<P>If you have a codec not listed here, and not supported yet, just read <A

|
|
|
|
<P><B><A NAME=2.1.2.1>2.1.2.1. DivX4</A></B></P>
|
|
|
|
<P>This section contains information about the DivX4 codec of
|
|
<A HREF="http://www.projectmayo.com">ProjectMayo</A>. Their first available alpha version was the OpenDivX 4.0
|
|
alpha 47 and 48. Support for this was/is included in <B>MPlayer</B>, and built by
|
|
default. We used to use its postprocessing code to optionally enhance visual
|
|
quality of MPEG1/2 movies. Now we use our own.</P>
|
|
|
|
<P>The new generation of this codec can even decode movies made with the
|
|
infamous DivX codec! And it's not everything, it's MUCH faster than the
|
|
traditional Win32 DivX DLL's. See below for configuration. The only
|
|
disadvantage of this codec is that it's currently closed-source. :(</P>
|
|
|
|
<P>The codec can be downloaded from the following URL:</P>
|
|
|
|
<P> <A HREF="http://download2.projectmayo.com/dnload/divx4linux/divx4linux-20010718.zip">http://download2.projectmayo.com/dnload/divx4linux/divx4linux-20010718.zip</A></P>
|
|
|
|
<P>No automatic installing available at this time, so install it manually,
|
|
EXACTLY as described here. Unpack it, and copy files to their place:</P>
|
|
|
|
<P><CODE>cp libdivxdecore.so.0.0.0 /usr/local/lib/<BR>
|
|
ln -s /usr/local/lib/libdivxdecore.so.0.0.0 /usr/local/lib/libdivxdecore.so.0<BR>
|
|
ln -s /usr/local/lib/libdivxdecore.so.0 /usr/local/lib/libdivxdecore.so<BR>
|
|
ldconfig<BR>
|
|
cp decore.h /usr/local/include/</CODE></P>
|
|
|
|
<P>Note: do NOT forget to add /usr/local/lib to your /etc/ld.so.conf !</P>
|
|
|
|
<P><B>MPlayer</B> autodetects if DivX4 is (properly) installed, just compile
|
|
as usual. If it doesn't detect it, you didn't install it exactly as above,
|
|
and/or has fucked up config (see last question of 5.1 section).</P>
|
|
|
|
<P>Using it is a bit tricky. As it conflicts with the old OpenDivX (it's API is
|
|
very similar to OpenDivX's), OpenDivX code is disabled, and the OpenDivX
|
|
driver calls this library too.</P>
|
|
|
|
<P>Generally we can pinpoint this issue to that you have two options to use
|
|
this codec:</P>
|
|
|

|
|
<TD><FONT face="Verdana, Arial, Helvetica, sans-serif" size=2>using divx4 codec as a new version of OpenDivX.
|
|
in this case it produces YV12 image in its own buffer,
|
|
and <B>MPlayer</B> (libvo) does colorspace conversion. (<B>RECOMMENDED!</B>)</TD><TR>

<TD><FONT face="Verdana, Arial, Helvetica, sans-serif" size=2>using divx4 codec's colorspace conversion.
|
|
in this mode, you can use YUY2/UYVY too.</TD></TR>
|
|
</TABLE></P>
|
|
|
|
<P>The 'odivx' 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 'divx4'
|
|
method. For RGB modes you can choose freely, their speed is same, maybe
|
|
differ according to the current bpp.</P>
|
|
|
|
<P>Note: it supports postprocessing too, but range of values is strange: (TODO UPDATE)</P>

