Feel free to add your questions/answers here, and include important error messages. or if you don't have an account, ask projects@mplayerhq.hu to update this page.

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.
:-ass works with mencoder, but its somewhat tricky to use.
:this seems only to work with external subs (extract your subs first!) mencoder d:\SAMPLE.AVI -sub test_02.ass -vf fixpts=fps=24000/1001,ass,fixpts -ass -nosound -ovc lavc -o out.avi

;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://web.archive.org/web/20080517095711/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

; hey all. I have some movies that are 3d sbs, and I want subtitles to appear on both halves (possibly in the same position)

:*use this tool to convert a sub to a 3d sub http://code.google.com/p/sub3dtool/

; I want to watch two subtitles at the same time
:*use this script to merge the subtitles: http://yuenhoe.com/blog/2013/04/playing-multiple-subtitles-simultaneously-with-mplayer/

===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
:*vdpau is fastest for nvidia, vaapi is fastest for intel and amd. the non gpu accelerated outputs like xv, gl, gl2, vidix, directx, macosx/quartz will usually be faster than vesa, fb, and mga.

;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
:*also try wget it to make sure its audio and not some html page.

:*use -demuxer lavf if you dont have mplayer compiled with libtheora
:*maybe also try -correct-pts

;How to play raw ac3 files?

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

:* 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).

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

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

;how do i compile an older version of mplayer? it always checks out fresh copies of libavcodec!

:*svn up --ignore-externals -r {2009-12-31} . libavutil libavcodec libavformat libpostproc libdvdread4 libdvdnav

;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>
:*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)

;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

some complaints/known bugs about mplayer and mencoder

*-oac mp3lame -lameopts abr/vbr causes desync in videos

*-dumpstream and -endpos or -frames dont work together

*cant save/encode video and play at the same time with one mplayer/mencoder instance

*playlists require -playlist switch (mplayer should detect playlists!)

*cant edit gui.conf while gmplayer is running

*opening multiple files causes multiple gmplayer/mplayer instancess

*-cache affects -ss accuracy

==Capture cards and Webcam command lines==
MPlayer can be hard to use for devices, its not very userfriendly in automatically guessing working options. below is an incomplete list of working lines for specified hardware. if you use mplayer with a webcam and it requires some odd options, please list it here.

Category talk:Video FourCCs

2013-10-04T01:18:20Z

Compn: yet another lossless video codec

Some FourCCs are only 3 printing characters. How is the 4th byte repesnted because FourCC is a 4 byte binary string? Is it a space as first or last byte or 0x00?

: generally, a space (ASCII 0x20) completes the FourCC; I will clarify --[[User:Multimedia Mike|Multimedia Mike]] 12:28, 11 June 2006 (EDT)

I found great codec list: http://kmkz.jp/key/codecs/codecs.xml . Those data seems to be auto-collected from Kamikaze Media Player users. --[[User:Nazo|Nazo]] 03:39, 8 January 2009 (EST)

==vfw codec list==

*If you need help finding any of these codecs let me know - compn@ffmpeg.org

todo:
figure how to encode with acm codecs easily
cleanup list
remove duplicate entries (keep different dll names (useful for searching/testing)
download each new codec, see if it supports encoding (and with vfw 1.0 too)

todo: install all of these: http://www.drakan.ru/FTProot/vid_work/codecs/ and try encoding with all codecs.

ones with -'s mean that they are in mplayer.

RealMedia

2013-09-25T12:16:42Z

Compn: /* Video */

* Extensions: rm, ra, rmvb
* Company: [[Real]]
* Specifications: https://common.helixcommunity.org/2003/HCS_SDK_r5/htmfiles/rmff.htm

Multimedia container format developed by [[Real]] and used almost exclusively for codecs developed by [[Real]].

The old .ra files are just for audio. The newer RealMedia (.rm) files are for audio and video.

== RA Format ==

This is the old audio-only RealAudio file format.
A very similar structure is also used to describe audio streams in RM files.

The audio data part is just a stream of bytes with no structure.
There is no index in .ra files, but seeking is possible because the codecs are CBR.

