|
2002-04-08 16:40:52 +00:00
|
|
|
<A HREF="http://www.projectmayo.com">Project Mayo</A>. Their first available alpha version was OpenDivX 4.0
|
2002-06-28 06:07:46 +00:00
|
|
|
alpha 47 and 48. Support for this was included in <B>MPlayer</B> 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.</P>

|
|
|
<P>The new generation of this codec is called DivX4Linux 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 libavcodec.
|
|
|
|
|
Hence its usage as a decoder is <B>DISCOURAGED</B>. However, it is useful for
|
|
|
|
|
encoding. One disadvantage of this codec is that it is currently closed source.</P>

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

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 <CODE>-vc divx4</CODE>

method. For RGB modes the speed is the same, differing at best

according to your current color depth.</P>

We handle buggy MPEG 1/2 video files by catching sig11 (segmentation fault),
|
2002-04-08 16:40:52 +00:00

and quickly reinitializing the codec, continuing exactly from where the failure

<P>VFW (Video for Windows) is the old Video API for Windows. Its codecs have
|
2001-08-24 18:48:13 +00:00
|
|
|
the .DLL or (rarely) .DRV extension.
|
2002-04-08 16:40:52 +00:00
|
|
|
If <B>MPlayer</B> fails at playing your AVI with this kind of message:</P>
|
2001-08-21 21:01:54 +00:00
|
|
|
|
2001-08-24 18:48:13 +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 =
|
2002-04-08 16:40:52 +00:00
|
|
|
HuffYUV codec, DIV3 = DivX Low Motion, etc...). Now that you know this, you
|
2001-08-24 18:48:13 +00:00
|
|
|
have to find out which DLL Windows loads in order to play this file. In our
|
2002-04-08 16:40:52 +00:00
|
|
|
case, the <CODE>system.ini</CODE> contains this information in a line that reads:</P>
|
2001-08-23 17:08:46 +00:00
|
|
|
|
2001-08-24 18:48:13 +00:00
|
|
|
<P> <CODE>VIDC.HFYU=huffyuv.dll</CODE></P>
|
2001-08-23 17:08:46 +00:00
|
|
|
|
2002-04-08 16:40:52 +00:00
|
|
|
<P>So you need the <CODE>huffyuv.dll</CODE> file. Note that the audio codecs are
|
|
|
|
|
specified by the MSACM prefix:</P>
|
2001-08-23 17:08:46 +00:00

|
|
|
|
|
|
|
|
2001-08-24 18:48:13 +00:00
|
|
|
<P>This is the MP3 codec.

2002-04-08 16:40:52 +00:00

Now that you have all the necessary information (fourcc, codec file, sample AVI),
|
|

submit your codec support request by mail, and upload these files to the FTP site:</P>

<P>DirectShow is the newer Video API, which is even worse than its predecessor.
|
2002-04-08 16:40:52 +00:00
|
|
|
Things are harder with DirectShow, since</P>

<LI>Press <CODE>Ctrl-f</CODE>, disable the first two checkboxes, and enable the

third. Type in the fourcc of the codec (e.g. TM20).

<LI>You should see a field which contains the path and the filename

(e.g. <CODE>C:\WINDOWS\SYSTEM\TM20DEC.AX</CODE>).
|
|
|
|
|
<LI>Now that you have the file, we need the GUID. Try searching again, but
|
|
|
|
|
now search for the codec's name, not the fourcc. Its name can be acquired
|
|
|
|
|
when Media Player is playing the file, by checking File->Properties->Advanced.
|
|
|
|
|
If not, you are out of luck. Try guessing (e.g. search for TrueMotion).
|
|
|
|
|
<LI>If the GUID is found you should see a FriendlyName and a CLSID
|
|
|
|
|
field. Write down the 16 byte CLSID, this is the GUID we need.
