I know. I had adjusted your first set of patches and changed the av_log
into

av_log(NULL,AV_LOG_DEBUG,"loudness=%f => %f => volume=%f\n", loudness,
	new_volume, pow(10, new_volume / 20));

But I lost that adjustment when I applied your second set of patches.

BTW: real life testing in Kansas went smoothly. The users did not even
notice the difference.
