<P><B><A NAME=2.4>2.4. Encoding with MEncoder</A></B></P>
<P><B><I>Overview</I></B>
<P><B>MEncoder</B> (<B>MPlayer</B>'s Movie Encoder) is a simple movie encoder,
designed to encode MPlayer-playable movies
(<B>AVI/DVD/VCD/VOB/MPG/MOV/VIV/NET</B>) to other MPlayer-playable formats (see
below). Currently it's in beta stage, and encodes only to <B>DivX4</B> (1 or 2
passes) video, <B>PCM</B>/<B>MP3</B>/<B>VBRMP3</B> audio. Also has stream
copying abilities. In the future, there will be cropping, resizing filters, and
other interesting stuff.</P>
<P><B><I>Compiling</I></B>
<UL>
<LI>read <B>MPlayer</B>'s compilation instructions, it contains info about
how to install <I>libdvdread</I> for <B>DVD</B> support, etc.</LI>
<LI>download the newest <B>DivX4linux</B> libs
from <A HREF="http://avifile.sourceforge.net/download.htm">avifile.sourceforge.net</A>,
and have them PROPERLY installed. This is needed for DivX4 (1/2 pass)
encoding.</LI>
<LI>download and install <B>libmp3lame</B> (from lame 3.89beta or lame CVS). This
is needed for CBR/VBR MP3 audio encoding ability. Note that a single
<CODE>lame</CODE> binary isn't sufficient.</LI>
<LI>use <CODE>./configure</CODE> with optional parameters as usual, and
type : <CODE>make mencoder</CODE> . You have to install it manually for
now.
</UL>
</P>
<P>You are ready. As you probably know, other encoding tools need the
<I>avifile</I> library installed. <B>MEncoder</B> doesn't need it at all.</P>
<P><B><I>MEncoder features</I></B> :
<UL>
<LI>encoding from the wide range of fileformats and decoders of <B>MPlayer</B>
<LI>encoding/multiplexing to interleaved AVI files with proper index</LI>
<LI>1 or 2 pass <B>DivX4</B> video</LI>
<LI><B>VBR</B> MP3 audio</LI>
<LI>PCM audio</LI>
<LI>stream copying (only from AVI/ASF now, and CBR audio only)</LI>
<LI>input A/V synchronizing (PTS-based, can be disabled with -mc 0 option)</LI>
<LI>FPS correction with <CODE>-ofps</CODE> option (useful when encoding
29.97fps VOB to 24fps AVI)</LI>
</UL>
</P>
<P><B><I>Planned features</I></B> :
<UL>
<LI>using audio from separate file (AC3, MP3, OGG)</LI>
<LI>VBR audio stream copy</LI>
<LI>even wider variety of available en/decoding formats/codecs
(creating VOB files with DivX4/Indeo5/VIVO streams :)</LI>
</UL>
</P>
<P><B><I>Examples</I></B></P>
<P>Using <B>MEncoder</B> is the easiest thing on Earth. See the following :</P>
<P>Encoding from DVD, title 2 :<BR>
<CODE> mencoder -dvd 2 -o title2.avi</CODE></P>
<P>Encoding from HTTP :<BR>
<CODE> mencoder http://mplayer.hq/example.avi -o example.avi</CODE></P>
<P>Encoding from standard input :<BR>
<CODE> rar p test-SVCD.rar | mencoder -divx4opts br=800 -ofps 24 -pass 1 -- -</CODE></P>
<P>For all available options, <B><I>check the MEncoder man page !</I></B>
