* Lancer is based on aotuv-r1_20051117 now.
* add SSE optiomizations to _vp_couple.
* add the dividing code of multi channel processing to xmmlib.h.
* _vp_quantize_couple_memo, _vp_quantize_couple_sort is multithreaded under the OpenMP.

* mapping0_forward is more parallelized.
* Buffered delay writer for Ogg stream is implemented. It makes possible that floor1_encode in the code book.* is parallelized.
* floor1_encode is able to execute in the parallel processing now.
* _vp_couple is parallelized.

Divide by zero in accumulate_fit
...S) haven't been running correctly. In a few
debugging sessions, I've found that I'm getting a divide by zero exception.
The exception happens in accumulate_fit (floor1.c), line 455:
int weight=nb*info->twofitweight/na;
Here is the call stack:
accumulate_fit
floot1_fit
mapping0_forward
vorbis_analysis
oe_encode
main
The error happens very early: the first call to vorbis_analysis (third iter.
through the main encode loop) in oe_encode. Reproducable with every wav I
feed it.
Can anyone help?
<p>

gcc 2.95.2/irix/Laguerre_With_Deflation/inifinte loop
I built ogg vorbis from the rc1 cvs source on Irix 6.5.12
with gcc 2.95.2. Using oggenc I encoded about 8,000 aiff files
but found about a dozen where oggenc would go into an infinite
loop. I tracked the problem with Laguerre_With_Deflation() as far back
as
logmask being Inf in floor0_forward. I'm now building gcc 3.0 with the
expectation this is a compiler issue. If not, I'll back

Borland compiler issues
...loaded the nightly
CVS, but it seems unusable right now. The Windows SDK does not appear
to include source code or Borland compatible libraries.
One thing I've noticed about the nightly CVS code is that the nested
alloca() calls seem to confuse Borland's compiler. I had to change
code in mapping0_forward() from:
zerobundle[0]=alloca(sizeof(int)*vi->channels);
to:
z=alloca(sizeof(int)*vi->channels); /* int *z; */
zerobundle[0]=z;
I'm considering that yet another Borland compiler bug.
Another problem I found is that in vorbis_analysis_wrote(), the line...

Clean separation of encode and decode?
Is anybody interested in cleanly separating encode and decode in vorbis? I'm trying to take a stab at it myself from the head of cvs as of this morning, but it looks like a lot of files contain both encode-only and decode-only functions. An obvious one is mdct.c, which contains mdct_forward and mdct_backward (which isn't that big of a deal, since both are pretty well-contained, but it

encoder observation
Hello!
First of all a question:
When you make the encoder tables (ie: mode_e.h)
do you use the mapping0_forward function?
Because you made the encoder tables, and after this
you did a minor correction in the final beta4 ...
(this correction was:
additional[0]=fabs(additional[0]*scale);
in the mapping0_forward function)
(I see this was a bug, and the modification
was correct, but this correction caused an...
