* 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.

* avfilter/vsrc_mandelbrot: avoid sqrt for epsilon calculationGanesh Ajjanagadde2015-11-24
| | | | | | | | | | | | | | | | | | | | | | | | | | 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. Tested on x86-64, Haswell, GNU/Linux.
