.SH DESCRIPTION
.I mencoder
MEncoder (MPlayer's Movie Encoder) is a simple movie encoder, designed to
encode MPlayer-playable movies (AVI/DVD/VCD/VOB/MPG/MOV/VIV/NET) to other
MPlayer-playable formats (see below). Currently it's in beta stage, and encodes
only to DivX4 (1 or 2 passes) video, PCM/MP3/VBRMP3 audio. Also has stream
copying abilities. In the future, there will be cropping, resizing filters, and
other interesting stuff.
.LP
.SH "GENERAL OPTIONS"
.TP
.I NOTE
Every "flag" option has "noflag" pair, e.g. -flag opposite is -noflag
.TP
.I NOTE
CHECK THE HTML DOCUMENTATION TOO !
.TP
.I NOTE
As MEncoder uses the same 'libmpdemux' as MPlayer, their options are
_sometimes the same_ ! So although for example the -sid option isn't
mentioned here, you can use it in MEncoder too! (for encoding DVD with
subtitles)
.TP
.B \-vcd <track number>
Encode the specified VCD track.
.TP
.B \-dvd <title number>
Encode the specified DVD title.
.TP
.B \-chapter <chapter id>
Use with -dvd option (see above). Start encoding at the specified chapter.
.TP
.B \-dvdangle <angle id>
Use with -dvd option (see above), and if the DVD disc has multiple angles.
It will encode the angle specified here.
.TP
.B \-dvdkey <key>
Used to decrypt CSS-encrypted streams on hard disk (with given CSS decrypt
key).
.TP
.B \-nobps
Used only for AVIs. Doesn't use the bps value in the AVI header, instead
calculates it.
.TP
.B \-aid <audio stream id>
If the source media contains multiple audio streams (for example DVDs), encode
the specified one.
.TP
.B \-vid <video stream id>
If the source media contains multiple video streams, encode the specified one.
.TP
.B \-pp <value>
See man mplayer.
.TP
.B \-vc <codec name>
Use specified codec (according to codecs.conf) for decoding input video
stream.
.TP
.B \-ac <codec name>
Use specified codec (according to codecs.conf) for decoding input audio
stream.
.TP
.B \-vfm <video codec family>
Force decoding by using a specific codec FAMILY, and FALLBACK to default
if failed. For examples see MPlayer manpage.
.TP
.B \-afm <audio codec family>
Force decoding by using a specific codec FAMILY, and FALLBACK to default
if failed. For examples see MPlayer manpage.
.TP
.B \-include
specify config file to be parsed after the default
.TP
.B \-mc\ seconds/5frame
maximum sync correction per 5 frames (in seconds).
Use -mc 0 to disable input A/V sync.
.TP
.B \-v
Increase verbosity.
.TP
.B \-ovc <codecname>
Encode with the given codec (codec names are from codecs.conf).
Examples:
-ovc help get help
-ovc copy no encoding, just streamcopy
-ovc divx4 encode to DivX4
-ovc lavc encode with a libavcodec codec
.TP
.B \-oac <codecname>
Encode with the given codec (codec names are from codecs.conf).
Examples:
-oac help get help
-oac copy no encoding, just streamcopy
-oac pcm encode to uncompressed PCM
-oac mp3lame encode to MP3 (using Lame)
.TP
.B \-nosound
Encode only video, no audio stream.
.TP
.B \-audiofile <file name>
Copy audio from external file.
.TP
.B \-mf <multifile options>
Used when encoding from multiple JPEG files.
Its sub-options are:
on turns on multifile support
w=<value> width of the output file
h=<value> height of the output file
fps=<value> fps of the output file
type=<value> type of input files (jpeg, png)
.TP
.B \-divx4opts
If encoding to DivX4, you can specify its parameters here, like:
-divx4opts br=1800:deinterlace:key=250
Available options:
help get help
br=XXX specify bitrate in
kbit <4-16000> or
bit <16001-24000000>
key=XXX maximum keyframe interval
(in frames)
deinterlace enable deinterlacing
(don't use, DivX4 is buggy!)
q=XXXX quality (1-fastest, 5-best)
min_quant=XXX minimum quantizer (0-32)
max_quant=XXX maximum quantizer (0-32)
rc_period=XXX rate control period
rc_reaction_period=XXX rate control
reaction period
rc_reaction_ratio=XXX rate control
reaction ratio
.TP
.B \-lavcopts
If encoding with a codec from libavcodec, you can specify its parameters here,
like:
-lavcopts vcodec=msmpeg4:vbitrate=1800:vhq:keyint=250
Available options:
help get help
vcodec=XXX use the specified codec :
mjpeg - Motion JPEG
h263 - H263
h263p - H263 Plus
mpeg4 - DivX 4/5
msmpeg4 - DivX 3
rv10 - an old RealVideo codec
mpeg1video - MPEG1 video :)
There's no default, you must
specify it.
vbitrate=XXX specify bitrate in
kbit <4-16000> or
bit <16001-24000000>
(warning: 1kbit = 1000 bits)
default = 800k
vratetol=XXX approximated *filesize* tolerance
in kbits.
