Description
mplayer is a movie player for LINUX (runs on many other Unices and non-x86 CPUs, see the documentation). It plays most MPEG/:VOB, AVI, ASF/:WMA/:WMV, RM, QT/:MOV/:MP4, OGG/:OGM, VIVO, FLI, NuppelVideo, yuv4mpeg, FILM and RoQ files, supported by many native, XAnim, and Win32 DLL codecs. You can watch VideoCD, SVCD, DVD, 3ivx, DivX 3/:4/:5 and even WMV movies, too (without using the avifile library).

Another great feature of MPlayer is the wide range of supported output drivers. It works with X11, XV, DGA, OpenGL, SVGAlib, fbdev, AAlib, DirectFB, but you can also use GGI, SDL (and this way all their drivers), VESA (on every VESA compatible card, even without X11), some low level card-specific drivers (for Matrox, 3Dfx and ATI) and some hardware MPEG decoder boards, such as the Siemens DVB, DXR2 and DXR3/:Hollywood+. Most of them support software or hardware scaling, so you can enjoy movies in fullscreen.

MPlayer has an onscreen display (OSD) for status information, nice big antialiased shaded subtitles and visual feedback for keyboard controls. European/:ISO 8859-1,2 (Hungarian, English, Czech, etc), Cyrillic and Korean fonts are supported along with 10 subtitle formats (MicroDVD, SubRip, SubViewer, Sami, VPlayer, RT, SSA, AQTitle, JACOsub and our own: MPsub) and DVD subtitles (SPU streams, VobSub and Closed Captions).

mencoder (MPlayer's Movie Encoder) is a simple movie encoder, designed to encode MPlayer-playable movies (see above) to other MPlayer-playable formats (see below). It encodes to DivX4, XviD, one of the libavcodec codecs and PCM/:MP3/:VBRMP3 audio in 1, 2 or 3 passes. Furthermore it has stream copying abilities, a powerful plugin system (crop, expand, flip, postprocess, rotate, scale, noise, rgb/:yuv conversion) and more.

gmplayer is MPlayer with a graphical user interface. It has the same options as MPlayer.

General Notes
Also see the HTML documentation!

Every 'flag' option has a 'noflag' counterpart, e.g. the opposite of the -fs option is -nofs.

You can put all of the options in a configuration file which will be read every time mplayer is run. The system-wide configuration file 'mplayer.conf' is in your configuration directory (e.g. /etc/:mplayer or /usr/:local/:etc/:mplayer), the user specific one is '~/:.mplayer/:config'. User specific options override system-wide options and options given on the command line override either. The syntax of the configuration files is 'option=<value>', everything after a '#' is considered a comment. Options that work without values can be enabled by setting them to 'yes' or '1' and disabled by setting them to 'no' or '0'. Even suboptions can be specified in this way.

EXAMPLE:
# Use Matrox driver by default.
vo=xmga
# I love practicing handstands while watching videos.
flip=yes
# Decode/:encode multiple files from png, start with -mf on
mf= type=png:fps=25

You can also write file-specific configuration files. If you wish to have a config file for a file called 'movie.avi', create a file named 'movie.avi.conf' with the file-specific options in it and put it in ~/.mplayer or in the same directory as the file.

Player Options (mplayer Only)

-, -use-stdin
    Read data from stdin. The -idx option does not work in conjunction with this.
-autoq <quality> (use with -vop pp)
    Dynamically changes the level of postprocessing depending on available spare CPU time. The number you specify will be the maximum level used. Usually you can use some big number. You have to use -vop pp without parameters in order to use this.
-autosync <factor>
    Gradually adjusts the A/:V sync based on audio delay measurements. Specifying -autosync 0, the default, will cause frame timing to be based entirely on audio delay measurements. Specifying -autosync 1 will do the same, but will subtly change the A/:V correction algorithm used. An uneven video frame rate in a movie which plays fine with -nosound can often be helped by setting this to an integer value greater than 1. The higher the value, the closer the timing will be to -nosound. Try -autosync 30 to smooth out problems with sound drivers which do not implement a perfect audio delay measurement. With this value, if large A/:V sync offsets occur, they will only take about 1 or 2 seconds to settle out. This delay in reaction time to sudden A/:V offsets should be the only side-effect of turning this option on, for all sound drivers.
-benchmark
    Prints some statistics on CPU usage and dropped frames at the end. Use in combination with -nosound and -vo null for benchmarking only the video codec.
-edl <filename>
    Enables edit decision list (EDL) actions during playback. Video will be skipped over and audio will be muted and unmuted according to the entries in the given file. See DOCS/documentation.html#edl for details on how to use this.
-edlout <filename>
    Creates a new file and writes edit decision list (EDL) records to that file. During playback, when the user hits 'i', an entry to skip over the last two seconds of playback will be written to the file. This provides a starting point from which the user can fine-tune EDL entries later. See DOCS/documentation.html#edl for details.
-enqueue (GUI only)
    Enqueue files given on the command line in the playlist instead of playing them immediately.
-fixed-vo (BETA CODE!)
    Enforces a fixed video system for multiple files (one (un)initialisation for all files). Therefore only one window will be opened for all files. Currently the following drivers are fixed-vo compliant: x11, xv, xvidix, xmga, gl2, and svga.
-framedrop (also see -hardframedrop)
    Skip displaying some frames to maintain A/:V sync on slow systems. Video filters are not applied to such frames. For B frames even decoding is skipped completely.
-h, -help, --help
    Show short summary of options.
-hardframedrop
    More intense frame dropping (breaks decoding). Leads to image distortion!
-identify
    Show file parameters in easy parsable format. The wrapper script TOOLS/midentify suppresses the other mplayer output and (hopefully) shellescapes the filenames.
-input <commands>
    This option can be used to configure certain parts of the input system. Paths are relative to ~/:.mplayer/.

