idct/fdct.c function calls
Hi.
I am trying to find calls of idct/fdct.c functions by tracing png2theora.c calls.
But found only:
analyze.c:oc_dct_cost2()
Where and when idct/fdct/mmxidct/mmxfdct.c functions are used?
Mentions of "dct" word:
====
pacify at optima-amd64:/usr/src/libtheora-1.2.0alpha1/lib$ grep dct *.c | cut -f1 -d":" | uniq -c

3) Third question. How do you restore the original matrix after fdct and quantize ...
Used dequantize + idct?

VP3 IDCT
Hi,
Is there anything special I need to know about VP3's IDCT? I mean
besides the fact that there are separate IDCTs to handle sparse
coefficient matrices. Are the IDCT functions mathematically equivalent to
any textbook IDCT functions?
Thanks...

[LLVMdev] Use of -mllvm -debug (clang)
...use the -mllvm -debug option for clang but without much success. Do I need to build in any specific manner for this to work ?
On using -mllvm -debug as follows I get the error below.
$>clang -ccc-host-triple armv7-none-linux-gnueabi -mfloat-abi=softfp -mfpu=neon -mcpu=cortex-a9 -mllvm -debug fdct.i -S
clang (LLVM option parsing): Unknown command line argument '-debug'. Try: 'clang (LLVM option parsing) -help'
clang (LLVM option parsing): Did you mean '-lanum'?
Other options with -mllvm (e.g. print-after-all) work fine.
Thanks in advance.

libtheora 1.1 (Thusnelda) stable release
...this in a proper RDO framework
eliminates vast swaths of heuristics and fragile thresholds from the 1.0
encoder.
2. Better motion search
? The new motion search generates better results in less time, and
does not suffer from CPU spikes under heavy motion like the 1.0
encoder's did.
3. Better fDCT
? The 1.0 encoder's forward transform was not well-matched to the
inverse DCT used in the decoder, and was as a result responsible for
substantial loss of detail and texture at high rates. It has been
replaced with a forward DCT that gives much smaller round-trip error.
