* lavc/opus_celt: replace pow(2,x) by exp2f(x)Ganesh Ajjanagadde2016-01-221-1/+2
| | | | | | | Faster methods possible; since exponent is always a multiple of 1/8. Reviewed-by: Michael Niedermayer <michael@niedermayer.cc> Signed-off-by: Ganesh Ajjanagadde <gajjanagadde@gmail.com>
* lavc/opus_celt: replace pow by exp2Ganesh Ajjanagadde2015-12-171-2/+2
| | | | | | | | | | exp2 is faster. It may be possible to optimize further; e.g the exponents seem to be multiples of 0.25. This requires study though. Reviewed-by: Paul B Mahol <onemda@gmail.com> Signed-off-by: Ganesh Ajjanagadde <gajjanagadde@gmail.com>
