Description

mplayer is a movie player for Linux (runs on many other platforms and CPU architectures, see the documentation). It plays most MPEG/VOB, AVI, ASF/WMA/WMV, RM, QT/MOV/MP4, Ogg/OGM, MKV, VIVO, FLI, NuppelVideo, yuv4mpeg, FILM and RoQ files, supported by many native and binary codecs. You can watch Video CD, SVCD, DVD, 3ivx, DivX 3/4/5 and even WMV movies, too.

MPlayer supports a wide range of video and audio output drivers. It works with X11, Xv, DGA, OpenGL, SVGAlib, fbdev, AAlib, libcaca, DirectFB, Quartz, Mac OS X CoreVideo, but you can also use GGI, SDL (and 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, Hauppauge PVR (IVTV), DXR2 and DXR3/Hollywood+. Most of them support software or hardware scaling, so you can enjoy movies in fullscreen mode.

MPlayer has an onscreen display (OSD) for status information, nice big antialiased shaded subtitles and visual feedback for keyboard controls. European/ISO8859-1,2 (Hungarian, English, Czech, etc), Cyrillic and Korean fonts are supported along with 12 subtitle formats (MicroDVD, SubRip, OGM, SubViewer, Sami, VPlayer, RT, SSA, AQTitle, JACOsub, PJS 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 MPEG-4 (DivX/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 filter 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.

Usage examples to get you started quickly can be found at the end of this man page.

Interactive Control

MPlayer has a fully configurable, command-driven control layer which allows you to control MPlayer using keyboard, mouse, joystick or remote control (with LIRC). See the -input option for ways to customize it.

Usage

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

If an option is marked as (XXX only), it will only work in combination with the XXX option or if XXX is compiled in.

NOTE: The suboption parser (used for example for -ao pcm suboptions) supports a special kind of string-escaping intended for use with external GUIs.
It has the following format:
%n%string_of_length_n
EXAMPLES:
mplayer -ao pcm:file=%10%C:test.wav test.avi
Or in a script:
mplayer -ao pcm:file=%'expr length "$NAME"'%"$NAME" test.avi

Configuration Files

You can put all of the options in configuration files which will be read every time MPlayer/MEncoder 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'. The configuration file for MEncoder is 'mencoder.conf' in your configuration directory (e.g. /etc/mplayer or /usr/local/etc/mplayer), the user specific one is '~/.mplayer/ mencoder.conf. 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' or 'true' and disabled by setting them to 'no' or '0' or 'false'. Even suboptions can be specified in this way.

You can also write file-specific configuration files. If you wish to have a configuration 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/. You can also put the configuration file in the same directory as the file to be played, as long as you give the -use-filedir-conf option (either on the command line or in your global config file).

EXAMPLE MPLAYER CONFIGURATION FILE:

# 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://filemask
mf=type=png:fps=25
# Eerie negative images are cool.
vf=eq2=1.0:-0.8

EXAMPLE MENCODER CONFIGURATION FILE:

# Make MEncoder output to a default filename.

Profiles

To ease working with different configurations profiles can be defined in the configuration files. A profile starts with its name between square brackets, e.g. '[my-profile]'. All following options will be part of the profile. A description (shown by -profile help) can be defined with the profile-desc option. To end the profile, start another one or use the profile name 'default' to continue with normal options.

EXAMPLE MENCODER PROFILE:

[mpeg4]
profile-desc="MPEG4 encoding"
ovc=lacv=yes
lavcopts=vcodec=mpeg4:vbitrate=1200

[mpeg4-hq]
profile-desc="HQ MPEG4 encoding"
profile=mpeg4
lavcopts=mbd=2:trell=yes:v4mv=yes

General Options

-codecs-file <filename> (also see -afm, -ac, -vfm, -vc)

Override the standard search path and use the specified file instead of the builtin codecs.conf.

-include <configuration file>

Specify configuration file to be parsed after the default ones.

-list-options

Prints all available options.

-msgcharset <charset>

Convert console messages to the specified character set (default: autodetect). Text will be in the encoding specified with the --charset configure option. Set this to "noconv" to disable conversion (for e.g. iconv problems).
NOTE: The option takes effect after command line parsing has finished. The MPLAYER_CHARSET environment variable can help you get rid of the first lines of garbled output.

-msglevel <all=<level>:<module>=<level>:...>

Control verbosity directly for each module. The 'all' module changes the verbosity of all the modules not explicitly specified on the command line. See '-msglevel help' for a list of all modules.
NOTE: Messages printed before the command line is parsed can be controlled only by the MPLAYER_VERBOSE environment variable, which applies to all modules.
Available levels:

-1

complete silence

fatal messages only

error messages

warning messages

short hints

informational messages

status messages (those hidden by -quiet)

verbose messages

debug level 2

debug level 3

debug level 4

-quiet

Make console output less verbose; in particular, prevents the status line (i.e. A: 0.7 V: 0.6 A-V: 0.068 ...) from being displayed. Particularly useful on slow terminals or broken ones which do not properly handle carriage return (i.e. \r).

-priority <prio> (Windows only)

Set process priority for MPlayer according to the predefined priorities available under Windows. Possible values of <prio>:

WARNING: Using realtime priority can cause system lockup.

-profile <profile1,profile2,...>

Use the given profile(s), -profile help displays a list of the defined profiles.

-really-quiet (also see -quiet)

Display even less output and status messages than with -quiet.

-show-profile <profile>

Show the description and content of a profile.

-use-filedir-conf

Look for a file-specific configuration file in the same directory as the file that is being played.
WARNING: may be dangerous if playing from untrusted media.

-v

Increment verbosity level, one level for each -v found on the command line.

PLAYER OPTIONS (MPLAYER ONLY)

-autoq <quality> (use with -vf [s]pp)

Dynamically changes the level of postprocessing depending on the 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 -vf [s]pp without parameters in order for this to work.
-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. An uneven video framerate 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 of playback. Use in combination with -nosound and -vo null for benchmarking only the video codec.
NOTE: With this option MPlayer will also ignore frame duration when playing only video (you can think of that as infinite fps).
-colorkey <number>: Changes the colorkey to an RGB value of your choice. 0x000000 is black and 0xffffff is white. Only supported by the cvidix, fbdev, svga, vesa, winvidix, xmga, xvidix, xover, xv (see -vo xv:ck), xvmc (see -vo xv:ck) and directx video output drivers.
-nocolorkey: Disables colorkeying. Only supported by the cvidix, fbdev, svga, vesa, winvidix, xmga, xvidix, xover, xv (see -vo xv:ck), xvmc (see -vo xv:ck) and directx video output drivers.
-crash-debug (DEBUG CODE): Automatically attaches gdb upon crash or SIGTRAP. Support must be compiled in by configuring with --enable-crash-debug.
-edlout <filename>: Creates a new file and writes edit decision list (EDL) records to it. During playback, the user hits 'i' to mark the start or end of a skip block. This provides a starting point from which the user can fine-tune EDL entries later. See http://www.mplayerhq.hu/DOCS/HTML/en/edl.html for details.
-enqueue (GUI only): Enqueue files given on the command line in the playlist instead of playing them immediately.
-fixed-vo: Enforces a fixed video system for multiple files (one (un)initialization for all files). Therefore only one window will be opened for all files. Currently the following drivers are fixed-vo compliant: gl, gl2, mga, svga, x11, xmga, xv, xvidix and dfbmga.
-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.
-(no)gui: Enable or disable the GUI interface (default depends on binary name). Only works as the first argument on the command line. Does not work as a config-file option.
-h, -help, --help: Show short summary of options.
-hardframedrop: More intense frame dropping (breaks decoding). Leads to image distortion!
-identify: Shorthand for -msglevel identify=4. Show file parameters in an easily parseable format. Also prints more detailed information about subtitle and audio track languages and IDs. In some cases you can get more information by using -msglevel identify=6. For example, for a DVD it will list the time length of each title, as well as a disk ID. The wrapper script TOOLS/midentify suppresses the other MPlayer output and (hopefully) shellescapes the filenames.
-idle (also see -slave): Makes MPlayer wait idly instead of quitting when there is no file to play. Mostly useful in slave mode where MPlayer can be controlled through input commands.
-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=<filename>

Specify input configuration file other than the default ~/.mplayer/input.conf. ~/.mplayer/<filename> is assumed if no full path is given.

ar-delay

Delay in milliseconds before we start to autorepeat a key (0 to disable).

ar-rate

Number of key presses to generate per second on autorepeat.

keylist

Prints all keys that can be bound to commands.

cmdlist

Prints all commands that can be bound to keys.

js-dev

Specifies the joystick device to use (default: /dev/ input/js0).

file=<filename>

Read commands from the given file. Mostly useful with a FIFO.
NOTE: When the given file is a FIFO MPlayer opens both ends so you can do several 'echo "seek 10" > mp_pipe' and the pipe will stay valid.

