<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
|
2001-10-17 16:36:39 +00:00
|
|
|
default. We used to use its postprocessing code to optionally enhance visual
|
|
|
|
|
quality of MPEG1/2 movies. Now we use our own.</P>

2001-08-24 18:48:13 +00:00
|

|
|
|
|
|
<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><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>

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'

differ according to the current bpp.</P>

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

|
2001-11-20 14:19:31 +00:00
|
|
|
for 1.0 files is FFmpeg's H263 decoder, you can use it with the <CODE>-vc
|
|
|
|
|
ffh263</CODE> option (you'll need the newest libavcodec !). For 2.0 files, use
|
|
|
|
|
XAnim's H263 decoder codec (it supports fast YV12 output). You can call it with
|
|
|
|
|
the <CODE>-vc h263xa</CODE> option. Of course you have to compile XAnim codecs
|
|
|
|
|
support in, for details see the <A HREF=#2.2.1.3>XAnim video codecs</A>. If
|

and install it under <CODE>/usr/lib/win32</CODE> or wherever you store the

Win32 codecs. This latter codec doesn't support YV12 nor YUY2 only BGR modes,

thus usable only with the X11 and OpenGL outputs. Discouraged.</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>The audio codec used in VIVO files depends on whether it's a VIVO/1.0 or

|
|
|

VIVO/2.0 file. VIVO/1.0 files have <B>g.723</B> audio, and VIVO/2.0 files
|
|
|
|
|
have <B>Vivo Siren</B>. Currently none of them is supported, but you can

grab the g.723 codec from

<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>
|
2001-08-21 21:01:54 +00:00

<P> <CODE>UNKNOWN video codec: HFYU (0x55594648)</CODE></P>

2001-08-21 21:01:54 +00:00
|
|
|
|
2001-08-24 18:48:13 +00:00
|
|
|
<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>

|
|
|
|
2001-08-24 18:48:13 +00:00
|
|
|
<P>So we'll need the huffyuv.dll file. Note that the audio codecs are specified
|
|
|
|
|
with the MSACM prefix:</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>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.
|

|

|
|
2001-08-24 18:48:13 +00:00
|
|
|
<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>