=== RealAudio 1.0 file (.ra version 3) ===

This is from the very first version of RealAudio (1995). These files can only contain [[RealAudio 14.4|8kbps VSELP]] audio data. A [[FourCC]] (lpcJ) may be present, but it is ignored. Byte order is big-endian.

byte[4] Header signature ('.', 'r', 'a', 0xfd)
word Version (always 3)
word Header size, not including first 8 bytes
byte[10] Unknown
dword Data size
byte Title string length
byte[] Title string
byte Author string length
byte[] Author string
byte Copyright string length
byte[] Copyright string
byte Comment string length
byte[] Comment string
byte Unknown *
byte Fourcc string length (always 4) *
byte[] Fourcc string (always "lpcJ") *
Audio data

Notes:
* Fields marked with * may be missing. Based on the only known sample with no [[FourCC]], it's assumed that all these fields are either present or missing. To determine if they are missing, check the header size (bytes 6-7).
* The informative fields (title, author, copyright and comment) can have zero length.

=== RealAudio 2.0 file (.ra version 4) ===

This is second version of the RealAudio file format. It is distinguished from the above by the value in byte 5 (=0x04). This type of file must contain a valid [[FourCC]] to identify the audio codec.

Possible [[FourCC]] values are [[RealAudio 28.8|28_8]], [[RealAudio_dnet|dnet]] and [[RealAudio_sipr|sipr]].

byte[4] Header signature ('.', 'r', 'a', 0xfd)
word Version (always 4)
word Unused (always 0)
byte[4] ra4 signature (always ".ra4")
dword Data size - 0x27
word Version2 (always equal to version)
dword Header size - 16
word Codec flavor
dword Coded frame size
byte[12] Unknown
word Sub packet h
word Frame size
word Subpacket size
word Unknown
word Samplerate
word Unknown
word Sample size
word Channels
byte Interleaver ID string length (always 4)
byte[] Interleaver ID string
byte [[FourCC]] string length (always 4)
byte[] [[FourCC]] string
byte[3] Unknown
byte Title string length
byte[] Title string
byte Author string length
byte[] Author string
byte Copyright string length
byte[] Copyright string
byte Comment string length
byte[] Comment string
Audio Data

Notes:
* The 0x27 in data size is the size of the fixed-length part of the header (up to channels).
* The informative fields (title, author, copyright and comment) can have zero length.

=== .ra version 5 ===

While the .ra header can contain version 5, there are no known RealAudio files with this format, and it's not known if they really exist.

== RealMedia Format ==

This is the newer format which stores both audio and video. All multi-byte numbers are stored in big-endian format.

A RealMedia file consists of a series of chunks. Each chunk has the following format:

dword chunk type ([[FOURCC]])
dword chunk size, including 8-byte preamble
word chunk version
byte[] chunk payload

Real chunk types:
* .RMF: RealMedia file header (only one per file, must be the first chunk)
* PROP: File properties (only one per file)
* MDPR: Stream properties (one for each stream)
* CONT: Content description/metadata (typically one per file)
* DATA: File data
* INDX: File index (typically one per stream)

=== RealMedia file header (.RMF) ===

This must be the first chunk in a RealMedia file. Only one .RMF can be present in a file. The only useful information carried by .RMF is the number of headers.

A .RMF chunk has the following format

dword chunk type ('.RMF')
dword chunk size (typically 0x12)
word chunk version (always 0, for every known file)
dword file version
dword number of headers

Notes:
* All known sample files have version equal to 0.
* There is a sample with chunk size = 0x10, in that case file version is a word. Note that the sample has chunk version = 0 like all other files.

=== File properties header (PROP) ===

This chunk contains some information about the general properties of a RealMedia file. Only one PROP chunk can be present in a file.

