* avcodec: Remove the FFT_FIXED_32 defineAndreas Rheinhardt2021-08-05
| | | | | | | | Since the removal of the 16-bit FFT said define is unnecessary as FFT_FIXED_32 is always !FFT_FLOAT. But one wouldn't believe it when looking at the code. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avcodec/fft_template: Avoid useless functionAndreas Rheinhardt2021-01-29
| | | | | | | | ff_init_ff_cos_tabs is only used for the floating point FFT and only if hardcoded tables are disabled. Reviewed-by: Lynne <dev@lynne.ee> Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>
* fft: remove 16-bit FFT and MDCT codeLynne2021-01-14
| | | | | | No longer used by anything. Unfortunately the old FFT_FLOAT/FFT_FIXED_32 is left as-is. It's simply too much work for code meant to be all removed anyway.
* lavu/mem: move the DECLARE_ALIGNED macro family to mem_internal on next+1 bumpAnton Khirnov2021-01-01
| | | | They are not properly namespaced and not intended for public use.
* avcodec/fft: Add revtab32 for FFTs with more than 65536 samplesMichael Niedermayer2016-03-04
| | | | | | x86 optimizations are used only for the cases they support (<=65536 samples) Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>
