<para>

This section contains information about the DivX4 and DivX5 codecs of
|
|
<ulink url="http://www.projectmayo.com">Project Mayo</ulink>.
|
|
Their first available alpha version was OpenDivX 4.0 alpha 47 and 48.
|
|
Support for this was included in <application>MPlayer</application> in the
|
|
past, and built by default. We also used its postprocessing code to
|
|
optionally enhance visual quality of MPEG1/2 movies. Now we use our own,
|
|
for all file types.
|
|
</para>
|
|
|
|
<para>
|
|
The new generation of this codec is called DivX4 and can even decode
|
|
movies made with the infamous DivX codec! In addition it is much faster
|
|
than the native Win32 DivX DLLs but slower than <systemitem
|
|
class="library">libavcodec</systemitem>. Hence its usage as a decoder is
|
|
<emphasis role="bold">DISCOURAGED</emphasis>. However, it is useful for
|
|
encoding. One disadvantage of this codec is that it is not available under an
|
|
Open Source license.
|
|
</para>
|
|
|
|
<para>
|
|
DivX4 works in two modes:
|
|
<variablelist>
|
|
<varlistentry><term><option>-vc odivx</option></term>
|
|
<listitem><simpara>
|
|
Uses the codec in OpenDivX fashion. In this case it produces YV12 images
|
|
in its own buffer, and <application>MPlayer</application> does colorspace
|
|
conversion via libvo. (<emphasis role="bold">Fast, recommended!</emphasis>)
|
|
</simpara></listitem>
|
|
</varlistentry>
|
|
<varlistentry><term><option>-vc divx4</option></term>
|
|
<listitem><simpara>
|
|
Uses the colorspace conversion of the codec. In this mode you can use
|
|
YUY2/UYVY, too. (<emphasis role="bold">SLOW</emphasis>)
|
|
</simpara></listitem>
|
|
</varlistentry>
|
|
</variablelist>
|
|
</para>
|
|
|
|
<para>
|
|
The <option>-vc odivx</option> method is usually faster, due to the fact
|
|
that it transfers image data in YV12 (planar YUV 4:2:0) format, thus
|
|
requiring much less bandwidth on the bus. For packed YUV modes (YUY2, UYVY)
|
|
use the <option>-vc divx4</option> method. For RGB modes the speed is the
|
|
same, differing at best according to your current color depth.
|
|
<note>
|
|
<para>
|
|
If your <option>-vo</option> driver supports direct rendering, then <option>-vc
|
|
divx4</option> may be faster, or even the fastest solution.

This is the default decoder used for files with AC3 audio.
|

</para>
|
|
|
|
<para>
|
|
The AC3 decoder can create audio output mixes for 2, 4, or 6 speakers.
|
|
When configured for 6 speakers, this decoder provides separate output of
|
|
all the AC3 channels to the sound driver, allowing for full "surround
|
|
sound" experience without the external AC3 decoder required to use the
|
|
hwac3 codec.
|
|
</para>
|
|
|
|
<para>
|
|
Use the <option>-channels</option> option to select the number of output
|
|
channels. Use <option>-channels 2</option> for a stereo downmix. For a 4
|
|
channel downmix (Left Front, Right Front, Left Surround and Right Surround
|
|
outputs), use <option>-channels 4</option>. In this case, any center
|
|
channel will be mixed equally to the front channels. <option>-channels
|
|
6</option> will output all the AC3 channels as they are encoded - in the
|
|
order Left, Right, Left Surround, Right Surround, Center and LFE.
|
|
</para>
|
|
|
|
<para>
|
|
The default number of output channels is 2.
|
|
</para>
|
|
|
|
<para>
|
|
To use more than 2 output channels, you will need to use OSS, and have a
|
|
sound card that supports the appropriate number of output channels via the
|
|
SNDCTL_DSP_CHANNELS ioctl. An example of a suitable driver is emu10k1
|
|
(used by Soundblaster Live! cards) from August 2001 or newer (ALSA CVS is
|
|
also supposed to work).

You need an AC3 capable sound card, with digital out (SP/DIF). The card's

driver must properly support the AFMT_AC3 format (C-Media does). Connect

your AC3 decoder to the SP/DIF output, and use the <option>-ac

hwac3</option> option. It is experimental but known to work with C-Media

cards and Soundblaster Live! + ALSA (but not OSS) drivers and DXR3/Hollywood+

AAC (Advanced Audio Coding) is an audio codec sometimes found in MOV and MP4

files. An open source decoder called FAAD is available from

<ulink url="http://www.audiocoding.com"/>. You can download the second

|
generation codec FAAD2 at their <ulink url="http://www.audiocoding.com/download.php">
|
|
download page</ulink>. Unfortunately FAAD2 1.1 does not compile under Linux, so you
|
|
will have to use the CVS version. Here's how:
|
|
<screen>
|
|
cvs -d:pserver:anonymous@cvs.audiocoding.com:/cvsroot/faac login

cvs -z3 -d:pserver:anonymous@cvs.audiocoding.com:/cvsroot/faac co faad2

cd faad2/

chmod +x bootstrap

./bootstrap

make

make install

Binaries are not available from audiocoding.com, but you can (apt-)get Debian

packages from <ulink url="http://marillat.free.fr">Christian Marillat's homepage</ulink>

VFW (Video for Windows) is the old Video API for Windows. Its codecs have
|
|
the <filename>.DLL</filename> or (rarely) <filename>.DRV</filename>
|
|
extension. If <application>MPlayer</application> fails at playing your AVI
|
|
with this kind of message:
|
|
<screen>UNKNOWN video codec: HFYU (0x55594648)</screen>
|
|
</para>
|
|
|
|
<para>
|
|
It means your AVI is encoded with a codec which has the HFYU fourcc (HFYU =
|
|
HuffYUV codec, DIV3 = DivX Low Motion, etc.). Now that you know this, you
|
|
have to find out which DLL Windows loads in order to play this file. In our
|
|
case, the <filename>system.ini</filename> contains this information in a
|
|
line that reads:
|
|
<programlisting>VIDC.HFYU=huffyuv.dll</programlisting>
|
|
</para>
|
|
|
|
<para>
|
|
So you need the <filename>huffyuv.dll</filename> file. Note that the audio
|
|
codecs are specified by the MSACM prefix:
|
|
<programlisting>msacm.l3acm=L3codeca.acm</programlisting>
|

</para>

<para>

This is the MP3 codec. Now that you have all the necessary information
