Feel free to add your questions/answers here, and include important error messages.

Please try to get the latest version of mplayer. a lot of the times, a problem is fixed already. problems sometimes occur when the file you are playing is newer than your mplayer version :)

==MPlayer information==
;Where is mplayer's config?

:*usually in ~/.mplayer/config
:*on windows its in the mplayer directory where mplayer.exe is. for example c:\mplayer\mplayer.exe the config is c:\mplayer\mplayer\config
::*input.conf, codecs.conf, mencoder.conf and gui.conf can go there as well.
:*you can find where mplayer looks by using mplayer -v somefile

;my docs/man does not have the feature you are talking about!

:*you can find an updated manual here: http://www.mplayerhq.hu/DOCS/man/
:*updated docs here: http://www.mplayerhq.hu/DOCS/

;the video filters (-vf) can be used with mplayer and mencoder.
:currently -vf ass/-ass does not work with mencoder.

;switches can be put into the config.
:-fs becomes fs=yes or fs=1 or fs=ja (or a few more different ways to say yes/no)
:-nodouble becomes nodouble=yes

;options have the 'no' prefix, to disable defaults or configs.
:-fs/-nofs -double/-nodouble -framedrop/-noframedrop

;gmplayer will not let you change gui.conf while it is running. close gmplayer first, then change gui.conf

;when will you release the NEXT VERSION of mplayer?

:*when the svn is stable and the mplayer team gets some time to build the package.

;if you do not like using email to report bugs to mplayer-users@mplayerhq.hu mailing list, you can report bugs to http://bugzilla.mplayerhq.hu

==Questions from #mplayer channel:==

===Subtitle/OSD===

;How do i increase the subtitle font size?
;Hi, im using a Mplayer windows gui. Is there a way to make subtitles smaller? mpui its named

:*subfont-text-scale=3 in config or mplayer -subfont-text-scale 3 file

;None of the "freetype" commands in man work when I attempt to use -subfont-autoscale or -subfont-text-scale .
;It says<nowiki>:</nowiki>
:<code>unknown option on the command line</code> or
:<code>Cannot load bitmap font<nowiki>:</nowiki> /usr/share/fonts/truetype/truetype/msttcorefonts/Arial.ttf</code>
:*install freetype/truetype and recompile mplayer

;I recompiled mplayer and now it doesn't complain about -subfont-autoscale or -subfont-text-scale.
;Unfortunately, they don't do anything

:*symlink any ttf font to ~/.mplayer/subfont.ttf or
:*specify a font, mplayer -font /dir/somefont.ttf -subfont-text-scale 3 file.avi

;Is it normal that a subtitle disappear after 7 seconds, not at the end of the time specified in the subtitle file? or help! some subtitles are missing

:*try -overlapsub or -nooverlapsub

;How do i expand the "area" so that the subtitles are lower on the screen/ put the subs in the black bars?

:*mplayer -vf expand=:-100::2

;How do I view romanian subtitles?

:*-subcp cp1250
;Greek subs:
:*-subcp iso-8859-7

;How to force SSA subtitles size to constant one

:*Try ass-force-style=FontSize=<value>.

;For vobsub subtitles, is there anyway to change the font?

:*vobsubs don't have fonts, vobsub is a set of images.
:*you can convert vobsub to txt, using TOOLS/subrip.c script
:*or download your movie's subtitles from http://www.opensubtitles.org or http://www.kloofy.net for asian movies

;I want to show the time/filename over my video at all times

:*hack up a script to do something like 'create a subtitle file with the filename in it' then call mplayer -sub blah.sub file.avi . the subtitle file contains a timestamp for the whole length of the movie with the filename as a subtitle. e.g. 0 999999 moviename-dvdrip.avi
:*patch for timestamp osd http://onebithq.com/root/mplayer/cctv

;I have embedded avi subtitles, help!
:*http://xlife.zuavra.net/index.php/54/

; can i disable mkv subtitles from the command line / config file, as opposed to having to press 'v' when i start mplayer?

:*-nosub or -sid 999

===General Questions===

;Do win32 codec dll binaries work with 64bit mplayer

:*No, you have to use a 32bit mplayer binary/build

;Hi, My cpu is too slow, help!

