.
.SH DESCRIPTION
.B mplayer
is a movie player for LINUX (runs on many other Unices and non\-x86 CPUs, see
the documentation).
It plays most MPEG/\:VOB, AVI, ASF/\:WMA/\:WMV, RM, QT/\:MOV/\:MP4, OGG/\:OGM,
VIVO, FLI, NuppelVideo, yuv4mpeg, FILM and RoQ files, supported by many
native, XAnim, and Win32 DLL codecs.
You can watch VideoCD, SVCD, DVD, 3ivx, DivX\ 3/\:4/\:5 and even WMV movies,
too (without using the avifile library).
.PP
Another great feature of MPlayer is the wide range of supported output
drivers.
It works with X11, XV, DGA, OpenGL, SVGAlib, fbdev, AAlib, DirectFB, but you
can also use GGI, SDL (and this way all their drivers), VESA (on every VESA
compatible card, even without X11), some low level card-specific drivers (for
Matrox, 3Dfx and ATI) and some hardware MPEG decoder boards, such as the
Siemens DVB, DXR2 and DXR3/\:Hollywood+.
Most of them support software or hardware scaling, so you can enjoy movies in
fullscreen.
.PP
MPlayer has an onscreen display (OSD) for status information, nice big
antialiased shaded subtitles and visual feedback for keyboard controls.
European/\:ISO 8859-1,2 (Hungarian, English, Czech, etc), Cyrillic and Korean
fonts are supported along with 10 subtitle formats (MicroDVD, SubRip,
SubViewer, Sami, VPlayer, RT, SSA, AQTitle, JACOsub and our own: MPsub) and
DVD subtitles (SPU streams, VobSub and Closed Captions).
.PP
.B mencoder
(MPlayer's Movie Encoder) is a simple movie encoder, designed to encode
MPlayer-playable movies (see above) to other MPlayer-playable formats (see
below).
It encodes to DivX4, XviD, one of the libavcodec codecs and PCM/\:MP3/\:VBRMP3
audio in 1, 2 or 3\ passes.
Furthermore it has stream copying abilities, a powerful plugin system (crop,
expand, flip, postprocess, rotate, scale, noise, rgb/\:yuv conversion) and
more.
.PP
.B gmplayer
is MPlayer with a graphical user interface.
It has the same options as MPlayer.


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

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

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

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

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

.PD 0
.RSs
.IPs conf=<file>
Read alternative input.conf.
If given without pathname, ~/\:.mplayer is assumed.
.IPs ar\-delay
Delay in msec before we start to autorepeat a key (0 to disable).
.IPs ar\-rate
How many key presses per second when we autorepeat.
.IPs keylist
Prints all keys that can be bound.
.IPs cmdlist
Prints all commands that can be bound.
.IPs js\-dev
Specifies the joystick device to use (default is /dev/\:input/\:js0).
.IPs file
Read commands from the given file.
Mostly useful with a fifo.
.RE
.PD 1
.
.TP
.B \-lircconf <file>
Specifies a configuration file for LIRC (Linux Infrared Remote Control, see
http://www.lirc.org) if you don't like the default ~/\:.lircrc.
.TP
.B \-loop <number>
Loops movie playback <number> times.
0 means forever.
.TP
.B \-menu (BETA CODE)
Turn on OSD menu support.
.TP
.B \-menu-root <value> (BETA CODE)
Specify the main menu.
.TP
.B \-menu-cfg <file> (BETA CODE)
Use an alternative menu.conf.
.TP
.B \-nojoystick
Turns off joystick support.
Default is on, if compiled in.
.TP
.B \-nolirc
Turns off LIRC support.
.TP
.B \-nortc \ \ 
Turns off usage of the Linux RTC (real-time clock \- /dev/\:rtc) as timing
mechanism.
.TP
.B \-playlist <file>
Play files according to a playlist (1 file per row or Winamp or ASX format).
.TP
.B \-quiet \ \ 
Display less output and status messages.
.TP
.B \-really\-quiet \ \ 
Display even less output and status messages.
.TP
.B \-sdp
Specifies that the input file is a SDP ('Session Description Protocol')
file that describes an RTP session (see http://www.live.com/mplayer/).
.TP
.B \-shuffle \ \ 
Play files in random order.
.TP
.B \-skin <skin\ directory> (BETA CODE)
Load skin from the given directory (WITHOUT path name).

.I EXAMPLE:
.PD 0
.RSs
.IPs "\-skin fittyfene"
tries Skin/fittyfene.
It first checks
/usr/local/share/mplayer/
and afterwards ~/.mplayer/.
.RE
.PD 1
.
.TP
.B \-slave \ \ 
This option switches on slave mode.
This is intended for use of MPlayer as a backend to other programs.
Instead of intercepting keyboard events, MPlayer will read simplistic command
lines from its stdin.
The section
.B SLAVE MODE PROTOCOL
explains the syntax.
.TP
.B \-softsleep
Uses high quality software timers.
As precise as the RTC without requiring special privileges.
Comes at the price of higher CPU consumption.
.TP
.B \-speed <0.01\-100>
Set playback speed rate.
.TP
.B \-sstep <sec>
Specifies seconds between displayed frames.
Useful for slideshows.