-key-fifo-size <2-65000>: Specify the size of the FIFO that buffers key events (default: 10). A FIFO of size n can buffer (n-1) events. If it is too small some events may be lost (leading to "stuck mouse buttons" and similar effects). If it is too big, MPlayer may seem to hang while it processes the buffered events. To get the same behavior as before this option was introduced, set it to 2 for Linux or 1024 for Windows.
-lircconf <filename> (LIRC only): Specifies a configuration file for LIRC (default: ~/.lircrc).
-list-properties: Print a list of the available properties.
-loop <number>: Loops movie playback <number> times. 0 means forever.
-menu (OSD menu only): Turn on OSD menu support.
-menu-cfg <filename> (OSD menu only): Use an alternative menu.conf.
-menu-root <value> (OSD menu only): Specify the main menu.
-menu-startup (OSD menu only): Display the main menu at MPlayer startup.
-mouse-movements: Permit MPlayer to receive pointer events reported by the video output driver (currently only derivatives of X11 are supported). Necessary to select the buttons in DVD menus.
-noconsolecontrols: Prevent MPlayer from reading key events from standard input. Useful when reading data from standard input. This is automatically enabled when - is found on the command line. There are situations where you have to set it manually, e.g. if you open /dev/stdin (or the equivalent on your system), use stdin in a playlist or intend to read from stdin later on via the loadfile or loadlist slave commands.
-nojoystick: Turns off joystick support.
-nolirc: Turns off LIRC support.
-nomouseinput (X11 only): Disable mouse button press/release input (mozplayerxp's context menu relies on this option).
-rtc (RTC only): Turns on usage of the Linux RTC (realtime clock - /dev/rtc) as timing mechanism. This wakes up the process every 1/1024 seconds to check the current time. Useless with modern Linux kernels configured for desktop use as they already wake up the process with similar accuracy when using normal timed sleep.
-playing-msg <string>: Print out a string before starting playback. The following expansions are supported:; ${NAME}

Expand to the value of the property NAME.

$(NAME:TEXT)

Expand TEXT only if the property NAME is available.

-playlist <filename>: Play files according to a playlist file (ASX, Winamp, SMIL, or one-file-per-line format).
NOTE: This option is considered an entry so options found after it will apply only to the elements of this playlist.
FIXME: This needs to be clarified and documented thoroughly.
-rtc-device <device>: Use the specified device for RTC timing.
-shuffle: Play files in random order.
-skin <name> (GUI only): Loads a skin from the directory given as parameter below the default skin directories, /usr/local/share/mplayer/skins/ and ~/.mplayer/skins/.
EXAMPLE:; -skin fittyfene

Tries /usr/local/share/mplayer/skins/fittyfene and afterwards ~/.mplayer/skins/fittyfene.

-slave (also see -input): Switches on slave mode, in which MPlayer works as a backend for other programs. Instead of intercepting keyboard events, MPlayer will read commands separated by a newline (\n) from stdin.
NOTE: See -input cmdlist for a list of slave commands and DOCS/tech/slave.txt for their description.
-softsleep: Time frames by repeatedly checking the current time instead of asking the kernel to wake up MPlayer at the correct time. Useful if your kernel timing is imprecise and you cannot use the RTC either. Comes at the price of higher CPU consumption.
-sstep <sec>: Skip <sec> seconds after every frame. The normal framerate of the movie is kept, so playback is accelerated. Since MPlayer can only seek to the next keyframe this may be inexact.

DEMUXER/STREAM OPTIONS

-a52drc <level>

Select the Dynamic Range Compression level for AC3 audio streams. <level> is a float value ranging from 0 to 1, where 0 means no compression and 1 (which is the default) means full compression (make loud passages more silent and vice versa). This option only shows an effect if the AC3 stream contains the required range compression information.
-aid <ID> (also see -alang): Select audio channel (MPEG: 0-31, AVI/OGM: 1-99, ASF/RM: 0-127, VOB(AC3): 128-159, VOB(LPCM): 160-191, MPEG-TS 17-8190). MPlayer prints the available audio IDs when run in verbose (-v) mode. When playing an MPEG-TS stream, MPlayer/MEncoder will use the first program (if present) with the chosen audio stream.
-alang <language code[,language code,...]> (also see -aid): Specify a priority list of audio languages to use. Different container formats employ different language codes. DVDs use ISO 639-1 two letter language codes, Matroska and NUT use ISO 639-2 three letter language codes while OGM uses a free-form identifier. MPlayer prints the available languages when run in verbose (-v) mode.
EXAMPLE:; mplayer dvd://1 -alang hu,en

Chooses the Hungarian language track on a DVD and falls back on English if Hungarian is not available.

mplayer -alang jpn example.mkv

Plays a Matroska file in Japanese.

-audio-demuxer <[+]name> (-audiofile only): Force audio demuxer type for -audiofile. Use a '+' before the name to force it, this will skip some checks! Give the demuxer name as printed by -audio-demuxer help. For backward compatibility it also accepts the demuxer ID as defined in libmpdemux/demuxer.h. -audio-demuxer audio or -audio-demuxer 17 forces MP3.
-audiofile <filename>: Play audio from an external file (WAV, MP3 or Ogg Vorbis) while viewing a movie.
-audiofile-cache <kBytes>: Enables caching for the stream used by -audiofile, using the specified amount of memory.
-bandwidth <value> (network only): Specify the maximum bandwidth for network streaming (for servers that are able to send content in different bitrates). Useful if you want to watch live streamed media behind a slow connection. With Real RTSP streaming, it is also used to set the maximum delivery bandwidth allowing faster cache filling and stream dumping.
-cache <kBytes>: This option specifies how much memory (in kBytes) to use when precaching a file or URL. Especially useful on slow media.
-nocache: Turns off caching.
-cache-min <percentage>: Playback will start when the cache has been filled up to <percentage> of the total.
-cache-seek-min <percentage>: If a seek is to be made to a position within <percentage> of the cache size from the current position, MPlayer will wait for the cache to be filled to this position rather than performing a stream seek (default: 50).
-cdda <option1:option2> (CDDA only): 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. Values other than 0 seem to break playback of anything but the first track.

0: disable checking (default)
1: overlap checking only
2: full data correction and verification

generic-dev=<value>

Use specified generic SCSI device.

sector-size=<value>

Set 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.

-cdrom-device <path to device>

Specify the CD-ROM device (default: /dev/cdrom).

-channels <number> (also see -af channels)

Request the number of playback channels (default: 2). MPlayer asks the decoder to decode the audio into as many channels as specified. Then it is up to the decoder to fulfill the requirement. 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. To directly control the number of output channels independently of how many channels are decoded, use the channels filter.
NOTE: This option is honored by codecs (AC3 only), filters (surround) and audio output drivers (OSS at least).

Available options are:

stereo

surround

full 5.1

-chapter <chapter ID>[-<endchapter ID>] (DVD only)

Specify which chapter to start playing at. Optionally specify which chapter to end playing at (default: 1).

-cookies (network only)

Send cookies when making HTTP requests.

-cookies-file <filename> (network only)

Read HTTP cookies from <filename> (default: ~/.mozilla/ and ~/.netscape/) and skip reading from default locations. The file is assumed to be in Netscape format.

-delay <sec>

audio delay in seconds (positive or negative float value)
NOTE: When used with MEncoder, this is not guaranteed to work correctly with -ovc copy; use -audio-delay instead.

-ignore-start

Ignore the specified starting time for streams in AVI files. In MPlayer, this nullifies stream delays in files encoded with the -audio-delay option. During encoding, this option prevents MEncoder from transferring original stream start times to the new file; the -audio-delay option is not affected. Note that MEncoder sometimes adjusts stream starting times automatically to compensate for anticipated decoding delays, so don't use this option for encoding without testing it first.

-demuxer <[+]name>

Force demuxer type. Use a '+' before the name to force it, this will skip some checks! Give the demuxer name as printed by -demuxer help. For backward compatibility it also accepts the demuxer ID as defined in libmpdemux/demuxer.h. -demuxer audio or -demuxer 17 forces MP3.

-dumpaudio (MPlayer only)

Dumps raw compressed audio stream to ./stream.dump (useful with MPEG/AC3). If you give more than one of -dumpaudio, -dumpvideo, -dumpstream on the command line only the last one will work.

-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. If you give more than one of -dumpaudio, -dumpvideo, -dumpstream on the command line only the last one will work.