    NOTE:
    Autorepeat is currently only supported by joysticks.
    Available commands are:

        conf=<file>
            Read alternative input.conf. If given without pathname, ~/:.mplayer is assumed.
        ar-delay
            Delay in msec before we start to autorepeat a key (0 to disable).
        ar-rate
            How many key presses per second when we autorepeat.
        keylist
            Prints all keys that can be bound.
        cmdlist
            Prints all commands that can be bound.
        js-dev
            Specifies the joystick device to use (default is /dev/:input/:js0).
        file
            Read commands from the given file. Mostly useful with a fifo.

-lircconf <file>
    Specifies a configuration file for LIRC (Linux Infrared Remote Control, see http://www.lirc.org) if you don't like the default ~/:.lircrc.
-loop <number>
    Loops movie playback <number> times. 0 means forever.
-menu (BETA CODE)
    Turn on OSD menu support.
-menu-root <value> (BETA CODE)
    Specify the main menu.
-menu-cfg <file> (BETA CODE)
    Use an alternative menu.conf.
-nojoystick
    Turns off joystick support. Default is on, if compiled in.
-nolirc
    Turns off LIRC support.
-nortc  
    Turns off usage of the Linux RTC (real-time clock - /dev/:rtc) as timing mechanism.
-playlist <file>
    Play files according to a playlist (1 file per row or Winamp or ASX format).
-quiet  
    Display less output and status messages.
-really-quiet  
    Display even less output and status messages.
-sdp
    Specifies that the input file is a SDP ('Session Description Protocol') file that describes an RTP session (see http://www.live.com/mplayer/).
-shuffle  
    Play files in random order.
-skin <skin directory> (BETA CODE)
    Load skin from the given directory (WITHOUT path name).

    EXAMPLE:

        -skin fittyfene
            tries Skin/fittyfene. It first checks /usr/local/share/mplayer/ and afterwards ~/.mplayer/.

-slave  
    This option switches on slave mode. This is intended for use of MPlayer as a backend to other programs. Instead of intercepting keyboard events, MPlayer will read simplistic command lines from its stdin. The section SLAVE MODE PROTOCOL explains the syntax.
-softsleep
    Uses high quality software timers. As precise as the RTC without requiring special privileges. Comes at the price of higher CPU consumption.
-speed <0.01-100>
    Set playback speed rate.
-sstep <sec>
    Specifies seconds between displayed frames. Useful for slideshows.

Demuxer/Stream Options

-aid <id> (also see -alang option)
    Select audio channel [MPEG: 0-31 AVI/:OGM: 1-99 ASF/:RM: 0-127 VOB(AC3): 128-159 VOB(LPCM): 160-191] MPlayer prints the available IDs when running in verbose (-v) mode.
-alang <two letter country code> (also see -aid option)
    Works only for DVD playback. It selects the DVD audio language and always tries to play audio streams whose language matches the given code. For the list of available languages, use with the -v option and look at the output.

    EXAMPLE:

        -alang hu,en
            Plays Hungarian and falls back to English if Hungarian is not available.

-audio-demuxer <number> (-audiofile only)
    Force audio demuxer type for -audiofile. Give the demuxer ID as defined in demuxers.h. Use -audio-demuxer 17 to force .mp3 detection.
-audiofile <filename>
    Play audio from an external file (WAV, MP3 or Ogg Vorbis) while viewing a movie.
-bandwidth <value>
    Specify the maximum bandwidth for network streaming (for servers that are able to send content in different bitrates). Usefull if you want to watch live streamed media behind a slow connection.
-cdrom-device <path to device>
    Override default CDROM drive name /dev/:cdrom.
-cache <kbytes>
    This option specifies how much memory (in kbytes) to use when precaching a file/:URL. Especially useful on slow media (default is -nocache).
-cdda <option1:option2>
    This option can be used to tune the CD Audio reading feature of MPlayer.
    Available options are:

        speed=<value>
            set CD spin speed
        paranoia=<0-2>
            set paranoia level

                0: disable checking
                1: overlap checking only (default)
                2:

full data correction and verification

generic-dev=<value>
    use specified generic SCSI device
sector-size=<value>
    atomic read size
overlap=<value>
    force minimum overlap search during verification to <value> sectors.
toc-bias
    Assume that the beginning offset of track 1 as reported in the TOC will be addressed as LBA 0. Some Toshiba drives need this for getting track boundaries correct.
toc-offset=<value>
    Add <value> sectors to the values reported when addressing tracks. May be negative.
(no)skip
    (never) accept imperfect data reconstruction.

