Robert Edele	561a18d3ba	Snow mmx + sse2 part 2 Patch by Robert Edele, yartrebo <<at>> earthlink <<dot>> net Originally committed as revision 5184 to svn://svn.ffmpeg.org/ffmpeg/trunk	19 years ago
Robert Edele	059715a41c	First part of a series of speed-enchancing patches. This one sets up a snow.h and makes snow use the dsputil function pointer framework to access the three functions that will be implemented in asm in the other parts of the patchset.

Michael Niedermayer	b44985ba12	store the number of runs to avoid storing the last run value about 10% lower bitrate for -qscale 32 (forman & some music video) worst case bitrate increase <0.1% (lossless or low qscale) and now the bad news, even though this just adds a single subtraction and an if() into the medium sized unpack_coeffs() loop and the if() will only be false once per unpac_coeff() call, gcc produces 50% slower code, i didnt look at the generated asm yet, not sure if i want to ...
