* avcodec: remove deprecated FF_API_AVFFTJames Almer2025-03-281-268/+0
| | | | | | Deprecated since 2023-09-01. Signed-off-by: James Almer <jamrial@gmail.com>
* lavc/avfft: fix RDFT wrapper strideLynne2024-04-101-1/+1
| | | | | | | | | | | | 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.
* avfft: avoid overreads with RDFT API usersLynne2024-02-091-6/+25
| | | | | | | | | | 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.

* avutil/mem: Don't include avutil.hAndreas Rheinhardt2023-09-071-3/+4
| | | | | | | | | It is not necessary at all. So remove it. This also breaks an inclusion cycle mem.h->avutil.h->common.h->mem.h. Reviewed-by: Paul B Mahol <onemda@gmail.com> Reviewed-by: Michael Niedermayer <michael@niedermayer.cc> Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