-dumpvideo (MPlayer only)

Dump raw compressed video stream to ./stream.dump (not very usable). If you give more than one of -dumpaudio, -dumpvideo, -dumpstream on the command line only the last one will work.

-dvbin <options> (DVB only)

Pass the following parameters to the DVB input module, in order to override the default ones:

card=<1-4>

Specifies using card number 1-4 (default: 1).

file=<filename>

Instructs MPlayer to read the channels list from <filename>. Default is ~/.mplayer/ channels.conf.{sat,ter,cbl,atsc} (based on your card type) or ~/.mplayer/channels.conf as a last resort.

timeout=<1-30>

Maximum number of seconds to wait when trying to tune a frequency before giving up (default: 30).

-dvd-device <path to device> (DVD only): Specify the DVD device (default: /dev/dvd). You can also specify a directory that contains files previously copied directly from a DVD (with e.g. vobcopy). Note that using -dumpstream is usually a better way to copy DVD titles in the first place (see the examples).
-dvdangle <angle ID> (DVD only): Some DVD discs contain scenes that can be viewed from multiple angles. Here you can tell MPlayer which angles to use (default: 1).
-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 http://www.mplayerhq.hu/DOCS/HTML/en/edl.html for details on how to use this.
-endpos <[[hh:]mm:]ss[.ms]|size[b|kb|mb]> (also see -ss and -sb): Stop at given time or byte position.
NOTE: Byte position is enabled only for MEncoder and will not be accurate, as it can only stop at a frame boundary. When used in conjunction with -ss option, -endpos time will shift forward by seconds specified with -ss.
EXAMPLE:; -endpos 56

Stop at 56 seconds.

-endpos 01:10:00

Stop at 1 hour 10 minutes.

-ss 10 -endpos 56

Stop at 1 minute 6 seconds.

-endpos 100mb

Encode only 100 MB.

-forceidx: Force index rebuilding. Useful for files with broken index (A/V desync, etc). This will enable seeking in files where seeking was not possible. You can fix the index permanently with MEncoder (see the documentation).
NOTE: This option only works if the underlying media supports seeking (i.e. not with stdin, pipe, etc).
-fps <float value>: Override video framerate. Useful if the original value is wrong or missing.
-frames <number>: Play/convert only first <number> frames, then quit.
-hr-mp3-seek (MP3 only): Hi-res MP3 seeking. Enabled when playing from an external MP3 file, as we need to seek to the very exact position to keep A/V sync. Can be slow especially when seeking backwards since it has to rewind to the beginning to find an exact frame position.
-idx (also see -forceidx): Rebuilds index of files if no index was found, allowing seeking. Useful with broken/incomplete downloads, or badly created files.
NOTE: This option only works if the underlying media supports seeking (i.e. not with stdin, pipe, etc).
-ipv4-only-proxy (network only): Skip the proxy for IPv6 addresses. It will still be used for IPv4 connections.
-loadidx <index file>: The file from which to read the video index data saved by -saveidx. This index will be used for seeking, overriding any index data contained in the AVI itself. MPlayer will not prevent you from loading an index file generated from a different AVI, but this is sure to cause unfavorable results.
NOTE: This option is obsolete now that MPlayer has OpenDML support.
-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:; w=<value>

input file width (default: autodetect)

h=<value>

input file height (default: autodetect)

fps=<value>

output fps (default: 25)

type=<value>

input file type (available: jpeg, png, tga, sgi)

-ni (AVI only): Force usage of non-interleaved AVI parser (fixes playback of some bad AVI files).
-nobps (AVI only): Do not use average byte/second value for A-V sync. Helps with some AVI files with broken header.
-noextbased: Disables extension-based demuxer selection. By default, when the 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 the demuxer. Always falls back on content-based demuxer selection.
-passwd <password> (also see -user) (network only): Specify password for HTTP authentication.
-prefer-ipv4 (network only): Use IPv4 on network connections. Falls back on IPv6 automatically.
-prefer-ipv6 (IPv6 network only): Use IPv6 on network connections. Falls back on IPv4 automatically.
-pvr <option1:option2:...> (PVR only): This option tunes various encoding properties of the PVR capture module. It has to be used with any hardware MPEG encoder based card supported by the V4L2 driver. The Hauppauge WinTV PVR-150/250/350/500 and all IVTV based cards are known as PVR capture cards. Be aware that only Linux 2.6.18 kernel and above is able to handle MPEG stream through V4L2 layer. For hardware capture of an MPEG stream and watching it with MPlayer/MEncoder, use 'pvr://' as a movie URL.
Available options are:; aspect=<0-3>

Specify input aspect ratio:

0: 1:1
1: 4:3 (default)
2: 16:9
3: 2.21:1

arate=<32000-48000>

Specify encoding audio rate (default: 48000 Hz, available: 32000, 44100 and 48000 Hz).

amode=<value>

Specify audio encoding mode. Available preset values are 'stereo', 'joint_stereo', 'dual' and 'mono' (default: stereo).

vbitrate=<value>

Specify average video bitrate encoding in Mbps (default: 6).

vmode=<value>

Specify video encoding mode:

vbr: Variable BitRate (default)
cbr: Constant BitRate

vpeak=<value>

Specify peak video bitrate encoding in Mbps (only useful for VBR encoding, default: 9.6).

ps: MPEG-2 Program Stream (default)
ts: MPEG-2 Transport Stream
mpeg1: MPEG-1 System Stream
vcd: Video CD compatible stream
svcd: Super Video CD compatible stream
dvd: DVD compatible stream

-rawaudio <option1:option2:...>: This option lets you play raw audio files. You have to use -demuxer rawaudio as well. It may also be used to play audio CDs which are not 44kHz 16-bit stereo. For playing raw AC3 streams use -rawaudio format=0x2000 -demuxer rawaudio.
Available options are:; channels=<value>

number of channels

rate=<value>

rate in samples per second

samplesize=<value>

sample size in bytes

bitrate=<value>

bitrate for rawaudio files

Play the famous "foreman" sample video.

mplayer sample-720x576.yuv -demuxer rawvideo -rawvideo w=720:h=576

Play a raw YUV sample.

-rtsp-port: Used with 'rtsp://' URLs to force the client's port number. This option may be useful if you are behind a router and want to forward the RTSP stream from the server to a specific client.
-rtsp-destination: Used with 'rtsp://' URLs to force the destination IP address to be bound. This option may be useful with some RTSP server which do not send RTP packets to the right interface. If the connection to the RTSP server fails, use -v to see which IP address MPlayer tries to bind to and try to force it to one assigned to your computer instead.
-rtsp-stream-over-tcp (LIVE555 only): 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.live555.com/mplayer/).
-saveidx <filename>: Force index rebuilding and dump the index to <filename>. Currently this only works with AVI files.
NOTE: This option is obsolete now that MPlayer has OpenDML support.
-sb <byte position> (also see -ss): Seek to byte position. Useful for playback from CD-ROM images or VOB files with junk at the beginning.
-speed <0.01-100>: Slow down or speed up playback by the factor given as parameter. Not guaranteed to work correctly with -oac copy.
-srate <Hz>: Selects the output sample rate to be used (of course sound cards have limits on this). If the sample frequency selected is different from that of the current media, the resample or lavcresample audio filter will be inserted into the audio filter layer to compensate for the difference. The type of resampling can be controlled by the -af-adv option. The default is fast resampling that may cause distortion.
-ss <time> (also see -sb): Seek to given time position.
EXAMPLE:; -ss 56

Seeks to 56 seconds.

-ss 01:10:00

Seeks to 1 hour 10 min.

-tskeepbroken: Tells MPlayer not to discard TS packets reported as broken in the stream. Sometimes needed to play corrupted MPEG-TS files.
-tsprobe <byte position>: When playing an MPEG-TS stream, this option lets you specify how many bytes in the stream you want MPlayer to search for the desired audio and video IDs.
-tsprog <1-65534>: When playing an MPEG-TS stream, you can specify with this option which program (if present) you want to play. Can be used with -vid and -aid.
-radio <option1:option2:...> (radio only): These options set various parameters of the radio capture module. For listening to radio with MPlayer use 'radio://<frequency>' (if channels option is not given) or 'radio://<channel_number>' (if channels option is given) as a movie URL. To start the grabbing subsystem, use 'radio://<frequency or channel>/capture'. If the capture keyword is not given you can listen to radio using the line-in cable only. Using capture to listen is not recommended due to synchronization problems, which makes this process uncomfortable.
Available options are:; device=<value>

Radio device to use (default: /dev/radio0).

driver=<value>

Radio driver to use (default: v4l2 if available, otherwise v4l). Currently, v4l and v4l2 drivers are supported.

volume=<0..100>

sound volume for radio device (default 100)

channels=<frequency>-<name>,<frequency>-<name>,...