A PROP chunk has the following format

dword Chunk type ('PROP')
dword Chunk size (typically 0x32)
word Chunk version (always 0, for every known file)
dword Maximum bit rate
dword Average bit rate
dword Size of largest data packet
dword Average size of data packet
dword Number of data packets in the file
dword File duration in ms
dword Suggested number of ms to buffer before starting playback
dword Offset of the first INDX chunk form the start of the file
dword Offset of the first DATA chunk form the start of the file
word Number of streams in the file
word Flags (bitfield, see below)

Flags:
* bit 0: file can be saved on disk
* bit 1: PerfectPlay can be used (extra buffering)
* bit 2: the file is a live broadcast

=== Media properties header (MDPR) ===

This chunk contains information about the properties of a RealMedia stream. This header defines the type of a stream and the codec used. All codec-related data is in the type specific part of this header.

Many fields share the same meanings as the ones in PROP chunk, but in this case they are specific for one stream.

There is one MDPR chunk for every stream in the file.

A MDPR chunk has the following format

dword Chunk type ('MDPR')
dword Chunk size
word Chunk version (always 0, for every known file)
word Stream number
dword Maximum bit rate
dword Average bit rate
dword Size of largest data packet
dword Average size of data packet
dword Stream start offset in ms
dword Preroll in ms (to be subtracted from timestamps?)
dword Stream duration in ms
byte Size of stream description string
byte[] Stream description string
byte Size of stream mime type string
byte[] Mime type string
dword Size of type specific part of the header
byte[] Type specific data, meaning and format depends on mime type

==== Audio (audio/) ====

===== audio/x-pn-realaudio and audio/x-pn-multirate-realaudio =====
These mimetypes are used to specify streams with RealAudio codecs. There are 3 known versions of this datablock: ra3, ra4, ra5. ra3 is used only with the old 14_4 codec, ra4 and ra5 can be used with all the other codecs.

The audio block has this format

byte[4] Header signature ('.', 'r', 'a', 0xfd)
word Version (3, 4 or 5)
#if version == 3
word Header size, not including first 8 bytes
byte[10] Unknown
dword Data size
byte Title string length
byte[] Title string
byte Author string length
byte[] Author string
byte Copyright string length
byte[] Copyright string
byte Comment string length
byte[] Comment string
byte Unknown *
byte Fourcc string length (always 4) *
byte[] Fourcc string (always "lpcJ") *
#elseif version == 4 or version == 5
word Unused (always 0)
byte[4] ra signature (".ra4" or ".ra5", depending on version)
dword Unknown (maybe data size)
word Version2 (always equal to version)
dword Header size
word Codec flavor
dword Coded frame size
byte[12] Unknown
word Sub packet h
word Frame size
word Subpacket size
word Unknown
#if version == 5
byte[6] Unknown
#endif
word Samplerate
word Unknown
word Sample size
word Channels
#if version == 4
byte Interleaver ID string length (always 4)
byte[] Interleaver ID string
byte [[FourCC]] string length (always 4)
byte[] [[FourCC]] string
#endif
#if version == 5
dword Interleaver ID
dword [[FourCC]]
#endif
byte[3] Unknown
#if version == 5
byte Unknown
#endif
dword Codec extradata length
byte[] Codec extradata
#endif

===== audio/X-MP3-draft-00 =====
This is used to store MP3 audio in rm container.
When this mimetype is used the type-specific part of the MDPR header is not used, and its length is set to 0.

The MP3 frames are stored in ADU format (see RFC 3119 for details) with no interleaving (at least this is true in the only known sample).

===== audio/x-ralf-mpeg4 =====
This is used to store [[Real Lossless Codec|ralf]] lossless audio. This is the only known RealAudio codec that does not use the x-pn-realaudio mimetype.

The format of this type-specific data is not known.

=== Content description header (CONT) ===

This chunk contains some text information (like title, author, ...) about the content of the file. This header has an informative purpose only and it's not needed to demux the file.

A CONT chunk has the following format

dword Chunk type ('CONT')
dword Chunk size
word Chunk version (always 0, for every known file)
word Title string length
byte[] Title string
word Author string length
byte[] Author string
word Copyright string length
byte[] Copyright string
word Comment string length
byte[] Comment string

=== Data header (DATA) ===

This chunk contains a group of data packets. Packets from each stream are interleaved, except for multirate files.

