    Change a property by value, or increase by a default if value is
    not given or zero. The direction is reversed if direction is less
    than zero.

sub_alignment [value]
    Toggle/set subtitle alignment.
        0 top alignment
        1 center alignment
        2 bottom alignment

sub_delay <value> [abs]
    Adjust the subtitle delay by +/- <value> seconds or set it to <value>
    seconds when [abs] is nonzero.

sub_load <subtitle_file>
    Loads subtitles from <subtitle_file>.

sub_log
    Logs the current or last displayed subtitle together with filename
    and time information to ~/.mplayer/subtitle_log. Intended purpose
    is to allow convenient marking of bogus subtitles which need to be
    fixed while watching the movie.

sub_pos <value> [abs]
    Adjust/set subtitle position.

sub_remove [value]
    If the [value] argument is present and non-negative, removes the subtitle
    file with index [value]. If the argument is omitted or negative, removes
    all subtitle files.

sub_select [value]
    Display subtitle with index [value]. Turn subtitle display off if
    [value] is -1 or greater than the highest available subtitle index.
    Cycle through the available subtitles if [value] is omitted or less
    than -1. Supported subtitle sources are -sub options on the command
    line, VOBsubs, DVD subtitles, and Ogg and Matroska text streams.
    This command is mainly for cycling all subtitles, if you want to set
    a specific subtitle, use sub_file, sub_vob, or sub_demux.

sub_source [source]
    Display first subtitle from [source]. Here [source] is an integer:
    SUB_SOURCE_SUBS   (0) for file subs
    SUB_SOURCE_VOBSUB (1) for VOBsub files
    SUB_SOURCE_DEMUX  (2) for subtitle embedded in the media file or DVD subs.
    If [source] is -1, will turn off subtitle display. If [source] less than -1,
    will cycle between the first subtitle of each currently available sources.

sub_file [value]
    Display subtitle specifid by [value] for file subs. The [value] is
    corresponding to ID_FILE_SUB_ID values reported by '-identify'.
    If [value] is -1, will turn off subtitle display. If [value] less than -1,
    will cycle all file subs.

sub_vob [value]
    Display subtitle specifid by [value] for vobsubs. The [value] is
    corresponding to ID_VOBSUB_ID values reported by '-identify'.
    If [value] is -1, will turn off subtitle display. If [value] less than -1,
    will cycle all vobsubs.

sub_demux [value]
    Display subtitle specifid by [value] for subtitles from DVD or embedded
    in media file. The [value] is corresponding to ID_SUBTITLE_ID values
    reported by '-identify'. If [value] is -1, will turn off subtitle display.
    If [value] less than -1, will cycle all DVD subs or embedded subs.

sub_scale <value> [abs]
    Adjust the subtitle size by +/- <value> or set it to <value> when [abs]
    is nonzero.

vobsub_lang
    This is a stub linked to sub_select for backwards compatibility.

sub_step <value>
    Step forward in the subtitle list by <value> steps or backwards if <value>
    is negative.

sub_visibility [value]
    Toggle/set subtitle visibility.

forced_subs_only [value]
    Toggle/set forced subtitles only.

switch_audio [value] (currently MPEG*, AVI, Matroska and streams handled by libavformat)
    Switch to the audio track with the id [value]. Cycle through the
    available tracks if [value] is omitted or negative.

switch_ratio [value]
    Change aspect ratio at runtime. [value] is the new aspect ratio expressed
    as a float (e.g. 1.77778 for 16/9).
    There might be problems with some video filters.

switch_vsync [value]
    Toggle vsync (1 == on, 0 == off). If [value] is not provided,
    vsync status is inverted.

teletext_add_digit <value>
    Enter/leave teletext page number editing mode and append given digit to
    previously entered one.
    0..9 - Append apropriate digit. (Enables editing mode if called from normal
           mode, and switches to normal mode when third digit is entered.)
    -    - Delete last digit from page number. (Backspace emulation, works only
           in page number editing mode.)

teletext_go_link <1-6>
    Follow given link on current teletext page.

tv_start_scan
    Start automatic TV channel scanning.

tv_step_channel <channel>
    Select next/previous TV channel.

tv_step_norm
    Change TV norm.

tv_step_chanlist
    Change channel list.

tv_set_channel <channel>
    Set the current TV channel.

tv_last_channel
    Set the current TV channel to the last one.

tv_set_freq <frequency in MHz>
    Set the TV tuner frequency.

tv_step_freq <frequency offset in MHz>
    Set the TV tuner frequency relative to current value.

tv_set_norm <norm>
    Set the TV tuner norm (PAL, SECAM, NTSC, ...).

tv_set_brightness <-100 - 100> [abs]
    Set TV tuner brightness or adjust it if [abs] is set to 0.

tv_set_contrast <-100 -100> [abs]
    Set TV tuner contrast or adjust it if [abs] is set to 0.

tv_set_hue <-100 - 100> [abs]
    Set TV tuner hue or adjust it if [abs] is set to 0.

tv_set_saturation <-100 - 100> [abs]
    Set TV tuner saturation or adjust it if [abs] is set to 0.

use_master
    Switch volume control between master and PCM.

vo_border [value]
    Toggle/set borderless display.

vo_fullscreen [value]
    Toggle/set fullscreen mode.

vo_ontop [value]
    Toggle/set stay-on-top.

vo_rootwin [value]
    Toggle/set playback on the root window.

volume <value> [abs]
    Increase/decrease volume or set it to <value> if [abs] is nonzero.


The following commands are really only useful for OSD menu console mode:

help
    Displays help text, currently empty.

exit
    Exits from OSD menu console. Unlike 'quit', does not quit MPlayer.

hide
    Hides the OSD menu console. Clicking a menu command unhides it. Other
    keybindings act as usual.

run <value>
    Run <value> as shell command. In OSD menu console mode stdout and stdin
    are through the video output driver.
