Loren Merritt	6810b93a81	sse2 version of compute_autocorr(). 4x faster than c (somehow, even though doubles only allow 2x simd). overal flac encoding: 15-50% faster on core2, 4-11% on k8, 3-13% on p4. Originally committed as revision 10621 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago

Michael Niedermayer	d593e32983	use 16bit IDWT (a SIMD implementation of it should be >2x faster then with the old 32bit code) disable mmx/sse2 optimizations as they need a rewrite now Originally committed as revision 10218 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
Michael Niedermayer	ce611a27be	Change rounding of the horizontal DWT to match the vertical one. This allows some simplifications and optimizations and should not have any effect on quality. Originally committed as revision 10172 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
