT> - <DD>A: See the <A HREF="codecs.html#libavcodec">libavcodec section</A>.</DD> - <DD> </DD> - - <DT>Q: But configure tells me "Checking for libavcodec ... no"!</DT> - <DD>A: You need to get libavcodec from FFmpeg's CVS. Read the instructions in - the <A HREF="codecs.html#libavcodec">libavcodec section</A>.</DD> - <DD> </DD> - - <DT>Q: Icewm's taskbar keeps covering the movie in fullscreen mode!</DT> - <DD>A: This shouldn't happen anymore, if it still does use the - <CODE>-fstype layer</CODE> option and report it to the - <A HREF="http://mplayerhq.hu/pipermail/mplayer-users/">mplayer-users</A> - mailing list.</DD> - <DD> </DD> - - <DT>Q: I can't access the GUI menu. I press right click, but I can't access - any menu items!</DT> - <DD>A: Are you using FVWM? Try the following:<BR> - Start -> Settings -> Configuration -> Base Configuration<BR> - Set "Use Applications position hints" to "Yes".</DD> - <DD> </DD> - - <DT>Q: How can I run MPlayer in the background?</DT> - <DD>A: Use: <CODE>mplayer <options> <filename> < /dev/null &</CODE></DD> - -</DL> - - -<H2><A NAME="playback">5.3 Playback problems</A></H2> - -<DL> - - <DT>Q: I can play certain AVIs but I get no sound and this kind of error: - <PRE> - Detected audio codec: [divx] afm:4 (DivX audio (WMA)) - Requested audio codec family [divx] (afm=4) not available (enable it at - compile time!) - </PRE> - </DT> - <DD>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 <A HREF="documentation.html#installation">Installation</A> section.</DD> - <DD> </DD> - - <DT>Q: ... works with avifile/aviplay but doesn't with MPlayer.</DT> - <DD>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.</DD> - <DD> </DD> - - <DT>Q: Audio goes out of sync playing an AVI file.</DT> - <DD>A: Try the <CODE>-bps</CODE> or <CODE>-nobps</CODE> option. If it does not - improve, read <A HREF="bugreports.html">this</A> and upload the file to FTP.</DD> - <DD> </DD> - - <DT>Q: MPlayer exits with some error when using l3codeca.acm.</DT> - <DD>A: Check <CODE>ldd /usr/local/bin/mplayer</CODE> output. If it contains<BR> - <CODE>libc.so.6 => /lib/libc.so.6 (0x4???????)</CODE><BR> - where "?" is any number then it's OK, the error is not here. If it is:<BR> - <CODE>libc.so.6 => /lib/libc.so.6 (0x00??????)</CODE><BR> - 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 <CODE>-afm 1</CODE> option to disable using - l3codeca.acm.</DD> - <DD> </DD> - - <DT>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).</DT> - <DD>A: Your machine is too slow or your soundcard driver is broken. Consult - the documentation to see if you can improve performance.</DD> - <DD> </DD> - - <DT>Q: MPlayer dies with "MPlayer interrupted by signal 4 in module: - decode_video".</DT> - <DD>A: Try running MPlayer on the machine you compiled on. Or recompile - with runtime CPU detection - (<CODE>./configure --enable-runtime-cpudetection</CODE>). Don't - use MPlayer on a CPU different from the one it was compiled on, - without using the feature mentioned just now.</DD> - <DD> </DD> - - <DT>Q: I have problems with [your window manager] and fullscreen - xv/xmga/sdl/x11 modes ...</DT> - <DD>A: Read the <A HREF="bugreports.html">bug reporting guidelines</A> and - send us a proper bug report.</DD> - <DD> </DD> - - <DT>Q: I got this playing MPEG files: Can't find codec for video format - 0x10000001!</DT> - <DD>A: You have an old version of codecs.conf at <CODE>~/.mplayer/</CODE>. - Upgrade it from <CODE>/etc/</CODE>.<BR> - <B>OR</B> you have the <CODE>vc=</CODE> option or something similar in your - config file(s).</DD> - <DD> </DD> - - <DT>Q: When starting MPlayer under KDE I just get a black screen and nothing - happens. After about one minute the video starts playing.</DT> - <DD>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 (<CODE>-ao arts</CODE>). If it fails or isn't compiled in, try SDL - (<CODE>-ao sdl</CODE>) and make sure your SDL can handle arts sound. Yet - another option is to start MPlayer with artsdsp.