[FFmpeg-devel] [PATCH] avcodec/utils: only warn when passed invalid lowres value

[Aman Gupta]

From: Aman Gupta <aman at tmm1.net>

This makes it easier to use the lowres option when dealing with input
files in different codecs. If the codec doesn't support lowres=1 for
instance, it will throw a warning and use lowres=0 instead of erroring
out completely.