:*for mpeg1/2 or mpeg4 try adding -nodouble or mplayer -lavdopts lowres=1 -vfm ffmpeg will use half-res decoding to speed things up as well.
:*for H264 try mplayer -lavdopts skiploopfilter=all file.mkv
:**might cause artefacts like sudden color changes, in this case try e.g. "nonref" instead of "all"

;Your computer is still too slow?

:*Try -lavdopts skipframe=nonref:skiploopfilter=all
::*This will skip many frames, but saves 50% CPU performance
:*if using -vo gl use -vo gl:yuv=2 or similar. For high FPS video (> 50 Hz) also try -vo gl:swapinterval=0 since the default limits FPS to well below monitor refresh.

;i have a 3GHz core2duo with a pci Mystique 200 (MGA 1064SG), but playing 720p h264 in vo x11 is too slow.

:*really? if your c2d mobo does not have onboard video, then use -vf scale=640:480

;Hi folks, is there a way to "tell" mplayer (not gmplayer) not to exit when a file has been played and then wait for some new input? via a fifo or whatever

:*[http://www1.mplayerhq.hu/DOCS/tech/slave.txt http://www1.mplayerhq.hu/DOCS/tech/slave.txt]
:*mplayer -slave -idle -input=/fifo

;Anyway to dump a dvd audio stream really fast?

:*mplayer -dumpaudio dvd:// -speed 90 -vc null -vo null -benchmark

;I have a corrupt file that mplayer plays, how do i get a new "clean" version of the audio?

:*mplayer file -ao pcm

;I have a widescreen lcd monitor and everything is stretched, help!

:* use -monitoraspect 16:10 or -monitorpixelaspect 1.125

;How do I set the video window to double size when running mplayer from command line? Cannot find it in man file...

:*mplayer -xy 2

;How to set video as wallpaper ?

:* mplayer -rootwin yourmovie (Only works with the x11, xv, xmga, xvidix, quartz, macosx and directx video output drivers.)
:* Gnome : gconftool-2 -s /apps/nautilus/preferences/show_desktop -t bool false (to disable background)

;Why can`t I increase the displayed image width my mplayer?
;My image is small and black border / frame around tiny video, what gives?

:*mplayer -zoom or zoom=1 in config
:*but first try setting mplayer -vo xv or vo=xv in config

;Fullscreen does not work right in a multi-monitor setup

:*try using mplayer -fstype none

;I get errors playing h264 like these
:[h264 @ 0xd96950]concealing 1840 DC, 1840 AC, 1840 MV errors or Error while decoding frame! what gives?
:*check your config and options for 'framedrop' and disable/turn it off. try also -noframedrop
:*its possible your file is incomplete, try md5sum against the original or rehash it using your torrent program.

;I want a concise comparison of the various video outputs - say, their scores on performance measures - to help choose between em.

:*different vo's are faster/slower on different pc, drivers and video cards, its almost impossible to tell whats fastest for everyone.
:*use mplayer -nosound -benchmark file -vo (vohere) to test your video output speed
:*vo's with hardware accelerated output (like xv, vidix, directx, macosx/quartz) will usually be faster than vesa, fb, gl/gl2. but not always.

;Whats the best deinterlacing filter?

:*-vf yadif with mcedeint is reccomended by mplayer and ffmpeg devels.
:*see comparison at http://guru.multimedia.cx/deinterlacing-filters/

;I want to seek in avi while they are downloading but -forceidx is too slow.

:*use mplayer -demuxer lavf to seek in broken/incomplete avi.

;This error when trying to play an audio stream
:Win32 LoadLibrary failed to load: avisynth.dll .
;Is this DLL only available from a licensed windows install?

:*the file is most likely a playlist
:*try mplayer -playlist http://blah

:*maybe also try -correct-pts

;How to play raw ac3 files?

:*mplayer -demuxer rawaudio -rawaudio format=0x2000 file.ac3

;Having adjusted the hue/contrast previously, what's an easy way to set them all back to neutral?

:* use xvattr
:* rpm packages at http://dag.wieers.com/packages/xvattr/

;I get a 'process input error' with some wmv files and mplayer plays all blocks.

:*its probably a drm protected file
:*run strings -n19 yourfile.wmv and if a url comes out, its drm.
:*if you can play the file on windows you can remove the drm using freeme2 project (other, possibly outdated tools include: fairuse4wm (FU4WM), drmcreep, automateundrm, sidda, drmdbg, drm2wmv).

;I want to play and record tv video at the same time with mencoder.
:How do I pipe mplayer/mencoder output to stdout?