</DD> - <DD> </DD> - - <DT>Q: I have an AVI that produces a gray screen when played with - <CODE>-vc odivx</CODE> and a green one with <CODE>-vc divx4</CODE>.</DT> - <DD>A: It's not a DivX file, but an M$ MPEG4v3. Update your codecs.conf.</DD> - <DD> </DD> - - <DT>Q: When I play this movie I get video-audio desync and/or MPlayer crashes - with the following message:<BR> - <CODE>DEMUXER: Too many (945 in 8390980 bytes) video packets in the buffer!</CODE></DT> - <DD>A: This can have multiple reasons. - <UL> - <LI>Your CPU <B>and/or</B> video card <B>and/or</B> bus is too slow. - MPlayer displays a message if this is the case (and the dropped - frames counter goes up fast).</LI> - <LI>If it is an AVI, maybe it has bad interleaving. Try the - <CODE>-ni</CODE> option.</LI> - <LI>Your sound driver is buggy, or you use ALSA 0.5 with <CODE>-ao oss</CODE>. - See the <A HREF="sound.html">sound card section</A>.</LI> - <LI>The AVI has a bad header, try the <CODE>-nobps</CODE> option, and/or - <CODE>-mc 0</CODE>.</LI> - </UL></DD> - <DD> </DD> - - <DT>Q: I have an MJPEG file which works with other players but displays only a - black image in MPlayer.</DT> - <DD>A: Disable the Windows DLL in <CODE>codecs.conf</CODE>, or use the - <CODE>-vc ffmjpeg</CODE> option (compile MPlayer with libavcodec for this - to work).</DD> - <DD> </DD> - - <DT>Q: When I try to grab from my tuner, it works, but colors are strange. - It's OK with other applications.</DT> - <DD>A: Your card probably misreports its colorspace capacity. Try with YUY2 - instead of default YV12 (see the <A HREF="documentation.html#tv">TV input - documentation</A>).</DD> - <DD> </DD> - - <DT>Q: When I start playing, I get this message but everything seems fine:<BR> - <CODE>Linux RTC init: ioctl (rtc_pie_on): Permission denied</CODE></DT> - <DD>A: You need root privileges or a - specially set up kernel to use the new timing code. For details see the - <A HREF="documentation.html#rtc">RTC section</A> of the documentation.</DD> - <DD> </DD> - - <DT>Q: I have A/V sync problems. Some of my AVIs play fine, but some play with - double speed!</DT> - <DD>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.

MPlayer prints:<BR> - <CODE>Detected video codec: [null] drv:0 (NULL codec (no decoding))</CODE></DT> - <DD>A: Update your <CODE>codecs.conf</CODE>.</DD> - <DD> </DD> - - <DT>Q: I get very strange percentage values (way too big) while playing files - on my notebook.</DT> - <DD>A: It's an effect of the power management / power saving system of your - notebook (BIOS, not kernel). Plug the external power connector in - <B>before</B> you power on your notebook. You can also try whether - <A HREF="http://www.brodo.de/cpufreq/">cpufreq</A> (a SpeedStep interface - for Linux) helps you.</DD> - <DD> </DD> - - <DT>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.</DT> - <DD>A: This is again a power management effect (see above).

This was solved - by <A HREF="http://www.xfree86.org/cvs/changes_4_1.html">bugfix #621 of the - XFree86 4.1.0 CVS log</A>. So upgrade to XFree86 4.1.0 or later. - Alternatively, either download (at least) DRI version 0.6 from the - <A HREF="http://dri.sourceforge.net">DRI homepage</A>, or use CVS DRI.</DD> - <DD> </DD> - - <DT>Q: OpenGL (<CODE>-vo gl</CODE>) output doesn't work (hang/black window/X11 - errors/...).</DT> - <DD>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.</DD> - <DD> </DD> - - <DT>Q: I have an nVidia TNT/TNT2 card, and I have a band with strange colors, - right under the movie! Whose fault is this?</DT> - <DD>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!</DD> - <DD> </DD> - - <DT>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.</DT> - <DD>A: Yes, nVidia corrected a previous bug (above), and introduced a new one. - Let's congratulate them.
