NOTE: XAnim 2.70.6 OR GREATER IS REQUIRED FOR Creative CYUV SUPPORT!!!
These modules will add AVI support for the following Video Codecs:
+ Creative CYUV (CYUV) depth 16
CYUV support for XAnim is being provided as an optional machine
specific object module that is linked into XAnim at compile time.
1) The first step is figuring out which XAnim CYUV decompression
library module you need to obtain for your machine.
Below is a table that matches your machine/OS to which library
you need to download(ok, they're really object files).

There are some warnings that you can ignore.

------------ ----------------------------------
Amiga(gcc compiler?) xa1.0_cyuv_amiga.lha 1231
Thanks to Adrian (Sauron) Siemieniak for creating
and providing this object file derived from the
Sun 3x object module.
------------ ----------------------------------
NOTE: SunOS 4.1.3 uses AOUT and Sun Solaris used ELF. They're not
compatible.
NOTE: If your machine is not supported, it's because I don't have
physical access to that type of machine. There are a handful of options
available to you(not all of them may be feasible)
a) Permanently loan me that type of machine so that I may
compile a library module for that machine type. Please
contact me first and yes, I'd be surprised if someone
chose this option. :^)
b) Send me a cross-compiler for your machine type. Must
be a Sparc SunOS 4.1.x executable or more specifically
it must run on my machine. I'll do the compile and then
you'll need to verify that the resulting library module
works on your machine.
Yes, I know gcc can be a cross-compiler. No, I don't currently
have the time to setup it up for all the various platforms.
Since I'm not allowed to distribute the source code I can't login
to an account on a remote machine in order to do the compile.
Also, I personally can't give you a non-disclosure. You need
to contact Creative about licensing CYUV.
2) Obtaining the object files. Follow the steps below:
EITHER
/* NOT YET AVAILABLE VIA HTTP - HOPEFULLY SOON - USE FTP INSTEAD
1) Download the modules from one of the XAnim Web Pages
http://xanim.va.pubnix.com/home.html
http://smurfland.cit.buffalo.edu/xanim/home.html
http://www.tm.informatik.uni-frankfurt.de/xanim/
http://xanim.resnet.gatech.edu
*/
OR
1) cd into the XAnim directory on your machine
2) ftp xanim.va.pubnix.com OR ftp 199.170.0.28
3) user is "anonymous"
4) passwd is your email address
5) "type binary"VERY IMPORTANT
6) "cd modules"
7) "get LIB_NAME.Z"NOTE: the .Z at the end
8) "quit"
NOTE: LIB_NAME is obtained from the table in section 1 based
on the type of machine and OS you are running. If you don't
know, contact your system administrator or a coworker who
does know.
3) "uncompress LIB_NAME.Z"
This will create LIB_NAME from LIB_NAME.Z
3a) Put LIB_NAME into a directory called "mods" inside the xanim directory.
4) Edit Section III of either your Imakefile or Makefile(derived
from Makefile.unx). If you are not sure which one to
use then read the compile.help that came with xanim.
a) In Section III of either the Imakefile or Makefile
Uncomment out the following define:
XA_CYUV_DEF = -DXA_CYUV
and add LIB_NAME to the XA_CYUV_LIB define. For example
if you have Sun Sparc running SunOS 4.1.3 then you would
use the following:
XA_CYUV_LIB = mods/xa1.0_cyuv_sparcCOFF.o
For other machine/OS types, use the approriate xa1.0_cyuv_*.o file
listed in the table at the top of this readme.
NOTE: There is no "-" or anything other prefix. Just the object
file name.
b) If and ONLY if you are using the Imakefile(in other
words DON'T do this if you are using the Makefile(derived
from Makefile.unx)) then do the following:
"xmkmf"
c) Now(regardless of which makefile)
"touch xanim.h"
"make xanim"
NOTE: make sure you see -DXA_CYUV on the compile command lines
and make sure both xa_avi.c and xa_qt.c get recompiled.
d) You should use "make xaclean" instead of "make clean" if you
want to preserve the decompression modules.
5) Have fun. :^)
-------------------------------------------------------------------------
NOTES on how XAnim options affect CYUV on 8 bit Color displays/visuals.
None of these options matter on monochrome/TrueColor/DirectColor displays
and visuals.
With no options, XAnim will create a 256 entry RGB332 colormap
and dither to that.
xanim free_fall.avi
-F will turn off this dithering and XAnim will instead truncate
the 24bit RGB values down to the RGB332 colormap.(I see no real
advantage to this, which is why +F is on by default)
xanim -F free_fall.avi
The +CF4 option will TURN OFF the dithering by default. +CF4 causes
XAnim to scan the animation ahead of time and the select the
"best" 256 colors from the possible thousands sampled. These colors
may be further reduced depending on how many colors are still
available(ie not in use by other X11 applications).
xanim +CF4 free_fall.avi
If you specify +F AFTER the +CF4 option, dithering will be used
with the +CF4 option.
xanim +CF4 +F free_fall.avi
The -Cn option may be used with all of the above examples. -Cn tells
XAnim to create it's own colormap, giving it FULL USE of those
256 colors. Please note that it is up to your X11 Window Manager(NOT
XAnim) to install this colormap based on which window the Color Focus
is on. Normally, Color Focus follows the mouse pointer, but not
always.
xanim -Cn free_fall.avi
xanim -Cn +CF4 free_fall.avi
