avfilter/vf_removegrain: add x86 and x86_64 SSE2 functions · bff72426

James Darnley authored Jul 14, 2015

Speed of all modes increased by a factor between 7.4 and 19.8 largely depending
on whether bytes are unpacked into words. Modes 2, 3, and 4 have been sped-up
by a factor of 43 (thanks quick sort!)

All modes are available on x86_64 but only modes 1, 10, 11, 12, 13, 14, 19, 20,
21, and 22 are available on x86 due to the number of SIMD registers used.

With a contribution from James Almer <jamrial@gmail.com>

vf_psnr: sse2 optimizations for sum-squared-error. · ae4c9dde

Ronald S. Bultje authored Jul 12, 2015

The internal line accumulator for 16bit can overflow, so I changed that
from int to uint64_t in the C code. The matching assembly looks a little
weird but output looks correct.

(avx2 should be trivial to add later.)