|
<P><B><A NAME=2.1.2.2>2.1.2.2. ffmpeg's DivX/libavcodec</A></B></P>
|
|
|
|
<P>Beginning with version 0.4.2 , <A HREF="http://ffmpeg.sourceforge.net">ffmpeg</A> contains an <B>opensource</B> DivX codec,
|
|
which is compatible with the traditional DivX. <B>MPlayer</B> supports this codec,
|
|
and this makes it possible to <B>watch DivX/DivX4 movies on non-x86 platforms</B>,
|
|
and gain much faster <B>DivX/DivX4</B> decoding speed than the Win32 codecs and
|
|
the original DivX4 library has!<BR>
|
|
It was removed from <B>MPlayer</B>'s cvs tree, you have to download it
|
|
manually directly from <B>FFmpeg</B>'s tree:</P>
|
|
|
|
<P><CODE>
|
|
cvs -d:pserver:anonymous@cvs.ffmpeg.sourceforge.net:/cvsroot/ffmpeg login<BR>
|
|
cvs -d:pserver:anonymous@cvs.ffmpeg.sourceforge.net:/cvsroot/ffmpeg co ffmpeg
|
|
</CODE></P>
|
|
|
|
<P>Note: <I>if you copy with CVS subdirs, next time it's enough to do
|
|
'cvs update'.</I></P>
|
|
|
|
<P>Now, move the newly downloaded ffmpeg source's <B>libavcodec</B> directory,
|
|
(with all it's subdirectories) to <B>MPlayer</B>'s tree, so it will look
|
|
like this:</P>
|
|
|
|
<P> <CODE>main/libavcodec</CODE></P>
|
|
|
|
<P>Symlinking is NOT enough, you have to copy/move it!!!</P>
|
|
|
|
<P>./configure detects if it can be built. The codec also <B>supports
|
|
postprocessing!</B></P>
|
|
|
|
<P>In order to use it, refresh your codecs.conf file, and do as the manpage,
|
|
or the example.conf says (the -vfm option).</P>
|
|
|
|
<P>To achieve the <B>greatest speed</B> on my K6, I remove the
|
|
<CODE>ffmpeg12</CODE> section from codecs.conf (this codec isn't optimized, and
|
|
libmpeg2 is twice as fast), and place <CODE>vfm=5</CODE> in my config file.
|
|
Then <B>MPlayer</B> always uses <B>ffdivx/ffodivx</B> to decode
|
|
<B>DivX/DivX4</B> files, and libmpeg2 for MPEG1/2 . With this and my Matrox G400, I can view even the
|
|
highest resolution DivX/DivX4 movies on my K6/2 500, without framedrop.</P>
|
|
|
|
|
|
<P><B><A NAME=2.1.2.3>2.1.2.3. Hardware AC3 decoding</A></B></P>
|
|
|
|
<P>You'll need an AC3 capable soundcard, with digital out (SP/DIF). The
|
|
card's driver must support the AFMT_AC3 format (like SB Live! does).
|
|
Connect your AC3 decoder to the SP/DIF output, and use the '-ac hwac3'
|
|
option. It may or may not work (experimental). (probably won't...)</P>
|
|
|
|
|
|
<P><B><A NAME=2.1.2.4>2.1.2.4. XAnim codecs</A></B></P>
|
|
|
|
<P>Foreword: using (some) XAnim codecs with other program than XAnim, is
|
|
<B><I>ILLEGAL</I></B>. It is <B>YOUR</B> responsibility to read its license,
|
|
and do accordingly. The authors of <B>MPlayer</B> can't be held responsible for
|
|
any unlawful act of the user.</P>
|
|
|
|
<P>So yes, <B>MPlayer</B> can use XAnim's codecs for decoding. It's very
|
|
easy to enable them:</P>
|
|
|
|
<P>
|
|
<UL>
|
|
<LI>download the codecs you wish to use from the
|
|
<A HREF="http://xanim.va.pubnix.com">XAnim site</A>. The <B>3ivx</B> codec
|
|
isn't there, so download it from the <A HREF="http://www.3ivx.com">3ivx site</A>.</LI>
|
|
|
|
<LI>copy the codecs, or make symlinks for them to <CODE>/usr/lib/xanim/mods</CODE> .
|
|
Accordingly :<BR><CODE>ln -s vid_cvid_2.1_linuxELFx86c6.xa vid_cvid.xa</CODE>
|
|
for all of them.<BR>You can define another search path in xacodec.c:
|
|
<CODE>#define XACODEC_PATH "/usr/lib/xanim/mods"</CODE>.</LI>
|
|
</UL>
|
|
</P>
|
|
|
|
<P>They are video codec family number 10, so you may want to use <CODE>-vfm 10</CODE>
|
|
option to tell <B>MPlayer</B> to use them if possible.</P>
|
|
|
|
<P>Tested codecs are: <B>Indeo 3.2</B>, <B>4.1</B>, <B>5.0</B>, <B>CVID</B>, <B>3ivX</B>, <B>h263</B>.</P>

|
|
|
|
<P><A HREF="http://mad.sourceforge.net">libmad</A> is a multiplatform MPEG audio
|

