Problem is .... -A: It is tested with newest SDL (probably runs on 1.1.7+). - It does NOT work with 1.1.6, 1.1.5 1.1.4 1.1.3 1.0.4 etc, don't ask. - -Q: I am still having trouble compiling with SDL support. gcc says something - about "undefined reference to `SDL_EnableKeyRepeat'" What's 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 DOCS/inttypes.h to MPlayer directory (cp DOCS/inttypes.h .) - try again... if fail, contact us - -Q: I have Pentium III but ./configure doesn't detect SSE -A: Only kernel versions 2.4.x supports SSE (or try latest 2.2.19 or newer, but - be prepared for problems) - -Q: -xy option doesn't work with x11 driver (-vo x11) -A: x11 driver doesn't support scaling, but XF86VidMode support is now - used: you must specify the -vm and the -fs switch, and you're done. - Make sure you have the right Modelines in your XF86Config file, and - try if the DGA driver (and SDL's DGA driver, see VIDEOCARDS) works for you. - It's much faster. If SDL's DGA works too, use that, it'll be EVEN - faster! - -Q: audio goes out of sync playing .avi file -A: try with -bps or -nobps option - if still bad, send me (upload to ftp) that file, I'll check. - -Q: what is the meaning of numbers in the status line? -A: see: - A: 2.1 V: 2.2 A-V: -0.167 ct: 0.042 57 41% 0% 2.6% 0 - - 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) - - video codec cpu usage in percent (for mpeg it includes video_out too!) - - video_out cpu usage for avi, 0 for mpg (see above) - - audio codec cpu usage in percent - - frames needed to drop to maintain A-V sync - Most of them are for debug purposes, and will be removed soon. - -Q: Why is video_out cpu usage zero (0%) for mpeg files? -A: It's not zero, but it's built in into codec, so can't be measured separated. - You should try to play the file using -vo null and then -vo ... and check - the difference to see video_out speed... - -Q: OpenGL (-vo gl) output doesn't work (hangup/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 shit. - it's known to work with Utah-GLX/DRI and Matrox G400 card. Also with - DRI and Radeon card. It won't work with DRI others than these. - it will not work with 3DFX cards because the 256x256 texture size limit. - -Q: I have G200/G400, how to compile/use mga_vid driver? -A: read VIDEOCARDS, INSTALL, README - -Q: What's XMMP? (is it XMMS or XMPS but mispelled?) -A: It's a new project, see http://frozenproductions.com for details - -Q: There are error messages about file not found /usr/lib/win32/.... -A: Download & install w32codec.zip from *our* FTP - (avifile's codec package has different DLL set) - -Q: ...... works with avifile/aviplay while doesn't with MPlayer -A: MPlayer != avifile - The only common thing between these players is the Win32 DLL loader. - The codecs (dll) sets, syncronization, demultiplexing etc is totaly - different and shouldn't be compared. - If something works with aviplay it doesn't mean that MPlayer should do - it and vice versa. - -Q: Indeo 3.x/4.x movies are viewed upside-down!!!? -A: It's a known bug (really it's a bug/limitation of the DLL codec) - Try if your vo driver supports the -flip switch. - -Q: Indeo 3.x,4.x video doesn't work at 32bpp resolutions (16,24 bpp are ok) -A: It's a known bug (really it's a bug/limitation of the DLL codec) - -Q: I've got 'MPlayer interrupted by signal 11' in module audio_setup or - decode_audio. -A: This is highly unlikely, since the mp3lib rewrite. Contact us, it may be - a bug. Possibly it's a damaged file, try with -afm 4 . - -Q: Are there rpm/deb/... packages of MPlayer? -A: You can make a .deb package for yourself, check DOCS/DEBIAN . - It's _STRONGLY_ discouraged to use precompiled packages - of MPlayer, since it (currently) _highly_ depends on compile-time - options and optimizations! - Precompiled packages are COMPLETELY unsupported by the MPlayer team! - -Q: Are there any mailing lists on MPlayer? -A: Yes! See README on how to subscribe them! - -Q: I've found a nasty bug when I tried to play my favourite video!! - Who should I inform? -A: See DOCS/BUGREPORTS - -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 RedHat, and xlib6g-dev* under - Debian. Also check if the /usr/X11 symlink exists (this can be a problem on - Mandrake systems). It can be created with the - $ ln -sf /usr/X11R6 /usr/X11 - command. Also check the /usr/include/X11 link : - $ ln -sf /usr/X11R6/include/X11 /usr/include/X11 - Your distribution may differ from the Linux Filesystem Standard. - -Q: I have problems playing files with ... codec. Can I use'em? -A: Check http://mplayer.sourceforge.net/DOCS/codecs.html, - if it doesn't contain your codec, read - http://mplayer.sourceforge.net/DOCS/CODECS, and contact us. - -Q: What about 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 VIDEOCARDS) - Alternatively, try SDL's DGA driver with '-vo sdl:dga' options. - -Q: Ok, -vo help shows DGA driver, but it is babbling about permissions! - Help me! -A: It works only if running as root! It's a DGA limitation. - You should become to root (su -), and