Set channel list. Use _ for spaces in names (or play with quoting ;-). The channel names will then be written using OSD and the slave commands radio_step_channel and radio_set_channel will be usable for a remote control (see LIRC). If given, number in movie URL will be treated as channel position in channel list.
EXAMPLE: radio://1, radio://104.4, radio_set_channel 1

adevice=<value>

Name of device to capture sound from. Without such a name capture will be disabled, even if the capture keyword appears in the URL. For ALSA devices use it in the form hw=<card>.<device>. If the device name contains a '=', the module will use ALSA to capture, otherwise OSS.

arate=<value>

Rate in samples per second (default: 44100).
NOTE: When using audio capture set also -rawaudio rate=<value> option with the same value as arate. If you have problems with sound speed (runs too quickly), try to play with different rate values (e.g. 48000,44100,32000,...).

achannels=<value>

Number of audio channels to capture.

-tv <option1:option2:...> (TV/PVR only): This option tunes various properties of the TV capture module. For watching TV with MPlayer, use 'tv://' or 'tv://<channel_number>' or even 'tv://<channel_name> (see option channels for channel_name below) as a movie URL.
Available options are:; noaudio

no sound

driver=<value>

available: dummy, v4l, v4l2, bsdbt848

device=<value>

Specify TV device (default: /dev/video0).

input=<value>

Specify input (default: 0 (TV), see console output for available inputs).

freq=<value>

Specify the frequency to set the tuner to (e.g. 511.250). Not compatible with the channels parameter.

outfmt=<value>

Specify the output format of the tuner with a preset value supported by the V4L driver (yv12, rgb32, rgb24, rgb16, rgb15, uyvy, yuy2, i420) or an arbitrary format given as hex value. Try outfmt=help for a list of all available formats.

width=<value>

output window width

height=<value>

output window height

fps=<value>

framerate at which to capture video (frames per second)

buffersize=<value>

maximum size of the capture buffer in megabytes (default: dynamical)

norm=<value>

For bsdbt848 and v4l, PAL, SECAM, NTSC are available. For v4l2, see the console output for a list of all available norms, also see the normid option below.

normid=<value> (v4l2 only)

Sets the TV norm to the given numeric ID. The TV norm depends on the capture card. See the console output for a list of available TV norms.

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 slave commands tv_step_channel, tv_set_channel and tv_last_channel will be usable for a remote control (see LIRC). Not compatible with the frequency parameter.
NOTE: The channel number will then be the position in the 'channels' list, beginning with 1.
EXAMPLE: tv://1, tv://TV1, tv_set_channel 1, tv_set_channel TV1

[brightness|contrast|hue|saturation]=<-100-100>

Set the image equalizer on the card.

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 forcing 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. <value> should be /dev/xxx for OSS and a hardware ID for ALSA. You must replace any ':' by a '.' in the hardware ID for ALSA.

audioid=<value>

Choose an audio output of the capture card, if it has more than one.

[volume|bass|treble|balance]=<0-65535> (v4l1)

[volume|bass|treble|balance]=<0-100> (v4l2)

These options set parameters of the mixer on the video capture card. They will have no effect, if your card does not have one. For v4l2 50 maps to the default value of the control, as reported by the driver.

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 sound card.

mjpeg

Use hardware MJPEG compression (if the card supports it). When using this option, you do not need to specify the width and height of the output window, because MPlayer will determine it automatically from the decimation value (see below).

decimation=<1|2|4>

choose the size of the picture that will be compressed by hardware MJPEG compression:

1: full size 704x576 PAL 704x480 NTSC
2: medium size 352x288 PAL 352x240 NTSC
4: small size 176x144 PAL 176x120 NTSC

-user-agent <string>: Use <string> as user agent for HTTP streaming.
-vid <ID>: Select video channel (MPG: 0-15, ASF: 0-255, MPEG-TS: 17-8190). When playing an MPEG-TS stream, MPlayer/MEncoder will use the first program (if present) with the chosen video stream.
-vivo <sub-options> (DEBUG CODE): Force audio parameters for the VIVO demuxer (for debugging purposes).

OSD/SUBTITLE OPTIONS

NOTE: Also see -vf expand.

-dumpsrtsub (MPlayer only)

Convert the given subtitle (specified with the -sub option) to the time-based SubViewer (SRT) subtitle format. Creates a dumpsub.srt file in the current directory.
NOTE: Some broken hardware players choke on SRT subtitle files with Unix line endings. If you are unlucky enough to have such a box, pass your subtitle files through unix2dos or a similar program to replace Unix line endings with DOS/Windows line endings.

-dumpsub (MPlayer only) (BETA CODE)

Dumps the subtitle substream from VOB streams. Also see the -dump*sub and -vobsubout* options.

-embeddedfonts (FreeType only)

-sid <ID> (also see -slang, -vobsubid)

Display the subtitle stream specified by <ID> (0-31). MPlayer prints the available subtitle IDs when run in verbose (-v) mode. If you cannot select one of the subtitles on a DVD, also try -vobsubid.

-slang <language code[,language code,...]> (also see -sid)

Specify a priority list of subtitle languages to use. Different container formats employ different language codes. DVDs use ISO 639-1 two letter language codes, Matroska uses ISO 639-2 three letter language codes while OGM uses a free-form identifier. MPlayer prints the available languages when run in verbose (-v) mode.

EXAMPLE:

mplayer dvd://1 -slang hu,en

Chooses the Hungarian subtitle track on a DVD and falls back on English if Hungarian is not available.

mplayer -slang jpn example.mkv

Plays a Matroska file with Japanese subtitles.

-spuaa <mode> (OSD only)

Antialiasing/scaling mode for DVD/VOBsub. A value of 16 may be added to <mode> in order to force scaling even when original and scaled frame size already match. This can be employed to e.g. smooth subtitles with gaussian blur. Available modes are:

Specify the alpha channel value for subtitles and OSD backgrounds. Big values mean more transparency. 0 means completely transparent.

-sub-bg-color <0-255>

Specify the color value for subtitles and OSD backgrounds. Currently subtitles are grayscale so this value is equivalent to the intensity of the color. 255 means white and 0 black.

-sub-demuxer <[+]name> (-subfile only) (BETA CODE)

Force subtitle demuxer type for -subfile. Use a '+' before the name to force it, this will skip some checks! Give the demuxer name as printed by -sub-demuxer help. For backward compatibility it also accepts the demuxer ID as defined in libmpdemux/demuxer.h.

-sub-fuzziness <mode>

Adjust matching fuzziness when searching for subtitles:

exact match

Specify which edge of the subtitles should be aligned at the height given by -subpos.

Align subtitle top edge (original behavior).

Align subtitle center.

Align subtitle bottom edge (default).

-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.

-subcp <codepage> (iconv only)

If your system supports iconv(3), you can use this option to specify the subtitle codepage.

EXAMPLE:

-subcp latin2
-subcp cp1250

-subcp enca:<language>:<fallback codepage> (ENCA only)

You can specify your language using a two letter language code to make ENCA detect the codepage automatically. If unsure, enter anything and watch mplayer -v output for available languages. Fallback codepage specifies the codepage to use, when autodetection fails.

EXAMPLE:

-subcp enca:cs:latin2

Guess the encoding, assuming the subtitles are Czech, fall back on latin 2, if the detection fails.

-subcp enca:pl:cp1250

Guess the encoding for Polish, fall back on cp1250.

-subdelay <sec>

Delays subtitles by <sec> seconds. Can be negative.

-subfile <filename> (BETA CODE)

Currently useless. Same as -audiofile, but for subtitle streams (OggDS?).

-subfont-autoscale <0-3> (FreeType only)

Sets the autoscale mode.
NOTE: 0 means that text scale and OSD scale are font heights in points.

The mode can be:

no autoscale

proportional to movie height

Specify the position of subtitles on the screen. The value is the vertical position of the subtitle in % of the screen height.

-subwidth <10-100> (OSD only)

Specify the maximum width of subtitles on the screen. Useful for TV-out. The value is the width of the subtitle in % of the screen width.

-noterm-osd

Disable the display of OSD messages on the console when no video output is available.

-term-osd-esc <escape sequence>

Specify the escape sequence to use before writing an OSD message on the console. The escape sequence should move the pointer to the beginning of the line used for the OSD and clear it (default: ^[[A\r^[[K).

-unicode

Tells MPlayer to handle the subtitle file as unicode.

-utf8

Tells MPlayer to handle the subtitle file as UTF-8.

