Loren Merritt	b9fa32082c	exploit mdct symmetry 2% faster vorbis on conroe, k8. 7% on celeron. Originally committed as revision 14207 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
Loren Merritt	f27e1d645e	simplify vorbis windowing Originally committed as revision 14205 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
Kostya Shishkov	bb68f8a2b6	Monkey's Audio decoder vector functions work on input with length a multiple of 16. Reflect that fact in the documentation for them. Originally committed as revision 14148 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago

Kostya Shishkov	88c0536a42	Add several vector functions used by Monkey's Audio decoder to dsputil Originally committed as revision 14081 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
Alexander Strange	f67a10cd0c	Define mm_flags/support to be 0 on architectures where they don't exist. Make sure we don't try to set them if that's the case. This lets dct-test and fft-test build with --disable-mmx on x86, but not yet on ARM. Originally committed as revision 13957 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago

Aurelien Jacobs	49c35f16fc	Fix compilation on powerpc. DECLARE_ALIGNED_8 is not defined at that point, but this code is powerpc only, so it's really equivalent to DECLARE_ALIGNED(16... Originally committed as revision 12313 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