<P>To enable support, compile with the <CODE>--enable-mad</CODE> configure

<P><B><A NAME=2.1.4>2.1.4. Codec importing howto</A></B></P>
|
|
|
|
<P><B><A NAME=2.1.4.1>2.1.4.1. VFW codecs</A></B></P>
|
|
|
|
<P>VfW (Video for Windows) is the old Video API for Windows. Its codecs have
|
|
the .DLL or (rarely) .DRV extension.
|
|
If <B>MPlayer</B> fails with your AVI:</P>
|
|
|
|
<P> <CODE>UNKNOWN video codec: HFYU (0x55594648)</CODE></P>
|
|
|
|
<P>It means your AVI is encoded with a codec which has the HFYU fourcc (HFYU =
|
|
HuffYUV codec, DIV3 = DivX Low Motion, etc...). Now that we know this, we'll
|
|
have to find out which DLL Windows loads in order to play this file. In our
|
|
case, the system.ini contains this (with many others):</P>
|
|
|
|
<P> <CODE>VIDC.HFYU=huffyuv.dll</CODE></P>
|
|
|
|
<P>So we'll need the huffyuv.dll file. Note that the audio codecs are specified
|
|
with the MSACM prefix:</P>
|
|
|
|
<P> <CODE>msacm.l3acm=L3codeca.acm</CODE></P>
|
|
|
|
|
|
<P>This is the MP3 codec.
|
|
So, now we have all the info needed (fourcc, codec file, sample AVI), submit
|
|
your codec support request in mail, and upload these files to the FTP:</P>
|
|
|
|
<P> <CODE>ftp://ftp.mplayerhq.hu/MPlayer/incoming/[codecname]/</CODE></P>
|
|
|
|
|
|
<P><B><A NAME=2.1.4.2>2.1.4.2. DirectShow codecs</A></B></P>
|
|
|
|
<P>DirectShow is the newer Video API, which is even worse than its predecessor.
|
|
Things are harder with DirectShow, since
|
|
<UL>
|
|
<LI>system.ini doesn't contain the needed information, instead it's stored in
|
|
the registry :(
|
|
<LI>we'll need the GUID of the codec.
|
|
</UL></P>
|
|
|
|
<P>So let's search that goddamn registry..
|
|
<UL>
|
|
<LI>Start 'regedit'
|
|
<LI>press ctrl-f, disable the first two checkbox, and enable the third. Type
|
|
the fourcc of the codec. (for ex.: TM20)
|
|
<LI>you should see a field which contains the path and filename
|
|
(for ex. : C:\WINDOWS\SYSTEM\TM20DEC.AX)
|
|
<LI>now that we have the file, we'll need the GUID. Try searching again, but
|
|
now we'll search for the codec's name, not the fourcc. Its name can be acquired
|
|
when Media Player is playing that file, by checking File/Properties/Advanced.
|
|
If not, bad luck ;) Try guessing.
|
|
(for ex. search for : TrueMotion)
|
|
<LI>if found (in registry), there should be a FriendlyName field, and a CLSID
|
|
field. Write down that 16 byte of CLSID, this is the GUID required by us.
|
|
</UL></P>
|
|
|
|
<P>NOTE: if searching fails, try to enable all the checkboxes.. you may have
|
|
false hits, but maybe you'll have the right, too...</P>
|
|
<P>NOTE: dump that M$ shit.</P>
|
|
|
|
|
|
<P>So, now we have all the info needed (fourcc, GUID, codec file, sample AVI),
|
|
submit your codec support request in mail, and upload these files to the FTP:<BR>
|
|
ftp://ftp.mplayerhq.hu/MPlayer/incoming/[codecname]/</P>
