|
|
|
|
<P><B>MEncoder</B> (<B>MPlayer</B>'s Movie Encoder) is a simple movie encoder,
|
|
designed to encode MPlayer-playable movies
|
|
(<B>AVI/ASF/OGG/DVD/VCD/VOB/MPG/MOV/VIV/FLI/RM/NUV/NET</B>) to other MPlayer-playable
|
|
formats (see below). It can encode with various codecs, like <B>DivX4</B> (1 or
|
|
2 passes), libavcodec, <B>PCM</B>/<B>MP3</B>/<B>VBRMP3</B> audio. Also has
|
|
powerful plugin system for video manipulation.</P>

<UL>

<LI><B>OPTIONAL</B> - read <B>MPlayer</B>'s compilation instruction.</LI>
|

<LI><B>OPTIONAL (LINUX ONLY)</B> - 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. You need them if you want DivX4
|
|
(1/2 pass) encoding.</LI>
|
|
<LI><B>OPTIONAL</B> - <A HREF="codecs.html#2.2.1.9">download and install
|
|
<B>XViD</B></A>. Not very useful, libavcodec's <I>mpeg4</I> codec
|
|
can encode with much better speed AND quality than XViD or DivX4/5.</LI>
|
|
<LI><B>OPTIONAL</B> - for libavcodec support, install libavcodec as
|
|
described in the <A HREF="codecs.html#2.2.1.2">libavcodec section</A>.</LI>
|
|
<LI><B>OPTIONAL</B> - download and compile <B>libmp3lame</B> (from lame 3.89beta or lame CVS).<BR>
|
|
<B>WARNING: DO NOT COMPILE LAME < 3.90 WITH <U>GCC 2.96</U>! It won't
|
|
work properly!</B><BR>
|
|
This
|
|
is needed for CBR/VBR MP3 audio encoding ability. Note that a single
|
|
<CODE>lame</CODE> binary isn't sufficient. BTW: the less optimization
|
|
you use for lame, the better the quality will be. You can test
|
|
quality by running <CODE>make test</CODE> after lame's compiling process
|
|
is over. The resulting number should be less than <B>30</B>. Don't
|
|
panic if it's <B>400</B> or so, you shouldn't heard any audible
|
|
quality decrease. Oh, and if your compiler doesn't even run <CODE>make test</CODE> ...
|
|
Well, delete that <B>GCC 2.96</B> or upgrade lame to at least <B>3.90</B>.</LI>

|
|
|
|
<P><U><B>2-pass encoding:</B></U> the name comes from the fact that this method encodes the file <I>twice</I>.
|
|
The first encoding (dubbed <I>pass</I>) creates some temporary files (*.log) with a
|
|
size of few megabytes, do not delete them yet (you can delete the AVI). In the second pass, the
|
|
2-pass output file is created, using the bitrate data from the temporary files. The resulting
|
|
file will have much better image quality. If this is the first time you heard
|
|
about this, you should consult some guides available on the Net.</P>
|
|
|
|
<P>This example shows how to encode a DVD to a 2-pass DivX4 AVI. Just two
|
|
commands are needed:<BR>
|
|
<CODE> rm frameno.avi</CODE> - remove this file, which
|
|
can come from a previous 3-pass encoding (it interferes with current one)<BR>
|
|
<CODE> mencoder -dvd 2 -lavcopts vcodec=mpeg4:more_options

|
|
|
|
<P><U><B>3-pass encoding:</B></U> this is an extension of 2-pass encoding,
|
|
where the audio encoding takes place in a separate pass. This method enables
|
|
estimation of recommended video bitrate in order to fit on a CD. Also, the
|
|
audio is encoded only once, unlike in 2-pass mode. The schematics:</P>

<P><B><A NAME=2.4.3.2>2.4.3.2. Rescaling movies</A></B></P>
|
|
|
|
<P>Often the need to resize movie images' size emerges. Its reasons can be many,
|
|
examples are decreasing output file size, encoding SVCDs to DivX. Ripped DVDs
|
|
are mostly rescaled, for example a 4:3 DVD should be 640x480, especially
|
|
when you want it to fit to 1 CD, and have good quality at the same time.
|
|
SVCDs have 480x480 size, and their header contains the aspect ratio the
|
|
player should use (Ex.: 480x480 + 4:3 = 640x480). However when encoding to
|
|
AVI (DivX) files, you have be aware that AVI headers don't store this
|
|
value. Thus, the only solution is rescaling.</P>
|
|
|
|
<P>The scaling process is handled by the <I>'scale'</I> video filter:
|
|
<CODE>-vop scale=X:Y</CODE>. Its quality can be set with the
|
|
<CODE>-sws</CODE> option. If it's not specified, <B>MEncoder</B> will use 0:
|
|
fast bilinear.</P>

|