A DATA chunk has the following format

dword Chunk type ('DATA')
dword Chunk size
word Chunk version (always 0, for every known file)
dword Number of data packets in this chunk
dword Offset of the next DATA chunk (form the start of the file)
byte[] Data packets

Each data packet has this format

word Packet version (0 or 1 in available samples)
word Packet size
word Stream number
dword Timestamp (in ms)
byte Unknown
byte Flags (bitfield, see below)
#if version == 1
byte Unknown
#endif
byte[] Stream-specific data

Flags:
* bit 0: reliable packet (refers to network transmission method)
* bit 1: keyframe

Note:
The previous description of the data packet comes from working demuxer code, the description in official [[Real]] docs (somewhere on [[Helix]] site) is a bit different:

word Packet version
word Packet size
word Stream number
dword Timestamp
#if version == 0
byte Packet group
byte Flags
#endif
#if version == 1
word ASM rule
byte ASM flags
#endif
byte[] Stream-specific data

where packet group is "The packet group to which the packet belongs. If packet grouping is not used, set this field to 0 (zero)", asm rule is "The ASM rule assigned to this packet" and asm flags "Contains HX_ flags that dictate stream switching points".

=== Index header (INDX) ===

This chunk contains index entries. It comes after all the DATA chunks.
An index chunk contains data for a single stream, A file can have more than one INDX chunk.

A INDX chunk has the following format

dword Chunk type ('INDX')
dword Chunk size
word Chunk version (always 0, for every known file)
dword Number of entries in this chunk
word Stream number
dword Offset of the next INDX chunk (form the start of the file)
byte[] Index entries

Each index entry has this format

word Entry version (always 0, for every known file)
dword Timestamp (in ms)
dword Packet offset in file (form the start of the file)
dword Packet number

== Codecs ==

Codecs in RealMedia are identified by the following four character codes:

===== Audio =====

* [[RealAudio 14.4|lpcJ]] - RealAudio 1.0 (VSELP)
* [[RealAudio 28.8|28_8]] - RealAudio 2.0 (LD-CELP)

=== File properties header (PROP) ===

This chunk contains some information about the general properties of a RealMedia file. Only one PROP chunk can be present in a file.

A PROP chunk has the following format

dword Chunk type ('PROP')
dword Chunk size (typically 0x32)
word Chunk version (always 0, for every known file)
dword Maximum bit rate
dword Average bit rate
dword Size of largest data packet
dword Average size of data packet
dword Number of data packets in the file
dword File duration in ms
dword Suggested number of ms to buffer before starting playback
dword Offset of the first INDX chunk form the start of the file
dword Offset of the first DATA chunk form the start of the file
word Number of streams in the file
word Flags (bitfield, see below)

Flags:
* bit 0: file can be saved on disk
* bit 1: PerfectPlay can be used (extra buffering)
* bit 2: the file is a live broadcast

=== Media properties header (MDPR) ===

This chunk contains information about the properties of a RealMedia stream. This header defines the type of a stream and the codec used. All codec-related data is in the type specific part of this header.

Many fields share the same meanings as the ones in PROP chunk, but in this case they are specific for one stream.

There is one MDPR chunk for every stream in the file.

A MDPR chunk has the following format

dword Chunk type ('MDPR')
dword Chunk size
word Chunk version (always 0, for every known file)
word Stream number
dword Maximum bit rate
dword Average bit rate
dword Size of largest data packet
dword Average size of data packet
dword Stream start offset in ms
dword Preroll in ms (to be subtracted from timestamps?)
dword Stream duration in ms
byte Size of stream description string
byte[] Stream description string
byte Size of stream mime type string
byte[] Mime type string
dword Size of type specific part of the header
byte[] Type specific data, meaning and format depends on mime type

==== Audio (audio/) ====

===== audio/x-pn-realaudio and audio/x-pn-multirate-realaudio =====
These mimetypes are used to specify streams with RealAudio codecs. There are 3 known versions of this datablock: ra3, ra4, ra5. ra3 is used only with the old 14_4 codec, ra4 and ra5 can be used with all the other codecs.

