.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.

.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
.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. Do not use the bps value in the AVI header, instead
calculate it.
.TP
.B \-aid <audio stream id>
If source media contains multiple audio streams (for example DVDs), encode
the specified one.
.TP
.B \-vid <video stream id>
If source media contains multiple video streams, encode the specified one.
.TP
.B \-pp <value>
Apply a postprocess filter to enhance image quality. (values TODO)
.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
.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 \-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 \-lameopts
If encoding to MP3 with libmp3lame, you can specify its parameters here, like:

  -lameopts br=192

Available options:

    help         get help
    br=XXX       specify bitrate in
                 kbit <0-1024>
                 (only for CBR)
    q=XXX        Quality
                 (0-highest, 9-fastest)
                 (for VBR)
    vbr=XXX      variable bitrate method
                   0=cbr
                   1=mt
                   2=rh(default)
                   3=abr
                   4=mtrh
    cbr          constant bitrate
    mode=XXX     0=stereo
                 1=joint-stereo
                 2=dualchannel
                 3=mono
                 (default: auto)
    padding=XXX  0=no

                 2=adjust
    ratio=XXX    compression ratio <1-100>

.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.
.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.
