[FFmpeg-devel] [PATCH] examples/decoding_encoding: remove unused variable "size"

That is clearly wrong. I believe your shared object is badly linked. It
should have -lm in its NEEDED fields.

I forgot that, indeed. Then -lm is necessary. And -lm is specified by the
standard:

-l m
	This option shall make available all interfaces referenced in
	<math.h>, <complex.h>, and <fenv.h>.

And the example should include math.h too, IMHO.
