Hello,

but i recieve an error:
In file included from libavutil/internal.h:166:0,
                 from newmain.c:30:
libavutil/libm.h:54:32: error: static declaration of ‘cbrt’ follows
non-static declaration
 static av_always_inline double cbrt(double x)
                                ^

I am using the flag -lavutil.