The audio block has this format

byte[4] Header signature ('.', 'r', 'a', 0xfd)
word Version (3, 4 or 5)
#if version == 3
word Header size, not including first 8 bytes
byte[10] Unknown
dword Data size
byte Title string length
byte[] Title string
byte Author string length
byte[] Author string
byte Copyright string length
byte[] Copyright string
byte Comment string length
byte[] Comment string
byte Unknown *
byte Fourcc string length (always 4) *
byte[] Fourcc string (always "lpcJ") *
#elseif version == 4 or version == 5
word Unused (always 0)
byte[4] ra signature (".ra4" or ".ra5", depending on version)
dword Unknown (maybe data size)
word Version2 (always equal to version)
dword Header size
word Codec flavor
dword Coded frame size
byte[12] Unknown
word Sub packet h
word Frame size
word Subpacket size
word Unknown
#if version == 5
byte[6] Unknown
#endif
word Samplerate
word Unknown
word Sample size
word Channels
#if version == 4
byte Interleaver ID string length (always 4)
byte[] Interleaver ID string
byte [[FourCC]] string length (always 4)
byte[] [[FourCC]] string
#endif
#if version == 5
dword Interleaver ID
dword [[FourCC]]
#endif
byte[3] Unknown
#if version == 5
byte Unknown
#endif
dword Codec extradata length
byte[] Codec extradata
#endif

===== audio/X-MP3-draft-00 =====
This is used to store MP3 audio in rm container.
When this mimetype is used the type-specific part of the MDPR header is not used, and its length is set to 0.

The MP3 frames are stored in ADU format (see RFC 3119 for details) with no interleaving (at least this is true in the only known sample).

===== audio/x-ralf-mpeg4 =====
This is used to store [[Real Lossless Codec|ralf]] lossless audio. This is the only known RealAudio codec that does not use the x-pn-realaudio mimetype.

The format of this type-specific data is not known.

=== Content description header (CONT) ===

This chunk contains some text information (like title, author, ...) about the content of the file. This header has an informative purpose only and it's not needed to demux the file.

A CONT chunk has the following format

dword Chunk type ('CONT')
dword Chunk size
word Chunk version (always 0, for every known file)
word Title string length
byte[] Title string
word Author string length
byte[] Author string
word Copyright string length
byte[] Copyright string
word Comment string length
byte[] Comment string

=== Data header (DATA) ===

This chunk contains a group of data packets. Packets from each stream are interleaved, except for multirate files.

A DATA chunk has the following format

dword Chunk type ('DATA')
dword Chunk size
word Chunk version (always 0, for every known file)
dword Number of data packets in this chunk
dword Offset of the next DATA chunk (form the start of the file)
byte[] Data packets

Each data packet has this format

word Packet version (0 or 1 in available samples)
word Packet size
word Stream number
dword Timestamp (in ms)
byte Unknown
byte Flags (bitfield, see below)
#if version == 1
byte Unknown
#endif
byte[] Stream-specific data

Flags:
* bit 0: reliable packet (refers to network transmission method)
* bit 1: keyframe

Note:
The previous description of the data packet comes from working demuxer code, the description in official [[Real]] docs (somewhere on [[Helix]] site) is a bit different:

word Packet version
word Packet size
word Stream number
dword Timestamp
#if version == 0
byte Packet group
byte Flags
#endif
#if version == 1
word ASM rule
byte ASM flags
#endif
byte[] Stream-specific data

where packet group is "The packet group to which the packet belongs. If packet grouping is not used, set this field to 0 (zero)", asm rule is "The ASM rule assigned to this packet" and asm flags "Contains HX_ flags that dictate stream switching points".

=== Index header (INDX) ===

This chunk contains index entries. It comes after all the DATA chunks.
An index chunk contains data for a single stream, A file can have more than one INDX chunk.

