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:
