Michael Niedermayer	62533eab6f	ffv1enc: use 64bit in maxsize calculation This isnt needed but it cant hurt, its also more consistent with how its calculated a few lines before. See: CID1108593 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago

Michael Niedermayer	abe76b851c	ffv1enc: Make ffv1.3 non experimental The fate tests change as they used 1.2 previously The increased size is due to: 32bit CRCs per slice by default (can be disabled), it adds slice headers to allow decoding one slice without the others an additional slice size field is added to make it possible to find slices within corrupted surroundings. these add up to about 57bit per slice more at 50 frames and 4 slices thats 1425 byte Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago

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
