Lynne	89a9042291	lavc/avfft: fix RDFT wrapper stride Per the lavu/tx docs: > * For forward transforms (R2C), stride must be the spacing between two > * samples in bytes. For inverse transforms, the stride must be set > * to the spacing between two complex values in bytes. The code did the reverse. The stride parameter is currently not respected for RDFT transforms, but has to be correct, for a potential future change.	9 months ago
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.
