avfilter/vf_bwdif : Add a filter_line3 method for optimisation
4 juillet 2023, par John Coxavfilter/vf_bwdif : Add a filter_line3 method for optimisation
Add an optional filter_line3 to the available optimisations.
filter_line3 is equivalent to filter_line, memcpy, filter_line
filter_line shares quite a number of loads and some calculations in
common with its next iteration and testing shows that using aarch64
neon filter_line3s performance is 30% better than two filter_lines
and a memcpy.Adds a test for vf_bwdif filter_line3 to checkasm
Rounds job start lines down to a multiple of 4. This means that if
filter_line3 exists then filter_line will not sometimes be called
once at the end of a slice depending on thread count. The final slice
may do up to 3 extra lines but filter_edge is faster than filter_line
so it is unlikely to create any noticable thread load variation.Signed-off-by : John Cox <jc@kynesim.co.uk>

If so, could I avoid the transcoding by command ? Or it is a necessary ?
It it is a need, WHY ?