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

.I EXAMPLE:
.PD 0
.RSs
.IPs "\-alang hu,en"
Plays Hungarian and falls back to English if Hungarian is not available.
.RE
.PD 1
.
.TP
.B \-audio\-demuxer <number> (\-audiofile only)
Force audio demuxer type for \-audiofile.
Give the demuxer ID as defined in demuxers.h.
Use \-audio\-demuxer 17 to force .mp3 detection.
.TP
.B \-audiofile <filename>
Play audio from an external file (WAV, MP3 or Ogg Vorbis) while viewing a
movie.
.TP
.B -audiofile-cache <kBytes>
Enables caching for the stream used by -audiofile, using the specified
amount of memory.
.TP
.B \-bandwidth <value>
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.
.TP
.B \-cdrom\-device <path\ to\ device>
Override default CDROM drive name /dev/\:cdrom.
.TP
.B \-cache <kBytes>
This option specifies how much memory (in kBytes) to use when precaching a
file/\:URL.
Especially useful on slow media (default is \-nocache).
.TP
.B \-cdda <option1:option2>
This option can be used to tune the CD Audio reading feature of MPlayer.
.br
Available options are:
.
.RSs
.IPs speed=<value>
set CD spin speed
.IPs paranoia=<0\-2>
set paranoia level
.RSss
0: disable checking
.br
1: overlap checking only (default)
.br
2: full data correction and verification
.REss
.IPs generic-dev=<value>
use specified generic SCSI device
.IPs sector-size=<value>
atomic read size
.IPs overlap=<value>
force minimum overlap search during verification to <value> sectors.
.IPs 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.
.IPs toc-offset=<value>
Add <value> sectors to the values reported when addressing tracks.
May be negative.
.IPs (no)skip
(never) accept imperfect data reconstruction.
.RE
.
.TP
.B \-channels <number>
Change the number of playback channels, defaults to '2' if not specified.
If the number of output channels is bigger than the number of input channels
empty channels are inserted (unless mixing from mono to stereo, then the mono
channel is repeated in both output channels).
If the number of output channels is smaller than the number of input channels,
results depend on the audio decoder (\-afm).
MPlayer asks the decoder to decode the audio into as many channels as
specified.
Now it's up to the decoder to fulfill the requirement.
If the decoder outputs more channels than requested, the exceeding channels
are truncated.
This is usually only important when playing videos with AC3 audio (like DVDs).
In that case liba52 does the decoding by default and correctly downmixes the
audio into the requested number of channels.

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

.PD 0
.RSs
.IPs 2
Stereo
.IPs 4
Surround
.IPs 6
Full 5.1
.RE

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

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

.PD 1
.
.TP
.B \-ni (.AVI only)
Force usage of non\-interleaved AVI parser (fixes playing
of some bad AVI files).
.TP
.B \-nobps (.AVI only)
Do not use average byte/\:sec value for A\-V sync (AVI).
Helps with some AVI files with broken header.
.TP
.B \-noextbased
Disables filename-extension based demuxer selection.
By default, when file type (demuxer) cannot be detected reliably
(the file has no header or it is not reliable enough), the filename
extension is used to select demuxer. It always falls back to content-based
demuxer selection.
.TP
.B \-passwd <password> (see \-user option too)
Specify password for http authentication.
.TP
.B \-rawaudio <option1:option2:...>
This option lets you play raw audio files.

.B \-rtsp-stream-over-tcp
Used with 'rtsp://' URLs to specify that the resulting incoming RTP and RTCP
packets be streamed over TCP (using the same TCP connection as RTSP).
This option may be useful if you have a broken Internet connection that does
not pass incoming UDP packets (see http://www.live.com/mplayer/).
.TP
.B \-skipopening
Skip DVD opening (dvdnav only).
.TP
.B \-sb <byte\ position> (see \-ss option too)
Seek to byte position.
Useful for playback from CDROM images / .VOB files with junk at the beginning.
.TP

