* avcodec: Remove DCT, FFT, MDCT and RDFTAndreas Rheinhardt2023-10-011-160/+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.

* libavcodec: Set hidden visibility on global symbols accessed from AArch64 ↵Martin Storsjö2022-09-021-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | assembly The AArch64 assembly accesses those symbols directly, without indirection via e.g. the GOT on ELF. In order for this not to require text relocations, those symbols need to be resolved fully at link time, i.e. those symbols can't be interposable. Normally, so far, this is achieved when linking shared libraries in two ways; we have a version script (libavcodec/libavcodec.v) which marks all symbols that don't start with av* as local. Additionally, we try to add -Wl,-Bsymbolic to the linker options if supported, making sure that such symbol references are resolved fully at link time, instead of making them interposable. When the libavcodec static library is linked into another shared library, there's no guarantee that it uses similar options (even though that would be favourable), which would end up requiring text relocations in the AArch64 assembly. Explicitly mark the symbols that are accessed from AArch64 assembly as hidden, so that they are resolved fully at link time even without the version script and -Wl,-Bsymbolic.

* avcodec: Remove the FFT_FIXED_32 defineAndreas Rheinhardt2021-08-051-8/+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 codeLynne2021-01-141-9/+0
| | | | | | 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.
