* avfilter/af_dynaudnorm: remove wasteful powGanesh Ajjanagadde2015-11-26
| | | | | | | | This removes wasteful pow(x, 2.0) that although not terribly important for speed, is still useless. Reviewed-by: Paul B Mahol <onemda@gmail.com> Signed-off-by: Ganesh Ajjanagadde <gajjanagadde@gmail.com>
* avfilter/af_afade: improve accuracy and speed of gain computationGanesh Ajjanagadde2015-11-26
| | | | | | | | | | | | | | | | | | | Gain computation for various curves was being done in a needlessly inaccurate fashion. Of course these are all subjective curves, but when a curve is advertised to the user, it should be matched as closely as possible within the limitations of libm. In particular, the constants kept here were pretty inaccurate for double precision. Speed improvements are mainly due to the avoidance of pow, the most notorious of the libm functions in terms of performance. To be fair, it is the GNU libm that is among the worst, but it is not really GNU libm's fault since others simply yield a higher error as measured in ULP. "Magic" constants are also accordingly documented, since they take at least a minute of thought for a casual reader.

* avfilter/vsrc_mandelbrot: change sin to sinf for color computationGanesh Ajjanagadde2015-11-24
| | | | | | | | | | | | | | | | | | | | | | | | | | lrintf is anyway used, suggesting we only care up to floating precision. Rurthermore, there is a compat hack in avutil/libm for this function, and it is used in avcodec/aacps_tablegen.h. This yields a non-negligible speedup.

| | | | | | | | | | | | | | | | | | | | | | | | | | This rewrites into a similar expression avoiding sqrt. Similarity is assured since sqrt(x^2 + y^2)/(x+y) lies in [1/sqrt(2), 1] for x, y > 0.
