* avcodec: Remove DCT, FFT, MDCT and RDFTAndreas Rheinhardt2023-10-011-47/+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/x86/fft: Remove obsolete 3dnow functionsAndreas Rheinhardt2022-06-221-14/+0
| | | | | | | | | | | x64 always has MMX, MMXEXT, SSE and SSE2 and this means that some functions for MMX, MMXEXT, SSE and 3dnow are always overridden by other functions (unless one e.g. explicitly disables SSE2). So given that the only systems which benefit from the 3dnow implementations are truely ancient 32bit AMD x86s they are removed. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