Specify the VOBsub subtitle ID.

AUDIO OUTPUT OPTIONS (MPLAYER ONLY)

-abs <value> (-ao oss only) (OBSOLETE)

Override audio driver/card buffer size detection.
-format <format> (also see the format audio filter): Select the sample format used for output from the audio filter layer to the sound card. The values that <format> can adopt are listed below in the description of the format audio filter.
-mixer <device>: Use a mixer device different from the default /dev/mixer. For ALSA this is the mixer name.
-mixer-channel <mixer line>[,mixer index] (-ao oss and -ao alsa only): This option will tell MPlayer to use a different channel for controlling volume than the default PCM. Options for OSS include vol, pcm, line. For a complete list of options look for SOUND_DEVICE_NAMES in /usr/include/linux/soundcard.h. For ALSA you can use the names e.g. alsamixer displays, like Master, Line, PCM.
NOTE: ALSA mixer channel names followed by a number must be specified in the <name,number> format, i.e. a channel labeled 'PCM 1' in alsamixer must be converted to PCM,1.
-softvol: Force the use of the software mixer, instead of using the sound card mixer.
-softvol-max <10.0-10000.0>: Set the maximum amplification level in percent (default: 110). A value of 200 will allow you to adjust the volume up to a maximum of double the current level. With values below 100 the initial volume (which is 100%) will be above the maximum, which e.g. the OSD cannot display correctly.
-volstep <0-100>: Set the step size of mixer volume changes in percent of the whole range (default: 3).

AUDIO OUTPUT DRIVERS (MPLAYER ONLY)

Audio output drivers are interfaces to different audio output facilities. The syntax is:

-ao <driver1[:suboption1[=value]:...],driver2,...[,]>: Specify a priority list of audio output drivers to be used.
If the list has a trailing ',' MPlayer will fall back on drivers not contained in the list. Suboptions are optional and can mostly be omitted. NOTE: See -ao help for a list of compiled-in audio output drivers. EXAMPLE:: -ao alsa,oss,

Try the ALSA driver, then the OSS driver, then others.

-ao alsa:noblock:device=hw=0.3

Sets noblock-mode and the device-name as first card, fourth device.

Available audio output drivers are:
alsa: ALSA 0.9/1.x audio output driver; noblock

Sets noblock-mode.

device=<device>

Sets the device name. Replace any ',' with '.' and any ':' with '=' in the ALSA device name. For hwac3 output via S/PDIF, use an "iec958" or "spdif" device, unless you really know how to set it correctly.

alsa5: ALSA 0.5 audio output driver
oss: OSS audio output driver; <dsp-device>

Sets the audio output device (default: /dev/dsp).

<mixer-device>

Sets the audio mixer device (default: /dev/mixer).

Fixes fullscreen switching on OpenBox 1.x.

-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-left of the screen to the top-left 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 X11 -geometry option format. If an external window is specified using the -wid option, then the x and y coordinates are relative to the top-left corner of the window rather than the screen.
NOTE: This option is only supported by the x11, xmga, xv, xvmc, xvidix, gl, gl2, directx and tdfxfb video output drivers.
EXAMPLE:; 50:40

Places the window at x=50, y=40.

50%:50%

Places the window in the middle of the screen.

100%

Places the window at the middle of the right edge of the screen.

100%:100%

Places the window at the bottom right corner of the screen.

-guiwid <window ID> (also see -wid) (GUI only): This tells the GUI to also use an X11 window and stick itself to the bottom of the video, which is useful to embed a mini-GUI in a browser (with the MPlayer plugin for instance).
-hue <-100-100>: Adjust the hue of the video signal (default: 0). You can get a colored negative of the image with this option. Not supported by all video output drivers.
-monitor-dotclock <range[,range,...]> (-vo fbdev and vesa only): Specify the dotclock or pixelclock range of the monitor.
-monitor-hfreq <range[,range,...]> (-vo fbdev and vesa only): Specify the horizontal frequency range of the monitor.
-monitor-vfreq <range[,range,...]> (-vo fbdev and vesa only): Specify the vertical frequency range of the monitor.
-monitoraspect <ratio> (also see -aspect): Set the aspect ratio of your monitor or TV screen.

-monitoraspect 16:9 or 1.7777
-monitorpixelaspect <ratio> (also see -aspect): Set the aspect of a single pixel of your monitor or TV screen (default: disabled). Overrides the -monitoraspect setting. A value of 0 disables, a value of 1 means square pixels (correct for (almost?) all LCDs).
-nodouble: Disables double buffering, mostly for debugging purposes. Double buffering fixes flicker by storing two frames in memory, and displaying one while decoding another. It can affect OSD negatively, but often removes OSD flickering.
-nograbpointer: Do not grab the mouse pointer after a video mode change (-vm). Useful for multihead setups.
-nokeepaspect: Do not keep window aspect ratio when resizing windows. Only works with the x11, xv, xmga, xvidix, directx video output drivers. Furthermore under X11 your window manager has to honor window aspect hints.
-ontop: Makes the player window stay on top of other windows. Supported by video output drivers which use X11, except SDL, as well as directx, macosx, quartz, ggi and gl2.
-panscan <0.0-1.0>: Enables pan-and-scan functionality (cropping the sides of e.g. a 16:9 movie to make it fit a 4:3 display without black bands). The range controls how much of the image is cropped. Only works with the xv, xmga, mga, gl, gl2, quartz, macosx and xvidix video output drivers.
-panscanrange <-19.0-99.0> (experimental): Change the range of the pan-and-scan functionality (default: 1). Positive values mean multiples of the default range. Negative numbers mean you can zoom in up to a factor of -panscanrange+1. E.g. -panscanrange -3 allows a zoom factor of up to 4. This feature is experimental. Do not report bugs unless you are using -vo gl.
-refreshrate <Hz>: Set the monitor refreshrate in Hz. Currently only supported by -vo directx combined with the -vm option.
-rootwin: Play movie in the root window (desktop background). Desktop background images may cover the movie window, though. Only works with the x11, xv, xmga, xvidix, quartz, macosx and directx video output drivers.
-saturation <-100-100>: Adjust the saturation of the video signal (default: 0). You can get grayscale output with this option. Not supported by all video output drivers.
-screenh <pixels>: Specify the vertical screen resolution for video output drivers which do not know the screen resolution like fbdev, x11 and TVout.
-screenw <pixels>: Specify the horizontal screen resolution for video output drivers which do not know the screen resolution like fbdev, x11 and TVout.
-stop-xscreensaver (X11 only): Turns off xscreensaver at startup and turns it on again on exit.
-vm: Try to change to a different video mode. Supported by the dga, x11, xv, sdl and directx video output drivers. If used with the directx video output driver the -screenw, -screenh, -bpp and -refreshrate options can be used to set the new display mode.
-vsync: Enables VBI for the vesa, dfbmga and svga video output drivers.
-wid <window ID> (also see -guiwid) (X11, OpenGL and DirectX only): This tells MPlayer to attach to an existing window. Useful to embed MPlayer in a browser (e.g. the plugger extension).
-xineramascreen <-2-...> (X11 only): In Xinerama configurations (i.e. a single desktop that spans across multiple displays) this option tells MPlayer which screen to display the movie on. A value of -2 means fullscreen across the whole virtual display, -1 means fullscreen on the display the window currently is on. The initial position set via the -geometry option is relative to the specified screen. Will usually only work with "-fstype -fullscreen" or "-fstype none".
-zrbw (-vo zr only): Display in black and white. For optimal performance, this can be combined with '-lavdopts gray'.
-zrcrop <[width]x[height]+[x offset]+[y offset]> (-vo zr only): Select a part of the input image to display, multiple occurrences of this option switch on cinerama mode. In cinerama mode the movie is distributed over more than one TV (or beamer) to create a larger image. 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 the zr video output driver takes the first v4l device it can find.
-zrfd (-vo zr only): Force decimation: Decimation, as specified by -zrhdec and -zrvdec, only happens if the hardware scaler can stretch the image to its original size. Use this option to force decimation.
-zrhdec <1|2|4> (-vo zr only): Horizontal decimation: Ask the driver to send only every 2nd or 4th line/pixel of the input image to the MJPEG card and use the scaler of the MJPEG card to stretch the image to its original size.
-zrhelp (-vo zr only): Display a list of all -zr* options, their default values and a cinerama mode example.
-zrnorm <norm> (-vo zr only): Specify the TV norm as PAL or NTSC (default: no change).
-zrquality <1-20> (-vo zr only): A number from 1 (best) to 20 (worst) representing the JPEG encoding quality.
-zrvdec <1|2|4> (-vo zr only): Vertical decimation: Ask the driver to send only every 2nd or 4th line/pixel of the input image to the MJPEG card and use the scaler of the MJPEG card to stretch the image to its original size.
-zrxdoff <x display offset> (-vo zr only): If the movie is smaller than the TV screen, this option specifies the x offset from the upper-left corner of the TV screen (default: centered).
-zrydoff <y display offset> (-vo zr only): If the movie is smaller than the TV screen, this option specifies the y offset from the upper-left corner of the TV screen (default: centered).