try again. - - Another solution is making mplayer SUID root, but its NOT RECOMMENDED! - 'chown root /usr/local/bin/mplayer' - 'chmod 750 /usr/local/bin/mplayer' - 'chmod +s /usr/local/bin/mplayer' - !!!! BUT STAY TUNED !!!! - This is a *BIG* security risk! *NEVER* do this on a server or on a computer - can be accessed by more people than only you because they can gain root - privilegies through suid root mplayer!!! - !!!! SO YOU HAVE BEEN WARNED ... !!!! - -Q: The fsdga driver doesn't work with my xyz.avi file. Why is that? -A: Because it only works with MPEG. (yet) - -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: Your driver is old, update it. Either download (at least) DRI version 0.6 - from http://dri.sourceforge.net , or use the DRI cvs. - -Q: When using Xvideo, I can't play DivX avis with my Voodoo 3/Banshee ! - It says: - ... - Xvideo image format: 0x32315659 (YV12) planar - Xvideo image format: 0x30323449 (I420) planar - ... -A1: See the previous answer. -A2: Since 0.18pre4 we include libavcodec from the ffmpeg package. It contains - a C language DivX and OpenDivX decoder. The DivX decoder uses YV12 format - for output, thus it should work for you. Compile in libavcodec support. - -Q: Umm, what is "IdegCounter" ? -A: A mixture of a hungarian and an english word. In english, "Ideg" means - "nerve", and is pronounced as something like "ydaegh" . It was first used - to measure the nervousness of A'rpi, after some (umm) "mystic" disappearance - of CVS code ;) - -Q: I can't compile SVGAlib.. I'm using 2.3/2.4 kernel. -A: You have to edit SVGAlib's Makefile.cfg and comment "BACKGROUND = y" out. - -Q: LIRC doesn't work, because ... -A: Are you sure you use "mplayer_lirc" instead of "mplayer" ? - -Q: MPlayer exits with something 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 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 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 switch, everything is ok (but quiet). -A: Those files probably have 48Khz audio, and your soundcard/driver can't play - it correctly. Audio downsampling isn't implemented in MPlayer (yet). - -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. Don't - use MPlayer on different CPU than it was compiled on. - -Q: I have problems with <your window manager> and fullscreen xv/xmga/sdl/x11 - modes.. -A1: Use the -fsmode switch. See example.conf or manpage. - -Q: But it works with avifile ! -A: So what? - -Q: Then avifile is better ! -A: Then use avifile, it has nice GUI and nice C++ code :) - -Q: I got this playing mpeg files: Can't find codec for video format 0x10000001 ! -A: You have old version of codecs.conf at ~/.mplayer/. Upgrade it from DOCS/ - -Q: After starting mplayer under KDE(1/2) 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 the time - until video starts or you disable the arts-daemon in kontrollcenter. - -Q: Subtitles are very nice, the most beautiful I've ever seen, but they slow - down the 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 OSD is flickering! -A: You use a vo driver with single buffering (x11,xv). With xv you can change - the number of buffers in libvo/vo_xv.c : - Increase #define NUM_BUFFERS 1 - -Q: What's the problem with gcc 2.96 ? -A: gcc 2.96 is RedHat's UNOFFICIAL (it can be found only on RedHat sites, or - RedHat distributions) and BUGGY gcc release. gcc 2.96 is TOTALLY - unsupported by MPlayer, because it simply SKIPS MMX codes, it just does not - compile it. Important: this is NOT an MPlayer-specific problem, numerous - other projects (DRI, avifile, etc..) have problems with this shit too. - ** DO NOT USE gcc 2.96 !!! ** - -Q: Is there a hint on how to watch QuickTime and RealMedia movies in mplayer? -A: There's no way to do it. Therefore these formats deserve to die in flames. - Theoretically you can reverse engineer Real codecs built for Linux (they - are available as .so files), but in practice that's really difficult, even - if you know how the compiler used by Real is making assembler code. - As for QuickTime, it's possible to play some old movies and this - capability will be added to mplayer soon, but newer clips are all Sorenson - encoded, and that codec is built-in deep in the QT executable, there's - no way to use it. - -Q: I have an nVidia TNT/TNT2 card, and I have a band with strange colours, - right under the movie! Whose fault is this? -A: It's the nVidia X driver's. These bugs are ONLY with the TNT/TNT2 cards, - and we can't do anything about it, it's not our bug. - -Q: What exactly is this libavcodec? -A: It's from Gerard Lantau's ffmpeg package (http://ffmpeg.sourceforge.net). - It has C language DivX ;-) and OpenDivX codec. Some benchmarks - showed that its DivX seems to be even faster than DirectShow codec without - preprocessing, and only a few percent slower than ProjectMayo's OpenDivX - decoder. It uses YV12 pixel format, so old Voodoo users can use it for YUV. - Also, open the possibility to play DivX on virtually every computer that - has a C compiler. Kinda great stuff, isn't it? |