:*mplayer devs reccomend using mkfifo (named pipe) instead of stdout.
:*mencoder tv:// -tv driver=v4l:width=324:height=248:outfmt=rgb24:device=/dev/video0:adevice=hw.1,0 -oac mp3lame -lameopts cbr:br=128 -flip -ovc lavc -lavcopts threads=2 -o >( tee filename.avi | mplayer -)

;How can I play movie in rar?

;How do I extract the mpeg file/s from a vcd or bin/cue files?

:*windows: vcdgear available at http://www.vcdgear.com/ (works on linux too but it's not open source)
:*linux: use vcdxrip like so vcdxrip --bin-file=blah.bin , or just vcdxrip in a writeable directory if extracting from an actual disc. vcdxrip is part of the vcdimager package

;I want to get images from videos by frame number or frame range, not by time.

:*transcode -c 0-100 will encode 100 frames starting at frame 0 up to frame 99

===Build questions/crashes===
;mplayer doesn't compile anymore since svn rXXXXX

:*Before reporting problems, please retry after a make distclean.

;Anyone know how to play mp4 files with sound? I can only see video but no audio.

:*check mplayer output for helpful messages.
:*Requested audio codec family [faad] (afm=faad) not available. Enable it at compilation.
:*your mplayer was not compiled with faad support. recompile it after installing libfaad package.

;Hi, playing a 3GP file, I get "Cannot find codec 'amr_nb' in libavcodec". How can I solve this please

:*You need OpenCORE amrnb and/or amrwb from https://sourceforge.net/projects/opencore-amr/

;Help I get this crash X11 error: BadAlloc (insufficient resources for operation)?,?% 0 0
;MPlayer interrupted by signal 6 in module vo_check_events or this error
:"X11 error: BadAccess (attempt to access private resource denied)" using an intel card
:*add Option "LinearAlloc" "8192" to xorg.conf (under Device section) and restart X

;How to setup [[XvMC]] ?

:* Get xmvc dev lib (libxvmc-dev) and compile MPlayer with --enable-xvmc
:* If the resulting mplayer executable was linked against the xvmc wrapper library libXvMCW.so, point /usr/X11R6/lib/X11/XvMCConfig (or /etc/X11/XvMCConfig or both) to your /lib/libXvMCNVIDIA.so.* (libI810XvMC.so.1, if you don't have an NVIDIA, but an intel graphics controller), for example : echo "libXvMCNVIDIA.so.1.0.9742" > /etc/X11/XvMCConfig
:* mplayer -vc ffmpeg12mc -vo xvmc yourmovie.mpeg2
:* NB : works only with mpeg2 and mpeg.

;I get this error when playing files, whats up?
<pre>
Opening audio decoder: [ffmpeg] FFmpeg/libavcodec audio decoders
Compiler did not align stack variables.
Libavcodec has been miscompiled and may be very slow or crash.
This is not a bug in libavcodec, but in the compiler.
Do not report crashes to FFmpeg developers.
</pre>
:*gcc3x mis aligns the stack, use gcc4

;mplayer saya: error opening/initializing selected video_out device and -vo x11 does not help!

:*run mplayer -vo help and see if x11 is listed
:*use a different mplayer package if its not listed
:*recompile mplayer after getting hte x11-devel or libxv or x11 header files.

;mplayer doesn't compile with live555 library

:*Do NOT use --enable-live
:*Do NOT report errors on mailing lists if you use --enable-live

;cabac.h:526: error: can't find a register in class 'GENERAL_REGS' while reloading 'asm'

:* On x86, you can't compile mplayer after configuring with --enable-debug, because cabac.h in libavcodec can't be compiled with all optimizations when debugging is turned on.
:*Three possible solutions:
:# Don't configure with enable-debug
:# Use -fomit-frame-pointer: Copy the line beginning with "cc" ending with "-c -o h264.o h264.c" (from make output immediately above the error) and add "-fomit-frame-pointer": This might affect debugging for h264.o
:# Don't compile the optimized code: Add "#undef HAVE_EBX_AVAILABLE" to libavcodec/cabac.h

===Mencoder questions===
;I try to add subtitles to my video with mencoder but nothing happens, here is my mencoder command
<pre>mencoder file.avi -sub file.srt -oac copy -ovc copy.</pre>
:*you cant use -sub or -vf with -ovc copy, try -ovc lavc instead

;Why is encoded video always at a lower bitrate than specified?