-channels <number>
    Change the number of playback channels, defaults to '2' if not specified. If the number of output channels is bigger than the number of input channels empty channels are inserted (unless mixing from mono to stereo, then the mono channel is repeated in both output channels). If the number of output channels is smaller than the number of input channels, results depend on the audio decoder (-afm). MPlayer asks the decoder to decode the audio into as many channels as specified. Now it's up to the decoder to fulfill the requirement. If the decoder outputs more channels than requested, the exceeding channels are truncated. This is usually only important when playing videos with AC3 audio (like DVDs). In that case liba52 does the decoding by default and correctly downmixes the audio into the requested number of channels.

    NOTE:
    This option is honored by codecs (AC3 only) filters (surround) and ao drivers (OSS at least).
    Available options are:

        2
            Stereo
        4
            Surround
        6

Full 5.1

-chapter <chapter id>[-<end chapter id>]
    Specify which chapter to start playing at. Optionally specify which chapter to end playing at (default: 1). Examples can be found below.
-csslib <filename>
    (old-style DVD option) This option is used to override the default location of libcss.so.
-cuefile <filename> (see -vcd too)
    Play (S)VCD from CDRwin's (bin/cue fileformat) disk image, described by the specified file.
-demuxer <number>
    Force demuxer type. Give the demuxer ID as defined in demuxers.h. Use -demuxer 17 to force .mp3 detection.
-dumpaudio (MPLAYER only)
    Dumps raw compressed audio stream to ./:stream.dump (useful with mpeg/:ac3).
-dumpfile <filename> (MPLAYER only)
    Specify which file MPlayer should dump to. Should be used together with -dumpaudio / -dumpvideo / -dumpstream.
-dumpstream (MPLAYER only)
    Dumps the raw stream to ./:stream.dump. Useful when ripping from DVD or network.
-dumpvideo (MPLAYER only)
    Dump raw compressed video stream to ./:stream.dump (not very usable).
-dvd <title id>
    Tell MPlayer which movies (specified by title id) to play. For example sometimes '1' is a trailer, and '2' is the real movie.

    NOTE:
    Sometimes deinterlacing is required for DVD playback, see the -vop pp=0x20000 option.
-dvd-device <path to device>
    Override default DVD device name /dev/:dvd.
-dvdangle <angle id>
    Some DVD discs contain scenes that can be viewed from multiple angles. Here you can tell MPlayer which angles to use (default: 1). Examples can be found below.
-dvdauth <DVD device>
    (old-style DVD option) Turns on DVD authentication using the given device.
-dvdkey <CSS key>
    (old-style DVD option) When decoding a VOB file copied undecrypted from DVD, this option gives the CSS key needed to decrypt the VOB (the key is printed when authenticating with the DVD drive using -dvdauth).
-dvdnav (BETA CODE!)
    Force usage of libdvdnav.
-forceidx
    Force rebuilding of INDEX. Useful for files with broken index (desyncs, etc). Seeking will be possible. You can fix the index permanently with MEncoder (see the documentation).
-fps <value>
    Override video framerate (if value is wrong/:missing in the header) (float number).
-frames <number>
    Play/:convert only first <number> frames, then quit.
-hr-mp3-seek (.MP3 only)
    Hi-res mp3 seeking. Default is: enabled when playing from external MP3 file, as we need to seek to the very exact position to keep A/:V sync. It can be slow especially when seeking backwards - it has to rewind to the beginning to find the exact frame.
-idx (also see -forceidx)
    Rebuilds INDEX of the AVI if no INDEX was found, thus allowing seeking. Useful with broken/:incomplete downloads, or badly created AVIs.
-mc <seconds/frame>
    Maximum A-V sync correction per frame (in seconds).
-mf <option1:option2:...>
    Used when decoding from multiple PNG or JPEG files.
    Available options are:

        on
            turns on multifile support
        w=<value>
            width of the output (autodetect)
        h=<value>

        type=<value>
            type of input files (available types: jpeg, png, tga)