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

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

.IPs chanlist=<value>
available: europe-east, europe-west, us-bcast, us-cable, etc
.IPs channels=<channel>\-<name>,<channel>\-<name>,...
Set names for channels.
Use _ for spaces in names (or play with quoting ;-).
The channel names will then be written using OSD, and the commands tv_step_channel,
tv_set_channel and tv_last_channel will then be usable using a remote (see lirc).
Not compatible with frequency parameter.
Warning: The channel number will then be the position in the 'channels' list,
beginning with 1.
Example: use tv://1, tv://2, tv_set_channel 1, tv_set_channel 2, etc.
.IPs [brightness|contrast|hue|saturation]=<\-100\-100>
set the color equalizer on the video card.
.IPs audiorate=<value>
set audio capture bitrate
.IPs forceaudio
capture audio even if there are no audio sources reported by v4l
.IPs alsa
capture from ALSA
.IPs amode=<0\-3>
choose an audio mode:
.RSss
0: mono
.br
1: stereo
.br
2: language 1
.br
3: language 2
.REss
.IPs forcechan=<1\-2>
By default, the count of recorded audio channels is determined automatically
by querying the audio mode from the tv card.
This option allows to force stereo/\:mono recording regardless of the amode
option and the values returned by v4l.
This can be used for troubleshooting when the tv card is unable to report the
current audio mode.
.IPs adevice=<value>
set an audio device
.RSss
/dev/\:...\& for OSS
.br
hardware ID for ALSA
.REss
.IPs audioid=<value>
choose an audio output of the capture card, if it has more of them
.IPs "[volume|bass|treble|balance]=<0\-65535>"
These options set parameters of the mixer on the video capture card.
They will have no effect, if your card doesn't have one.
.IPs immediatemode=<bool>
A value of 0 means capture and buffer audio and video together
(default for mencoder).
A value of 1 (default for mplayer) means to do video capture only and let the
audio go through a loopback cable from the TV card to the soundcard.
.IPs 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).
.IPs decimation=<1,2,4>
choose the size of the picture that will be compressed by hardware
mjpeg compression:

This option is used to control the dxr2 driver.
Note: The lavc filter is now auto inserted if you try to play a non MPEG1/2
format so all formats supported by MPlayer should play out of the box (if
you have the CPU power needed to encode on the fly).
The overlay chipset used on the dxr2 is of pretty bad quality but the default
settings should work for everybody.
The OSD may be usable with the overlay (not on TV) by drawing it in the
colorkey.
With the default colorkey settings you may get variable results, usually you
will see the colorkey around the characters or some other funny effect.
But if you properly adjust the colorkey settings you should be able to get
acceptable results.

.IPs rotate[=<0-7>]
Rotates and flips (optional) the image +/\:\- 90 degrees.
For parameters between 4-7 rotation is only done if the movie's geometry is
portrait and not landscape.
.IPs scale[=w:h[:c[:p]]]
Scales the image with the software scaler (slow) and performs a YUV<\->RGB
colorspace conversion (also see \-sws option).
.RSss
w,h: new width/height after scaling (default: original width,height)
    Note: If -zoom is used, and underlying filters (including libvo) are
    incapable of scaling, then it defaults to d_width/\:d_height!
    -1: original width/\:height
    0:  scaled d_width/\:d_height
    -2: Calculate w/\:h using the other dimension and the prescaled aspect ratio.
    -3: Calculate w/\:h using the other dimension and the original aspect ratio.
.br
c:   chroma skipping
    0: use all available input lines for chroma
    1: use only every 2. input line for chroma
    2: use only every 4. input line for chroma
    3: use only every 8. input line for chroma
.br
p:  scaling parameter (depends upon the scaling method used)
    for -sws 2 (bicubic)  it is sharpness (0 (soft) - 100 (sharp))
    for -sws 7 (gaussian) it is sharpness (0 (soft) - 100 (sharp))

.IPs eq[=bright:cont]
Software equalizer with interactive controls just like the hardware
equalizer, for cards/\:drivers that do not support brightness and
contrast controls in hardware.
Might also be useful with MEncoder, either for fixing poorly captured
movies, or for slightly reducing contrast to mask artifacts and get by
with lower bitrates.
Initial values in the range -100 \- 100 may be given on the command line.
.IPs eq2[=gamma:contrast:brightness:saturation:rg:gg:bg]
Alternative software equalizer that uses lookup tables (very slow),
allowing gamma correction in addition to simple brightness,
contrast and saturation adjustment. Note that it uses the same MMX
optimized code as \-vf eq if all gamma values are 1.0.
The parameters are given as floating point values.
Parameters rg, gg, bg are the independent gamma values for the Red, Green
and Blue components.
Defaults are 1.0, brightness=0.0.
Value ranges are 0.1\-10 for gammas, -2\-2 for contrast (negative values result
in a negative image), -1\-1 for brightness and 0\-3 for saturation.
.IPs halfpack[=f]
Convert planar YUV 4:2:0 to half-height packed 4:2:2, downsampling luma but
keeping all chroma samples.
Useful for output to low-resolution display devices when hardware downscaling
is poor quality or is not available.
Can also be used as a primitive luma-only deinterlacer with very low cpu
usage.
By default, halfpack averages pairs of lines when downsampling.
The optional parameter f can be 0 to only use even lines, or 1 to only use
odd lines.
Any other value for f gives the default (averaging) behavior.
.IPs dint[=sense:level]
Detects and drops first of interlaced frames in video stream.
Values can be from 0.0 to 1.0 - first (default 0.1) is relative difference
between neighbor pixels, second (default 0.15) is what part of image have to
be detected as interlaced to drop the frame.
.IPs lavcdeint

