* avcodec: Remove DCT, FFT, MDCT and RDFTAndreas Rheinhardt2023-10-011-62/+0
| | | | | | | | | | | | | They were replaced by TX from libavutil; the tremendous work to get to this point (both creating TX as well as porting the users of the components removed in this commit) was completely performed by Lynne alone. Removing the subsystems from configure may break some command lines, because the --disable-fft etc. options are no longer recognized.

* avcodec: Remove the FFT_FIXED_32 defineAndreas Rheinhardt2021-08-051-4/+0
| | | | | | | | 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>

* fft: remove 16-bit FFT and MDCT codeLynne2021-01-141-28/+1
| | | | | | 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.

| * Rename CONFIG_FFT_FLOAT ---> FFT_FLOATDiego Biurrun2014-01-061-2/+2
| | | | | | | | | | The define does not originate from configure, so it should not have a name that is CONFIG_-prefixed.