VIDEO OUTPUT DRIVERS (MPLAYER ONLY)

Video output drivers are interfaces to different video output facilities. The syntax is:

-vo <driver1[:suboption1[=value]:...],driver2,...[,]>: Specify a priority list of video output drivers to be used.
If the list has a trailing ',' MPlayer will fall back on drivers not contained in the list. Suboptions are optional and can mostly be omitted. NOTE: See -vo help for a list of compiled-in video output drivers. EXAMPLE:: -vo xmga,xv,

Try the Matrox X11 driver, then the Xv driver, then others.

-vo directx:noaccel

Uses the DirectX driver with acceleration features turned off.

Available video output drivers are:
xv (X11 only): Uses the XVideo extension of XFree86 4.x to enable hardware accelerated playback. If you cannot use a hardware specific driver, this is probably the best option. For information about what colorkey is used and how it is drawn run MPlayer with -v option and look out for the lines tagged with [xv common] at the beginning.; port=<number>

Select a specific XVideo port.

ck=<cur|use|set>

Select the source from which the colorkey is taken (default: cur).

cur

The default takes the colorkey currently set in Xv.

use

Use but do not set the colorkey from MPlayer (use -colorkey option to change it).

set

Same as use but also sets the supplied colorkey.

ck-method=<man|bg|auto>

Sets the colorkey drawing method (default: man).

man

Draw the colorkey manually (reduces flicker in some cases).

Set the colorkey as window background.

auto

Let Xv draw the colorkey.

x11 (X11 only): Shared memory video output driver without hardware acceleration that works whenever X11 is present.
xover (X11 only): Adds X11 support to all overlay based video output drivers. Currently only supported by tdfx_vid.; <vo_driver>

Select the driver to use as source to overlay on top of X11.

xvmc (X11 with -vc ffmpeg12mc only): Video output driver that uses the XvMC (X Video Motion Compensation) extension of XFree86 4.x to speed up MPEG-1/2 and VCR2 decoding.; port=<number>

Select a specific XVideo port.

(no)benchmark

Disables image display. Necessary for proper benchmarking of drivers that change image buffers on monitor retrace only (nVidia). Default is not to disable image display (nobenchmark).

(no)bobdeint

Very simple deinterlacer. Might not look better than -vf tfields=1, but it is the only deinterlacer for xvmc (default: nobobdeint).

(no)queue

Queue frames for display to allow more parallel work of the video hardware. May add a small (not noticeable) constant A/V desync (default: noqueue).

(no)sleep

Use sleep function while waiting for rendering to finish (not recommended on Linux) (default: nosleep).

ck=cur|use|set

Same as -vo xv:ck (see -vo xv).

ck-method=man|bg|auto

Same as -vo xv:ck-method (see -vo xv).

dga (X11 only): Play video through the XFree86 Direct Graphics Access extension. Considered obsolete.
sdl (SDL only): Highly platform independent SDL (Simple Directmedia Layer) library video output driver. Since SDL uses its own X11 layer, MPlayer X11 options do not have any effect on SDL.; driver=<driver>

Explicitly choose the SDL driver to use.

(no)forcexv

Use XVideo through the sdl video output driver (default: forcexv).

(no)hwaccel

Use hardware accelerated scaler (default: hwaccel).

vidix: VIDIX (VIDeo Interface for *niX) is an interface to the video acceleration features of different graphics cards. Very fast video output driver on cards that support it.; <subdevice>

Explicitly choose the VIDIX subdevice driver to use. Available subdevice drivers are cyberblade_vid.so, mach64_vid.so, mga_crtc2_vid.so, mga_vid.so, nvidia_vid.so, pm3_vid.so, radeon_vid.so, rage128_vid.so, sis_vid.so and unichrome_vid.so.

xvidix (X11 only): X11 frontend for VIDIX; <subdevice>

same as vidix

cvidix: Generic and platform independent VIDIX frontend, can even run in a text console with nVidia cards.; <subdevice>

same as vidix

winvidix (Windows only): Windows frontend for VIDIX; <subdevice>

same as vidix

directx (Windows only): Video output driver that uses the DirectX interface.; noaccel

Turns off hardware acceleration. Try this option if you have display problems.

quartz (Mac OS X only): Mac OS X Quartz video output driver. Under some circumstances, it might be more efficient to force a packed YUV output format, with e.g. -vf format=yuy2.; device_id=<number>

Choose the display device to use in fullscreen.

Specify the fullscreen resolution (useful on slow systems).

macosx (Mac OS X 10.4 or 10.3.9 with QuickTime 7): Mac OS X CoreVideo video output driver; device_id=<number>

Choose the display device to use in fullscreen.

fbdev (Linux only): Uses the kernel framebuffer to play video.; <device>

bbosd

Draw OSD into black bands below the movie (slower).

native

Use only native drawing functions. This avoids direct rendering, OSD and hardware acceleration.

retrace

Force frame switch on vertical retrace. Usable only with -double. It has the same effect as the -vsync option.

Try to select a video mode with square pixels.

vidix

Use svga with VIDIX.

gl: OpenGL video output driver, simple version. Video size must be smaller than the maximum texture size of your OpenGL implementation. Intended to work even with the most basic OpenGL implementations, but also makes use of newer extensions, which allow support for more colorspaces and direct rendering. Please use -dr if it works with your OpenGL implementation, since for higher resolutions this provides a big speedup. The code performs very few checks, so if a feature does not work, this might be because it is not supported by your card/OpenGL implementation even if you do not get any error message. Use glxinfo or a similar tool to display the supported OpenGL extensions.; (no)manyfmts

Enables support for more (RGB and BGR) color formats (default: enabled). Needs OpenGL version >= 1.2.

slice-height=<0-...>

Number of lines copied to texture in one piece (default: 4). 0 for whole image.
NOTE: If YUV colorspace is used (see yuv suboption), special rules apply:

If the decoder uses slice rendering (see -noslices), this setting has no effect, the size of the slices as provided by the decoder is used.
If the decoder does not use slice rendering, the default is 16.

(no)osd

Enable or disable support for OSD rendering via OpenGL (default: enabled). This option is for testing; to disable the OSD use -osdlevel 0 instead.

(no)scaled-osd

Changes the way the OSD behaves when the size of the window changes (default: disabled). When enabled behaves more like the other video output drivers, which is better for fixed-size fonts. Disabled looks much better with FreeType fonts and uses the borders in fullscreen mode.

osdcolor=<0xRRGGBB>

Color for OSD (default: 0xffffff, corresponds to white).

(no)aspect

Enable or disable aspect scaling and pan-and-scan support (default: enabled). Disabling might increase speed.

rectangle=<0,1,2>

Select usage of rectangular textures which saves video RAM, but often is slower (default: 0).

0: Use power-of-two textures (default).
1: Use the GL_ARB_texture_rectangle extension.
2: Use the GL_ARB_texture_non_power_of_two extension. In some cases only supported in software and thus very slow.

(no)glfinish

Call glFinish() before swapping buffers. Slower but in some cases more correct output (default: disabled).

swapinterval=<n>

Minimum interval between two buffer swaps, counted in displayed frames (default: 1). 1 is equivalent to enabling VSYNC, 0 to disabling VSYNC. Values below 0 will leave it at the system default. This limits the framerate to (horizontal refresh rate / n). Requires GLX_SGI_swap_control support to work. With some (most/all?) implementations this only works in fullscreen mode.

yuv=<n>

Select the type of YUV to RGB conversion.