.REss
.IPs swapuv

.IPs "il=[d|i][s][:[d|i][s]]"
(de)interleaves lines.
The goal of this filter is to add the ability to process interlaced images
pre-field without deinterlacing them.
You can filter your interlaced DVD and play it on a TV without breaking the
interlacing.
While deinterlacing (with the postprocessing filter) removes interlacing
permanently (by smoothing, averaging, etc) deinterleaving splits the frame into
2 fields (so called half pictures), so you can process (filter) them
independently and then re-interleave them.
.RSss
d: deinterleave
.br
i: interleave
.br
s: swap fields (exchange even & odd lines)
.REss
.IPs "field[=n]"
Extracts a single field from an interlaced image using stride arithmetic
to avoid wasting CPU time. The optional argument n specifies whether
to extract the even or the odd field (depending on whether n is even
or odd).
.IPs "detc[=var1=value2:var2=value2:...]"
Attempts to reverse the "telecine" process to recover a clean,
non-interlaced stream at film framerate. This filter is still
experimental but seems to be usable. The following arguments (see
syntax above) may be used to control its behavior:
.RSss
dr: Set the frame dropping mode. 0 (default) means don't drop frames
to maintain fixed output framerate. 1 means always drop a frame when
there have been no drops or telecine merges in the past 5 frames. 2
means always maintain exact 5:4 input to output frame ratio. (Note:
use mode 1 with MEncoder!)
.br
am: Analysis mode. Available values are 0 (fixed pattern with initial
frame number specified by fr=#) and 1 (agressive search for telecine
pattern). Default is 1.
.br
fr: Set initial frame number in sequence. 0-2 are the three clean
progressive frames; 3 and 4 are the two interlaced frames. The
default, -1, means "not in telecine sequence". The number specified
here is the type for the imaginary previous frame before the movie
starts.
.br
tr0, tr1, tr2, tr3: Threshold values to be used in certain modes.
.REss
.IPs "telecine[=start]"
Apply 3:2 "telecine" process to increase framerate by 20%. This most
likely will not work correctly with mplayer, but it can be used
with 'mencoder -fps 29.97 -ofps 29.97 -vf telecine'. Both fps options are
essential! (A/V sync will break if they are wrong.) The optional start
parameter tells the filter where in the telecine pattern to start
(0-3).
.IPs "tfields[=mode]"
Temporal field separation -- split fields into frames, doubling the
output framerate. In mode 0, the filter will leave the fields
unchanged, resulting in half-height output. In mode 1, interlaced
parts of the image will be interpolated to reconstruct full-height
frames. Like the telecine filter, "tfields" will only work properly
with mencoder, and only if both -fps and -ofps are set to the desired
(double) framerate!

Available options are:
.
.RSs
.IPs pass=<1|2>
specify the pass in 2pass mode
.IPs bitrate=<value>
sets the bitrate to be used in kbits/\:second if <16000 or in bits/\:second
if >16000
(CBR or 2pass mode, default=687 kbits/s)
.IPs fixed_quant=<1\-31>
switch to fixed quantizer mode and specify the quantizer to be used
.IPs me_quality=<0\-6>
specify the motion detection quality (default=4)
.IPs 4mv
use 4 motion vectors per macro-block, might give better compression at the
cost of a slower encoding (default=off)
.IPs rc_reaction_delay_factor=<value>
specify how fast the rate control reacts, lower values are faster
.IPs rc_averaging_period=<value>
period to reach the required average
.IPs rc_buffer=<value>
size of the rate control buffer
.IPs quant_range=<1\-31>\-<1\-31>[/<1\-31>\-<1\-31>]

min & max quantizer for I/P frames (default=2\-31/2\-31, 2pass mode)
.IPs min_key_interval=<value>
minimum interval between key frames (default=0, 2pass only)
.IPs max_key_interval=<value>
maximum interval between key frames (default=10*fps)
.IPs mpeg_quant
use MPEG quantizers instead of H.263 (default=off)
.IPs mod_quant
decide whether to use MPEG or H.263 quantizers on a frame-by-frame basis.
(default=off, 2pass mode only)
.IPs lumi_mask
use a lumimasking algorithm (default=off, seems buggy)
.IPs hintedme
save Motion Estimation vectors to a file during the first pass and reuse this
file during the second (default=off, 2pass mode only, seems buggy)
.IPs hintfile
specify the temporary file to be used by the 'hintedme' option