-ni (.AVI only)
    Force usage of non-interleaved AVI parser (fixes playing of some bad AVI files).
-nobps (.AVI only)
    Do not use average byte/:sec value for A-V sync (AVI). Helps with some AVI files with broken header.
-noextbased
    Disables filename-extension based demuxer selection. By default, when file type (demuxer) cannot be detected reliably (the file has no header or it is not reliable enough), the filename extension is used to select demuxer. It always falls back to content-based demuxer selection.
-passwd <password> (see -user option too)
    Specify password for http authentication.
-rawaudio <option1:option2:...>
    This option lets you play raw audio files. It may also be used to play audio CDs which are not 44KHz 16Bit stereo.
    Available options are:

        on
            use raw audio demuxer
        channels=<value>
            number of channels
        rate=<value>
            rate in samples per second

            colorspace (fourcc) in hex
        size=<value>

frame size in bytes

-rtsp-stream-over-tcp
    Used with 'rtsp://' URLs to specify that the resulting incoming RTP and RTCP packets be streamed over TCP (using the same TCP connection as RTSP). This option may be useful if you have a broken Internet connection that does not pass incoming UDP packets (see http://www.live.com/mplayer/).
-skipopening
    Skip DVD opening (dvdnav only).
-sb <byte position> (see -ss option too)
    Seek to byte position. Useful for playback from CDROM images / .VOB files with junk at the beginning.
-srate <Hz>
    Forces the given audio playback rate, changing video speed to keep a-v sync. MEncoder passes this value to lame for resampling.
-ss <time> (see -sb option too)
    Seek to given time position.

    EXAMPLE:

        -ss 56
            seeks to 56 seconds
        -ss 01:10:00

seeks to 1 hour 10 min

-tv <option1:option2:...>
    This option enables the TV grabbing feature of MPlayer.

    NOTE:
    MPlayer doesn't accept colons so type dots instead in the device ID (e.g. hw.0,0 instead of hw:0,0).
    Be advised that although you can select any samplerate when using ALSA, the LAME audio codec is able to encode only the 'standard' samplerates. You'll get an .avi file with no sound when you choose an odd samplerate and use this codec.
    Available options are:

        on
            use TV input
        noaudio
            no sound
        driver=<value>
            available: dummy, v4l, bsdbt848
        device=<value>
            Specify other device than the default /dev/:video0.
        input=<value>
            Specify other input than the default 0 (Television) (see output for a list)
        freq=<value>
            Specify the frequency to set the tuner to (e.g. 511.250). Not compatible with channels parameter.
        outfmt=<value>

            maximum size of the capture buffer in megabytes (default: dynamical)
        norm=<value>
            available: PAL, SECAM, NTSC
        channel=<value>
            Set tuner to <value> channel.
        chanlist=<value>
            available: europe-east, europe-west, us-bcast, us-cable, etc
        channels=<channel>-<name>,<channel>-<name>,...
            Set names for channels. Use _ for spaces in names (or play with quoting ;-). The channel names will then be written using OSD, and the commands tv_step_channel, tv_set_channel and tv_last_channel will then be usable using a remote (see lirc). Not compatible with frequency parameter. Warning: The channel number will then be the position in the 'channels' list, beginning with 1. Example: use tv://1, tv://2, tv_set_channel 1, tv_set_channel 2, etc.
        audiorate=<value>
            set audio capture bitrate
        forceaudio
            capture audio even if there are no audio sources reported by v4l
        alsa
            capture from ALSA
        amode=<0-3>
            choose an audio mode:

                0: mono
                1: stereo
                2: language 1
                3:

language 2

forcechan=<1-2>
    By default, the count of recorded audio channels is determined automatically by querying the audio mode from the tv card. This option allows to force stereo/:mono recording regardless of the amode option and the values returned by v4l. This can be used for troubleshooting when the tv card is unable to report the current audio mode.
adevice=<value>
    set an audio device

        /dev/:... for OSS

hardware ID for ALSA

audioid=<value>
    choose an audio output of the capture card, if it has more of them
[volume|bass|treble|balance]=<0-65535>
    These options set parameters of the mixer on the video capture card. They will have no effect, if your card doesn't have one.
immediatemode=<bool>
    A value of 0 means capture and buffer audio and video together (default for mencoder). A value of 1 (default for mplayer) means to do video capture only and let the audio go through a loopback cable from the TV card to the soundcard.

-user <user name> (see -passwd option too)
    Specify user name for http authentication.
-vcd <track>
    Play video CD track from a device or image file (see -cuefile).
-vid <id>
    Select video channel [MPG: 0-15 ASF: 0-255].
-vivo <sub-options> (DEBUG CODE)
    Force audio parameters for the .vivo demuxer (for debugging purposes).

Osd/Sub Options

bold black outline

-font <path to font.desc file>
    Search for the OSD/:SUB fonts in an alternative directory (default for normal fonts: ~/:.mplayer/:font/:font.desc, default for FreeType fonts: ~/.mplayer/:subfont.ttf).

    NOTE:
    With FreeType, this option determines path to the text font file.
    The -subfont-* options are available only with FreeType support compiled in.