0: Use software conversion (default). Compatible with all OpenGL versions. Provides brightness, contrast and saturation control.
1: Use register combiners. This uses an nVidia-specific extension (GL_NV_register_combiners). At least three texture units are needed. Provides saturation and hue control. This method is fast but inexact.
2: Use a fragment program. Needs the GL_ARB_fragment_program extension and at least three texture units. Provides brightness, contrast, saturation and hue control.
3: Use a fragment program using the POW instruction. Needs the GL_ARB_fragment_program extension and at least three texture units. Provides brightness, contrast, saturation, hue and gamma control. Gamma can also be set independently for red, green and blue. Method 4 is usually faster.
4: Use a fragment program with additional lookup. Needs the GL_ARB_fragment_program extension and at least four texture units. Provides brightness, contrast, saturation, hue and gamma control. Gamma can also be set independently for red, green and blue.
5: Use ATI-specific method (for older cards). This uses an ATI-specific extension (GL_ATI_fragment_shader - not GL_ARB_fragment_shader!). At least three texture units are needed. Provides saturation and hue control. This method is fast but inexact.
6: Use a 3D texture to do conversion via lookup. Needs the GL_ARB_fragment_program extension and at least four texture units. Extremely slow (software emulation) on some (all?) ATI cards since it uses a texture with border pixels. Provides brightness, contrast, saturation, hue and gamma control. Gamma can also be set independently for red, green and blue. Speed depends more on GPU memory bandwidth than other methods.

lscale=<n>

Select the scaling function to use for luminance scaling. Only valid for yuv modes 2, 3, 4 and 6.

0: Use simple linear filtering (default).
1: Use bicubic filtering (better quality). Needs one additional texture unit. Older cards will not be able to handle this for chroma at least in fullscreen mode.

cscale=<n>

Select the scaling function to use for chrominance scaling. For details see lscale.

customprog=<filename>

Load a custom fragment program from <filename>. See TOOLS/edgedect.fp for an example.

customtex=<filename>

Load a custom "gamma ramp" texture from <filename>. This can be used in combination with yuv=4 or with the customprog option.

(no)customtlin

If enabled (default) use GL_LINEAR interpolation, otherwise use GL_NEAREST for customtex texture.

(no)customtrect

If enabled, use texture_rectangle for customtex texture. Default is disabled.

gl2: OpenGL video output driver, second generation. Supports OSD and videos larger than the maximum texture size.; (no)glfinish

same as gl (default: enabled)

yuv=<n>

Select the type of YUV to RGB conversion. If set to anything except 0 OSD will be disabled and brightness, contrast and gamma setting is only available via the global X server settings. Apart from this the values have the same meaning as for -vo gl.

null: Produces no video output. Useful for benchmarking.
aa: ASCII art video output driver that works on a text console. You can get a list and an explanation of available suboptions executing mplayer -vo aa:help
caca: Color ASCII art video output driver that works on a text console.
bl: Video playback using the Blinkenlights UDP protocol. This driver is highly hardware specific.; <subdevice>

Explicitly choose the Blinkenlights subdevice driver to use. It is something like arcade:host=localhost:2323 or hdl:file=name1,file=name2. You must specify a subdevice.

ggi: GGI graphics system video output driver; <driver>

Explicitly choose the GGI driver to use. Replace any ',' that would appear in the driver string by a '.'.

directfb: Play video using the DirectFB library.; (no)input

Use the DirectFB instead of the MPlayer keyboard code (default: enabled).

buffermode=single|double|triple

Double and triple buffering give best results if you want to avoid tearing issues. Triple buffering is more efficient than double buffering as it does not block MPlayer while waiting for the vertical retrace. Single buffering should be avoided (default: single).

fieldparity=top|bottom

Control the output order for interlaced frames (default: disabled). Valid values are top = top fields first, bottom = bottom fields first. This option does not have any effect on progressive film material like most MPEG movies are. You need to enable this option if you have tearing issues or unsmooth motions watching interlaced film material.

layer=N

Will force layer with ID N for playback (default: -1 - auto).

dfbopts=<list>

Specify a parameter list for DirectFB.

dfbmga: Matrox G400/G450/G550 specific video output driver that uses the DirectFB library to make use of special hardware features. Enables CRTC2 (second head), displaying video independently of the first head.; (no)input

same as directfb (default: disabled)

buffermode=single|double|triple

same as directfb (default: triple)

fieldparity=top|bottom

same as directfb

(no)bes

Enable the use of the Matrox BES (backend scaler) (default: disabled). Gives very good results concerning speed and output quality as interpolated picture processing is done in hardware. Works only on the primary head.

(no)spic

Make use of the Matrox sub picture layer to display the OSD (default: enabled).

(no)crtc2

Turn on TV-out on the second head (default: enabled). The output quality is amazing as it is a full interlaced picture with proper sync to every odd/even field.

tvnorm=pal|ntsc|auto

Will set the TV norm of the Matrox card without the need for modifying /etc/directfbrc (default: disabled). Valid norms are pal = PAL, ntsc = NTSC. Special norm is auto (auto-adjust using PAL/NTSC) because it decides which norm to use by looking at the framerate of the movie.

mga (Linux only): Matrox specific video output driver that makes use of the YUV back end scaler on Gxxx cards through a kernel module. If you have a Matrox card, this is the fastest option.; <device>

Explicitly choose the Matrox device name to use (default: /dev/mga_vid).

xmga (Linux, X11 only): The mga video output driver, running in an X11 window.; <device>

Explicitly choose the Matrox device name to use (default: /dev/mga_vid).

syncfb: Video output driver for the SyncFB kernel module, which provides special hardware features of Matrox Gxxx cards like hardware deinterlacing, scaling and synchronizing your video output to the vertical retrace of your monitor.
3dfx (Linux only): 3dfx specific video output driver. This driver directly uses the 3dfx hardware on top of X11. Only 16 bpp are supported. FIXME: It' ok the difference between 3dfx, tdfxfb and tdfx_vid?

DECODING/FILTERING OPTIONS

-ac <[-|+]codec1,[-|+]codec2,...[,]>

Specify a priority list of audio codecs to be used, according to their codec name in codecs.conf. Use a '-' before the codec name to omit it.

4: bitstream
8: macroblock (MB) type
16: per-block quantization parameter (QP)
32: motion vector
0x0040: motion vector visualization (use -noslices)

2: iterative motion vector (MV) search (slow)
3: all (default)

er=<value>

Set error resilience strategy.

0: disabled

2: normal (default) (Works with compliant encoders.)
3: aggressive (More checks, but might cause problems even for valid bitstreams.)
4: very aggressive

fast (MPEG-2 only)

gray

grayscale only decoding (a bit faster than with color)

idct=<0-99> (see -lavcopts)

For best decoding quality use the same IDCT algorithm for decoding and encoding. This may come at a price in accuracy, though.

lowres=<number>[,<w>]

Decode at lower resolutions. Low resolution decoding is not supported by all codecs, and it will often result in ugly artifacts. This is not a bug, but a side effect of not decoding at full resolution.

0: disabled

3: 1/8 resolution

If <w> is specified lowres decoding will be used only if the width of the video is major than or equal to <w>.

Skip the given number of macroblock rows at the bottom.

st=<number> (MPEG-2 only)

Skip the given number of macroblock rows at the top.

skiploopfilter=<skipvalue>

Skips the loop filter (AKA deblocking) during H.264 decoding. Since the filtered frame is supposed to be used as reference for decoding dependent frames this has a worse effect on quality than not doing deblocking on e.g. MPEG-2 video. But at least for high bitrate HDTV this provides a big speedup with no visible quality loss.

<skipvalue> can be either one of the following:

none: Never skip.
default: Skip useless processing steps (e.g. 0 size packets in AVI).
nonref: Skip frames that are not referenced (i.e. not used for decoding other frames, the error cannot "build up").
bidir: Skip B-Frames.
nonkey: Skip all frames except keyframes.
all: Skip all frames.

skipidct=<skipvalue>

Skips the IDCT step. This degrades quality a lot of in almost all cases (see skiploopfilter for available skip values).

skipframe=<skipvalue>

Skips decoding of frames completely. Big speedup, but jerky motion and sometimes bad artifacts (see skiploopfilter for available skip values).

threads=<1-8>

number of threads to use for decoding (default: 1)

vismv=<value>

Visualize motion vectors.

0: disabled
1: Visualize forward predicted MVs of P-frames.

4: Visualize backward predicted MVs of B-frames.

vstats

Prints some statistics and stores them in ./vstats_*.log.

-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 video card and available cache. It has effect only with libmpeg2 and libavcodec codecs.
-nosound: Do not play/encode sound. Useful for benchmarking.
-novideo: Do not play/encode video. In many cases this will not work, use -vc null -vo null instead.
-pp <quality> (also see -vf pp): Set the DLL postprocess level. This option is no longer usable with -vf pp. It only works with Win32 DirectShow DLLs with internal postprocessing routines. The valid range of -pp values varies by codec, it is mostly 0-6, where 0=disable, 6=slowest/best.
-pphelp (also see -vf pp): Show a summary about the available postprocess filters and their usage.
-ssf <mode>: Specifies software scaler parameters.
EXAMPLE:; -vf scale -ssf lgb=3.0; lgb=<0-100>

gaussian blur filter (luma)

Select type of MP2/MP3 stereo output.

stereo

left channel

right channel

-sws <software scaler type> (also see -vf scale and -zoom)

Specify the software scaler algorithm to be used with the -zoom option. This affects video output drivers which lack hardware acceleration, e.g. x11.