A INDX chunk has the following format

dword Chunk type ('INDX')
dword Chunk size
word Chunk version (always 0, for every known file)
dword Number of entries in this chunk
word Stream number
dword Offset of the next INDX chunk (form the start of the file)
byte[] Index entries

Each index entry has this format

word Entry version (always 0, for every known file)
dword Timestamp (in ms)
dword Packet offset in file (form the start of the file)
dword Packet number

== Codecs ==

Codecs in RealMedia are identified by the following four character codes:

===== Audio =====

* [[RealAudio 14.4|lpcJ]] - RealAudio 1.0 (VSELP)
* [[RealAudio 28.8|28_8]] - RealAudio 2.0 (LD-CELP)
* [[RealAudio_dnet|dnet]] - AC3
* [[RealAudio_sipr|sipr]] - Sipro
* [[RealAudio_cook|cook]] - Cook

* [[Real Lossless Codec|ralf]] - RealAudio Lossless Format
* [[RealAudio_raac|raac]] - LC-AAC
* [[RealAudio_racp|racp]] - HE-AAC

===== Video =====

* [[RealVideo|RV10]] - H.263
* [[RealVideo|RV13]] - H.263
* [[RealVideo G2|RV20]] - H.263+
* [[RealVideo 3|RV30]] - H.264 precursor

Compn: /* Subtitle/OSD */

This page will attempt to list all of the frequent questions we get in the #mplayer irc channel on irc.freenode.net.

Official MPlayer Frequently asked Questions:
http://www.mplayerhq.hu/DOCS/HTML/en/faq.html

MPlayer Wikibooks:
http://en.wikibooks.org/wiki/Mplayer

Feel free to add your questions/answers here, and include important error messages. or if you don't have an account, ask projects@mplayerhq.hu to update this page.

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.
:-ass works with mencoder, but its somewhat tricky to use.
:this seems only to work with external subs (extract your subs first!) mencoder d:\SAMPLE.AVI -sub test_02.ass -vf fixpts=fps=24000/1001,ass,fixpts -ass -nosound -ovc lavc -o out.avi

;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

; hey all. I have some movies that are 3d sbs, and I want subtitles to appear on both halves (possibly in the same position)

:*use this tool to convert a sub to a 3d sub http://code.google.com/p/sub3dtool/

===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?

;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
:*vdpau is fastest for nvidia, vaapi is fastest for intel and amd. the non gpu accelerated outputs like xv, gl, gl2, vidix, directx, macosx/quartz will usually be faster than vesa, fb, and mga.

;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
:*also try wget it to make sure its audio and not some html page.

;I want to play a DVD that's already on my hard drive with gmplayer.

this program is highly recommended, it uses ffmpeg and mplayer: http://moviethumbnail.sourceforge.net/

:*mplayer -vo jpeg -sstep 30 -frames 10 yourfile
:*add -vf scale=320:240 if you want smaller image size...
:*use -vf framestep if sstep does not work on your source.
:** also check out this howto for using ffmpeg or mencoder to create movies http://electron.mit.edu/~gsteele/ffmpeg/

:*use -demuxer lavf if you dont have mplayer compiled with libtheora
:*maybe also try -correct-pts

;How to play raw ac3 files?

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

;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)

;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
:mencoder input.avi -ovc vfw -xvfwopts codec=iccvid.dll -oac pcm -o out.avi

===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

MPlayer FAQ

2013-07-07T20:58:34Z

Compn: /* Subtitle/OSD */ 3d subs

This page will attempt to list all of the frequent questions we get in the #mplayer irc channel on irc.freenode.net.

Official MPlayer Frequently asked Questions:
http://www.mplayerhq.hu/DOCS/HTML/en/faq.html

MPlayer Wikibooks:
http://en.wikibooks.org/wiki/Mplayer

Feel free to add your questions/answers here, and include important error messages. or if you don't have an account, ask projects@mplayerhq.hu to update this page.

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.
:-ass works with mencoder, but its somewhat tricky to use.
:this seems only to work with external subs (extract your subs first!) mencoder d:\SAMPLE.AVI -sub test_02.ass -vf fixpts=fps=24000/1001,ass,fixpts -ass -nosound -ovc lavc -o out.avi

;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

; hey all. I have some movies that are 3d sbs, and I want subtitles to appear on both halves (possibly in the same position)
:*use this tool to convert a sub to a 3d sub http://code.google.com/p/sub3dtool/

===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
:*vdpau is fastest for nvidia, vaapi is fastest for intel and amd. the non gpu accelerated outputs like xv, gl, gl2, vidix, directx, macosx/quartz will usually be faster than vesa, fb, and mga.