    EXAMPLE:

        -font ~/:.mplayer/:arial-14/:font.desc

-font ~/:.mplayer/:arialuni.ttf

-noautosub
    Turns off automatic loading of subtitle files.
-overlapsub

total time

-sid <id> (also see -slang option)
    Turns on DVD subtitle displaying. Also, you MUST specify a number which corresponds to a DVD subtitle language (0-31). For the list of available subtitles, use with the -v option and look at the output.
-slang <two letter country code> (also see -sid option)
    Works only for DVD playback. Turns on/:selects DVD subtitle language. For the list of available subtitles, use with the -v option and look at the output.

-sub-bg-color <0-255>
    Specify the color value for subtitles and OSD backgrounds. Currently subtitles are grayscale so this value is equivalente to the intensity of the color. The 255 value means white and 0 black.
-subcc 
    Display DVD Closed Caption (CC) subtitles. These are NOT the VOB subtitles, these are special ASCII subtitles for the hearing impaired encoded in the VOB userdata stream on most region 1 DVDs. CC subtitles have not been spotted on DVDs from other regions so far.

        1
            proportional to movie height
        2
            proportional to movie width

-spugauss <0.0-3.0>
    Variance parameter of gaussian used by -spuaa 4. Higher means more blur. The default is 1.0.

Audio Output Options (mplayer Only)

-abs <value> (OBSOLETE)
    Override audio driver/:card buffer size detection, -ao oss only
-af <plugin1,plugin2,plugin3[=options],...>
    Activate a comma separated list of audio filters and their options.
    Available filters are:

        resample[=srate[:sloppy][:type]]
            Changes the sample rate of the audio stream to an integer srate (Hz). It only supports the 16 bit little endian format.
        channels[=nch]
            Change the number of channels to nch output channels. If the number of output channels is bigger than the number of input channels empty channels are inserted (except mixing from mono to stereo, then the mono channel is repeated in both of the output channels). If the number of output channels is smaller than the number of input channels the exceeding channels are truncated.
        format[=bps,f]
            Select the format f and bits per sample bps used for output from the filter layer. The option bps is an integer and denotes bytes per sample. The format f is a string containing a concatenated mix of:

            float or int
            unsigned or signed
            le or be (little or big endian)
        volume[=v:sc]
            Select the output volume level. This filter is not reentrant and can therefore only be enabled once for every audio stream.

                v: desired gain in dB for all channels in the stream. The gain can be set from -200dB to +40dB (where -200dB mutes the sound completely and +40dB equals a gain of 1000).
                sc: enable soft clipping.

pan[=n:l01:l02:..l10:l11:l12:...ln0:ln1:ln2:...]
    Mixes channels arbitrarily, see DOCS/sound.html for details.

        n: number of output channels (1 - 6).
        lij: how much of input channel j is mixed into output channel i.

sub[=fc:ch]
    Add sub-woofer channel.

        fc: Cutoff frequency for low-pass filter (20Hz to 300Hz) default is 60Hz.
        ch: channel number for the sub-channel.

surround[=d]
    Decoder for matrix encoded surround sound, works on many 2 channel files.

        d: delay time in ms for the rear speakers (0ms to 1000ms) default is 15ms.

delay[=ch1:ch2:...]
    Delays the sound output. Specify the delay separately for each channel in milliseconds (floating point number between 0 and 1000).

-af-adv <force=(0-3):list=(filters)> (see -af option too)
    Specify advanced audio filter options:

        force=<0-3>
            Forces the insertion of audio filters to one of the following:

    If the list has a trailing ',' it will fallback to drivers not listed.

    EXAMPLE

        -ao oss:/:dev/:dsp2,oss:/:dev/:dsp1,

-nowaveheader (-ao pcm only)
    Don't include wave header. Used for RAW PCM.

Video Output Options (mplayer Only)

-aa* (-vo aa only)
    You can get a list and an explanation of available options executing mplayer -aahelp
-bpp <depth>
    Use different color depth than autodetect. Not all -vo drivers support it (fbdev, dga2, svga, vesa).
-brightness <-100-100>
    Adjust brightness of video output (default 0). It changes intensity of RGB components of video signal from black to white screen.
-contrast <-100-100>
    Adjust contrast of video output (default 0). Works in similar manner as brightness.
-dfbopts <value> (-vo directfb2 only)
    Specify a parameter list for the directfb driver.
-display <name>
    Specify the hostname and display number of the X server you want to display on.

    EXAMPLE:

-display xtest.localdomain:0

-double
    Enables doublebuffering. Fixes flicker by storing two frames in memory, and displaying one while decoding another. Can affect OSD. Needs twice the memory of a single buffer, so it won't work on cards with very little video memory.
-dr   
    Turns on direct rendering (not supported by all codecs and video outputs) (default is off). Warning: may cause OSD/:SUB corruption!
-dxr2 <option1:option2:...>
    This option is used to control the dxr2 driver. Note: The lavc filter is now auto inserted if you try to play a non MPEG1/2 format so all formats supported by MPlayer should play out of the box (if you have the CPU power needed to encode on the fly). The overlay chipset used on the dxr2 is of pretty bad quality but the default settings should work for everybody. The OSD may be usable with the overlay (not on TV) by drawing it in the colorkey. With the default colorkey settings you may get variable results, usually you will see the colorkey around the characters or some other funny effect. But if you properly adjust the colorkey settings you should be able to get acceptable results.

