.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

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)

When encoding in 2pass mode, MEncoder dumps first pass' informations
to the given file instead of the default divx2pass.log .
.TP

The output file will have different frame/sec than the source.
.TP

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 \-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.