:*try using vqmin lavc option
:*it may mean that the encoder is using all possible bits to encode the video and it's not possible to go any higher

;Hi, I am looking for a way to automatically convert ogg to mp3 I must give a directory and have everything in converted is it possible to achievve such a thing with mplayer ?

:*use aconvert found in mplayer source TOOLS/aconvert .

;I'm converting some video and i get bad desynch!

:*try adding -noskip and/or -mc 0
:*also look at -vf harddup

;I want to transcode/encode a Variable Frame Rate(VFR) video stream, such as a .ASF/.WMV .

:*When converting a VFR to a Constant/Stable Frame Rate, we must provide the desired FPS target, The most appropriate one would be an average FPS of our source, we will use this cmd to find it out:
:*mencoder file.wmv -ovc copy -nosound -o /dev/null -endpos 100

:*When its done, the sum of frames and seconds duration will be printed, we divide the (Frames / Seconds), and this is our estimated average FPS, we may use it in the following cmd:
:*mencoder file.wmv -o file.avi -ovc lavc -lavcopts vbitrate=500 -oac mp3lame -lameopts cbr:br=128 -vf harddup -ofps 25

:*While "-ofps 25", Is where we input the framerate we previously calculated.
:*(You must keep harddup,ofps. Do not use: fps,noskip. You may change: ovc,oac,lavcopts,lameopts)

;I cant encode ssa subtitles with mencoder with styles?

:*-ass does not work with mencoder yet.
:*First terminal: mkfifo stream.yuv ; mplayer -vf expand=:-60::2 -ao pcm foo.avi -ass -sub subtitles.ssa -vo yuv4mpeg
:*Second terminal: mencoder -demuxer y4m stream.yuv -o bar.avi -ovc lavc -audiofile audiofile.wav -oac mp3lame -lameopts cbr:br=128
:**the stream.yuv fifo is the file mplayer default outputs -vo yuv4mpeg to, so dont change this!
:** this technique also works for encoding vobsubs

;How do i record video from my webcam?

:*mencoder tv:// -tv driver=v4l2:width=640:height=480:fps=90:device=/dev/v4l/video0 -nosound -ovc lavc -lavcopts vcodec=mjpeg -o cooking.avi

;I am trying to use mencoder to make an mp3 file into a video using a single image as the resulting video
:The duration of the audio file should be known.
: e.g. duration='''132.8''' seconds
mencoder mf://file.jpg -ovc lavc -oac copy -audiofile song.mp3 -fps 1/'''132.8''' -ofps 30 -o finished.avi

;I am trying to encode files to use with openoffice presentation and nothing works!
:cinepak works in openoffice with JMF support

===Streaming Questions===
;Help i cant access azntv.com nsv streams!

:* the server only allows winamp user agent
:* -user-agent "Winamp NSV Player/5.12 (ultravox/2.0)"

;rtsp<nowiki>://</nowiki> rm streams are soooo slow! even with -dumpstream!

:*-bandwidth 1000000

;I cant play some <nowiki>rtsp://</nowiki> mov urls. but vlc can!

:*you might be behind a firewall or router where udp does not work. try -rtsp-stream-over-tcp

;how do i play a multicast stream with mplayer?

:*first, set up your igmp profile. on linux this is done using sysctls. you have to use the proper version of igmp which your network design supports (sysctl -a | grep igmp helps)
:*second, add a routing entry to your routing table. (to expect the traffic from the proper interface (if you've got more, of course))
:*then <nowiki>mplayer udp://mcastaddress:port</nowiki> will play the stream

Sang Cho's Win32 Disassembler

2009-11-20T22:17:42Z

Sherpya: no more geocities :D

* Website: http://cyber.chongju.ac.kr/~sangcho/

Sang Cho's Win32 Disassembler is an extremely competent static binary disassembler for Windows portable executable (PE) format files (which comprise most Win32 EXE and DLL files). The code compiles on both Windows and Linux using gcc. Be advised, however, that it maybe necessary to convert carriage returns on Linux in order to get gcc to process the source files correctly.

Interesting Patches

2009-11-20T21:16:13Z

Sherpya: added new project page

This page tries to collect some useful patches for FFmpeg that didn't make into SVN for some reason or another.