-forcexv (SDL only)
    Force using XVideo.
-fs   
    Fullscreen playing (centers movie, and makes black bands around it). Toggle it with the 'f' key (not all video outputs support it). See also -zoom.
-fsmode-dontuse <0-31> (OBSOLETE) (use -fs option)
    Try this option if you still experience fullscreen problems.
-fstype <type1,type2,...>
    Specify a priority list of fullscreen layer setting modes to be used.

    The default order is "layer,stays_on_top,above,fullscreen". It will be used as a fallback in case of specifying incorrect or unsupported modes.
    If you experience problems with fullscreen window being covered by other windows try using different order.

    NOTE:
    See -fstype help for a full list of available modes.
-geometry x[%][:y[%]] or [WxH][+x+y]
    Adjust where the output is on the screen initially. The x and y specifications are in pixels measured from the top-right of the screen to the top-right of the image being displayed, however if a percentage sign is given after the argument it turns the value into a percentage of the screen size in that direction. It also supports the standard option format to the standard X -geometry option. The values given must be integers.

    Note: This option is only supported by a few vo's, including tdfxfb, fbdev and xv.

-nokeepaspect
    Do not keep window aspect ratio when resizing X11 windows (Works currently only with -vo x11, xv, xmga and xvidix and your window manager needs to understand window aspect hints.).

-noslices
    Disable drawing video by 16-pixel height slices/:bands, instead draws the whole frame in a single run. May be faster or slower, depending on card/:cache. It has effect only with libmpeg2 and libavcodec codecs.
-panscan <0.0-1.0>
    Enables Pan & Scan functionality, i.e. in order to display a 16:9 movie on a 4:3 display, the sides of the movie are cropped to get a 4:3 image which fits the screen. This function works only with the xv, xmga, mga and xvidix video out drivers.
    The range controls how much of the image is cropped.

In cinerama mode the movie is distributed over more than one TV (or beamer) to create a larger screen. Options appearing after the n-th -zrcrop apply to the n-th MJPEG card, each card should at least have a -zrdev in addition to the -zrcrop. For examples, see the output of -zrhelp and the Zr section of the documentation.
-zrdev <device> (-vo zr only)
    Specify the device special file that belongs to your MJPEG card, by default this driver takes the first v4l device it can find.
-zrfd (-vo zr only)

        -vc ffmpeg12,mpeg12,
            try libavcodec's MPEG1/:2 codec, then libmpeg2,

then others

-vfm <driver1,driver2,...>
    Specify a priority list of video drivers to be used, according to their driver name in codecs.conf. It falls back to default if none is ok.

    NOTE:
    If libdivxdecore support was compiled in, then odivx and divx4 now contains just the same DivX4 codec, but different APIs to reach it. For difference between them and when to use which, check the DivX4 section in the documentation.
    See -vfm help for a full list of available drivers.

    EXAMPLE:

        -vfm ffmpeg,dshow,vfw
            try the libavcodec, then Directshow, then VFW codecs and fallback to the others, if still none is ok
        -vfm xanim

try XAnim codecs first

-vop <...,filter3[=options],filter2,filter1>
    Activate a comma separated list of video filters and their options in reverse order.

    NOTE:
    The parameters are optional and if omitted, some of them are set to default values. Use -1 to keep the default value. Parameters w:h means width x height in pixels, x:y means x;y position counted from the upper left corner of the bigger image.
    To get a full list of available plugins, see -vop help.
    Available filters are:

        crop[=w:h:x:y]
            Crops the given part of the image and discards the rest. Useful to remove black bands from widescreen movies.
        cropdetect[=0-255]
            Calculates necessary cropping parameters and prints the recommended parameters to stdout. The threshold can be optionally specified from nothing (0) to everything (255). (default: 24)
        rectangle[=w:h:x:y]
            Draws a rectangle of the requested width and height at the specified coordinates over the image (used to test crop). (default: maximum w/:h, upper left x/:y position)
        expand[=w:h:x:y:o]
            Expands (not scales) movie resolution to the given value and places the unscaled original at coordinates x y. Negative values for w and h are treated as offsets to the original size. For example, expand=0:-50:0:0 adds a 50 pixel border to the bottom of the picture. Can be used for placing subtitles/:OSD in the resulting black bands (default: original w/:h, centered x/:y). The last parameter (de)activates OSD rendering (default: 0=disabled).
        flip
            Flips the image upside down. See also option -flip.
        mirror
            Flips the image on Y axis.
        rotate[=<0-7>]
            Rotates and flips (optional) the image +/:- 90 degrees. For parameters between 4-7 rotation is only done if the movie's geometry is portrait and not landscape.
        scale[=w:h[:c[:p]]]
            Scales the image with the software scaler (slow) and performs a YUV<->RGB colorspace conversion (see -sws option too). The value 0 is used for scaled (aspect) destination w/:h. (default: original w/:h, destination w/:h with -zoom) Optionaly chroma skipping (c from 0-3) and scaling parameters can be specified. (see the -sws option for details)
        yuy2
            Forces software YV12/:I420 or 422P to YUY2 conversion.
        rgb2bgr[=swap]
            RGB 24/:32 <-> BGR 24/:32 colorspace conversion with optional R <-> B swapping.
        palette
            RGB/:BGR 8 -> 15/:16/:24/:32bpp colorspace conversion using palette.
        format[=fourcc]
            Restricts the colorspace for next filter. It does not do any conversion. Use together with the scale filter for a real conversion.
        pp[=filter1[:option1[:option2...]]/[-]filter2...]
            This option enables usage of MPlayer's internal postprocessing filter, and also gives an interface where you can pass options to the named filter. To get a list of available filters, use -pphelp.
            Note that each sub-filter must be separated with a / sign.
            Each filter defaults to 'c' (chrominance).
            The keywords accept a '-' prefix to disable the option.
            A ':' followed by a letter may be appended to the option to indicate its scope:

                a: Automatically switches the filter off if the CPU is too slow.
                c: Do chrominance filtering, too.
                y: Do not do chrominance filtering (only luminance filtering).

    EXAMPLES:


    -vop pp=hb/vb/dr/al/lb
    -vop pp=hb/vb/dr/al
    Default filters without brightness/:contrast correction:
    -vop pp=de/-al
    Enable default filters & temporal denoiser:
    -vop pp=de/tn:1:2:3
    Deblock horizontal only luminance and switch vertical deblocking on or off automatically depending on available CPU time:
    -vop pp=hb:y/vb:a -autoq 6

lavc[=quality:fps]
    Realtime MPEG1 encoder for use with DVB/:DXR3 (libavcodec)
fame
    Realtime MPEG1 encoder for use with DVB/:DXR3 (libfame)
dvbscale[=aspect]
    Set up optimal scaling for DVB cards. (aspect = DVB_HEIGHT*ASPECTRATIO, default: 768)
noise[=luma[u][t|a][h][p]:chroma[u][t|a][h][p]]
    Adds noise

        <0-100>: luma noise
        <0-100>: chroma noise
        u: uniform noise
        t: temporal noise
        a: averaged temporal noise
        h: high quality
        p: mix random noise with a (semi)r

egular pattern

denoise3d[=luma:chroma:time]
    This filter aims to reduce image noise producing smooth images and making still images really still (This should enhance compressibility.). It can be given from 0 to 3 parameters. If you omit a parameter, a reasonable value will be inferred.

        luma:    spatial luma strength (default = 4)
        chroma:    spatial chroma strength (default = 3)
        time:    temporal strength (default = 6)

eq[=bright:cont]
    Activates the software equalizer with interactive controls like the hardware eq controls. The values can be from -100 to 100.
eq2[=gamma:contrast:brightness:saturation:rg:gg:bg]
    Alternative software equalizer that uses lookup tables (very slow), allowing gamma correction in addition to simple brightness, contrast and saturation adjustment. Note that it uses the same MMX optimized code as -vop eq if all gamma values are 1.0! The parameters are given as floating point values. Defaults are gamma=1.0, contrast=1.0, brightness=0.0 and saturation=1.0. Parameters rg, gg, bg are the independent gamma values for the Red, Green and Blue components, all default to 1.0. The values are 0.1-10 for gammas, -2-2 for contrast (negative values result in negative image) -1-1 for brightness and 0-3 for saturation.
halfpack[=f]
    Convert planar YUV 4:2:0 to half-height packed 4:2:2, downsampling luma but keeping all chroma samples. Useful for output to low-resolution display devices when hardware downscaling is poor quality or is not available. Can also be used as a primitive luma-only deinterlacer with very low cpu usage. By default, halfpack averages pairs of lines when downsampling. The optional parameter f can be 0 to only use even lines, or 1 to only use odd lines. Any other value for f gives the default (averaging) behavior.
dint[=sense:level]
    Detects and drops first of interlaced frames in video stream. Values can be from 0.0 to 1.0 - first (default 0.1) is relative difference between neighbor pixels, second (default 0.15) is what part of image have to be detected as interlaced to drop the frame.
lavcdeint
    Use libavcodec's deinterlace filter.
unsharp=l|cWxH:amount[:l|cWxH:amount]
    Unsharp mask / gaussian blur.

