Michael Niedermayer	8bf16e677f	ffv1enc: allow encoding with 1 slice for CIF and smaller in version 3 the default is still 4 slices for any resolution, this just allows the user to force 1 slice. This in my quick test improves compression by 1% for a 320x240 sample Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Michael Niedermayer	c2cbc80ae9	ffv1enc: consider 2pass float rounding, fix loop Found-by: "Peter B." <pb@das-werkstatt.com> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago

Michael Niedermayer	e4255eaf47	ffv1: split decoder and encoder This is not based on lucas work due to code divergence (its less work this way than trying to merge from a split based on 2 years outdated code) Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago

Michael Niedermayer	54b2d317ed	ffv1: avoid checking a double for equality if 0.0 != 0.0 a out of array read would occur, equal checks with floating point may behave in such odd ways, though this is very unlikely in a real implementation of a compiler Fixes: CID718936 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