Available types are:

fast bilinear

bilinear

experimental

nearest neighbor (bad quality)

area

luma bicubic / chroma bilinear

gauss

sincR

lanczos

natural bicubic spline

NOTE: Some -sws options are tunable. The description of the scale video filter has further information.

-vc <[-|+]codec1,[-|+]codec2,...[,]>

Specify a priority list of video codecs to be used, according to their codec name in codecs.conf. Use a '-' before the codec name to omit it. Use a '+' before the codec name to force it, this will likely crash! If the list has a trailing ',' MPlayer will fall back on codecs not contained in the list.
NOTE: See -vc help for a full list of available codecs.

EXAMPLE:

-vc divx

Force Win32/VfW DivX codec, no fallback.

-vc -divxds,-divx,

Skip Win32 DivX codecs.

-vc ffmpeg12,mpeg12,

Try libavcodec's MPEG-1/2 codec, then libmpeg2, then others.

-vfm <driver1,driver2,...>: Specify a priority list of video codec families to be used, according to their names in codecs.conf. Falls back on the default codecs if none of the given codec families work.
NOTE: See -vfm help for a full list of available codec families.
EXAMPLE:; -vfm ffmpeg,dshow,vfw

Try the libavcodec, then Directshow, then VfW codecs and fall back on others, if they do not work.

-vfm xanim

Try XAnim codecs first.

-x <x> (also see -zoom) (MPlayer only): Scale image to width <x> (if software/hardware scaling is available). Disables aspect calculations.
-xvidopts <option1:option2:...>: Specify additional parameters when decoding with XviD.
NOTE: Since libavcodec is faster than XviD you might want to use the libavcodec postprocessing filter (-vf pp) and decoder (-vfm ffmpeg) instead.
XviD's internal postprocessing filters:; deblock-chroma

chroma deblock filter

deblock-luma

luma deblock filter

dering-luma

luma deringing filter

dering-chroma

chroma deringing filter

filmeffect

Adds artificial film grain to the video. May increase perceived quality, while lowering true quality.

rendering methods:

dr2

Activate direct rendering method 2.

nodr2

Deactivate direct rendering method 2.

-xy <value> (also see -zoom): value<=8

Scale image by factor <value>.

value>8

Set width to value and calculate height to keep correct aspect ratio.

-y <y> (also see -zoom) (MPlayer only): Scale image to height <y> (if software/hardware scaling is available). Disables aspect calculations.
-zoom: Allow software scaling, where available. This will allow scaling with output drivers (like x11, fbdev) that do not support hardware scaling where MPlayer disables scaling by default for performance reasons.

Audio Filters

Audio filters allow you to modify the audio stream and its properties. The syntax is:

-af <filter1[=parameter1:parameter2:...],filter2,...>: Setup a chain of audio filters.
NOTE: To get a full list of available audio filters, see -af help. Available filters are:
resample[=srate[:sloppy[:type]]]: Changes the sample rate of the audio stream. Can be used if you have a fixed frequency sound card or if you are stuck with an old sound card that is only capable of max 44.1kHz. This filter is automatically enabled if necessary. It only supports 16-bit integer and float in native-endian format as input.
NOTE: With MEncoder, you need to also use -srate <srate>.; <srate>

output sample frequency in Hz. The valid range for this parameter is 8000 to 192000. If the input and output sample frequency are the same or if this parameter is omitted the filter is automatically unloaded. A high sample frequency normally improves the audio quality, especially when used in combination with other filters.

Allow (1) or disallow (0) the output frequency to differ slightly from the frequency given by <srate> (default: 1). Can be used if the startup of the playback is extremely slow.

<type>

Selects which resampling method to use.

0: linear interpolation (fast, poor quality especially when upsampling)
1: polyphase filterbank and integer processing
2: polyphase filterbank and floating point processing (slow, best quality)

EXAMPLE:

mplayer -af resample=44100:0:0

would set the output frequency of the resample filter to 44100Hz using exact output frequency scaling and linear interpolation.

lavcresample[=srate[:length[:linear[:count[:cutoff]]]]]: Changes the sample rate of the audio stream to an integer <srate> in Hz. It only supports the 16-bit native-endian format.
NOTE: With MEncoder, you need to also use -srate <srate>.; <srate>

the output sample rate

length of the filter with respect to the lower sampling rate (default: 16)

if 1 then filters will be linearly interpolated between polyphase entries

<count>

log2 of the number of polyphase entries (..., 10->1024, 11->2048, 12->4096, ...) (default: 10->1024)

cutoff frequency (0.0-1.0), default set depending upon filter length

sweep[=speed]: Produces a sine sweep.; <0.0-1.0>

Sine function delta, use very low values to hear the sweep.

sinesuppress[=freq:decay]: Remove a sine at the specified frequency. Useful to get rid of the 50/60Hz noise on low quality audio equipment. It probably only works on mono input.; <freq>

The frequency of the sine which should be removed (in Hz) (default: 50)

<decay>

Controls the adaptivity (a larger value will make the filter adapt to amplitude and phase changes quicker, a smaller value will make the adaptation slower) (default: 0.0001). Reasonable values are around 0.001.

hrtf[=flag]: Head-related transfer function: Converts multichannel audio to 2 channel output for headphones, preserving the spatiality of the sound.; Flag Meaning; m matrix decoding of the rear channel; s 2-channel matrix decoding; 0 no matrix decoding (default)
equalizer=[g1:g2:g3:...:g10]: 10 octave band graphic equalizer, implemented using 10 IIR band pass filters. This means that it works regardless of what type of audio is being played back. The center frequencies for the 10 bands are:; No. frequency; 0 31.25 Hz; 1 62.50 Hz; 2 125.00 Hz; 3 250.00 Hz; 4 500.00 Hz; 5 1.00 kHz; 6 2.00 kHz; 7 4.00 kHz; 8 8.00 kHz; 9 16.00 kHz; If the sample rate of the sound being played is lower than the center frequency for a frequency band, then that band will be disabled. A known bug with this filter is that the characteristics for the uppermost band are not completely symmetric if the sample rate is close to the center frequency of that band. This problem can be worked around by upsampling the sound using the resample filter before it reaches this filter.; <g1>:<g2>:<g3>:...:<g10>

floating point numbers representing the gain in dB for each frequency band (-12-12)

EXAMPLE:

mplayer -af equalizer=11:11:10:5:0:-12:0:5:12:12 media.avi

Would amplify the sound in the upper and lower frequency region while canceling it almost completely around 1kHz.

channels=nch[:nr:from1:to1:from2:to2:from3:to3:...]: Can be used for adding, removing, routing and copying audio channels. If only <nch> is given the default routing is used, it works as follows: 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.; <nch>

number of output channels (1-6)

<nr>

number of routes (1-6)

<from1:to1:from2:to2:from3:to3:...>

Pairs of numbers between 0 and 5 that define where to route each channel.

EXAMPLE:

mplayer -af channels=4:4:0:1:1:0:2:2:3:3 media.avi

Would change the number of channels to 4 and set up 4 routes that swap channel 0 and channel 1 and leave channel 2 and 3 intact. Observe that if media containing two channels was played back, channels 2 and 3 would contain silence but 0 and 1 would still be swapped.

mplayer -af channels=6:4:0:0:0:1:0:2:0:3 media.avi

Would change the number of channels to 6 and set up 4 routes that copy channel 0 to channels 0 to 3. Channel 4 and 5 will contain silence.

format[=format] (also see -format): Convert between different sample formats. Automatically enabled when needed by the sound card or another filter.; <format>

Sets the desired format. The general form is 'sbe', where 's' denotes the sign (either 's' for signed or 'u' for unsigned), 'b' denotes the number of bits per sample (16, 24 or 32) and 'e' denotes the endianness ('le' means little-endian, 'be' big-endian and 'ne' the endianness of the computer MPlayer is running on). Valid values (amongst others) are: 's16le', 'u32be' and 'u24ne'. Exceptions to this rule that are also valid format specifiers: u8, s8, floatle, floatbe, floatne, mulaw, alaw, mpeg2, ac3 and imaadpcm.

volume[=v[:sc]]: Implements software volume control. Use this filter with caution since it can reduce the signal to noise ratio of the sound. In most cases it is best to set the level for the PCM sound to max, leave this filter out and control the output level to your speakers with the master volume control of the mixer. In case your sound card has a digital PCM mixer instead of an analog one,
