Clément Bœsch f679711c1b checkasm: add vf_nlmeans test for ssd_integral_image 2018-05-08 10:28:06 +02:00
Clément Bœsch 5a71bce371 lavfi/nlmeans: add AArch64 SIMD for compute_safe_ssd_integral_image 
ssd_integral_image_c: 49204.6
ssd_integral_image_neon: 28346.8

Clément Bœsch 5ba14f4f1a lavfi/nlmeans: use ptrdiff_t for linesizes 
Similarly to previous commit, this will help writing SIMD code by not
having manual zero-extension in SIMD code

Clément Bœsch 26f02c51ce lavfi/nlmeans: add SIMD-friendly assumptions for compute_safe_ssd_integral_image 
SIMD code will not have to deal with padding itself. Overwriting in that
function may have been possible but involve large overreading of the
sources. Instead, we simply make sure the width to process is always a
multiple of 16. Additionally, there must be some actual area to process
so the SIMD code can have its boundary checks after processing the first
pixels.

Clément Bœsch f1248b7795 lavfi/nlmeans: random code shuffling to help compiler 
This makes nlmeans_slice() slightly faster at least on GCC 7.3.

Gyan Doshi 0683ad709b avformat/segafilmenc - set keyframe bit correctly 
As per
https://web.archive.org/web/20020803104640/http://www.pcisys.net:80/~melanson/codecs/film-format.txt,

the top bit of the info1 chunk is set as 1 for inter-coded frames and 0
otherwise.

Michael Niedermayer 3543522d20 avcodec/jpeg2000dec: Reduce the number of tile parts allocated 
This is large enough for all jpeg2000 files i tested. If some need more then this
should be changed to dynamic allocation. Dynamic allocation would need to be done
carefully as these are many relatively small arrays so repeatly reallocating them
would not be good.
The decrease is a clean and simple solution assuming it works for all files.