(warning: 1kbit = 1000 bits)
default = 1024*8 kbits = 1MByte
keyint=XXX interval between keyframes
(specify in frames, >300 are not
recommended)
default = 250 (one key frame every
ten seconds in a 25fps movie)
vhq high quality mode, macro blocks
will be encoded multiple times and
the smallest will be used.
default = HQ disabled
vme=XXX [0..5] motion estimation method :
0 - no ME at all
1 - ME_FULL
2 - ME_LOG
3 - ME_PHODS
4 - ME_EPZS
5 - ME_X1
EPZS usually gives best results,
but you can try X1 too. FULL is
very slow and the others are
experimental.
default = EPZS
vqcomp=XXX if the value is set to 1.0, the
quantizer will stay nearly
constant (high motion scenes will
look bad). If it's 0.0, the
quantizer will be changed
to make all frames approximately
equally sized (low motion scenes
will look bad).
default = 0.5
vqblur=XXX blurs the quantizer graph over
time.
0.0 : no blur
1.0 : average all past
quantizers
default = 0.5
vqscale=XXX [2..31] gives each frame the same
quantizer (selects fixed quantizer
mode).
default = 0 (fixed quantizer mode
disabled)
vrc_strategy=X [0..2] different strategies to
decide which frames should get
which quantizer.
default = 2
v4mv 4 motion vectors per macroblock,
may gives you slightly better
quality, can only be used in HQ
mode and is buggy with B frames
currently.
default = disabled
vpass=X [1,2] select internal first pass
or second pass of 2-pass mode.
default = 0 (1-pass mode)
The next 3 options apply only to I & P frames :
vqmin=XX [1..31] minimum quantizer,
default = 3
vqmax=XX [1..31] maximum quantizer
default = 15
vqdiff=XX [1..31] quantizer difference.
Limits the maximum quantizer
difference between frames.
default = 3
The following options apply only to B frames :
vmax_b_frames=X [0..4] maximum number of frames
between each I/P frame.
default = 0 (B-frames generation
disabled)
vb_strategy=X strategy to choose between
I/P/B frames :
0 allways use max B
1 avoid B frames in high
motion / scene change (can
lead to filesize miss
prediction)
default = 0
In fixed quantizer mode you can use those options :
vqscale, vmax_b_frames, vhq, vme, keyint
You can use the following options only in pass 1 of 2-pass mode or in 1-pass mode :
vqblur, vqdiff
You can use the following options only in pass 2 of 2-pass mode :
vrc_strategy, vb_strategy
All other options can be used in all modes.
.TP
.B \-lameopts
If encoding to MP3 with libmp3lame, you can specify its parameters here, like:
-lameopts br=192:cbr
Available options:
help get help
vbr=XXX variable bitrate method
0=cbr
1=mt
2=rh(default)
3=abr
4=mtrh
abr average bitrate
cbr constant bitrate
br=XXX specify bitrate in
kbit <0-1024>
(only for CBR and ABR)
q=XXX Quality
(0-highest, 9-low)
(for VBR)
ratio=XXX compression ratio <1-100>
mode=XXX 0=stereo
1=joint-stereo
2=dualchannel
3=mono
(default: auto)
padding=XXX 0=no
1=all
2=adjust
.TP
.B \-pass <1/2>
With this you can encode 2pass DivX4 files. First encode with -pass 1, then
with the same parameters, encode with -pass 2.
NOTE: for libavcodec 2-pass use -lavcopts vpass=1/2 instead of -pass 1/2
.TP
.B \-passlogfile <filename>
When encoding in 2pass mode, MEncoder dumps first pass' informations
to the given file instead of the default divx2pass.log .
.TP
.B \-ofps <fps>
The output file will have different frame/sec than the source.
.TP
.B \-o <filename>
Outputs to the given filename, instead of the default 'test.avi' .
.TP
.B \-frames <number>
Encode only given number of frames.
.TP
.B \-ss <time>
seek to given time position. For example :
-ss 56 seeks to 56 seconds
-ss 01:10:00 seeks to 1 hour 10 min
Can start only from keyframes !
.TP
.B \-sub <subtitle file name>
given VOBsub/text subtitle will be encoded INTO the output file. Text
subtitles need fonts properly installed.
.TP
.B \-endpos <time>
stop encoding at given time. Can be specified in many was :
-endpos 56 encode only 56 seconds
-endpos 01:10:00 encode only 1 hours
Can be used in conjuction with -ss !
.TP
.B \-x <rescale width>
Rescale output movie to given pixels wide.
.TP
.B \-y <rescale height>
Rescale output movie to given pixels tall.
.TP
.B \-sws <0-2>
Type of scaling method
0 fast bilinear (default)
1 bilinear
2 bicubic (best quality)
.TP
.B \-ffourcc fourcc
Can be used to force the video fourcc of the output file. For example -ffourcc
div3 will have the output file contain "div3" as video fourcc.
