Michael Niedermayer	90e9e94d0f	workaround gcc bug, untested as my gcc is not complaining Originally committed as revision 10236 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
Michael Niedermayer	cefa599953	optimize the first vertical lifting step, this also prevents another overflow, the last known possible overflow Originally committed as revision 10234 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago

Michael Niedermayer	629750290f	avoid overflow in the 3rd lifting step, this now needs mmx2 at minimum (patch for plain mmx support is welcome ...) Originally committed as revision 10226 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
Michael Niedermayer	b696a4c91d	avoid an overflow in the 1 horizontal lifting step Originally committed as revision 10225 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago

Michael Niedermayer	3e0f7126b5	update mmx code to latest snow changes note, the code likely can overflow and thus needs some more changes sse2 updated too but disabled as it is untested Originally committed as revision 10223 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
