idct8x8 C version in libtheora1.1 release
When using the IDCT routines, the C version [ lib/idct.c:
oc_idct8x8_c(ogg_int16_t _y[64],int _last_zzi)] in libtheora 1.1.1, the
decoded image is garbled. Is it functionally equivalent to the MMX optimized
version [lib/x86/mmxidct.c: oc_idct8x8_mmx(ogg_int16_t _y[64],int
_last_zzi)] ?
I used some of the Theora video files from here:

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

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
