Subject: [FFmpeg-devel] [PATCH 1/5] avutil/rational: add av_abs_q
Date: Wed, 27 Sep 2023 12:03:52 +0200
Message-ID: <20230927100630.50510-2-ffmpeg@haasn.xyz> (raw)
In-Reply-To: <20230927100630.50510-1-ffmpeg@haasn.xyz>

From: Niklas Haas <git@haasn.dev>

Seems like an obvious utility function to be missing, and useful in at
least several places in the code.
