Yes, this is the MPlayer FAQ.
|
|
=============================
|
|
|
|
About:
|
|
~~~~~~
|
|
Many people asked same questions so I decided to write this stuff.
|
|
I know that people will never read this but at least i try to
|
|
pull down number of these mails.
|
|
And from now i can say that "read the fuckin' FAQ!" :-)
|
|
|
|
Let's ask!
|
|
~~~~~~~~~~
|
|
Q: What about DVD playback?
|
|
A: Read files 'DVD' and 'DVD-FAQ'.
|
|
|
|
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 DOCS/inttypes.h to MPlayer directory (cp DOCS/inttypes.h .)
|
|
try again... if fail, contact me
|
|
|
|
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? (it's 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 -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
|
|
...
|
|
A: See the previous answer.
|
|
|
|
Q: I've downloaded an ASF with asfrecorder, but MPlayer can't play it !
|
|
A: asfrecorder, and the ASF format itself is a big crap.
|
|
Do not contact us, go to hell.
|
|
|
|
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 WindowMaker and fullscreen xv/xmga/sdl/x11 modes..
|
|
It was OK before the ICCCM-compliance patch.
|
|
A: Known problem, ICCCM sucks.
|
|
|
|
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 !!! **
|
