* swresample/x86/resample: Remove obsolete MMXEXT functionsAndreas Rheinhardt2022-06-14
| | | | | | | | | | | 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 MMXEXT resamplers (which are overridden by SSE2) are truely ancient 32bit x86s they are removed.

* Include attributes.h directlyAndreas Rheinhardt2021-04-19
| | | | | | | | Some files currently rely on libavutil/cpu.h to include it for them; yet said file won't use include it any more after the currently deprecated functions are removed, so include attributes.h directly. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* swresample: Use channel count in rematrix initializationMarcin Gorzel2018-07-26
| | | | | | | | Rematrixing supports up to 64 channels. However, there is only a limited number of channel layouts defined. Since the in/out channel count is currently obtained from the channel layout, for undefined layouts (e.g. for 9, 10, 11 channels etc.) the rematrixing fails. This patch changes rematrix init methods to use in (used) and out channel count directly instead of computing it from channel layout. Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>