== native [[Zlib]] decoder by [[User:Mans|Mans Rullgard]] ==
http://lists.mplayerhq.hu/pipermail/ffmpeg-devel/2007-July/032807.html

In the same thread, there are patches to use the native decoder in several FFmpeg decoders.

== File concatenation by Wolfram Gloger ==
http://lists.mplayerhq.hu/pipermail/ffmpeg-devel/2007-July/032121.html

== "mem" file protocol by Lagrange Multiplier ==
The "mem" protocol simply uses RAM as a source for input multimedia data, akin to how the "file" and "pipe" protocols use filesystem files and pipes as sources.

http://lists.mplayerhq.hu/pipermail/ffmpeg-devel/2007-May/028489.html

== Presets/profiles for usual targets by Panagiotis Issaris ==
Allow to keep in a text file groups of command options, and apply them at once by specifying the target name.

Handy for iPod, PSP, or any other picky multimedia player that otherwise requires lengthy command lines.

http://article.gmane.org/gmane.comp.video.ffmpeg.devel/37244

== [[AMV]] encoder ==
http://code.google.com/p/amv-codec-tools/

See this post [http://lists.mplayerhq.hu/pipermail/ffmpeg-devel/2007-October/037356.html] to see what is missing to get it into SVN.

Note: An updated patch is under development by [[User:DrV]] based on an updated patch by the original [[User:Suxen drol|author]].

== G722 decoder by Chas Williams ==
http://lists.mplayerhq.hu/pipermail/ffmpeg-devel/2009-April/067552.html

This patch has no licensing issues, but also contains an encoder which was basically rejected by the project maintainer.

It might be enough to resend the decoder alone to get it into svn.

FluxDVD

2009-01-13T14:12:42Z

Sherpya:

* Extensions: .fluxdvd
* FOURCCs: ?
* Company: http://www.fluxdvd.com
* Originally developed by: Danish Aarhus University
* Information: http://www.fluxdvd.com/info.html
* Samples: (in /incoming/)

'''fluxDVD''' is a is a highly compressed file type, containing all the contents of a DVD-Video movie, the format is commercial, patented, closed source and proprietary. It is currently available only for the Microsoft Windows operating-system. The ratDVD program (transcoder and GUI) works by compressing a full DVD-Video into a .ratDVD file and then playing its contents by decompressing the file and using a [[Microsoft DirectShow API|DirectShow]]-compatible DVD-Video player, (including DVD-Video all features like like navigation, multiple audio and subtitle tracks, video angles, seamless branching, etc.). The .fluxdvd movie files compressed by ratDVD are usually one to two GigaByte in size. If the [[DRM]] ([[Recordable CSS]]) license permits, you can uncompress/burn a fluxDVD to DVD-R to get a 100% compatible DVD-Video that plays in every hardware or software DVD-Video player.

fluxDVD was previously available for free under the name ratDVD, (also closed source and proprietary), ratDVD developed by the Danish Aarhus University was kind of a preview version of the now commercially sold fluxDVD. While ratDVD contained the features that allowed the home user to create their own archived DVDs, this function has been removed from fluxDVD, allowing only content owners to make and sell fluxDVD archives. Unlike ratDVD which acording to their authors used a homebrew video codec, [[fluxDVD]] uses a video codec variant based on the [[H.264]] standard.

==Video codec==
Video codec variant based on the [[H.264]] standard.

==Audio Codec==
Standard Dolby Digital [[A52|AC-3]] audio format.

==Container==
ratDVD uses a [[ZIP]] based container format, containing all the contents of a DVD-Video movie. The .fluxdvdDVD files are usually one to two gigabytes in size. Additionally a fluxDVD can contain tagging, cover and label data to enable you to create a cover for the DVD-Video movie.

Sherpya:

* FOURCCs: MSUD
* Website: http://www.compression.ru/video/ls-codec/index_en.html
* Samples: http://samples.mplayerhq.hu/V-codecs/msud/

MSU Lossless Video Codec is a lossless video compressor for [[Microsoft Audio/Video Interleaved|AVI]] files
written by Dmitry Vatolin, Dmitry Popov and Sergey Putilin.
The codec is free for non-commercial use.
The authors claim the codec gives the highest compression ratio in the lossless video compression field.
The results are very interesting, you can see codecs comparison on the web site.
If the source colorspace is RGB, you can opt for YUV conversion to achieve better results.
Integrated denoising algorithms can help improving further the compression ratio.
The codec also supports interlaced input.