;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
:*also try wget it to make sure its audio and not some html page.

;I want to play a DVD that's already on my hard drive with gmplayer.

:*gmplayer dvd:// -dvd-device /dir/vobfiless/

;How do i position mplayer window?
;How do i make mplayer start in the same spot every time?

:*see -geometry

;How do i extract frames from videos?
;How do i make thumbnails from videos?
;How do i make a gallery of images from a movie?

this program is highly recommended, it uses ffmpeg and mplayer: http://moviethumbnail.sourceforge.net/

:*mplayer -vo jpeg -sstep 30 -frames 10 yourfile
:*add -vf scale=320:240 if you want smaller image size...
:*use -vf framestep if sstep does not work on your source.
:** also check out this howto for using ffmpeg or mencoder to create movies http://electron.mit.edu/~gsteele/ffmpeg/

;I use mencoder to create videos from jpg files in a directory.
;The problem is the files are 1-out.jpg 2-out.jpg ... mencoder gets the order wrong.

:*try wtih mf://%d-out.jpg

;I'm having trouble viewing the Guadec 2006 talks, in Ogg Theora format, in mplayer.
;Anyone try these before? My error seems to be

:*use -demuxer lavf if you dont have mplayer compiled with libtheora
:*maybe also try -correct-pts

;How to play raw ac3 files?

:*mplayer -demuxer rawaudio -rawaudio format=0x2000 file.ac3
:*format=0x2001 for dts
:*check codecs.conf for format= entries

;All my files with AC3 audio are too quiet! I cant hear anything! How do i make it louder?

:*try mplayer -demuxer lavf file
:*make sure mplayer and the other program are using the same audio and video output
:*make sure the other program is not locking the audio/video output (by closing other multimedia programs first (also make sure artsd is not locking /dev/dsp (use lsof | grep -i dsp)))
:*if xine plays the file ok, but mplayer stutters, try mplayer -autosync 30 file

;How do i change mplayer speed but keep pitch the same?

:*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?

:*unrar p -inul movie.part01.rar |mplayer -noidx -

;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

;How do I play a vcd .bin file with mplayer? i cant get sound to work.

:*mplayer BSVCD.BIN -demuxer lavf -lavfdopts format=mpeg -aid 1

;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

;How do i dump Closed Captioned ( mpeg-ts cc ) in real time from my atsc qam tuner?

:cat /dev/dvb/adapter0/dvr0 | tee pipe1 > pipe2 | paste pipe1 > $(date+%F_%H%m)-CBS-HD-cat.mpeg | zvbi-atsc-cc --atsc -e ~/.azap/channels.conf -m -c CBS-HD -T < pipe2

;I cant access a web radio stream due to firewall or i want to listen to a radio station on my phone

:*http://www.yourmuze.fm/ can do it for you.

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

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

;how do i compile an older version of mplayer? it always checks out fresh copies of libavcodec!

:*svn up --ignore-externals -r {2009-12-31} . libavutil libavcodec libavformat libpostproc libdvdread4 libdvdnav

;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)

;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
:mencoder input.avi -ovc vfw -xvfwopts codec=iccvid.dll -oac pcm -o out.avi

===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

==Encoding to PSP/iPod/Other Devices==

==Complaints/Known Bugs==
some complaints/known bugs about mplayer and mencoder

*-oac mp3lame -lameopts abr/vbr causes desync in videos

*-dumpstream and -endpos or -frames dont work together

*cant save/encode video and play at the same time with one mplayer/mencoder instance

*playlists require -playlist switch (mplayer should detect playlists!)

*cant edit gui.conf while gmplayer is running

*opening multiple files causes multiple gmplayer/mplayer instancess

*-cache affects -ss accuracy

==Capture cards and Webcam command lines==
MPlayer can be hard to use for devices, its not very userfriendly in automatically guessing working options. below is an incomplete list of working lines for specified hardware. if you use mplayer with a webcam and it requires some odd options, please list it here.

*3com Homeconnect USB webcam (on windows) : mplayer tv:// -fps 30 -tv driver=dshow:outfmt=bgr32 -vf flip
