.\" Usage
.\" --------------------------------------------------------------------------
.
.SH "USAGE"
Every 'flag' option has a 'noflag' counterpart, e.g.\& the opposite of the
\-fs option is \-nofs.
.PP
If an option is marked as (XXX only), it will only work in combination with
the XXX option or if XXX is compiled in.
.PP
.I NOTE:
The suboption parser (used for example for \-ao pcm suboptions) supports
a special kind of string-escaping intended for use with external GUIs.
.br
It has the following format:
.br
%n%string_of_length_n
.br
.I EXAMPLES:
.br
mplayer \-ao pcm:file=%10%C:test.wav test.avi
.br
Or in a script:
.br
mplayer \-ao pcm:file=%`expr length "$NAME"`%"$NAME" test.avi

.\" Configuration files
.\" --------------------------------------------------------------------------
.
.SH "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.
.PP
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).

.SH "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.

.SH "GENERAL OPTIONS"
.
.TP
.B \-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.
.
.TP
.B \-include <configuration file>
Specify configuration file to be parsed after the default ones.
.
.TP
.B \-list\-options
Prints all available options.
.
.TP
.B \-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).
.br
.I 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.
.
.TP
.B \-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.
.br
.I NOTE:
Some messages are printed before the command line is parsed and are
therefore not affected by \-msglevel.
To control these messages you have to use the MPLAYER_VERBOSE environment
variable, see its description below for details.
.br

.TP
.B "\-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).
.
.TP
.B \-priority <prio> (Windows only)
Set process priority for MPlayer according to the predefined
priorities available under Windows.
Possible values of <prio>:
.RSs
idle|belownormal|normal|abovenormal|high|realtime
.RE
.sp 1
.RS
.I WARNING:
Using realtime priority can cause system lockup.
.RE
.
.TP
.B \-profile <profile1,profile2,...>
Use the given profile(s), \-profile help displays a list of the defined profiles.
.
.TP
.B \-really\-quiet (also see \-quiet)
Display even less output and status messages than with \-quiet.
Also suppresses the GUI error message boxes.
.
.TP
.B \-show\-profile <profile>
Show the description and content of a profile.
.
.TP
.B \-use\-filedir\-conf
Look for a file-specific configuration file in the same directory as
the file that is being played.
.br
.I WARNING:
May be dangerous if playing from untrusted media.
.
.TP
.B "\-v\ \ \ \ \ "
Increment verbosity level, one level for each \-v
found on the command line.
.
.
.
.SH "PLAYER OPTIONS (MPLAYER ONLY)"
.
.TP
.B \-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.
.
.TP
.B \-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.
.
.TP
.B \-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.
.br
.I NOTE:
With this option MPlayer will also ignore frame duration when playing
only video (you can think of that as infinite fps).
.
.TP
.B \-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.
.
.TP
.B \-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.
.
.TP
.B \-correct\-pts (experimental)
Switches MPlayer to an experimental mode where timestamps for video frames
are calculated differently and video filters which add new frames or
modify timestamps of existing ones are supported.
The more accurate timestamps can be visible for example when playing
subtitles timed to scene changes with the \-ass option.
Without \-correct\-pts the subtitle timing will typically be off by some frames.
This option does not work correctly with some demuxers and codecs.
.
.TP
.B \-crash\-debug (DEBUG CODE)
Automatically attaches gdb upon crash or SIGTRAP.
Support must be compiled in by configuring with \-\-enable\-crash\-debug.
.
.TP
.B \-doubleclick\-time
Time in milliseconds to recognize two consecutive button presses as
a double-click (default: 300).
Set to 0 to let your windowing system decide what a double-click is
(\-vo directx only).
.br
.I NOTE:
You will get slightly different behaviour depending on whether you bind
MOUSE_BTN0_DBL or MOUSE_BTN0\-MOUSE_BTN0_DBL.
.
.TP
.B \-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.
.
.TP
.B \-enqueue (GUI only)
Enqueue files given on the command line in the playlist instead of playing them
immediately.
.
.TP
.B \-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.
.
.TP
.B \-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.
.
.TP
.B \-(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.
.
.TP
.B \-h, \-help, \-\-help
Show short summary of options.
.
.TP
.B \-hardframedrop
More intense frame dropping (breaks decoding).
Leads to image distortion!
.
.TP
.B \-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 chapters and 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.
.
.TP
.B \-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.
.
.TP
.B \-input <commands>
This option can be used to configure certain parts of the input system.
Paths are relative to ~/.mplayer/.
.br
.I NOTE:
Autorepeat is currently only supported by joysticks.
.sp 1
Available commands are:
.sp 1
.PD 0
.RSs
.IPs conf=<filename>
Specify input configuration file other than the default
~/\:.mplayer/\:input.conf.
~/\:.mplayer/\:<filename> is assumed if no full path is given.
.IPs ar-delay
Delay in milliseconds before we start to autorepeat a key (0 to disable).
.IPs ar-rate
Number of key presses to generate per second on autorepeat.
.IPs keylist
Prints all keys that can be bound to commands.
.IPs cmdlist
Prints all commands that can be bound to keys.
.IPs js-dev
Specifies the joystick device to use (default: /dev/\:input/\:js0).
.IPs file=<filename>
Read commands from the given file.
Mostly useful with a FIFO.
.br
.I 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.
.RE
.PD 1
.
.TP
.B \-key\-fifo\-size <2\-65000>
Specify the size of the FIFO that buffers key events (default: 7).
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.
.
.TP
.B \-lircconf <filename> (LIRC only)
Specifies a configuration file for LIRC (default: ~/.lircrc).
.
.TP
.B \-list\-properties
Print a list of the available properties.
.
.TP
.B \-loop <number>
Loops movie playback <number> times.
0 means forever.
.
.TP
.B \-menu (OSD menu only)
Turn on OSD menu support.
.
.TP
.B \-menu\-cfg <filename> (OSD menu only)
Use an alternative menu.conf.