        l: apply effect on luma component
        c: apply effect on chroma components
        WxH: width and height of the matrix, odd sized in both directions (min = 3x3, max = 13x11 or 11x13, usually something between 3x3 and 7x7)
        amount: relative amount of sharpness / blur to add to the image (amount < 0 = blur, amount > 0 = sharpen, usually something between -1.5 and 1.5)

swapuv
    Swap U & V plane.
il=[d|i][s][:[d|i][s]]
    (de)interleaves lines. The goal of this filter is to add ability of processing interlaced images pre-field without deinterlacing it. You can filter your interlaced dvd and playback on TV without breaking the interlacing. While deinterlacing (with the post processing filter) removes the interlacing permamently (by smoothing averaging etc) deinterleaving splits the frame into 2 fields (so called half pictures), so you can process (filter) them independently and then re-interleave them.

        d: deinterleave
        i: interleave
        s: swap fields (exchange even & odd lines)

field[=n]
    Extracts a single field from interlaced image using stride arithmetic to avoid wasting cpu time. The optional argument n specifies whether to extract the even or the odd field (depending on whether n is even or odd).
boxblur=radius:power[:radius:power]
    box blur

        radius: size of the filter
        power:

how often the filter should be applied

sab=rad:pfilter:cDiff[:rad:pfilter:cDiff]
    shape adaptive blur

        rad: blur filter strength (~0.1-4.0) (slower if larger)
        pfilter: prefilter strength (~0.1-2.0)
        cDiff: how different the pixels are allowed to be to be considered (~0.1-100.0)

smartblur=rad:strength:thresh[:rad:strength:thresh]
    smart blur

        rad: blur filter strength (~0.1-5.0) (slower if larger)
        strength: blur (0.0-1.0) or sharpen (-1.0-0.0)
        thresh: filter all (0), filter flat areas (0-30) or filter edges (-30-0)

perspective=x0:y0:x1:y1:x2:y2:x3:y3:t
    perspective correcture

        x0,y0,...: coordinates of the top left, top right, bottom left, bottom right corners
        t: linear (0) or cubic resampling (1)

2xsai
    Use the 2x scale and interpolate algorithm for scaling and smoothing images.
1bpp
    1bpp bitmap to YUV/BGR 8/15/16/32 conversion
bmovl=hidden:opaque:<fifo>
    Read bitmaps from a FIFO and display them in window.

        hidden: sets the default value of the 'hidden' flag (boolean)
        opaque: flag switching between alphablended (transparent) and opaque (fast) mode
        fifo: path/filename for the FIFO (named pipe connecting mplayer -vop bmovl to the controlling application)

    FIFO commands are:

    RGBA32 width height xpos ypos alpha clear
    followed by width*height*4 bytes of raw RGBA32 data.

    ABGR32 width height xpos ypos alpha clear
    followed by width*height*4 bytes of raw ABGR32 data.

    RGB24 width height xpos ypos alpha clear
    followed by width*height*3 bytes of raw RGB32 data.

    BGR24 width height xpos ypos alpha clear
    followed by width*height*3 bytes of raw BGR32 data.

    ALPHA width height xpos ypos alpha

    change alpha for area

    CLEAR width height xpos ypos

    clear area

    OPAQUE
    disable all alpha transparency. Send "ALPHA 0 0 0 0 0" to enable it again.

    HIDE

    hide bitmap

    SHOW
    show bitmap

    Arguments are:

    width, height: size of image/area
    xpos, ypos: start blitting at X/Y position
    alpha: set alpha difference. 0 means same as original, 255 makes everything opaque, -255 makes everything transparent. If you set this to -255 you can then send a sequence of ALPHA-commands to set the area to -225, -200, -175 etc for a nice fade-in-effect! ;)
    clear: clear the framebuffer before blitting. 1 means clear, if 0, the image will just be blitted on top of the old one, so you don't need to send 1,8MB of RGBA32 data everytime a small part of the screen is updated.

-x <x> (MPLAYER only)
    Scale image to x width (if sw/:hw scaling available). Disables aspect calculations.
-xvidopts <option1:option2:...>
    Specify additional parameters when decoding with XviD.

        dr2
            Activate direct rendering method 2.
        nodr2
            Deactivate direct rendering method 2.

-xy <x>

        x<=8
            Scale image by factor <x>.
        x>8
            Set width to <x> and calculate height to keep correct aspect ratio.

-y <y> (MPLAYER only)
    Scale image to y height (if sw/:hw scaling available). Disables aspect calculations.
-zoom 
    Allow software scaling, where available. Could be used to force scaling with -vop scale.

    NOTE:
    -vop scale will IGNORE options -x / -y / -xy / -fs / -aspect without -zoom.

Encoding Options (mencoder Only)

-audio-density <1-50>
    Number of audio chunks per second (default is 2 for 0.5s long audio chunks).

    NOTE:
    CBR only, VBR ignores this as it puts each packet in a new chunk.
-audio-delay <0.0-...>
    Sets the audio delay field in the header. Default is 0.0, negative values do not work. This does not delay the audio while encoding, but the player will see the default audio delay, sparing you the use of the -delay option.
-audio-preload <0.0-2.0>
    Sets up audio buffering time interval (default: 0.5s).
-divx4opts <option1:option2:...>
    If encoding to DivX4, you can specify its parameters here.
