[FFmpeg-devel] Optimised math functions in FFMPEG?

[Paul Buxton]

Hi,

I have my filter working nicely but it is a little slow. I have
parallelised it where possible, but it is still a bit heavy. I am wondering
if there are any optimised implementations/approximations of some math
functions built in that I should use instead of the standard library
implementations.
Specifically any of
pow()
exp()
log()

I have done a quick grep of the code but can't see any likely contenders.

Thanks,
Paul
