- - 5. FAQ section - - - 5.1. Compilation - - 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: Great, I have gcc 3.0.1 from RedHat/Mandrake, then I'm fine--! - A: No :) Their gcc 3.0.1 was compiled with gcc 2.96, so they are - buggy shit too. - - Q: Now then. What should I use? - A: Any of gcc 2.95 series. - - Q: SDL output doesn't work or compile. 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 etc/inttypes.h to MPlayer directory (cp etc/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: I have G200/G400, how to compile/use mga_vid driver? - A: Read all this documentation. - - Q: Are there rpm/deb/... packages of MPlayer? - A: You can make a .deb package for yourself, check section 6.1 . - 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: 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: 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 RTFM) - Alternatively, try SDL's DGA driver with '-vo sdl:dga' options. - - 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: I compiled MPlayer with libcss/libdivxdecore support, but when - I try to start it, it says : - > error while loading shared libraries: libcss.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: What are you doing on Linux? Can't you install a library? Why do - we get these questions? It's not MPlayer specific at all! Add - /usr/local/lib to /etc/ld.so.conf and run ldconfig . - Or install it to /usr/lib , because if you can't solve the /usr/local - problem, you are careless enough to do such things. - - - 5.2. General questions - - Q: What about DVD playing ? - A: Read the CD/DVD section . - - 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 RTFM) works for you. - It's much faster. If SDL's DGA works too, use that, it'll be EVEN - faster! - - 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: 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: Are there any mailing lists on MPlayer? - A: Yes! See RTFM 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 Appendix C . - - Q: I have problems playing files with ... codec. Can I use'em? - A: Check http://mplayerhq.hu/MPlayer/DOCS/codecs.html, - if it doesn't contain your codec, read - http://mplayerhq.hu/MPlayer/DOCS/CODECS, and contact us. - - 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: LIRC doesn't work, because ... - A: Are you sure you use "mplayer_lirc" instead of "mplayer" ? - - 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, - use -double option. - - 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 alpha 47 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 DivX4 - 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? - - Q: But configure tells me "Checking for libavcodec ... no"! - A: You need to get libavcodec from FFmpeg's CVS. Read the instructions in - the ffmpeg section . - - - 5.3. File playing problems - - 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: 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: 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: 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). - Maybe use the SDL driver, with -ao:sdl +

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 etc/ - - 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. - If you want to use arts sound, specify audio output via 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 plays with grey screen with -vc odivx, and green - with -vc divx4 . - A: It's not a DivX file, but an M$ MPEG4v3 . Update your codecs.conf. - - - 5.4. Video/audio driver problems (vo/ao) - - 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: 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 support 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: 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 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. - - - 5.5. Feature requests - - 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:	+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:	+Great, I have gcc 3.0.1 from RedHat/Mandrake, then I'm fine--! +
	A:	+No :) Their gcc 3.0.1 was compiled with gcc 2.96, so they are +buggy shit too. +

	Q:	+Now then. What should I use? +
	A:	+Any of gcc 2.95 series. +

	Q:	+SDL output doesn't work or compile. 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 etc/inttypes.h to MPlayer directory (cp etc/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:	+I have G200/G400, how to compile/use mga_vid driver? +
	A:	+Read all this documentation. +

	Q:	+Are there rpm/deb/... packages of MPlayer? +
	A:	+You can make a .deb package for yourself, check section 6.1. +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:	+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:	+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 RTFM) +Alternatively, try SDL's DGA driver with '-vo sdl:dga' options. +

	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:	+I compiled MPlayer with libcss/libdivxdecore support, but when +I try to start it, it says: +`> error while loading shared libraries: libcss.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:	+What are you doing on Linux? Can't you install a library? Why do +we get these questions? It's not MPlayer specific at all! Add +/usr/local/lib to /etc/ld.so.conf and run ldconfig . +Or install it to /usr/lib , because if you can't solve the /usr/local +problem, you are careless enough to do such things. +

5.2. General questions +

	Q:	+What about DVD playing ? +
	A:	+Read the CD/DVD section . +

	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 RTFM) works for you. +It's much faster. If SDL's DGA works too, use that, it'll be EVEN faster! +

	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:	+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:	+Are there any mailing lists on MPlayer? +
	A:	+Yes! See RTFM 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 Appendix C. +

	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:	+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:	+LIRC doesn't work, because ... +
	A:	+Are you sure you use "mplayer_lirc" instead of "mplayer"? +

	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, +use -double option. +

	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 alpha 47 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 DivX4 +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? +

	Q:	+But configure tells me "Checking for libavcodec ... no"! +
	A:	+You need to get libavcodec from FFmpeg's CVS. Read the instructions in +the ffmpeg section. +

+5.3. File playing problems +

	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:	+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:	+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:	+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). +Maybe use the SDL driver, with -ao:sdl +

	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.. +
	A:	+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 etc/ +

	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. +If you want to use arts sound, specify audio output via 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 plays with grey screen with -vc odivx, and green with -vc divx4 . +
	A:	+It's not a DivX file, but an M$ MPEG4v3 . Update your codecs.conf. +

+5.4. Video/audio driver problems (vo/ao) +

	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:	+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 support 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:	+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 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. +

+5.5. Feature requests +

	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. +
