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

theorarm build
Hi all--
I tried building the ARM-optimized theora codec from the theorarm-
merge-branch, and encountered the following compile and runtime
problems before getting something to run. If there is another way to
build it, it would be nice to know, but I got the sense that its
current state in svn is incomplete.
I'm using a gcc cross-compiler for ARM on an x86 Linux PC. After
