Lynne	90adef99ca	avfft: avoid overreads with RDFT API users The new API requires an extra array member at the very end, which old API users did not do. This disables in-place RDFT transforms and instead does the transform out of place by copying once, there shouldn't be a significant loss of speed as our in-place FFT requires a reorder which is likely more expensive in the majority of cases to do.	11 months ago

Andreas Rheinhardt	e3b355c0be	avutil/mem: Don't include avutil.h It is not necessary at all. So remove it. This also breaks an inclusion cycle mem.h->avutil.h->common.h->mem.h.

Mans Rullgard	0aded9484d	Move dct and rdft definitions to separate files This leaves fft.h with only the core FFT and MDCT definitions thus making it more managable. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
