[FFmpeg-devel] [PATCH] Per-frame metadata

I do not really see the bonus between

	if (av_size_mult(siezof(foo, n, &size) < 0)
	    return AVERROR(EINVAL);

and

	r = av_size_mult(siezof(foo, n, &size);
	if (r < 0)
	    return r;

The only benefit I see is in term of API uniformity, thus the question:

Do you think this is worth making mem.h depend on error.h?

I perfectly understand the argument, and in fact I agree with it. I will
wait a bit more to see if there are other remarks, especially from Michael.
